Problems solved by technology

Especially when wheat is broadcast directly in the paddy fields in autumn, the wheat seeds fall on a thick layer of bryophytes and cannot directly contact the soil, making it difficult for the wheat roots to penetrate into the soil. Wheat seedlings were frostbitten or frozen to death because they were thin and not resistant to cold, causing serious losses
Ordinary chemical herbicides cannot remove sedge algae in paddy fields very well. Manual removal is labor-intensive and the effect is not good.

Embodiment 1

[0024] Weigh 100g of copper sulfate, 35% of moss algae net [propazone, 4,6-diisopropylamino-2-methylthio-1,3,5-triazine]) 80g, 50% trichloroisocyanurate Acid 40g, dry sand 3kg, water 1kg. Copper sulfate is pulverized, dry sand and water are evenly mixed to make wet sand. Then mix copper sulfate, moss algae net, trichloroisocyanuric acid and wet sand and stir evenly. Sprinkle evenly into the rice field at 5 pm on a sunny day, and use it again after a week. All can be eradicated.

Embodiment 2

[0026] Weigh 150g of copper sulfate, 35% of moss algae net [propazone, 4,6-diisopropylamino-2-methylthio-1,3,5-triazine]) 100g, 50% trichloroisocyanurate Acid 50g, dry sand 4kg, water 1.25kg. Copper sulfate is pulverized, dry sand and water are evenly mixed to make wet sand. Then mix copper sulfate, moss algae net, trichloroisocyanuric acid and wet sand and stir evenly. Sprinkle evenly into the rice field at 6 pm on a sunny day, and use it again after a week. All can be eradicated.

Abstract

The invention discloses a method for removing moss and algae in paddy fields, belonging to the technical field of agricultural crop control. The method is characterized by preparing a medical solution and sprinkling the medical solution in the paddy fields, wherein the prepared medical solution comprises copper sulfate, 35 % moss and algae remover, 50 % trichloroisocyanuric acid, dry sand, and water. According to the invention, the usage method is simple and convenient, by utilizing different medicinal mechanisms of copper sulfate, moss and algae remover, and trichloroisocyanuric acid on the moss and algae in the paddy fields, intractable moss and algae in the paddy fields are effectively eliminated, pollution to the paddy and environment is not caused, and the method is safe and has no side effect to aquaculture animal.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural crop prevention and control, in particular to a method for eliminating swollen algae in paddy fields. Background technique: [0002] In the planted rice fields, during the water pipe period, a lot of scorpion algae will grow under the water surface. Borex algae include filamentous green algae such as Spirogyra, Bistarella, Transplatina, and Hydronetella. The bryophytes are all over the paddy fields, seriously affecting the development of the rice root system and the absorption of nutrients. The bryophytes reproduce and grow fast, and absorb a large amount of rice field fertilizer, and more than 80% of the fertilizers are absorbed by the bryophytes. Loss of fertilizer causes malnutrition in rice growth. Carrageensis has tenacious vitality. As long as the paddy field is flooded, the carapaceous algae will reproduce and grow quickly, and spread to the whole field, making it difficult to erad...
