Problems solved by technology

However, the degree of biological utilization of filter mud in sugarcane sugar factories is at a low level, a small amount is used as fertilizer, and most of it is discarded (Bao Guoyu. Discussion on technical and economic policies for comprehensive utilization of sugarcane sugar resources [J]. Sugarcane Industry, 1993, ( 1):59-64)

Embodiment 1

[0039] 1. Obtaining straw

[0040] Farmers buy it and break it into powder.

[0041] 2. Obtaining filter mud

[0042] Purchased from sugar cane mills, passed through a 100-mesh sieve

[0043] 3. Production of Trichoderma hartzii inoculant

[0044] The strain preservation number of Trichoderma harzianum SQR-T037 is CGMCC NO.3308. Here, only taking Trichoderma harzianum SQR-T037 as an example to explain the specific technical scheme and effect of the present invention, other sources have antagonistic effect on plant pathogenic bacteria. Trichoderma can be used in the present invention.

[0045] Inoculate Trichoderma on a PDA plate, wait until it covers the entire plate, scrape off the mycelia with a blade, filter with sterile gauze, rinse with sterile water, filter out the mycelium, and make a spore liquid with a spore concentration of about 4 ×10 7 per g, stored in a refrigerator at 4°C, and used for inoculation. Inoculate the above-mentioned Trichoderma spore liquid into...

Abstract

The invention provides a method for producing trichoderma bio-organic fertilizer from straw and filtrated mud and an obtained product. Ingredients comprise straw of crops (such as rice, corn and the like), filtrated mud, water (common tap water) and common organic fertilizer. The technological process comprises the steps that the straw and the filtrated mud are mixed according to the mass ratio of 3:2-4:1, the water is added based the water content of 60-65%, sterilization is carried out at 115 DEG C for 30 min, 5-10% inoculation is carried out, shallow tray fermentation is carried out, the fermentation depth is 1-3 cm, the fermentation temperature is 22-28 DEG C, fertilization lasts for 7 days, and after fertilization, fermentation solid and the common organic fertilizer are mixed according to the mass ratio of 1:8-1:10 to form the bio-organic fertilizer. The trichoderma spore number of per g of produced fertilizer is larger than 2*10<7>, the total nitrogen, phosphorus and potassium nutrient content is larger than or equal to 5%, the organic matter content is larger than or equal to 45%, and the growth promotion effect is good.

Description

technical field [0001] The invention belongs to the technical field of agricultural intensive production, and relates to a method for producing trichoderma bio-organic fertilizer by using straw and filter mud and the obtained product. Background technique [0002] Agriculture is the basic industry of our country and has always occupied an important position in the national economy. Over the past 30 years, my country's grain production has achieved significant growth, and the extensive use of chemical fertilizers is an important factor supporting the increase in grain production. my country consumes more than 30% of the world's chemical fertilizers with 8% of the world's arable land. While increasing food production, long-term excessive use of chemical fertilizers has also brought about problems such as environmental pollution, soil compaction, soil fertility decline, ecological deterioration, and decline in the quality of agricultural products (Guo J H, Liu XJ, Zhang Y, et a...
