Embodiment 1

[0018] A kind of soil remediation agent, comprises calcium cyanamide 72.5kg, medium and trace element fertilizer 25kg, beneficial bacterium 2.5kg, beneficial bacterium is the EM bacterium that buys in Henan Zhengzhou Baiyibao Biotechnology Co., Ltd., and the effective bacterium of described beneficial bacterium Content ≥ 200 million CFU / mL, the beneficial bacteria are sealed in capsules, the weight content of each component of the medium and trace element fertilizer: 15 parts of organic matter, 10 parts of chelated zinc, 10 parts of chelated iron, 10 parts of chelated magnesium , 1 part of chelated copper, 1.5 parts of organic nitrogen, phosphorus, and potassium.

[0019] Apply the soil remediation agent prepared in this example to the soil with a pH value of 5.5, and the usage rate per mu is 100 kg. After two consecutive planting seasons, the measured soil pH value is increased to 6.1; the chelated medium and trace elements fully supplement the soil nutrients , to balance the...

Abstract

The invention discloses a soil repair agent and a preparation method thereof. The soil repair agent comprises the following components in parts by weight: 10-80 parts of calcium cyanamide, 10-70 parts of a medium trace element fertilizer and 1-20 parts of beneficial bacteria, wherein the beneficial bacteria are sealed into capsules; corresponding parts of components are evenly mixed to obtain the soil repair agent. By adopting the soil repair agent disclosed by the invention, the soil pH value is adjusted, malignant bacteria and nematodes in the soil are killed, the soil-borne disease is reduced, the soil environment is repaired, the functions of the soil environment are restored, and especially, a series of vicious circles caused by soil environment degradation can be effectively contained. The soil repair agent is convenient to use, all components can be received by the soil, the soil repair agent is an ideal multifunctional soil environment repair agent with the functions of fertilization and fertility increase, slow release and nitrogen fixation, soil and water conservation, acid-base adjustment, bacterial inhibition and disease control and low price. The soil repair agent is less in equipment investment, simple in preparation process and low in manufacturing cost.

Description

technical field [0001] The invention relates to the fields of agriculture, soil conditioners and fertilizers, in particular to a soil repair agent and a preparation method thereof. Background technique [0002] About 50% of the soil in my country has many problems such as acidification, lack of trace elements, imbalance of flora, salinization, compaction, heavy metal pollution, lack of organic matter, obstacles to continuous cropping, etc., which seriously affect the yield and quality of crops, and some even fail to harvest. In particular, soil acidification, lack of trace elements, and imbalance of bacterial flora are the three major problems currently restricting China's agriculture from becoming high-quality and high-yield. At present, the national soil acidity and alkalinity (pH value) has dropped by an average of 0.9 units in 30 years, and the area of ​​acidic cultivated land (pH<5.5) has increased from 7% 30 years ago to 35% at present. Soil pH is critical for plan...
