Problems solved by technology

And in said open patent, even if it is 40% of the seed weight (5kg) used, the amount of described silicic acid also has only 2kg, converts into water-soluble silicic acid within 1~2 months, and the silicic acid effect presents time Too short, the amount of converted water-soluble silicic acid is also very small

Embodiment 1

[0092] (1) Rice seeds: using an awner to remove awns from rice seeds, dry them, and prepare them for storage.

[0093] (2) Manufacture of binder: Put the powdered humic acid into 80°C ultrapure water, dissolve it by stirring, and leave it for 10 days to fully ferment it. A carboxymethylchitosan (carboxymethylchitosan) solution was mixed with the humic acid solution after fermentation, stirred, and then fermented while stirring for 2 days to prepare a mixed solution of humic acid and chitosan. A certain amount of ultrapure water was added to the mixed solution produced above, stirred, and filtered to remove air bubbles. Thereafter, liquid silicic acid, sodium alginate (sodium alginate) and water-soluble molybdenum were mixed with the filtered mixed solution while stirring at a speed of 15 RPM to manufacture a binder. The content of each component is, relative to the total weight of the binder, containing 10% by weight of liquid silicic acid, 0.5% by weight of chitosan, 8% by w...

Embodiment 2

[0100] It was manufactured in the same manner as in Example 1, except that soybeans were used instead of rice seeds to form a coating layer.

experiment example 2

[0108] Experimental example 2: Investigation of the establishment rate of coated rice seedlings related to soaking time

[0109] The rice seeds of Example 1 and Comparative Example 1 produced as described above were prepared and cultivated in the glasshouse of Gyeonggi-do Institute of Agricultural Technology. In each test garden, 10 coated rice seeds were sown on the left side, and 10 common rice seeds were sown on the right side, and 6 gardens were prepared in total. The 6 gardens were soaked in water for 1 day, 3 days, 6 days, 9 days, 12 days, and 14 days respectively, and were cultivated for 24 days under the condition of 20°C to 25°C to investigate the establishment rate of seedlings and record them in the table below 2.

[0110] 【Table 2】

[0111] As shown in Table 2 above, compared with the common rice seeds of Comparative Example 1, the coated rice seeds of the present invention have significantly better seedling establishment rate.

Abstract

The present invention relates to a coated seed manufacturing method and a coated seed prepared by the coated seed manufacturing method. In particular, the coated seed manufacturing method comprises the step of mixing a binder, an auxiliary binder and inorganic powder into seeds to form a coating layer on seed surface; the binder comprises liquid silicic acid, chitosan, humic acid, molybdenum, sodium alginate and water, the auxiliary binder comprises one or more of gypsum powder, starch powder and flour, the inorganic powder includes zeolite, bentonite, medical stone, langbeinite and biotite. The present invention also provides the coated seed which is prepared by the coated seed manufacturing method.

Description

technical field [0001] The present invention relates to a method for producing coated seeds and coated seeds produced thereby. Background technique [0002] Generally, rice cultivation adopts the method of cultivating seedlings and planting them in fields. Rice cultivation requires considerable labor from sowing seedlings to planting rice fields. However, recently the number of rural populations has been decreasing, coupled with the aging population, the labor force has been decreasing in both quantity and quality, and solutions are urgently needed. [0003] Silicon (Si) exists in abundance on the surface of the earth, and although it is not usually an essential element for plants, it is important in the composition of plants. It is known that silicon absorbed from the roots of plants moves together with the transpiration stream and is stored in the cell walls, intercellular spaces and outer layers of cells (Marschner et al., 1990). This silicon element is stored in the r...
