Definitions
- the invention relates to a cover for growing bananas in particular.
- bananas are also sensitive to irradiation by ultraviolet “B” (UV “B”) (280-320 n) which results in the appearance of erythema on the skin of the banana (black spots) and which causes disappearance of chlorophyll (chlorosis). Bananas are also sensitive to infrared (heat) which can cause the same symptoms when the temperature of the fruit exceeds 35 ° C.
- a blue dye was then proposed (ophthalocianyl blue, blue overseas ”) which, introduced into the polyethylene sheaths, protects the bananas from burns.
- the invention provides a solution to the above problems by proposing a cover made of a multilayer plastic film of the type comprising an outer layer, a central layer and an inner layer, the central layer comprising a copolymer of ethylene and vinyl acetate. and at least one of the three layers comprising at least one light stabilizing agent and ultraviolet absorber, for growing bananas.
- the copolymer of ethylene and vinyl acetate contains less than 20% by volume, relative to the total volume of the copolymer, of vinyl acetate.
- the copolymer of ethylene and vinyl acetate comprises between approximately 9% and approximately 19% by volume of vinyl acetate relative to the total volume of the copolymer.
- only the central layer contains said at least one light stabilizing agent and UV absorber.
- only the outer layer contains said at least one light stabilizing agent and UV absorber.
- only the inner layer contains said at least one light stabilizing agent and UV absorber.
- only the outer and central layers contain said at least one light stabilizing agent and UV absorber.
- only the inner and central layers contain said at least one light stabilizer and UV absorber.
- the three layers contain said at least one light stabilizing agent and UV absorber.
- the light stabilizing and ultraviolet absorbing agent is 2-hydroxy-4-n-octoxy-benzophenone, which is associated with a light stabilizing agent, poly- (N- ⁇ -hydroxyethyl-2,2,6,6 -tetramethyl-4-hydroxy-piperidyl succinate), each in an amount of 0.1 to 2% by volume relative to the total volume of the copolymer.
- the central layer further comprises a slip agent such as an oleamide.
- the outer layer is composed of a low density, radical polyethylene having a melt index of less than 1.5 g / cm ⁇ / min and the inner layer is a low polyethylene radical density having a melt index greater than 4 g / cm 2 / min.
- the inner layer additionally contains an anti-fogging agent, such as a glycerol of mono-oleate.
- the outer layer contains a slip agent, such as an oleamide
- the inner layer contains a slip agent, such as an amine, and an anti-blocking agent such as synthetic silica.
- each layer independently of one another constituting the cover has a thickness of between approximately 5 and approximately 15 microns.
- the cover of the invention consists of a cylinder of approximately 50 cm in diameter and between approximately 140 cm and approximately 160 cm in height, perforated at its top by only about 80 cm.
- Figure 1 is a perspective view showing a mode of use of the cover according to the invention.
- Figure 2 is a vertical sectional view of the cover of the invention.
- Figure 3 is a side view of a standing cover according to a preferred embodiment of the invention.
- the invention provides a cover made of a plastic film with a positive greenhouse effect, that is to say promoting the growth of bananas by providing heat by reducing heat loss by radiation at night and during the day. lets through all visible light and a good part of UV “A” and which absorb UV “B” and reflects infrared (between 20 and 30%).
- FIG. 1 which shows a cover according to the invention in use, it can be seen that the cover 1 has an external face in contact with the external environment and an inner face in contact with the banana bunch (3).
- the cover 1 is tied by a means suitable for the pole 2 of the banana tree.
- the cover 1 consists of a multilayer plastic film illustrated in Figure 2.
- This plastic film is of the type consisting of an outer layer 4, which is the layer in contact with the external environment, a central layer 5 and d 'an inner layer 6 in contact with the banana diet.
- the cover 1 allows faster growth of bananas, growth directly linked to the amount of heat transmitted to the fruit, thanks to the presence of the central layer 5 consisting of a copolymer of ethylene and vinyl acetate which gives the plastic film a thermicity between 80% and 70%.
- the film therefore returns to the banana part of the infrared re-emitted at night by the fruit while returning the infrared during the day to the outside. This provides additional heat during the night.
- the ethylene-vinyl acetate copolymers have adhesive properties which make it difficult to use them when the amount by volume of vinyl acetate, relative to the total volume of the ethylene-vinyl acetate copolymer, exceeds 20%. It is therefore preferred that the central layer 5 of the film constituting the cover of the invention contains less than 20% by volume of vinyl acetate.
- the multilayer plastic film used in the invention will therefore preferably have a central layer 5 consisting of an ethylene-vinyl acetate copolymer containing between about 9% and about 19%, by volume relative to the total volume of the vinyl acetate copolymer.
- the cover of the invention absorbs harmful UV “B” while allowing much of the white light and UV "A” to pass through.
- the central layer of the cover of the invention may comprise an ultraviolet absorbing agent which absorbs a good part of the ultraviolet "B” and thus inhibits the cause of erythes, while allowing the component wavelengths to pass.
- white light including blue light
- UV "A and blue light 450 nm are the guarantees of a good healing of the erythema due to UV" B ". Taking advantage of all visible wavelengths, bananas can absorb what it needs, the hardness of the skin is then increased, that is to say that it has better resistance to impact, injury, the proliferation of different parasites and fungi.
- any suitable UV-absorbing agent "B” can be used in combination with the copolymer of ethylene and vinyl acetate.
- a preferred UV-absorbing agent “B” is one that not only absorbs UV “B” but also helps to stabilize the copolymer of ethylene and vinyl acetate in light, i.e. saying allows it to keep its mechanical qualities despite the irradiation with ultraviolet, 2-hydroxy-4-n-octoxy-benzophenone.
- This light stabilizer and UV absorber is most favorably used in combination with another light stabilizer poly- (N- ⁇ -hydroxyethyl-2,2,6,6,6 tetramethyl-4-hydroxy-piperidyl succinate).
- the effective and sufficient amounts of the light stabilizing agent and UV absorber and of the light stabilizing agent mentioned above are between 0.1 and 2% by volume for each of the agents relative to the volume copolymer of ethylene and vinyl acetate.
- this central layer consisting of a copolymer of ethlylene and vinyl acetate has adhesive properties which make it necessary to have an inner layer, that in contact with the fruit, in order to avoid that the cover in use does not stick to the fruit.
- This inner layer must also be transparent to white light and UV "A”. It may also contain a light stabilizer and UV absorber as well as a light stabilizer, for example those contained in the central layer and in the same proportions as in the central layer. It should also be relatively soft so as not to damage the fruit.
- this inner layer thus consists of a low-density, free-radical polyethylene.
- a preferred polyethylene has a melt index greater than 4 g / cm 2 / min.
- the inner layer further comprises an anti-fog agent.
- this anti-fogging agent allows, by modifying the surface tension properties of the film, a uniform distribution of the condensation water on the film, and thus, better transmission of the visible spectrum and of UV "A".
- This anti-fogging agent on the interior surface also ensures easier water runoff and thus reduces the risk of erythema by "magnifying glass effect”. It also reduces the phenomenon of dripping on the fruit by allowing easier water runoff.
- the presence of the anti-fogging agent therefore also contributes to better growth of the banana and to a better hardness of the skin of the banana.
- any suitable anti-fogging agent can be used in the inner layer but a preferred anti-fogging agent is mono-oleate glycerol.
- the inner layer of the plastic film constituting the cover of the invention may also comprise a slip agent such as amines and an anti-blocking agent making it possible to avoid the sticking of the two interior faces of the cover of the invention, during its storage and thus allow to easily open the cover for use.
- a slip agent such as amines
- an anti-blocking agent making it possible to avoid the sticking of the two interior faces of the cover of the invention, during its storage and thus allow to easily open the cover for use.
- a preferred anti-blocking agent is synthetic silica.
- the central layer is covered with an outer layer, it is ie that in contact with the ambient air, which must also let pass the white light and UV "A", like the other layers.
- this outer layer is composed of a low density polyethylene, radical and having a melt index of less than 1.5 g / cm 2 / min, in order to impart good mechanical properties to the film of the cover of the invention .
- this outer layer may also include the same light stabilizer and UV absorber and associated light stabilizer as those included in the central layer, that is to say say say 2-hydroxy-4-n-octoxy-benzo-phenone associated with poly- (N- ⁇ -hydroxyethyl-2,2, 6, 6 tetra-methyl-4-hydroxy-piperidyl succinate) and this in the same quantities only for the central layer.
- any other polymer and / or light stabilizing agent and UV absorber can be used insofar as they have the same function as polyethylene and the light stabilizing agents and UV absorber described above. .
- the outer film may include a slip agent such as an oleamide.
- the film making up the cover for growing bananas according to the invention is produced in a manner known per se in the art, that is to say for example by co-extrusion in three layers.
- its production is managed by computer, in order to guarantee a stability and a constancy of the thicknesses of each layer. This guarantees the dosage of inputs.
- the thickness of each layer constituting the film used in the invention is between approximately 5 and approximately 15 microns.
- the covers according to the invention will generally have the shape of a cylinder, with a diameter ⁇ of approximately 50 cm and a height H of between approximately 1.40 m and approximately 1.60 m.
- FIG. 3 represents a side view of a standing cover according to the invention
- the cover will only be perforated at its higher height on a height h of about 80 cm.
- This provides a "chimney effect" which promotes the evacuation of water to the outside and therefore contributes to the reduction of the risk of burns by reverberation of humidity, by magnifying glass effect and to the reduction of the risks of chlorosis. by reducing the heat in the enclosure during the day (by convection) as well as by a permanent rebalancing of the partial pressures of CO2 and O2.
- the perforations will have a diameter of 8 mm and each perforation will be at a distance d from the others of approximately 6 cm.
- Tests have been carried out in Guadeloupe, using the cover of the invention, and for comparison the blue polyethylene cover of the prior art and also by not using a cover.
- the sheath of the invention was as follows:
- outer layer thickness between 5 and 15 microns, composed of a low density, radical polyethylene, of a melt index of less than 1.5 g / cm 2 / min and, of a light stabilizer and absorber UV: 2-hydroxy-4-n-octoxy-benzophenone, in an amount of 0.1 to 2% by volume relative to the total volume of the polyethylene; and a light stabilizer: poly- (N-Co-hydroxyethyl-2,2,6,6-tetramethyl-4-hydroxy-piperidyl-succinate), in an amount of 0.1 to 2% by volume relative to the total volume of the polyethylene.
- central layer thickness between 5 and 15 microns, composed of a copolymer of ethylene and vinyl acetate containing between 9 and 19% by volume, relative to the total volume of copolymer, vinyl acetate, d 'a light stabilizer and UV absorber: 2-hydroxy-4-n-octoxy-benzophenone, in an amount of between 0.1 and 2% by volume relative to the volume of the copolymer, and of a stabilizer in the light: poly (N- ⁇ -hydroxy-ethyl-2,2, 6, 6-tetramethyl-4-hydroxy-piperidyl-succinate), in an amount of between 0.1 and 2% by volume relative to the total volume of the copolymer.
- inner layer thickness between 5 and 15 microns, composed of a low density polyethylene, free radical, with a melt index greater than 4 g / cm 2 / min, a light stabilizer and UV absorber : 2-hydroxy-4-n-octoxy-benzophenone, in an amount of between 0.1 and 2% by volume relative to the volume of polyethylene and of a light stabilizer: poly (N- ⁇ -hydroxy -ethyl-2,2,6,6-tetramethyl-4-hydroxy-piperidyl- succinate), in an amount between 0.1 and 2% by volume relative to the total volume of the polyethylene.
- the hardness modulus measurements are carried out by measuring the pressure at the surface of the skin for a constant penetration speed of 2 mm / s with a 20 mm 2 pellet.
- Table 1 below groups together the results obtained at 300 m altitude and Table 2 groups together the results obtained at 50 m altitude.
- the hardness modulus tends to become "uniform", between 1450 and 1550 g, and the growth rate increases to 0.29 mm / day.
- the cover of the invention can be adapted to the various banana growing sites.
- the UV absorber used in the invention transforms UV "B" into heat, that is to say into infrared and the copolymer constituting the central layer of vinyl acetate-ethylene returns these infrared.
- Example 1 we saw in Example 1 that in the so-called "lowland” zone, that is to say at an altitude of less than 100 m, the speed of fruit growth is already high and that the problem encountered is that of a hard skin of the fruit. Therefore, we will seek more in this area to promote the increase in the hardness of the skin than the growth of the fruit. The additional heat supply due to the transformation of UV "B" into heat is therefore not necessary.
- UV "B” is absorbed and transformed into heat (IR) as it passes through the outer layer.
- IR heat
- the vinyl acetate-ethylene copolymer contained in the central layer returns to the outside, during the day, this additional heat supply.
- the UV "B” through the core layer are converted into heat (IR) in the cen t ral layer and / or the inner layer and the presence of the ethylene-vinyl acetate copolymer in the layer central will return this additional heat supply to the fruit during the day.
- a central layer made of a positive greenhouse material here in an ethylene-vinyl acetate copolymer
- a UV absorber contained either in the three layers constituting the cover of the he invention, or in only one of these layers, makes it possible to adapt the cover of the invention to all the climatic situations encountered during the cultivation of fruits.
- the cover according to the invention contains a light stabilizing agent and UV absorber (with the associated light stabilizing agent) only in the central layer
- this cover will have the advantage that the inner layer, that is to say the one in contact with the fruit, will serve as an "insulating" layer compared to the central layer of ethylene-vinyl acetate copolymer, which will be hot.
- Tests were carried out on the planted (first cycle) which are reputed to be fragile plantations in two places, that is to say in the plain (altitude 30 m) and in the mountains (altitude 250 m).
- the cultivation was carried out from September to December, ie during the period of the year most favorable to the cultivation of bananas, but with this year problems of drought, especially in the plain.
- the observations were made by comparison of certain criteria between the diets raised under a blue sheath of the prior art and the high regimes under a sheath of the invention for the same cut flower interval (IFC).
- the cut flower interval is the time interval between the flowering of the banana tree and the cutting of the bananas.
- the difference in grade represents the difference in diameter of the fruit measured with the caliper between the fruit cultivated with the blue cover of the prior art and with the cover of the invention.
- the cover of the invention contained the light stabilizing agent and UV absorber and the associated agent described in Example 1 only in the central layer and the outer layer while at altitude, the cover of the invention contained the UV absorber and light stabilizing agent and the associated light stabilizing agent described in Example 1 only in the central layer and the inner layer.
- the photosynthetic activity is greater than with the blue polyethylene covers.
- the bananas lengthen more quickly, which allows a larger opening of the hands of the bottom of the regime and thus avoids injuries from one hand to the other. It is estimated that one hand / diet (about 1 kg) wastes due to this type of injury.
- any plastic film or combination of plastic films with a positive greenhouse effect, absorbing UV “B”, allowing UV “A” to pass and white light can be used to make a cover according to the invention.
- the cover of the invention can be used for growing other fruits than bananas, if appropriate. This is the case, in general, for any plant system with significant photosynthetic activity and of size compatible with the use of plastic covers.
- cover of the invention should have a very effective role in stimulating the growth of banana offspring when placed on the offspring.
- cover of the invention may also have other dimensions than those described here.
