Problems solved by technology

[0003] In order to solve the problem that the efficiency of the existing methods for treating straw by earthworms is not high, and the straw needs to be decomposed first, the present invention provides a new method, which can make the straw and other wastes into a mixed material, which can improve the efficiency of earthworms. Efficiency of handling straw

Embodiment 1

[0010] Embodiment 1: Material ratio test of earthworm digestion straw

[0011] 1. Materials

[0012] The "Daping No. 2" earthworm was used in the experiment, which was provided by the earthworm breeding base of the experimental farm and pasture of Yangzhou University. Rice straw and sludge are obtained from farmers and domestic sewage treatment plants.

[0013] 2. Method

[0014] Put earthworms (2kg, calculated on a wet basis)-wormcasting 84.7kg (50kg on a dry basis) mixture in advance in a homemade wooden culture frame (100cm×100cm×40cm) with a 0.2mm aperture nylon screen as the bottom. The mass ratio (kg / kg) of rice straw and sludge treated in advance into 10cm long was 66.3 / 0, 59.7 / 18.8, 53.1 / 37.6, 46.4 / 56.4, 39.8 / 75.2 and 33.2 / 94.0 (combined dry basis mass ratio respectively 100 / 0, 90 / 10, 80 / 20, 70 / 30, 60 / 40 and 50 / 50) fully mixed (converted dry weight is 50kg, wherein the moisture content of straw and sludge are 24.6%, 73.4% respectively ) on it, and when 1 / 4 of the s...

Embodiment 2

[0022] An example of the present invention is, every mu of land builds worm bed 500m 2 , mix 60% of straw with 40% of livestock manure or domestic sludge, and the mixture is stacked into long stacks with a height of about 20cm, a width of about 40cm, and a length of about 3.5m, and each stack is separated by about 15cm. Cover the mixture of domesticated working earthworms and vermicompost on the long piles of organic material mixtures such as straw, and the input amount of earthworms is 0.5kg / m 2 It is advisable to cover the vermicompost with a thickness of 3-5cm. If it is too thick, it will not be conducive to ventilation, and if it is too thin, it will lose water quickly, which is not good for the survival of working worms. When covering vermicompost, the mixture of organic materials such as straw should be completely covered. When about 50-60% of the mixture of organic materials such as straws is digested, add materials immediately. The vermicompost and the earthworm mixtu...

Abstract

The invention belongs to the technical field of biological digestion of agricultural solid organic waste, and in particular relates to a method for digesting straw by earthworms. The method is as follows: after the straw is crushed, the straw and livestock manure or domestic sludge are formulated into a mixed material in a weight ratio of 6:4, and then earthworms are inserted into the mixed material for biological digestion. The method of the invention can safely inoculate earthworms on organic material mixtures such as straws, which is environmentally friendly and safe, and the growth of working worms is good. The amount of finished product worms is large, the number of eggs is large, and the digestion efficiency is high. The average daily consumption of organic material mixtures such as straws The amount is 2-3 times the body weight of earthworms.

Description

technical field [0001] The invention belongs to the technical field of biological digestion of agricultural solid organic waste, is an organic part of the resource utilization technology of farmland straw, and specifically relates to a method for earthworm digestion of straw. Background technique [0002] There is a huge amount of crop straw in my country, about 50% of which have not been effectively treated and utilized. Some stalks are burned directly, which not only wastes resources, but also causes serious air pollution, even triggers fires and affects the operation safety of highways and civil aviation. Crop straw contains carbon, nitrogen, phosphorus, potassium, silicon, calcium, magnesium, sulfur and various trace elements, and is rich in organic substances such as cellulose, hemicellulose and protein. It can be used for silage, gasification, field return, bio-fertilizer, construction raw material, etc. It is a beneficial attempt to use earthworms to digest and tran...
