Problems solved by technology

[0003] In terms of crop cultivation in my country, chemical fertilizers have been used for more than 50 years. Although chemical fertilizers have played a significant role in increasing production and income, long-term application will damage the soil, resulting in a decline in soil organic matter and a serious imbalance in the proportion of various nutrients. , the soil began to acidify and half-cut, and the physical and chemical properties of the soil and soil microbial flora were severely damaged, resulting in a decrease in its water storage and fertilizer retention capacity and poor air permeability, making it difficult to meet the growth needs of crops; The use will also cause environmental pollution

Embodiment 1

[0024] An organic soil conditioner is prepared by fermentation of the following materials: 50 kg of municipal sludge, 10 kg of mushroom dregs, 20 kg of rice husk powder, 10 kg of vermiculite, and 10 kg of Bacillus subtilis.

[0025] The specific preparation method is:

[0026] 1) Weigh all the raw materials except Bacillus subtilis according to the above ratio, crush them until they pass through an 80-mesh sieve, and mix them evenly;

[0027] 2) Take out the Bacillus subtilis that has undergone tertiary cultivation and propagation according to the above ratio, mix it with the raw materials in step 1), adjust the humidity of the mixed material at about 40%, and carry out aerobic solid-state fermentation at room temperature, and the fermentation temperature is 20-60 degree, the fermentation time is 12 days.

[0028] 3) The product obtained in step 2) is dried at low temperature, and then crushed through a 100-mesh sieve to obtain the organic soil conditioner.

Embodiment 2

[0030] An organic soil conditioner is prepared by fermentation of the following materials: 40 kg of municipal sludge, 20 kg of mushroom dregs, 20 kg of rice husk powder, 15 kg of vermiculite, and 15 kg of Bacillus subtilis.

[0031] 1) Weigh all the raw materials except Bacillus subtilis according to the above ratio, crush them until they pass through an 80-mesh sieve, and mix them evenly;

[0032] 2) Take out the Bacillus subtilis that has undergone tertiary cultivation and propagation according to the above ratio, mix it with the raw materials in step 1), adjust the humidity of the mixed material at about 40%, and carry out aerobic solid-state fermentation at room temperature, and the fermentation temperature is 20-60 degree, the fermentation time is 15 days.

[0033] 3) The product obtained in step 2) is dried at low temperature, and then crushed through a 100-mesh sieve to obtain the organic soil conditioner.

Embodiment 3

[0035] The field test was carried out from April to June 2015 in a cotton field in the north of Shihezi City, Xinjiang. The basic physical and chemical properties of the soil are: clay, organic matter content 0.813%, available nitrogen 53.21ppm, available phosphorus 8.17ppm, available potassium 227ppm, soil Salt 0.91, pH 8.9. The tested crop variety was Xinkaiyu 13. Three treatments were set up in the test. Treatment 1 was the control without soil conditioner; Treatment 2 was the organic soil conditioner of the present invention; Treatment 3 was a certain brand of soil conditioner purchased from the Shihezi Agricultural Materials Store. Apply evenly to the surface one day before irrigation, and the dosage per mu is 1kg. The area of ​​the community is 100m 2 , arranged in random blocks, repeated 3 times, and field management was in accordance with local customs. After 20 days, take a 0-20cm soil sample according to the five-point sampling method to measure the salinity and p...

Abstract

The invention provides an organic soil conditioner and a preparation method thereof. The organic soil conditioner is prepared by adding vermiculite, mushroom residues, rice hull powder and bacillus subtilis to municipal sludge, carrying out aerobic composting fermentation and then carrying out low temperature drying and grinding. The organic soil conditioner provided by the invention has the beneficial effects that the organic soil conditioner can effectively relieve soil hardening caused by applying excessive chemical fertilizers, improve the soil structure, store water to preserve soil moisture, improve the soil permeability and water-bearing property and supplement K, Mg, Ca, Fe and trace elements, such as Mn, Cu, Zn and Si, in soil; and the active substances generated in the bacillus subtilis thalli growth process, such as subtilin, polymyxin, nystatin and gramicidin, have obvious inhibiting effects on pathogens or opportunistic pathogens causing endogenous infection, thus reducing the occurrence rates of crop diseases.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an organic soil conditioner and a preparation method thereof. Background technique [0002] Vermiculite, with good cation exchange and adsorption, can improve the structure of the soil, store water and moisture, improve the air permeability and water content of the soil, and turn the acidic soil into a neutral soil; vermiculite can also play a role in the soil. Buffer function, hinder the rapid change of PH value, make the fertilizer slowly released in the crop growth medium, and allow a little excessive use of fertilizer without harm to the plant; vermiculite can also provide the crops with K, Mg, Ca, Fe contained in themselves And trace elements such as Mn, Cu, Zn. The water absorption, cation exchange and chemical composition characteristics of vermiculite make it play multiple functions such as fertilizer retention, water retention, water storage, ventilation and mi...
