Embodiment 1

[0031] Grind or grind 50 parts of biogas residue, 45 parts of fly ash, and 5 parts of phosphate rock powder to below 100 mesh respectively, add 0.4 parts of organic material decomposing agent, and stack retting naturally. The temperature is controlled at 45 °C and turned twice a day. Degradation is terminated after 4 days; naturally air-dried until the water content is less than 20%, forming a taupe loose material, which is packaged in bags.

[0032] The product obtained in Example 1 is detected, and each index is in the following ranges (by absolute dry weight): 48% organic matter content, 35% humic acid content, 1.9% N content, P 2 o 5 Content 1.4%, K 2 O content 1.1%.

[0033] The soil improver that embodiment 1 is made carries out field test in the farmland of land consolidation project demonstration area of ​​woodworking village, Bangui Township, Guanling County, Guizhou Province, applies 70 kilograms per mu, applies after 120 days, and applies the same amount of commer...

Embodiment 2

[0035] Grind or grind 60 parts of biogas residue, 30 parts of fly ash, and 10 parts of phosphate rock powder to below 100 mesh respectively, add 0.5 parts of straw decomposing agent, stack retting naturally, control the temperature at 40°C, and turn it twice a day. Terminate degradation; air-dry naturally until the water content is less than 20%, forming a taupe loose material, which is packaged in bags.

[0036] The product obtained in Example 2 is tested, and each index is in the following ranges (by absolute dry weight): organic matter content 53%, humic acid content 41%, N content 2.1%, P 2 o 5 Content 2.0%, K 2 O content 1.2%.

[0037] The soil improver that embodiment 2 is made carries out field test in the farmland of land consolidation project demonstration area of ​​woodworking village, Bangui Township, Guanling County, Guizhou Province, applies 50 kilograms per mu, applies after 120 days, and applies equal amount of commercially available chemical fertilizers. Rat...

Embodiment 3

[0039] Grind or grind 35 parts of biogas residue, 55 parts of fly ash, and 10 parts of phosphate rock powder to below 100 mesh respectively, add 0.2 parts of rotting agent, stack retting naturally, control the temperature at 60°C, turn it once a day, and after 3 days Terminate degradation; air-dry naturally until the water content is less than 20%, forming a taupe loose material, which is packaged in bags.

[0040] The product obtained in Example 3 is tested, and each index is in the following ranges (by absolute dry weight): organic matter content 28%, humic acid content 15%, N content 0.6%, P 2 o 5 Content 2.1%, K 2 O content 0.9%.

[0041] The soil improver that embodiment 3 is made carries out the field test in the farmland of the land consolidation project demonstration area of ​​Bangui Township, Guanling County, Guizhou Province, and applies 100 kilograms per mu. Ratio, soil organic matter content increased by 0.41%, soil bulk density decreased by 0.136g / cm 3 , crop ...

Abstract

The invention relates to a soil modifier, and a preparation method and a use method thereof. The soil modifier is obtained by mixing the following raw materials in parts by weight: 35-60 parts of biogas residue, 30-55 parts of fly ash, 5-10 parts of phosphorite powder and 0.2-0.5 part of a complex microbial agent. In the invention, the soil modifier contains various and comprehensive nutrients and a high content of organic materials; the main raw materials are recycled wastes, the production cost is very low and the production process is simple, thus favoring mass popularization and application; the raw materials are free of synthetic chemical substances and thus have no any pollution to soil environment; and the soil modifier can remarkably improve soil nutrient status and soil structureand increase crop yield, and has remarkable eco-economic benefits.

Description

technical field [0001] The invention relates to a soil additive and a preparation method and a use method thereof, in particular to a soil conditioner and a preparation method and a use method thereof. Background technique [0002] The karst mountainous area in Southwest my country is located in the center of East Asia, one of the world's three contiguous karst development areas. The karst landforms are extensively developed, the terrain conditions are complex, the ecological environment is fragile, and the soil erosion and degradation are serious. The main manifestations are: (1) soil structure degradation (soil thin layer, soil texture and soil porosity deterioration, soil structure stability decline, etc.); (2) soil water holding capacity degradation; (3) soil fertility degradation; ( 4) Soil biological degradation. Among them, soil barrenness caused by water and soil erosion, coupled with the fact that farmers use more inorganic fertilizers than organic fertilizers, lea...
