Growth-promoting bacteria for promoting ginger growth and preventing and controlling continuous cropping ginger soil-borne wilt and microorganism organic fertilizer produced from growth-promoting bacteria

Abstract

The invention relates to growth-promoting bacteria for promoting ginger growth and preventing and controlling continuous cropping ginger soil-borne wilt and a microorganism organic fertilizer produced from growth-promoting bacteria, belonging to the technology of intensive agriculture production. A growth-promoting bacterial strain NJPRHSDAQ-1 is obtained through separation, and is inoculated into a microbial decomposition mixture of cured pig manure compost and rapeseed meal for solid fermentation so as to prepare the microorganism organic fertilizer, the fertilizer comprises more than 1*10<8>cfu/g of growth-promoting bacteria and 4-5% (above 90% of organonitrogen) of total nitrogen, the total nitrogen phosphorus and potassium nutrient is 6-10%, and the organic content is more than or equal to 45%. A pot experiment result proves that the rate for preventing and controlling the ginger soil from having the wilt achieves above 75%, and if being applied to soil in which the ginger is planted, microorganism organic fertilizer can prevent and control ginger soil-borne wilt.

Description

1. Technical field [0001] The invention relates to growth-promoting bacteria and microbial organic fertilizers for promoting the growth of ginger and preventing and controlling soil-borne blight of continuous cropping ginger, belonging to the technical field of agricultural intensive production. 2. Background technology [0002] Ginger soil-borne blight is a typical soil-borne disease, which seriously affects the yield and quality of ginger. Ginger wilt mainly harms underground tubers. The pathogenic bacteria of the disease are Fusarium oxysporum and Fusarium solani. The disease can occur after 2 to 3 consecutive crops, and it will become more serious after 5 years of continuous cropping. If there is no method and approach for preventing and controlling the disease, the growth of ginger plants will be difficult to sustain. Our results show that the key problem of soil-borne blight of continuous crops is not nutrient deficiency or imbalance, nor secondary salinization of soi...
