Zizyphus maurtiana planting method

Abstract

The invention provides a zizyphus maurtiana planting method and relates to the field of planting of zizyphus maurtiana. The zizyphus maurtiana planting method comprises the steps of field planting and water-fertilizer management, and further comprises the following step: spraying a certain amount of a microbicide in each growth period of zizyphus maurtiana. The microbicide comprises the following components: a bacillus subtilis agent, a trichoderma harzianum agent, a photosynthetic bacterium agent, a yeast agent, a bacillus thuringiensis agent and an enzyme enhancer preparation, wherein the enzyme enhancer preparation comprises such components as chitinase, glucanase and protease. By adoption of the zizyphus maurtiana planting method provided by the invention, the occurrence and spread of diseases and insect pests can be effectively controlled, the number of fruits with disease spots and the fruit dropping rate can be reduced; the quality and the yield of the zizyphus maurtiana can be improved; and the pollution-free planting effect can be achieved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of jujube, in particular to a method for planting jujube. [0003] 【Background technique】 [0004] Daqing jujube, also known as Indian jujube, belongs to the genus Jujube in the family Rhamnaceae. It is an evergreen small tree native to Southeast Asia, Africa and Oceania. It was introduced from India and Thailand in the middle of the 20th century in Taiwan. After long-term selection and cultivation, Many excellent varieties have been introduced, and they were successfully introduced to Dongguan, Guangdong by Taiwanese businessmen in the late 1990s. Due to their characteristics of planting results in the same year, high yield, good quality and rich nutrition, they have developed rapidly in southern provinces of my country in recent years. However, due to the fast growth of jujube, the problem of pests and diseases has become increasingly prominent, which has become a limiting factor for the improvement...

AI Technical Summary

Problems solved by technology

The fungus mainly harms its branches, leaves, flowers and fruits, causing lesions, discoloration, and roughness on the peel, which loses commercial value. At the same time, fruits severely infected by the fungus may even fall in large numbers, resulting in a decrease in yield

At present, the prevention and control of fungal diseases of jujube is mainly based on the use of chemical pesticides and mineral-sourced pesticides, but the diseases have been effectively controlled by chemical pesticides such as triadimefon, myclobutanil, thiophanate-methyl, carbendazim and polyresistant Toxins, etc. produce different degrees of drug resistance, which leads to an increase in the amount of drugs used, and the control effect is not obvious. However, the control concentration of lime sulfur mixture is close to the concentration of phytotoxicity on jujube, and a little carelessness of fruit trees will cause pesticides Therefore, the prevention and treatment of fungal diseases of jujube has become an urgent problem to be solved

[0006] Studies have shown that active substances such as subtilisin, polymyxin, nystatin and gramicidin produced during the growth of Bacillus subtilis have obvious effects on pathogenic bacteria and opportunistic pathogens of endogenous infection. Inhibitory effect, can prevent and control crop leaf diseases, including anthracnose, target spot, downy mildew and powdery mildew, etc., and Trichoderma harzianum and its metabolites can inhibit the infection of pathogenic fungi on plants, especially The control effect on Pythium, Fusarium, Anthracnose and Botrytis is better, but the effect of these fungicides alone is not strong
