Microbial fertilizer for preventing and controlling citrus Huanglongbing, and preparation method thereof

Abstract

The present invention provides a microbial fertilizer for preventing and controlling citrus Huanglongbing, and a preparation method thereof. The microbial fertilizer comprises Paecilomyces lilacinus, Bacillus lincheniformis, Trichoderma and organic matter, wherein the viable organism content of the Paecilomyces lilacinus is not less than 20 million / g, the viable organism content of the Bacillus lincheniformis is not less than 10 million / g, and the viable organism content of the Trichoderma is not less than 5 million / g. According to the present invention, the three strains such as the Paecilomyces lilacinus, the Bacillus lincheniformis and the Trichoderma co-act to inhibit or damage the development process of nematode eggs so as to reduce the nematode adult rate, reduce the basis occurrence amount of orchard nematode, cut the Huanglongbing media and achieve the citrus Huanglongbing prevention and control purpose. The present invention further provides a preparation method of the microbial fertilizer.

Description

technical field [0001] The invention relates to the technical field of citrus huanglongbing, in particular to a microbial fertilizer for preventing and controlling citrus huanglongbing and a preparation method thereof. Background technique [0002] Huanglongbing, also known as yellow shoot disease, yellow wilt, green fruit disease, is an important disease of citrus, and is subject to international and domestic quarantine. Among the 17 citrus producing areas in my country, 11 are under the threat of Huanglongbing, and Guangdong, Guangxi, Fujian, Yunnan, Hainan and other places, which are the main citrus producing areas, are particularly serious. Typical symptoms of diseased citrus plants are "yellow shoots", mottled yellowing of leaves, smaller fruit, formation of worthless "green fruit" or "red nose fruit", root necrosis in the later stage of disease, tree vigor decline, resulting in leaf drop, fruit drop, plant death etc. When the disease is seriously prevalent, large are...

AI Technical Summary

Problems solved by technology

It can be seen that in the prior art, less attention has been paid to the transmission medium of citrus huanglongbing, mainly on the prevention and treatment of psyllids, and no prevention and control measures for other transmission mediums have been seen.
