Problems solved by technology

At present, there is a fumigation method to fumigate rice seeds in a steamer. The disadvantage of this disinfection method is that it is easy to steam the seeds at the bottom of the steamer, causing the seeds to lose their activity.

Embodiment 1

[0015] Select Y Liangyou No. 6 as the experimental variety, first wash the rice seeds with tap water for 0.2 hours, then pre-soak the washed rice seeds with clean water for 8 hours; pick up the pre-soaked rice seeds Dry the water; then immerse the dried rice seeds in a 300-fold dilution of 40% trichloroisocyanuric acid for disinfection, and the soaking time is 9 hours; finally rinse with tap water for 2 hours and rinse once. Variety Y Liangyou No. 6 has a pollution rate of 0.6%, a germination rate of 97%, and a strong germination potential.

Embodiment 2

[0017] Select Y Liangyou No. 6 as the experimental variety, first wash the rice seeds with tap water for 0.5 hours, then pre-soak the washed rice seeds with clean water for 10 hours; pick up the pre-soaked rice seeds Dry the water; then immerse the dried rice seeds in 40% trichloroisocyanuric acid 500-fold dilution for disinfection, the soaking time is 11 hours; finally rinse with tap water for 3 hours and rinse twice, the experiment Variety Y Liangyou No. 6 has a pollution rate of 0.5%, a germination rate of 99%, and a strong germination potential.

Embodiment 3

[0019] Select Y Liangyou No. 6 as the experimental variety, first wash the rice seeds with tap water for 0.1 hour, then pre-soak the washed rice seeds with clean water for 4 hours; pick up the rice seeds after pre-soaking and water absorption Dry the water; then immerse the dried rice seeds in a 100-fold dilution of 40% trichloroisocyanuric acid for disinfection, and the soaking time is 5 hours; finally rinse with tap water for 1 hour and rinse once. Variety Y Liangyou No. 6 had a pollution rate of 3.4%, a germination rate of 87%, and a mediocre germination potential.

[0020] By comparing Example 1, Example 2 and Example 3, it can be seen that the rice seeds of Example 1 and Example 2 can achieve better disinfection effect, and the pollution rate is 0.6% and 0.5% respectively, but the rice seeds of Example 3 Seed pollution rate is 3.4%; The germination rate of embodiment one and embodiment two rice seeds is respectively 97%, 99%, but embodiment three rice seed germination rat...

Abstract

The invention provides a disinfection method of rice seeds and particularly relates to the technical field of agriculture. The disinfection method comprises the following steps: (S1) washing the rice seeds for 0.2-0.5 hour by using running water, and preimpregnating the washed rice seeds to absorb water by using clean water; (S2) fishing out the rice seeds preimpregnated and water-absorbed to dry water; (S3) impregnating the dried rice seeds into diluent with 300-500 times of 40% trichloroisocyanuric acid to carry out disinfection, wherein the soaking time is 9-11 hours; and (S4) finally cleaning with the running water. The disinfection method provided by the invention has the advantages that the removal is easy, no residual toxicity is generated, the damage to the seeds is less, and the pesticide applying times and the pesticide use amount for the rice at the growth period can be effectively reduced, so that not only is the production cost reduced, but also the pollution to the environment is reduced and the like.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a rice seed disinfection method. Background technique [0002] Rice is one of the most important grain crops in my country's agricultural production, and rice production accounts for 43% of my country's total grain output. In the past few decades, genetic breeders and agricultural experts in my country have made great contributions to improving the yield of rice. With the growth of population and the continuous improvement of people's living standards, and in order to meet the needs of commodity grain export trade, it is necessary to produce more grains that are more suitable for people's tastes. Therefore, cultivating new rice varieties with higher yield and better edible quality is still the goal pursued by genetic breeders. Rice seeds are very easy to carry various pathogens during storage. At present, it is an indispensable processing technology for modern agriculture t...
