Abstract
The present invention provides a production technology of fertilizer with a controlled release function. Paclobutrazol water solution, potassium chloride, borax, calcium carbonate, modified starch, bentonite, cement and dinitrocellulose are uniformly mixed with the water according to a weight ratio of 0.05 to 0.5: 15 to 20: 0.05 to 0.5: 25 to 35: 10 to 15: 15 to 20: 25 to 50: 10 to 25, and granules with the granule diameters of 2 to 3mm are obtained by squeezing and granulation. After the granules are maintained in steam of 160 DEG C for 20 minutes and are dried by placing under the normal temperature, a product of the present invention is obtained. The present invention has the advantages of simple production process, low material cost and obvious controlled release effect of the obtained fertilizer, slow controlled dissolution of functional substances can be realized by changing the compounding ratio of raw materials according to the requirements of the crops, and the high efficiency use of the functional substances can be promoted. The present invention is suitable for fruit trees, lawn and other plants.
Description
Technical field
The present invention relates to a kind of production technique of fertilizer, particularly relate to a kind of production technique of fertilizer with release-controlled function.
Background technology
Because release and release control fertilizer can be regulated nutrient releasing speed and crop regulation of fertilizer requirement basic synchronization, and can be disposable employed, thereby increase substantially utilization rate of fertilizer, labor savings, therefore, release and release control fertilizer development and Application and promote and to improve crop quality to improving the utilization of agricultural resources utilization rate, it is significant to alleviate environmental pollution.The nutrient controlled release of release and release control fertilizer has three kinds of modes, and one is to use organic nitrogen compound, and it two is packs, and it three is support methods, and main drawback is the cost height, is unfavorable for promoting.Chinese patent 981250165 discloses a kind of spherical internal film slow releasing lawn fertilizer, and fertilizer and growth regulator are slowly discharged, less wastage, and its validity period reaches 6 months.But the complex manufacturing of this kind fertilizer, production cost is higher, and the fertilizer rate of release is difficult for adjusting, so can not satisfy the demand rule of different plants to nutrient and growth regulator well.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, provide a kind of technology simple, cost is low, can satisfy the production technique of different plants to the fertilizer with release-controlled function of nutrient and growth regulator demand rule well.
The production technique of fertilizer with release-controlled function of the present invention is:
1) paclobutrazol is mixed with the aqueous solution of 5g/L, Repone K, borax, lime carbonate, treated starch, wilkinite, cement, Nitrocellulose are worn into 100～10 purpose powder respectively, press paclobutrazol: Repone K: borax: lime carbonate: treated starch: wilkinite: cement: Nitrocellulose=0.05～0.5: 15-20: 0.05～0.5: 25～35: 10～15: 15～20: 25～50: 10～25 weight ratio is mixed, add water and stir, and the adjustment water ratio is 7.5～10%;
2), get the particle of particle diameter 2～3mm with the said mixture extruder grain;
3) with above-mentioned particle in 160 ℃ of steam curings 20 minutes, place and promptly get fertilizer with release-controlled function of the present invention under the normal temperature after the drying.
Wherein, the effect of each feed composition is respectively, utilize stronger water-absorbent of wilkinite and swelling property, in the process of theing cement solidifies, the wilkinite water-swelling, cause many minute cracks on cement wrap surface, the passage of exchange of moisture is released the active substance that includes in formation and the external environment.Wilkinite also has a series of good physico-chemical properties such as stronger adsorptivity, dispersiveness, tackiness, cationic exchange, preserve moisture and fertility, and contain the required constant of plant and in feed composition, add the plasticity-that its effect of Nitrocellulose is an increase cement, so that granulating and forming, simultaneously, the back fertilizer quality of also can avoiding theing cement solidifies is too tight; Add lime carbonate as the water-soluble carrier material, purpose be because behind the incorporation of fertilizerin the soil, lime carbonate is decomposed by environmental attack gradually, in fertiliser granulates, form the cavity, make fertiliser granulates become a porous insert, make include functional mass can be evenly, discharge lentamente.And treated starch is different with the dissolution rate of lime carbonate in water, mixes the dissolution rate that uses easier control active function material; Repone K, borax and paclobutrazol are the active function material, and potash fertilizer and borax are the required topmost fertilizer of plant-growth, and paclobutrazol then is a plant-growth regulator.The purpose that adds Nitrocellulose is the plasticity before refinforced cement solidifies, and improves the parcel effect, and lowers the hardness after theing cement solidifies, and uses Nitrocellulose can also form the passage of active substance stripping in addition in particle.Adopting vapor cure in the technology of the present invention is to the cement solidifies in order to quicken, and gaps in cement surface in expansion process to guarantee wilkinite.
The advantage of the production technique of fertilizer with release-controlled function of the present invention is that technology is simple, be easy to control, can adjust the cooperation ratio of feed composition, come the dissolution rate of adjusting function material according to the crop needs, gained fertilizer control release effect is obvious, can be widely used in fruit tree, lawn and other plant.
Embodiment
Embodiment 1:
1) paclobutrazol is mixed with the aqueous solution of 5g/L, Repone K, borax, lime carbonate, treated starch, wilkinite, cement, Nitrocellulose are worn into 10 purpose powder respectively, amount by paclobutrazol 0.05 gram, Repone K 15 grams, borax 0.5 gram, lime carbonate 35 grams, treated starch 15 grams, wilkinite 15 grams, cement 30 grams, Nitrocellulose 10 grams is mixed, add water and stir, and the adjustment water ratio is 7.5%;
