Embodiment 1

[0018] A kind of production method of nutrient soil is characterized in that comprising the following steps:

[0019] 1) Take straw with a volume of 1m3, and cut it into small pieces of straw with a length of about 10cm with a knife;

[0020] 2) Take 50kg of soil from under the haystack or rotten leaves, and crush the soil into particles with a diameter less than 2cm;

[0021] 3) After mixing the soil particles and small pieces of straw evenly, pile them into a steamed bun-shaped pile, spray 150kg of tap water on the pile, then cover the pile with a plastic film, and ferment for 35 days;

[0022] 4) Remove the plastic film, and crush the fermented straw with a grinder into crushed particles with a length of 0.1cm-1cm;

[0023] 5) Add 5 kg of urea, 5 kg of potassium sulfate, and 3 kg of potassium dihydrogen phosphate to the crushed particles prepared in step 4), mix the fertilizer and the crushed particles evenly, spray 50 kg of tap water, spread them on the road to dry, ...

Embodiment 2

[0025] A kind of production method of nutrient soil is characterized in that comprising the following steps:

[0026] 1) Take straw with a volume of 1m3, and cut it into small pieces of straw with a length of about 10cm with a knife;

[0027] 2) Take 60kg of soil from haystacks or rotten leaves, and crush the soil into particles with a diameter of less than 2cm;

[0028] 3) After mixing the soil particles and small pieces of straw evenly, pile them into a steamed bun-shaped pile, spray 120kg of tap water on the pile, then cover the pile with a layer of plastic film, and ferment for 40 days;

Abstract

The invention discloses a production method for nutrient soil. The production method is characterized by comprising the following steps of taking 1 m <3> by volume of straws, cutting the straws into small straw sections with the length of about 10 cm, degrading the straws into small granular active molecules after solid fermentation, and preparing the nutrient soil by mixing nitrogen fertilizer, potassium fertilizer and phosphate fertilizer. According to the production method, the straws are degraded into the small granular active molecules by using the solid fermentation of the straws; the small granular active molecules can be used as an organic fertilizer, so that destruction to ground-surface environment and atmosphere environment during a straw burning process can be prevented.

Description

technical field [0001] The invention relates to a method for recycling straw, in particular to a method for producing nutrient soil. Background technique [0002] After the crops are harvested, a large amount of straw will be produced. These straws contain huge energy. However, at present, farmers often burn the straws and burn them directly in the field. This treatment method not only destroys the environment, but also releases a large amount of The heat will kill the microorganisms on the surface, causing soil compaction, which is not conducive to the growth and production of crops. The burning of straw will also cause energy loss. The N and S elements in the straw are basically released into the atmosphere directly in the form of gas. [0003] At the same time, the development of organic fertilizers is still in its infancy. Agricultural production is basically dominated by chemical fertilizers. Chemical fertilizers have certain nutrients for the growth of crops, especiall...
