Problems solved by technology

[0003] At present, the application of pelletized coating technology has been relatively common, but it is still difficult to see rice-coated pellets on the market, and the coating of ordinary pellets has a small drug load and a short duration of action. self-degradation, and various problems often appear in the preparation process of pelletized seeds, such as the pill coating of pellets is easy to crack in the natural state, the hardness of pelleted seeds is poor, and the time of cracking in water is too long Long, generally more than 60 seconds, which is not good for germination and emergence

Embodiment 1

[0031] A kind of preparation of paddy rice pelletized seed, comprises the steps:

[0032] A. Select rice seeds: purify the rice seeds to be pelletized to remove sand and sundries in the seeds;

[0033] B. Put the seeds into the coating container, spray the seeds with a liquid composition containing a binder (calcium peroxide: carboxymethyl cellulose 1:1) while the container is rotating, and then put in a coating containing silicon dioxide and bentonite a coating composition to bind the seed;

[0034] C. Pour the granulated seeds obtained in step B into the coating container, continue to repeat step B, carry out the above operation every 40 seconds, repeat three times, and obtain pelletized seeds;

[0035] D. Suspending and drying the pelleted seeds obtained in step C to obtain uniform pelleted seeds.

Embodiment 2

[0037] A kind of preparation of paddy rice pelletized seed, comprises the steps:

[0038] A. Select rice seeds: purify the rice seeds to be pelletized to remove sand and sundries in the seeds;

[0039] B. Put the seeds into the coating container, spray the seeds with a liquid composition containing a binder (calcium peroxide: polyvinyl alcohol weight ratio 1:3) while the container is rotating, and then put in a coating containing silicon dioxide and bentonite a coating composition to bind the seed;

[0040] C. Pour the granulated seeds obtained in step B into the coating container, continue to repeat step B, carry out the above operation every 60 seconds, repeat three times, and obtain pelletized seeds;

[0041] D. Suspending and drying the pelleted seeds obtained in step C to obtain uniform pelleted seeds.

Embodiment 3

[0043] A kind of preparation of paddy rice pelletized seed, comprises the steps:

[0044] A. Select rice seeds: purify the rice seeds to be pelletized to remove sand and sundries in the seeds;

[0045] B. Put the seeds into the coating container, spray the seeds with a liquid composition containing a binder (calcium peroxide: cellulose weight ratio 1:5) while the container is rotating, and then drop into the coating containing silicon dioxide and bentonite. a coating composition to bind the seed;

[0046] C. Pour the granulated seeds obtained in step B into the coating container, continue to repeat step B, carry out the above operation every 50 seconds, repeat three times, and obtain pelletized seeds;

[0047] D. Suspending and drying the pelleted seeds obtained in step C to obtain uniform pelleted seeds.

Abstract

The present invention relates to pelletized seeds for rice direct sowing and a pelletizing method of the pelletized seeds. The pelletized seeds comprise rice seeds, a binder and a coating composition,wherein when the binder is formed by compounding of calcium peroxide and other binders in the ratio of 1:1 to 1:5, the obtained pelletized seeds have the more excellent strength and germination rate.The preparation method of the pelletized seeds comprises the following steps: A, selecting the rice seeds: performing purifying treatment on the rice seeds to be pelletized to remove sand and impurity substances in the seeds; B, putting the seeds into a coating container, spraying a liquid composition containing the binder to the seeds while the container is rotated, putting the coating composition, and enabling the coating composition to be combined with the seeds; C, pouring the granulation seeds obtained in the step B into a coating container, and continuing repeating the step B, wherein the above operation is performed every 40-60s, and repeating is performed for three times, so as to obtain pelletized seeds; and D, performing suspension drying on the pelletized seeds obtained in thestep C to obtain the uniform pelletized seeds. The pelletized seeds provided by the present invention have a simple preparation process and are suitable for actual production.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and specifically relates to a pelletized seed suitable for direct-seeding rice and a pelletized method thereof. Background technique [0002] Pellet coating is a new agricultural technology that has been put into use after film coating. Due to the difficulty of manual and mechanical sowing of small and particulate seeds, especially direct seeding causes serious seed waste, seed pellet coating This problem can be solved; secondly, because small seeds, especially particulate seeds, are small and have poor tolerance, the use of fungicides or fertilizers for film coating can easily cause phytotoxicity, and pelletized seed coating is due to the The shielding effect of the medicament slows down the phytotoxicity caused by the medicament to the seeds and seedlings; in addition, chemical substances that promote the growth of roots and seedlings can be added to the seed pellet coating to imp...
