Problems solved by technology

[0004] Soil conditioner is for the purpose of improving soil quality, so it needs to add a lot of organic matter and humic acid; the current production method of soil conditioner on the market is mainly agricultural water-retaining agent and natural peat rich in organic matter and humic acid or other organic matter. Raw materials, supplemented by nutrients and some bioactive ingredients, are processed. The current soil conditioners have disadvantages such as complicated production process, high cost of raw materials, high product price and short duration of action.

Embodiment 1

[0020] The proportions of the fermented product of the soil conditioner of this embodiment and the microbial composite bacterial agent are as follows in parts by weight: 65 parts of fresh pig manure (water content 80%), 25 parts of straw powder (water content 15%), and 5 parts of superphosphate , 2 parts of urea, 2.5 parts of potassium chloride, and 0.5 part of microbial compound bacteria agent.

[0021] The specific production method is as follows:

[0022] Crush the collected straw into particles with a diameter of 2-3cm, add livestock and poultry manure according to the above ratio, stir evenly, then add microbial compound bacteria agent, superphosphate, urea, and potassium chloride according to the ratio, and stir evenly again, The mixture is piled into strips, the height of which does not exceed 1.1 meters, and the fermentation is carried out under the condition that the temperature of the fermentation environment is higher than 20 degrees. If the fermentation temperatur...

Abstract

The invention provides a soil conditioner. The soil conditioner comprises livestock excrement, straw powder, superphosphate, potassium chloride, urea and a microorganism composite microbial agent; themicroorganism composite microbial agent comprises a lactic acid bacterium microbial agent, a bacillus firmus microbial agent, a photosynthetic bacterium microbial agent, a bacillus stearothermophilusmicrobial agent, a bacillus subtilis microbial agent, a bacillus licheniformis microbial agent and a bacillus megaterium microbial agent. Agricultural waste is used for preparing a raw material of the soil conditioner, and the soil conditioner is environmentally friendly and low in cost and has good soil conditioning performance of water retention, fertilizer increase and air permeation.

Description

technical field [0001] The invention relates to the field of soil improvement, in particular to a soil conditioner, in particular to a soil conditioner with agricultural waste, livestock and poultry manure and crop stalks as the main raw material and a preparation method thereof. Background technique [0002] Soil conditioner is mainly made of agricultural water-retaining agent and natural peat rich in organic matter and humic acid or other organic matter, supplemented by adding various biologically active ingredients and nutrients, which can be processed to improve soil quality and increase soil fertility. It has three obvious soil conditioning properties of "water retention, fertilization, and ventilation". [0003] In theory, soil conditioners have the functions of breaking soil compaction, loosening soil, improving soil air permeability, reducing soil bulk density, promoting soil microbial activity, and enhancing soil fertilizer and water permeability; in practice, it ...
