Abstract
The present invention relates to the antagonistic bacteria for controlling the Fusarium wilt of continuous cropping banana and their microbial organic fertilizer. It belongs to technology of intensive agricultural production. The present invention separates two antagonistic bacteria NJN-6 and NJN-11 and produces the microbial organic fertilizer through inoculating the two said strains into pig manure compost and rapeseed cake compost to conduct solid-state fermentation. The microbial organic fertilizer is characterized in that in the fertilizer, the content of each of the antagonistic bacteria NJN-6 and NJN-11 is above 1×108 cfu/g, total nitrogen is 4˜5% (weight percent), above 90% (weight percent) of the total nitrogen is organic nitrogen, total nitrogen-phosphorus-kalium nutrient is 6˜10% (weight percent) and organic matter is 30˜35% (weight percent). The results of experiment showed the showed that the prevention rate of the Fusarium wilt of banana reached more than 80% and the incidence rate can be controlled to less than 5% even on the seriously diseased terraces (seasonal incidence rate of 15% or more). The fertilizer can control the wilt effectively if they are applied to so…
