Problems solved by technology

The traditional earthworm processing straw technology mostly uses livestock and poultry manure or sludge after wastewater treatment mixed with crop straw for fermentation. Larger amount of sludge results in less amount of straw to be treated
In the process of sludge composting, because the sludge in the formula contains heavy metal harmful elements, this method of breeding earthworms will cause the accumulation of biotoxins, which is harmful to earthworms and the environment

Embodiment Construction

[0013] 1. Ingredients: 80% powdery waste crop straw + 20% crushed and dried peel or vegetables + strong bacteria agent.

[0014] 2. Materials: "Taiping No. 3" earthworms were used, provided by Hunan Ruifeng Agriculture Co., Ltd. Rice stalks, fruit peels, and mixed vegetable waste were collected from the surrounding villages and markets of Heilongjiang University of Science and Technology.

[0015] 3. Self-made earthworm breeding box: made of PP (polypropylene), 17cm in length, 11.7cm in width, 5.6cm in height, and 750ml in volume, transparent square thickened plastic fresh-keeping lunch box; it is equally spaced between the bottom and the top of the lunch box There are 52 holes, and the diameter of the small hole is about 1-2mm; there are 40 holes on each side of the longer side of the lunch box.

[0016] 4. Raw material pretreatment: After cutting the rice straw into small pieces of about 2.0 cm with a guillotine, use a pulverizer to crush the straw into a powder of about 1-...

Abstract

The invention belongs to the technical field of agricultural solid organic waste biological treatment, and specifically relates to a method for treating straw in a microorganism and earthworm coupled system. According to the method, the straw is treated while an earthworm feed is prepared without fermentation by using powdery waste crop straw, broken and dried fruit peel and vegetable as well as a microbial agent. The preparation parameters are as follows: (1) uniformly mixing 80% of the powdery waste crop straw and 20% of the broken and dried fruit peel and vegetable; (2) adding the high microbial agent into the earthworm mixed feed. The earthworm feed produced by the method is popular for earthworm, high in quality and high in efficiency; the problems that the crop straw remains and pollution is generated by incineration can be effectively solved, meanwhile the straw treatment time is shortened without fermentation, and generated earthworm excrement is converted into efficient bio-organic fertilizer, so that the development prospect is extremely wide.

Description

technical field [0001] The invention belongs to the field of biological treatment of agricultural solid waste, and in particular relates to a method for treating straw with a microbe-earthworm coupling system. Background technique [0002] At present, the theoretical resources of major crop straws in my country are 1.04 billion tons, the amount of collectable resources is 900 million tons, the utilization amount is 720 million tons, and the comprehensive utilization rate of straw is 80.1%. Fertilization of straw accounts for 43.2% of the amount of collectable resources; straw feed accounts for 18.8% of the amount of collectable resources. In the future, my country will further increase the comprehensive utilization of straw. The traditional earthworm processing straw technology mostly uses livestock and poultry manure or sludge after wastewater treatment mixed with crop straw for fermentation. A larger amount of sludge resulted in a smaller amount of straw to be treated. I...
