Embodiment 1

[0021] The soil conditioner of the present invention includes decomposed organic materials accounting for no less than 65.0% of the mass ratio of the soil conditioner, phosphogypsum accounting for 25% to 30% of the mass ratio of the soil conditioner, and a bacterial content of no less than 2×10 8 CFU / g of Bacillus amyloliquefaciens, pH of soil conditioner: 6.0-6.5.

[0022] The Bacillus amyloliquefaciens HFJ-7 with the preservation number of CGMCC No. 10011 is used as the Bacillus amyloliquefaciens. The depository unit of the Bacillus amyloliquefaciens HFJ-7: General Microbiology Center (CGMCC) of China Microbiological Culture Collection Management Committee; Address: No. 3, Yard 1, Beichen West Road, Chaoyang District, Beijing, Institute of Microbiology, Chinese Academy of Sciences; date of deposit : November 19, 2014; the deposit number of Bacillus amyloliquefaciens is CGMCCNo.10011.

[0023] The decomposed organic material is prepared from chicken manure and edible fungus ...

Embodiment 2

[0033] Embodiment 2, application in solar greenhouse soil

[0034] Four solar greenhouse soils with a planting area of ​​about 1.5 mu and continuous planting for more than 3 years were selected as the research objects. Evenly spread 600kg / mu of the soil conditioner of the present invention in the whole facility, deep plow and mix with the soil, plant crops as big red tomatoes, and continuously track and measure changes in soil organic matter, number of beneficial microorganisms, >0.25mm water stability Agglomerates, soil pH and other indicators were measured every 10 days, a total of 5 times. The water-stable aggregates of soil larger than 0.25mm are measured by wet sieving method. In order to ensure the accuracy of the test, no other organic, chemical, biological and other products that affect the test results are added during the test.

[0035] The result is as figure 1 As shown, the proportion of water-stable aggregates larger than 0.25 mm in the 1-4# greenhouse soil inc...

Embodiment 3

[0036] Embodiment 3, the application in arch shed soil

[0037]The test site is in a watermelon shed in Qingzhou, and the soil conditioner of the present invention is evenly spread according to the amount of 500 kg per mu, the ground is turned and mixed, and Luqing No. 7 watermelon is planted, and the soil organic matter is tracked and measured every 25 days after planting. Watermelon content, proportion of >0.25mm water-stable aggregates, pH value, bacteria count and other indicators were measured three times; watermelon yield was measured at harvest. The control group did not use soil conditioner throughout the growth period. The experimental results are shown in Table 1.

[0038] Table 1 is the impact of the soil conditioner on soil organic matter content, bacterial count, pH, aggregate structure and watermelon yield

[0039]

[0040] The results in Table 1 show that the application of soil conditioner can optimize the soil environment and the growth and development ...

Abstract

The invention provides a soil conditioner for improving and remediating soil and application thereof. The soil conditioner is prepared from decomposed organic material, phosphogypsum and bacillus amyloliquefaciens, wherein the mass ratio of the decomposed organic material in the soil conditioner is not lower than 65.0%, the mass ratio of phosphogypsum is 25%-30%, and the content of bacillus amyloliquefaciens is not lower than 2*10<8> CFU/g. The soil conditioner has an obvious soil conditioning and remediating function and can effectively promote formation of soil granular structures, improve the soil buffer capacity and the water and nutrient retention capacity, enrich beneficial microbial florae in soil, improve soil bioactivity, improve soil acidity and alkalinity and significantly condition and remediate greenhouse soil.

Description

technical field [0001] The invention belongs to the technical field of soil conditioning, and relates to a soil conditioner, in particular to a soil conditioner for improving and repairing soil and an application thereof. Background technique [0002] "Planting the land first raises the land". The health of the soil is an important factor affecting agricultural planting. Only healthy soil can cultivate healthy plants and ensure the health of animals and humans. Healthy soil is mainly reflected in the superior soil physical and chemical properties, rich soil nutrients, biological activity and healthy and stable ecosystem. With the increase of land multi-cropping index, excessive application of chemical fertilizers, and unscientific use of manure, the quality of cultivated land has been seriously degraded, the content of soil organic matter has decreased, and the ecosystem of cultivated land has also been severely damaged. [0003] Soil conditioner can adjust soil structure, ...
