Cultivation method for increasing capacity of tomatoes for resisting leaf mold

Abstract

The invention discloses a cultivation method for increasing capacity of tomatoes for resisting leaf mold. Through combination of resistant inducers including heteroauxin, ethephon and elancolan, withmelatonin, the leaf mold of the tomatoes can be notably restrained, the resistance of the tomatoes can be increased, and the effects of being safe, environmentally-friendly and pollution-free can be achieved; besides, the resistant inducers, the melatonin and NaHS are subjected to combination treatment, so that the incidence rate of the leaf mold of the tomatoes is greatly reduced; the resistant inducers can remove influence of environmental stress on plants, the stress resistance of the plants can be effectively promoted, the photosynthetic rate of the plants is guaranteed, and the growth oftomato plants and accumulation of photosynthesis products are effectively promoted; and more importantly, the resistant inducers are non-toxic and pollution-free, environmental pollution and drug resistance of thalli caused by massive application of chemical agents are avoided, NaHS is disintegrated to release H2S gas and is also easy to degrade and pollution-free, and the cultivation method is suitable for extensive promotion and use.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a cultivation method for improving tomato leaf mold resistance. Background technique [0002] Tomato leaf mold is an epidemic disease caused by fungi of the genus Fucospora, especially in protected areas. The special humid microclimate environment is more likely to lead to the rapid spread of pathogenic bacteria, which seriously affects tomato production. Tomato leaf mold mainly harms the middle and lower leaves of seedlings, and in severe cases, it also infects stems and fruits, which reduces the quality and yield of fruits, and causes serious economic losses. The disease often spreads from the lower leaves to the upper new leaves gradually. When the disease is severe, the mold layer spreads all over the back of the leaves, the leaves curl, and the leaves of the whole plant shrivel and dry and fall off early. [0003] Tomato leaf mold is mainly controlled by chemical steril...

AI Technical Summary

Problems solved by technology

[0003] Tomato leaf mold is mainly controlled by chemical sterilization in production. At present, the commonly used chemical pesticides for the prevention and treatment of tomato leaf mold mainly include thiophanate-methyl, azoxystrobin, thiophanate-methyl, flusilazole or captan, etc. , but long-term use of chemical pesticides in large quantities, pathogenic bacteria are likely to develop resistance, resulting in reduced control effects, and at the same time cause agricultural products and environmental pollution, as well as new diseases or secondary diseases. The most important thing is that it is difficult to improve from the root Tomato resistance leads to leaf mold resistance
