Agricultural ecological technique capable of preventing and controlling liberobacter asiaticum as well as harvesting organic oranges

Abstract

The invention discloses an agricultural ecological technique capable of preventing and controlling liberobacter asiaticum as well as harvesting oranges. The agricultural ecological technique is characterized by comprising production and culture: a biological organic fertilizer is used, a metabolic photosynthetic accelerant and ion liquid for improving resistance are sprayed, and a biological source agricultural chemical and artificial and mechanical weeding are used for preventing and treating diseases and pests and weeds. The agricultural ecological technique disclosed by the invention has the advantages that the productivity, the immunity, the disease resistance and the disease tolerance of the oranges can be improved; the spreading speed of the liberobacter asiaticum is reduced, so that healthy trees can obtain high yield; the trees suffering from light and moderate diseases restore the productivity which achieves or approaches the level of that of trees free from diseases; the trees suffering from serious diseases restore growing trend, definite productivity is maintained, and the fruiting period is prolonged; the fruit quality can be improved, and besides, good-quality organic orange products are harvested; the agricultural ecological technique has important significance on guaranteeing the production benefit of orange fruit growers, and promoting the steadily forward development of orange industry in rural economy.

Description

technical field [0001] The invention relates to agricultural ecological technology, in particular to an agricultural ecological technology for preventing and controlling citrus huanglongbing while harvesting organic citrus. Background technique [0002] Citrus huanglongbing is also known as yellow shoot disease, yellow wilt and green fruit disease. Citrus huanglongbing has caused great harm to citrus, and the abandoned citrus orchards have occurred heavily. If it is allowed to spread, it will cause a fatal blow to my country's citrus industry with dead trees and gardens. The pathogen of citrus Huanglongbing is Gram-negative bacteria, and the whole plant of citrus suffering from Huanglongbing is a systemic disease. The root, trunk, branch, leaf, flower, and fruit all have pathogens, especially the root. The medicine is difficult to reach and has not been found yet. Good drug delivery methods and routes, and no specific pesticides. [0003] Typical symptoms of citrus fruit f...

AI Technical Summary

Problems solved by technology

[0004] The epidermis of the diseased root is easy to detach and rot, etc. Huanglongbing bacteria colonize preferentially in the root and the distribution is relatively uniform, so only cutting off the diseased branches cannot effectively control Huanglongbing
