Rice seed disinfection method
The judgment of rice seed quality is a large part of agriculture. It includes the determination of the 1000-grain weight of rice seeds, the determination of the purity and cleanliness of rice seeds, and the determination of the moisture content of rice seeds. In order to determine the 1000-grain weight of a rice seed, it is necessary to first count 1000 seeds using a counting instrument, an automatic photoelectric counting number, and then weigh the 1000 seeds using a balance. The purity of rice seeds can be selected using instruments such as seed clarity, wind-selection, and the like. However, the focus of this article is not to identify the quality of the seeds, but rather how to disinfect the seeds.
1. Immerse the seeds with 50% carbendazim, 50% thiophanate-methyl or 50% thiram 500 times for 48 hours (200-70 kg can be immersed in 100 kg of water and 200 kg of liquid.) Then remove the germination, sowing, the effect of the prevention of bastard disease is better, but also can cure rice blast, leaf spot disease, seedling blight.
2. Soak the seed with 200 times liquid with 40% strong chlorine. Seed soaked with water for 12 hours, and then soaked in liquid for 12 hours, then rinse with water, remove germination, sowing, can prevent bacterial streak, bacterial blight and so on.
3. Use 0.2% copper sulfate solution to soak seeds for 48 hours, then remove the germination and sowing to prevent bastard disease and rice smut.
4. Soak the seed with 500% solution of 40% formalin. The seeds were soaked in fresh water for 1-2 days (in order to absorb enough water but not exposed to whiteness), they were air-dried after being taken out and soaked in the liquid for 48 hours. The seeds were then rinsed with clean water and germinated and sowed. It can prevent rice blast, bastard disease, leaf spot disease, smut, and rice smut.

7, with 10% soaking spirit 500 times soaking seeds for 48-60 hours, can prevent bastard disease, and prevent dry aphid disease, rice blast disease.
8, take the appropriate amount of 70% hymexazol (soil bacteria elimination), before sowing by dry rice seed amount of 0.4-0.7% mixed with rice, dry mix, wet mix can prevent seedling blight and so on.
9, soaking seeds with 0.1-0.2% potassium permanganate solution for 24 hours, can prevent a variety of fungal, bacterial species transmission diseases.
