Fertilization method for reducing bacterial wilt and bacterial leaf spot of pepper and improving drought resistance of pepper

Abstract

The invention relates to a fertilization method for reducing the bacterial wilt and bacterial leaf spot of pepper and improving the drought resistance of pepper. According to the method, in the wholegrowth period of pepper, 20-30 kg of pure nitrogen, 5-10 kg of pure phosphorus and 20-40 kg of pure potassium are applied per mu; before pepper transplanting, 9-14 kg of pure nitrogen, 2.5-5 kg of pure phosphorus and 13-27 kg of pure potassium are applied per mu as a base fertilizer in combination with soil preparation; after pepper planting, various fertilizers are applied at different times in different growth periods, and meanwhile a pyrroloquinoline quinone solution with the mass concentration of 100-300 nmol / L is applied, wherein the application amount each time is 15 L / mu, and the pyrroloquinoline quinone solution is applied 3 times in total. The method has the advantages that different fertilizers are selected according to different growth periods of pepper, different kinds of potash fertilizers are selected for cooperative application, the pyrroloquinoline quinone solution is also applied, the adaptability of pepper to bacterial wilt, bacterial leaf spot and drought environmentcan be improved, the use quantity of pesticides is reduced, and the method has great economic value and ecological value.

Description

technical field [0001] The invention relates to an application method of crop fertilizer, in particular to a fertilization method for reducing capsicum bacterial wilt and bacterial leaf spot and improving capsicum drought resistance. Background technique [0002] Capsicum is an important solanaceous vegetable with rich nutrition. Its vitamin C content is 5 times that of tomato, 20 times that of eggplant, and the content of carotene is 7-15 times that of tomato and 20-35 times that of eggplant. Pepper is one of the vegetable crops with the largest planting area in my country. In 1997, the total output of pepper in my country ranked first in the world, with an annual output of 28 million tons, accounting for about 46% of the world's pepper production. The planting area and economic value of pepper have surpassed cabbage to become the first A large vegetable crop. [0003] Capsicum bacterial wilt and capsicum bacterial leaf spot are two important diseases in the planting proces...

Problems solved by technology

[0003] Pepper bacterial wilt and pepper bacterial leaf spot are two important diseases in the process of pepper planting, which cause death or yield reduction of pepper after the onset, causing great losses to agricultural production

At present, most of the above two diseases are controlled by using pesticides or breeding resistant varieties, which can reduce the incidence of peppers and reduce losses to a certain extent, but the residual pesticides threaten human health and pollute the soil, and the resistance of resistant varieties is easy. lost

At the same time, the important growth period of hot pepper in summer is high temperature and less rain, and if the pepper is not irrigated in time, it will easily cause economic losses.
