Planting method for preventing mango black spot disease

Abstract

The invention provides a planting method for preventing mango black spot disease, comprising soil treatment, seedling selection planting and planting management. The soil structure is improved by using a soil conditioner and the nutrient absorption is promoted; during fertilization, a base fertilizer, a root fertilizer and a foliar fertilizer are applied together according to different periods toimprove tree resistance; timely pruning ensures plenty of nutrients in the fruit. Soil structure is improved, so as to provide sufficient nutrients, improving tree resistance, fully increasing the mango fruit set rate and effectively reducing the incidence of black spot diseases.

Description

technical field [0001] The invention relates to the technical field of fruit planting, in particular to a planting method for preventing mango black spot disease. Background technique [0002] Mango is also known as lemon fruit, mango fruit, boring fruit, honey hope, hope fruit, ampolo fruit, Anacardiaceae. my country's mango planting areas mainly include Hainan, Guangxi, Yunnan, and Sichuan. The main mango producing areas in Guangxi are concentrated in Baise, Qinzhou, Nanning, Yulin and the southern part of Liuzhou. Mango has become an important economic crop in Guangxi, and the mango planting area is also increasing. [0003] Mango black spot is one of the main diseases in mango growing areas. Angular spot is also called bacterial black spot or canker. Mainly damage shoots, leaves and fruits. Small black spots the size of needleheads appear on the infected leaves of unturned green shoots, and then expand into small raised black spots with yellow halos around them. The...

AI Technical Summary

Problems solved by technology

2. Varieties with poor disease resistance

3. There are bacteria, the seedlings are diseased or the garden is not cleared thoroughly in winter, the germs survive the winter with the diseased residues, and infect the plants in spring

5. Unreasonable use of fertilizers, too much nitrogen and phosphorus fertilizers, and insufficient medium and trace fertilizers

6. The external environment and human operation cause wounds

[0005] In the prior art, liquid fertilizer spraying or quick-acting medicaments are mostly used to treat plant black spot. The curative effect is fast and the drug effect is short, but black spot is a kind of infectious and recurring plant disease, and the long-term use of chemical preparations is easy to make plant pathogens Bacterial strains develop drug resistance and drug resistance, which increases the difficulty of control and even causes control failure
