Abstract

The invention discloses a compound preparation capable of improving the virus resistance of plants, and application of the compound preparation. The compound preparation is characterized by being prepared by compounding beta-amino-butyric acid and ningnanmycin or amino-oligosaccharin; when the compound preparation is applied, seeds are soaked into the compound preparation for 6 hours, and / or foliage spray is carried out on the plants with 5-6 leaf stage by the compound preparation. After the compound preparation is used, the pesticide effects of all the raw materials are exerted to a great extent, so that the activity of the drug is remarkably improved; the compound preparation is capable of remarkably improving the virus resistance of the plants in a big field and improving the production value and quality of the plants.

Description

technical field [0001] The invention relates to a compound preparation for improving plant resistance to viral diseases, belonging to the technical field of bioengineering. Background technique [0002] After the plant virus infects the host, due to the strict parasitic nature of the virus and the lack of a perfect immune system in the plant, it is very difficult to prevent and treat viral diseases. Therefore, plant virus disease is also called "plant cancer". According to statistics, the economic losses caused by plant virus diseases to plants reach more than 550 million US dollars every year. After the virus infects the host, it not only competes with the host for the nutrients necessary for growth, but also destroys the nutrient transport of the plant, changes some metabolic balance of the host plant, inhibits the photosynthesis of the plant, makes the plant difficult to grow, and produces deformity Symptoms such as yellowing and yellowing can seriously cause the death ...
