Preventing and controlling method of orange yellow shoot

Abstract

The invention discloses a preventing and controlling method of orange yellow shoot, and aims at solving the problems of existing yellow shoot infection in the planting process of oranges and soil degradation caused by long-term planting. Bafillus natto and bacillus thuringiensis mixed bacterial suspension spraying is conducted on orange tree bodies, the breeding of yellow shoot pathogenic bacteriaand orange cryptophagus decoratus carrying the yellow shoot pathogenic bacteria can be effectively inhibited, and the use of pesticide is reduced; on the other hand, fertilizer application can be selectively conducted according to the growth period of the oranges, by the matching of different fertilizer and fertilizer application manners, the disease resisting capability of fruit trees is improved, the fertilizer utilization rate of the oranges is improved, the absorbing effect of the fertilizer is improved, and soil environment can be improved to a certain extent through liquid microbial inoculum and solid microbial inoculum, and the sustainable planting of the oranges can be ensured.

Description

technical field [0001] The invention belongs to the technical field of ecological planting, and in particular relates to a method for preventing and controlling citrus huanglongbing. Background technique [0002] Huanglongbing is caused by a Gram-negative bacterium confined to the phloem, and is the most harmful disease in the production of citrus and grapefruit in my country. It mainly occurs in Guangdong, Guangxi, Fujian and Taiwan. [0003] In the field, it is mainly transmitted by citrus psyllids transfer and feeding, diseased seedlings and scions and other reproductive materials. Seedlings and saplings will die within one to two years after suffering from Huanglongbing, and adult trees will lose fruiting ability or die within three to five years after the onset, which is an incurable disease of citrus. Honey pomelo belongs to the citrus plant of the citrus genus of Rutaceae, and Huanglongbing is also susceptible to infection on honey pomelo. [0004] The existing met...

Problems solved by technology

[0006] Aiming at the above-mentioned technical problems, the present invention provides a method for the prevention and control of citrus Huanglongbing to solve the problems of Huanglongbing infection and long-term planting soil degradation in the existing citrus planting process. Methods By improving the way of fertilizer application and the selective addition of microorganisms, the disease resistance of fruit trees can be improved, which can effectively prevent and control Huanglongbing. At the same time, the utilization rate of chemical fertilizers can be improved, soil chemical residues can be degraded, and the environment of soil flora can be improved.
