Alkaline soil conditioner and preparation method thereof

Abstract

The invention discloses an alkaline soil conditioner and a preparation method thereof. The preparation method comprises the following steps: mixing furfural and vinegar residues and determining the acid-base value of the obtained carrier material after mixing, wherein the mass of the furfural and the mass of the vinegar residues are equal and are both 500 kg for per mu of soil, and the acid-base value is 5.4; adding corn straw and rice husk into the carrier material, wherein the addition amounts of the corn straw and rice husk are 188.676 kg / mu and 2666.8 kg / mu; adding a bean cake on the basis of the above-mentioned material, wherein the application amount of the bean cake is 728.036 kg / mu; adding a biocontrol functional bacterium--Bacillus subtilis on the basis of the above-mentioned material, wherein the application amount of the biocontrol functional bacterium is 0.5 kg / mu; and adjusting the acid-base value of the composite soil conditioner to 2 with dilute acid so as to meet requirements on improvement of alkaline soil of different degrees. According to the invention, current waste agricultural resources are recycled, so environmental pollution is reduced; the alkaline soil conditioner can regulate and control the acid-base environment of soil and improve soil quality; and the alkaline soil conditioner improve physical and chemical properties of soil, can effectively reduce the number of pathogenic organisms, balanced microflora of soil and build a good root zone environment.

Description

technical field [0001] The invention belongs to the technical field of facility agriculture, and in particular relates to an alkaline soil conditioner and a preparation method thereof. Background technique [0002] The rapid development of facility agriculture in my country has reached 3.8 million hm 2 , and become the leading industry for farmers to increase their income. Due to people's pursuit of high economic benefits, coupled with planting experience and the drive of the market, the phenomenon of multi-crop continuous cropping cultivation per year is common, excessive emphasis on soil yield, excessive use of fertilizers and pesticides, and single crop cultivation are common. , the problem of soil degradation is becoming more and more prominent, mainly manifested as soil compaction and hardening, erosion, salinization, acidification, element imbalance, chemical pollution, loss of organic matter and degradation of flora and fauna, etc., seriously affecting the sustainabl...
