Abstract

The invention discloses a straw organic fertilizer and a preparation method thereof. The preparation method is to use a microbial inoculum used for degrading straw to ferment straw so as to obtain thefertilizer; the active ingredients of the microbial inoculum for degrading straw comprise Trichoderma viride, Trichoderma aureoviride and forage Paenibacillus pabuli. The colony formation unit ratioof Trichoderma viride to Trichoderma aureoviride and forage Paenibacillus pabuli in the microbial inoculum is (0.8-1.2):(0.8-1.2):(0.8-1.2). The fertilizer used for degrading straw can be used as a base fertilizer and can obviously improve the quality of vegetables.

Description

technical field [0001] The invention relates to a straw organic fertilizer and a preparation method thereof. Background technique [0002] Crop straw is a potential non-competitive resource, which has the characteristics of large quantity, wide distribution and variety. According to reports, the total annual output of various crop straws in my country is more than 700 million tons, including 230 million tons of rice straw, 220 million tons of corn straw, 1 billion tons of beans and autumn miscellaneous grains, and 100 million tons of peanuts, potato vines and beet leaves. tons, accounting for about 30% of the world's total straw production. However, these straw resources have not been rationally developed for a long time. Traditionally, straw is used as fuel for farmers or roughage for livestock, and a small amount is used for papermaking. In recent years, due to the sharp decline in the living fuel of farmers, the amount of direct or decomposed straw returning to the field...
