A method for treating dead rice seedlings

Abstract

The invention discloses a method for treating rice red blight. The method comprises the following steps that firstly, 10 grams of 40% chlorine worm and thiamethoxam oxazine water dispersible granule and 16 milliliters of 0.01% brassin are mixed to prepare a solution, and water is added into the solution until the volume of the total solution reaches to 1000 milliliters; secondly, water in a rice field is drained out; thirdly, the solution prepared in the first step is sprayed to rice seedlings; fourthly, shallow water is poured into the rice field after two to three days of spraying, and 5-7 kilograms of urea and 5-8 kilograms of 45% compound fertilizer are scattered to the rice field; fifthly, after seven to ten days of fertilizer applying, 8 grams of 40% chlorine worm and thiamethoxam oxazine water dispersible granule and 8 milliliters 0.01% brassin are mixed to prepare a solution, water is added into the solution until the volume of the total solution reaches to 1000 milliliters, and the solution is sprayed to all the rice seedlings in the rice field. The method can overcome the defects in the prior art, the rice red blight can be treated without the side effect, and the rice yield is improved.

Description

technical field [0001] The invention belongs to the field of crop disease prevention and control, and in particular relates to a method for treating stiff rice seedlings. Background technique [0002] Rice is the largest grain production crop in China. my country is also the largest rice producing country in the world, accounting for 35% of the world's output. Nearly half of the world's population takes rice as a staple food. Therefore, rice production plays an important role in safeguarding people's survival and society. plays a very important role in the stability of the It is particularly important to prevent and control diseases and insect pests in all aspects of rice production, and rice seedlings are one of them, which seriously affects the yield of rice. [0003] The method of curing rice seedlings is generally based on prevention. There are many ways to cure them, but the effect is not very satisfactory, especially for rice planted in hilly areas. Farmers often use l...

Problems solved by technology

[0003] The method of curing rice seedlings is generally based on prevention. There are many curing methods, but the effect is not ideal, especially for rice planted in hilly areas. Farmers often use light and simplified planting techniques, and rice seedlings often occur in large areas.

On the other hand, due to the underdeveloped economy in remote mountainous areas, no reasonable and effective control methods have been adopted, and it is difficult to cure the stiff seedlings of rice. Even if it is cured, it is difficult to achieve the original yield.
