Planting method for controlling infection of citrus tristeza virus on newly-grown citrus seedlings

Abstract

The invention discloses a planting method for controlling the infection of the citrus tristeza virus on newly-grown citrus seedlings. The planting method includes the steps that terrestrial citrus seedlings are loaded with a nutrition pot filled with nutrition soil or field soil, then the nutrition pot loaded with the terrestrial citrus seedlings is put into a greenhouse to be cultivated in a centralized mode or centralized in farmland to be cultivated, a black mulching film or a light reflecting mulching film is used for covering the ground of the farmland, the farmland is relatively independent, and citrus planting does not exist in the far peripheral range; the young shoot emerging time, the shoot emerging amount and the young shoot growing height of each batch are recorded; the pest and disease damage occurrence on the citrus seedlings is regularly detected, spraying preventing and controlling are conducted purposefully, a diaphorina citri killing pesticide is sprayed in the shoot stage, meanwhile, pests such as aphids and leaf miners are controlled, and disease preventing and controlling are conducted according to a conventional method; the tristeza virus is detected every year, and if trees infected with the tristeza virus are found, the tristeza virus infected with the tristeza virus are removed immediately; the citrus seedlings are fixedly planted into a field after two years. The planting method can effectively lower the risk of infecting the citrus tristeza virus and even eliminate the citrus tristeza virus.

Description

Technical field: [0001] The invention belongs to the field of prevention and control of agricultural diseases and insect pests, and in particular relates to a planting method for controlling citrus huanglongbing infection of new citrus seedlings. Background technique: [0002] my country is a big citrus producing country in the world. The citrus industry is the pillar industry of our country's agriculture. It occupies an extremely important position in the agricultural economy and plays an extremely important role in increasing farmers' income, increasing social employment and building a new socialist countryside. Citrus pests and diseases are major obstacles to the development of the citrus industry, the most serious of which is citrus huanglongbing, known as the "cancer" of citrus. With the rapid development of citrus production, the occurrence and damage of citrus huanglongbing are becoming more and more serious. The disease is a very harmful infectious disease. The path...

AI Technical Summary

Problems solved by technology

This method has the following problems: (1) the root system of terrestrial seedlings is damaged to varying degrees when transplanted, so the survival rate will be relatively low, and when it is important, the root system needs time to recover, so the growth is slow

(2) Due to the slow growth, the fruit will gradually bear fruit after the third year, so the farmers often neglect management. As a result, the citrus psyllids in the orchard are seriously damaged, and Huanglongbing has been infected before the fruit bears.

(4) The management of plant diseases and insect pests is very difficult, because the seedlings are small and the planting is scattered, so the management of plant diseases and insect pests is difficult, the cost is high, and the effect is poor.
