Embodiment 1

[0011] Weigh 0.01g of 60% cotton long, 0.5g of 96% albutan, and 5g of 25% cyprostrobin into a container, add 4000g of water, stir evenly, add 3 kg of rice seeds, soak for 24 hours, and the soaking temperature is 20°C. Seeds are soaked for a sufficient time to germinate and sow in white. The seedling raising method is dry seedling raising. After the seedlings are 20 days old, they are transplanted into the field. After the rice is harvested, 200 rice grains are randomly selected, crushed and shelled, and the rice grains with black spots are counted.

Embodiment 2

[0013] Weigh 0.1g of 60% Cottonon, 2g of 96% Bataan, and 15g of 25% Cyclostrobin into a container, add 8000g of water, stir evenly, add 3kg of rice seeds, soak for 48h, soaking temperature is 28°C, soak the seeds After a sufficient period of time, the seedlings will be sprouted until they are sown in white. The seedling raising method is dry seedling raising. After the seedlings are 20 days old, they are transplanted into the field. After the rice is harvested, 200 grains of rice are randomly selected, crushed and shelled, and the rice grains with black spots are counted.

Embodiment 3

[0015] Weigh 0.05g of 60% Cottonon, 1.25g of 96% Padang, and 10g of 25% Cyclostrobin into a container, add 6000g of water, stir evenly, add 3 kg of rice seeds, soak for 36 hours, and the soaking temperature is 25°C. Seeds are soaked for a sufficient time to germinate and sow in white. The seedling raising method is dry seedling raising. After the seedlings are 20 days old, they are transplanted into the field. After the rice is harvested, 200 rice grains are randomly selected, crushed and shelled, and the rice grains with black spots are counted.

Abstract

The invention discloses a composition, which comprises the following components: 0.01-0.1g of 60% daniron, 0.5-2g of 96% batan, 5-15g of 25% cyprostrobin, and 4000-8000g of water. The invention also discloses the application of the composition in controlling the production of rice black rice. The invention also discloses a method for controlling the generation of rice black rice through seed soaking. The invention kills and controls various pathogenic bacteria in the rice seeds through the technical measure of soaking the rice seeds with chemicals before sowing, so as to achieve the purpose of preventing and controlling the formation of black-spotted rice. The imitation of the control black spot rice of the present invention has reached 100%.

Description

technical field [0001] The invention relates to a method for controlling the formation of black-spotted rice, in particular to a method for controlling the generation of black-spotted rice by soaking seeds. Background technique [0002] Black-spotted rice refers to diseases that seriously affect rice quality due to black spots and cracks on rice grains due to the harm of pathogenic microorganisms or stinkbugs during the growth of rice. The generation of black spot rice has a strong impact on the appearance and quality and quality of rice. According to a preliminary survey, black spot rice occurs in all rice areas of the country, especially in southern rice areas. It is very common in early and late rice in Zhejiang Province, and the incidence rate of serious grains is over 90%. For farmers, the rice was rejected by the grain storage department, and it was difficult to sell the grain, which affected the steady growth of farmers' income. Contents of the invention [0003] ...
