Soil conditioning material with ecological restoration function for degraded agricultural land and production method thereof

Abstract

The invention discloses a method for producing a soil conditioning material with an ecological restoration function for degraded agricultural land. The method comprises the following steps of: (1) crushing straw materials and mixing with livestock and poultry manures to prepare a material A1; (2) pretreating peat, coal slime, charcoal and lignite to form granules, and mixing according to a certain proportion to prepare a material A2; (3) uniformly mixing the material A1 and the material A2 according to the proportion; (4) dissolving a phosphorus chemical waste material, namely phosphogypsum in water at the temperature of more than 80 DEG C, and rapidly adding into the mixture of the material A1 and the material A2 according to a proportion of 3 to 12 weight percent; (5) performing sodium treatment on calcium bentonite, and adding into the mixture; and (6) adding energy elements necessary for the growth and breeding of microorganisms into the mixture, adjusting proper carbon nitrogen ratio and carbon phosphorus ratio, adjusting a pH value and humidity, and fermenting. By the soil conditioning material produced by the method, soil can be fully restored, the using amount of chemical fertilizers, pesticides and mulching films is reduced, and the quality and the quantity of the products of crops are improved.

Description

technical field [0001] The invention relates to a soil conditioning material and a production method thereof, in particular to a soil conditioning material with the functions of ecological restoration of degraded farmland, water and fertilizer fixation, and slow release, which can effectively reduce the loss rate of chemical fertilizers, reduce the amount of chemical fertilizers used per unit grain yield, and quickly A soil conditioning material for improving soil fertility and a production method thereof. Background technique [0002] In modern times, the extensive application of China's farming technology and agricultural inputs (such as: chemical fertilizers, pesticide growth hormones, plastic film, etc.) has seriously damaged the benign balance system of farmland, resulting in serious and widespread degradation of farmland soil. Research data show that there are four phenomena that cannot be ignored due to soil degradation of cultivated land: [0003] 1. Chemical fertil...

AI Technical Summary

Problems solved by technology

These remind us: there are problems with the way and technology of our land use, resulting in the loss of a large amount of chemical fertilizers caused by soil degradation. While consuming a large amount of high-energy-consuming chemical fertilizers, it also brings serious non-point source pollution, which has a negative impact on the ecological environment. serious damage

Moreover, since there are no soil materials that can replace chemical fertilizers, in order to meet the population pressure, China must continue to increase the use of chemical fertilizers. Before new technologies and new soil ecological restoration materials come out, the soil degradation of farmland will continue continue

[0004] 2. Pesticide pollution: Due to the soil degradation of farmland, it cannot provide balanced and comprehensive nutrients for the growth of crops. The growth of crops is in a sub-healthy state and is easily violated by diseases and insect pests. The pesticides used bring serious pesticide pollution problems

[0005] 3. Livestock and poultry manure pollution: Due to the soil degradation of farmland, especially the destruction of the microbial environment of farmland, livestock and poultry manure cannot be decomposed, resulting in livestock and poultry manure pollution

[0006] 4. Pollution of agricultural film: Due to the soil degradation of agricultural land, the heat preservation and moisturizing functions of agricultural land have declined, and the extensive use of plastic film has brought serious "white pollution", which affects farmland mechanical farming, the extension of crop root systems, and affects the soil. structure, harmful substances accumulate year by year, and have the aftermath of completely poisoning the farmland

[0007] At the same time, the harvesting method of traditional agriculture is mainly based on the seed-type harvesting method. This method has an essential defect: people only take away the seeds from the materials grown in the farmland, and abandon the straw material, which is a negative impact on the soil. One-way output of energy and matter

Degraded farmland lacks a large amount of organic matter, and a large amount of straw materials are abandoned or burned, causing serious environmental pollution
