Problems solved by technology

There are a wide variety of soil amendments on the market, but the production process is generally relatively primitive. Adding too many inorganic substances will lead to poor soil quality and reduced soil activity, which will eventually lead to a continuous decrease in crop yield.
At present, there is no soil conditioner that can overcome the above-mentioned defects

Embodiment 1

[0019] Embodiment 1: A method for preparing a soil conditioner for saline-alkali land. The soil conditioner is formed by inoculating BM bacterial agent and accumulating fermentation with base material, bacterial material and additives as raw materials.

[0020] Preparation of the above-mentioned base material: 60% furfural slag was used as the main raw material, and 10% straw and 30% soybean meal were added to adjust the carbon-nitrogen ratio of furfural slag, ie, C / N, to 30:1. Evenly mix the BM powder into the furfural slag and straw mixture, the mass ratio of the mixture to the bacteria powder is 1000:1, and pile it into the fermentation tank for fermentation. The fermentation temperature is controlled at 45°C, and the tower bottom wastewater in furfural production is added to control the moisture content of the mixture at 50%. After the temperature rises to 50°C, turn the stack mechanically once a day.

Embodiment 2

[0025] Embodiment 2: A method for preparing a soil conditioner for saline-alkali land. The soil conditioner is formed by inoculating BM bacterial agent and accumulating fermentation with base material, bacterial material and additives as raw materials.

[0026] Preparation of the above-mentioned base material: 65% furfural slag was used as the main raw material, and 15% straw and 20% soybean meal were added to adjust the carbon-nitrogen ratio of furfural slag, ie, C / N, to 35:1. Evenly mix the BM powder into the mixture of furfural residue and straw, the mass ratio of the mixture to the powder is 8000:1, and pile it into the fermentation tank for fermentation. The fermentation temperature is controlled at 50°C, and the tower bottom wastewater from furfural production is added to control the moisture content of the mixture at 55%. After the temperature rises to 55°C, turn the stack mechanically once a day.

Embodiment 3

[0029] Embodiment 3: A method for preparing a soil conditioner for saline-alkali land. The soil conditioner is formed by inoculating BM bacterial agent and accumulating fermentation with base material, bacterial material and additives as raw materials.

[0030] Preparation of the above-mentioned base material: 70% furfural slag was used as the main raw material, and 20% straw and 10% soybean meal were added to adjust the carbon-nitrogen ratio of furfural slag, ie, C / N, to 40:1. Evenly mix the BM powder into the furfural slag and straw mixture, the mass ratio of the mixture to the bacteria powder is 10000:1, and pile it into the fermentation tank for fermentation. The fermentation temperature is controlled at 60°C, and the tower bottom wastewater from furfural production is added to control the moisture content of the mixture at 60%. After the temperature rises to 60°C, turn the stack mechanically once a day.

Abstract

The invention relates to a method for preparing a soil conditioner of saline-alkaline soil, in particular to a method for preparing a soil conditioner of saline-alkaline soil. The soil conditioner is prepared by the following steps of: inoculating BM microbial inoculums into base materials, fungi and additives, which serve as raw materials, and performing heap fermentation, wherein the mass ratio of the base material to the fungus to the additive is 70-80:15-20:5-10. By the soil conditioner prepared by the method, the physical and chemical properties of saline-alkali soil can be improved, the fertilizer efficiency of the saline-alkaline soil can be enhanced, nutritional substances can be provided for edaphon, soil-borne insects and diseases can be inhibited, and utilization rate of fertilizer can be improved.

Description

technical field [0001] The invention relates to a method for preparing a soil conditioner, in particular to a method for preparing a soil conditioner for saline-alkali land. Background technique [0002] The study of soil conditioners began at the end of the 19th century, when discussing how to use arid, semi-arid, and saline-alkali land. In the 1970s and 1980s, the research and development and application of soil conditioners reached a climax, and developed countries in Europe and the United States, such as the United States, the former Soviet Union, Belgium, Kuwait, and France, applied more in this regard. After 2000, developed countries have promoted and applied soil conditioners on a large scale. Soil conditioners are divided into acidic soil conditioners, nutrient soil conditioners, and organic soil conditioners according to their properties; according to their uses, they can be divided into soil conditioners for preventing soil degradation, soil conditioners for reduc...
