Abstract

The invention belongs to the field of biologics, and provides a microorganism agent for preventing and controlling citrus huanglongbing. The agent consists of two or more than two known original bacteria and a matrix containing multiple microelements, wherein the actinomycete as a main bacterium in a composite flora accounts for 60-90%, the plant bacillus as an auxiliary bacterium accounts for 10-40%, and the ratios of various bacterium components are changed according to different soil environment conditions and fertilization conditions. The selected bacteria are amplified, optimized and intensified in a complex and variable ecological environment and are cultured into a multifunctional flora. The flora can breed in citrus plant root soil and can infect citrus plants, brings the effect of treating bacteria by using bacteria to prevent and control citrus huanglongbing into play, and can also provide nitrogen, phosphorus and potassium nutrient elements to citruses to bring the effect of a biological fertilizer into play.

Description

technical field [0001] The invention belongs to the field of biology, and in particular relates to a microbial agent for preventing and treating citrus huanglongbing and a production method. Background technique [0002] As the world's largest fruit, citrus has an annual output of 100 million tons and a planting area of ​​100 million mu. There are 140 countries and regions that cultivate citrus, mainly concentrated in Brazil, the United States, China and the countries along the Mediterranean Sea; in 2002, the world citrus trade volume reached more than 8.2 billion U.S. dollars, and it is the third largest traded agricultural product next to wheat and corn [0003] Huanglongbing (English: Huanglongbing, English abbreviation: HLB) is a devastating disease that threatens the survival and development of the citrus industry. At present, 11 of the 19 provinces and regions that grow citrus oranges in my country have suffered from Huanglongbing, and the affected area accounts for 80...
