Abstract
The invention relates to a plant resistance agent, in particular to a leaf surface preparation for rice disease-resistant and yield increase, which belongs to the field of plant nutrition physiology. The preparation consists of a proline, a methionine, phenylalanine and other basic components as well as a trace element, an additive and water. The preparation is directly added through the leaf surface, with the resistance effect on disease, such as rice blast, etc.; the key point is that the methionine is transmitted into ethylene, which activates an oxidase and lyase system in vivo, promotes the phenylalanine and the proline to synthesize a lignin and strengthens host cell wall; cell allergic necrosis reaction is formed; a plant protection is generated, such as a flavonoid and a phenolic acid, etc. The invention can be sprayed in breach period and full heading period of the rice, and with test, control effect of rice blast is more than 75 percent, which is similar to that of a tricyclazole, moreover, disease index of the invention is lower than that of the tricyclazole. Compared with the rice field sprayed with the tricyclazole, the rice field sprayed with the invention has yield increase of 12 kg.
Description
Technical field: [0001] The invention relates to plant stress resistance, in particular to a foliage preparation for disease resistance and yield increase of rice, belonging to the field of plant nutrition and physiology. Background technique [0002] When plants grow and develop in a natural environment, it is inevitable that they often encounter unfavorable factors such as pathogenic microorganisms, drought, flood, and low temperature. These unfavorable factors are collectively referred to as adversity. During tens of thousands of years of evolution, plants will also adapt to the environment and produce corresponding self-protection mechanisms through mutation to resist the impact of various adversities. For example, after plants are stimulated by pathogenic factors, they actively regulate the activities of various related enzymes in the body, causing a series of changes in plant morphology, physiology and biochemistry, and forming various responses related to disease resi...
