A method of treating rice seeds and seedlings to improve rice resistance

Abstract

The invention belongs to the technical field of agriculture cultivation and specifically relates to a method of processing rice seeds and rice shoots for improving the paddy rice resistance performances. By simulating drought and low temperature to respectively process rice seeds and rice shoots, the ability of rice plants to resist diseases and insects is increased; at the filling stage and the milk-ripe stage of the rice, leaf blast rate of the rice plants that are processed by simulating drought and low temperature is respectively reduced to 22.1 percent and 28.7 percent in comparison with the rice plants that not processed; and at the same time, at the filling stage and the milk-ripe stage of the rice, the number of brown planthopper of the rice plants that are processed by simulating drought and low temperature is respectively reduced to 19.4 percent and 24.1 percent in comparison with the rice plants that not processed. After the rice seeds are processed by simulating drought and low temperature, the ability of the rice to resistance leaf blast and planthopper is significantly strengthened while significantly increasing the rice production to 9.2 percent; and the use of pesticide during the production process of the rice is reduced, thus the rice is ensured to be produced with safety, high quality and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a method for treating rice seeds and seedlings to improve rice resistance. Background technique [0002] Rice (Oryza sativa) is an important food crop for humans, and about 50% of the world's population uses rice as a staple food. About 95% of the population in Asia takes rice as a staple food. In 2013, my country's rice accounted for 40% of food crops, ranking first. At the same time, my country is the world's largest rice producer and rice consumer. Therefore, reducing rice pests and diseases is of great significance to increasing rice yield and ensuring my country's food security. [0003] With the increase of rice planting area year by year, the problem of rice plant diseases and insect pests is becoming more and more serious, which has a serious impact on rice production and huge economic losses. In the process of rice production, rice pests and ...

Problems solved by technology

[0006] In order to overcome the shortcomings and deficiencies of the prior art, the primary purpose of the present invention is to provide a method for treating rice seeds and seedlings to improve rice resistance. The method does not need to add chemicals, has no environmental pollution problems, and is suitable for modernization, scale, and green Pollution-free rice production. At the same time, this method can effectively reduce the use of pesticides in the rice production process, effectively reduce the occurrence of rice diseases and insect pests, and improve the quality and yield of rice.
