Problems solved by technology

[0003] At present, root-knot nematodes are mainly removed by root-soaking pesticides, and guava planting does not specifically control root-knot nematodes. Guava fruit trees are perennial fruit trees and will not be planted once a year. Therefore, the older the tree, the more vulnerable it is Root-knot nematode damage, for example, Chinese patent CN 103733933B discloses a cultivation method of guava fruit trees, the production steps of the invention are: land selection and gardening, fertilizer and water management, bagging and shaping, the invention does not disclose how to cultivate Guava achieves the purpose of controlling root-knot nematode

Abstract

The invention belongs to the technical field of fruit tree planting and cultivating, and discloses a multiple-cropping cultivation technology for pearl guavas. According to the technology, grafting is conducted through local small guava variety fruit trees and good-variety pearl guava fruit trees, and multiple-cropping planting is conducted by enhancing seedling management after grafting cultivation and comprises the steps of seedling raising, land preparing, field planting, multiple cropping of potatoes, mulching film covering, field managing, training and pruning and multiple cropping of tagetes erecta. The purpose of eliminating root-knot nematode disease damage is achieved through multiple cropping of the potatoes and the young guava seedlings and multiple cropping of the tagetes erecta and the strong guava seedlings, a benign ecological environment suitable for the pearl guavas, the potatoes and the tagetes erecta is continuously studies and created by enhancing management in the planting process, and then the purposes of preventing and controlling the root-knot nematode disease damage, increasing the survival rate of the guava fruit trees and effectively increasing the land utilization rate are achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of fruit tree planting and cultivation, in particular to a technique for multiple cultivation of pearl guava. 【Background technique】 [0002] Pearl guava, the meat is very soft, the gravy is rich, the taste is sweet, almost seedless, the fruit is oval, the color is milky green to milky white, it is extremely beautiful, it contains a lot of potassium, iron, carotene, etc., and it is extremely nutritious. Guangxi is located in my country In the south, the climate is mild and humid, which is suitable for the growth and reproduction of root-knot nematodes. Root-knot nematodes are common diseases and insect pests of guava. Root-knot nematodes have many pathogens and are highly contagious, and the transmission channels are complicated. It is difficult to prevent and control them. The growth of the guava fruit tree is weak, and the symptoms are similar to drought and lack of fertilizer and water. The new leaves bec...
