Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pressure-sensitive adhesive sheet for seeding and raising seedlings used for seeding and raising seedlings of vegetables, flowers, etc., and particularly to a pressure-sensitive adhesive sheet for seeding and raising seedlings suitable for efficiently seeding green onion seeds at a desired site and at a desired density. .

[0002]

[Prior art]

 At present, in the hydroponic cultivation of green onions, it is common to sow seeds into seedling boxes by hand or use an automatic seeder. Of these, in the case of manual sowing, the seeding density tends to be uneven, and each section (planting unit) used when tearing the mat small pieces along the perforations provided between the planting units of the nursery mat during planting Since the number of seeds fluctuates, thinning work after germination was essential to equalize the crop density at harvest. In addition, in the case of sowing work using an automatic seeder, although seeding density is relatively uniform, seedlings grown from seeds sown near the perforations of the seedling mat may have root damage during planting. Since the subsequent growth was hindered by such factors, thinning work was still necessary.

In order to solve the above problems, the inventors of the present invention previously provided a plurality of planting units on a water-soluble or water-dispersible support, and each planting unit. We proposed an adhesive sheet for seeding and raising seedlings of green onions, which was coated with a dot-like adhesive for each plant, so that the onion seeds could be evenly loaded in each of the above-mentioned planting units (Practical application 1-084551).

[0004]

[Problems to be solved by the device]

 However, in the pressure-sensitive adhesive sheet, if the mutual spacing of the plurality of dot-shaped adhesives applied for each planting unit is too wide, when the sheet is placed on the seedling-growing mat, the end portion of each planting unit As the distance between the point adhesive and the perforation of the mat becomes closer, the roots grown from the green onion seeds mounted on the point adhesive may extend through the perforations of the seedling raising mat to the adjacent planting unit. is there. Such roots are damaged when the seedling mats are torn off along the perforations during planting, which prevents normal growth.

Further, if the distance between the plurality of point adhesives coated in each planting unit is too close to each other, the seed density becomes large, which hinders the growth of each other, resulting in uneven growth. However, there is a problem that the efficiency of various operations such as lower leaf removal work after harvesting is reduced.

[0006] The object of the present invention is to solve the problems of the above-mentioned conventional techniques and efficiently sow onion seeds at a desired site at a desired density to improve the efficiency of various cultivation work. Another object of the present invention is to provide a pressure-sensitive adhesive sheet for green onion seedling raising, which is suitable for improving the quality of crops to be harvested.

[0007]

[Means for Solving the Problems]

The above-mentioned object is to provide a pressure-sensitive adhesive sheet for seeding and raising seedlings, comprising a plurality of plant-forming units provided at desired positions on a water-soluble or water-dispersible sheet-like support, and a plurality of point-like adhesives provided for each plant-forming unit. In the range of 0.5 to 1.2 mm ² of the adhesive coating area per point of the above point adhesive, the number of dots of the point adhesive applied per planting unit is 8 The pressure-sensitive adhesive sheet for seeding and raising seedlings, wherein the distance between the pressure-sensitive adhesives is in the range of 8 to 12 mm, and a plurality of dot-shaped pressure-sensitive adhesives in the planting unit are arranged so as to form a void in the center. Can be achieved by

[0008]

[Action]

 The green onion seeds have a half-moon shape with a length of about 2 mm and a height of about 1.5 mm. The cultivation method is a dense cultivation method in which 15 to 20 seeds are sown per one planting unit, and the size of one planting unit of a commonly used nursery mat is about 23 mm square. Based on these factors, we have experimentally studied the specifications of the optimum pressure-sensitive adhesive sheet for sowing and raising seedlings for green onions, and as a result, we have reached the conclusion of the above specifications.

That is, when the adhesive application area per point adhesive is 0.5 to 1.2 mm ² , the average number of seeds loaded on each adhesive dot of the above-mentioned onion seeds is about 2 By setting the number of dots of adhesive applied per planting unit to eight, the average number of seeds mounted per planting unit can be about 16 seeds. It was also found that the gap between the adjacent point-like adhesives of adjacent planting units was set to 8 to 12 mm, so that a gap can be provided in the center and the product has a good sense of volume. did. In addition, as a result of actual cultivation experiments, when such adhesive coating area and number were used, not only the growth rate of the green onion seedlings and the seedling alignment but also the thickness of the stems after harvest and the uniformity of stem length were obtained. It turned out that it is superior to etc.

Here, the reason why the void for one adhesive dot is provided in the central portion in the arrangement of the dot adhesive is as follows. That is, if the dot adhesive is arranged in a grid of 3 rows and 3 columns, for example, the dot adhesive placed in the center is surrounded by other dot adhesives, and therefore it is installed here. The germinated seedlings are not only disadvantageous to the surrounding seedlings in terms of environmental conditions such as light and temperature during their growth, but also their existence adversely affects the growth of the surrounding seedlings. Also becomes. Therefore, compared to the case where there is no seedling in the central part, the growth will be delayed overall. Also, as described above, it is difficult to perform lower leaf removal work on green onions grown from seeds mounted on the adhesive in the central part.

As described above, in the arrangement of the point adhesive, by providing the void in the central portion, it is possible to improve the quality of the harvested crop and the work efficiency during cultivation.

Embodiment 1 FIGS. 1 and 2 are partially enlarged views showing the constitution of an embodiment of an adhesive sheet for seeding and raising seedlings of onion of the present invention, FIG. 1 is a perspective view, and FIG. 2 is a top view. 8 shows that each point-shaped pressure-sensitive adhesive 2 is applied to each fixed unit of the strip-shaped support 1. Here, the diameter d of the point-like adhesive 2 is about 0.9 mm (area about 0.6 mm ² ), and the eight point-like adhesives are coated so as to be located at the peripheral points on the 3 × 3 grid points. I worked. The distance L ₁ between adjacent point-like adhesives in the planting unit was 5.5 mm, and the distance L ₂ between adjacent point-like adhesives between adjacent planting units was 12 mm.

[0014] Compared to the case where the onion was hydroponically cultivated using the above-mentioned pressure-sensitive adhesive sheet for seeding and raising seedlings, and the onion seeds were manually sown, thinning during cultivation and lowering after harvesting were performed. We were able to reduce the amount of work such as leaf removal to about 1/3. Also, with regard to the harvested green onions, it was possible to harvest high quality ones with relatively little variation among individual growth bodies.
