Banana stem and leaf residue decomposing inoculant for inhibiting fusarium wilt and preparation method thereof

Abstract

The invention discloses a banana stem and leaf residue decomposing inoculant for inhibiting fusarium wilt and a preparation method thereof. The banana stem and leaf residue decomposing inoculant is prepared by using trametes versicolor with a cellulose, lignin and hemicellulose decomposing function, trichoderma citrinoviride, aspergillus oryzae, bacillus amyloliquefaciens with a biological control function, and streptomyces pristinaespiralis for compound fermentation. The banana stem and leaf residue decomposing inoculant can effectively accelerate the decaying of banana stem and leaf residues returned to the field, while inhibiting the growth of fusarium wilt of banana and other pathogenic bacteria; the decomposition of the banana stem and leaf residues is accelerated after applying the decomposing inoculant in the field, wherein the weight loss rate of the banana stem and leaf residues is increased remarkably; the tensile force of the banana stem and leaf residues is reduced remarkably; the number of soil pathogens including antagonistic bacillus and actinomycetes is increased remarkably; and the number of pathogenic organisms is reduced remarkably.

Description

technical field [0001] The patent of the invention relates to a banana stem and leaf residue decomposing bacterial agent for inhibiting fusarium wilt and a preparation method thereof, belonging to the technical field of agricultural microorganism application. Background technique [0002] Due to the characteristics of fast growth and high biomass of bananas, almost the same amount of by-products of banana stems and leaves are produced during the production of bananas. It is estimated that every 1hm produced 2 Bananas can produce 600-900 tons of stalks, and their resources are very rich. As a special agricultural waste, banana stems and leaves are rich in nutrients compared with other crop stalks, and the carbohydrate content in banana stems and leaves is high. , bulbs and roots contain an average of 57 grams of nitrogen, 6.6 grams of phosphorus, and 232 grams of potassium. If the average utilization rate is calculated as 22%, 4% and 46.22% respectively, the utilization rate...

AI Technical Summary

Problems solved by technology

[0006] However, the existing methods of utilizing banana stems and leaves are basically ectopic (not carried out at the original planting site), and have not fundamentally solved the problem of its removal, and will also cause some plant pathogens (such as Fusarium wilt) leads to the occurrence of other planting diseases

Therefore, if you want to decompose in situ, you must solve two problems: one is to quickly degrade the fibers in the banana stems and leaves; the other is to suppress or kill the pathogenic bacteria in the banana stems and leaves.
