Silkworm excrement and shell ecologic acidic soil conditioner and preparation method thereof

Abstract

The invention discloses a silkworm excrement and shell ecologic acidic soil conditioner and a preparation method thereof, and belongs to the technical field of agriculture soil fertilizers. The silkworm excrement and shell ecologic acidic soil conditioner is prepared from, by weight, 20-90 parts of shells and 10-80 parts of silkworm excrement. Synergism of shell powder and silkworm excrement after the shell powder and the silkworm excrement are mixed, co-fermented and combined is found in the invention, so the utilization of calcium in the shell powder by the acidic soil is greatly improved, the soil acidity improvement effect of the conditioner is substantially better than the total acidity improvement effect reached by individual use of the silkworm excrement and the shell powder; and the conditioner disclosed in the invention improves the acidic soil improving effect of the silkworm excrement and the shell powder, improves the absorption of nutrition in the silkworm excrement and shells by crops, and increases the output of crops.

Description

technical field [0001] The invention relates to a soil conditioner and a preparation method, in particular to a silkworm excrement shell ecological acidic soil conditioner and a preparation method, belonging to the technical field of agricultural soil fertilizers. Background technique [0002] Acidic soil has the following main hazards to the production of crops: 1. When the pH value of the soil is low, the activity of heavy metals will increase exponentially, which will easily cause the poisoning of heavy metals such as aluminum, iron and manganese to crops, and affect the normal growth of crops. 2. The pH value of the soil is low, and the nutrient phosphorus in the soil is easily fixed by the highly active aluminum and iron, so that the phosphorus in the soil is converted into fixed phosphorus, which makes the crops unable to absorb it. 3. The soil is acidic and has weak adsorption capacity for cations, resulting in K + , Ca 2+ , Mg 2+ Mineral nutrients such as ions are...

Problems solved by technology

[0002] Acidic soil has the following main hazards to the production of crops: 1. When the pH value of the soil is low, the activity of heavy metals will increase exponentially, which will easily cause the poisoning of heavy metals such as aluminum, iron and manganese in crops, and affect the normal growth of crops.

2. The pH value of the soil is low, and the nutrient phosphorus in the soil is easily fixed by aluminum and iron with high activity, so that the phosphorus in the soil is converted into fixed phosphorus, which makes it impossible for crops to absorb

3. The soil is acidic and has weak adsorption capacity for cations, resulting in K + , Ca 2+ , Mg 2+ Mineral nutrients such as ions are easily leached, resulting in a lack of mineral nutrients such as potassium, calcium, and magnesium in acidic soils

The Chinese invention patent with the patent application number 201410333583.X discloses a multifunctional ecological acidic soil conditioner, which is prepared from raw materials such as silkworm excrement, tobacco stems, bovine bone meal, and sodium alginate, which can increase soil pH and improve The content of organic matter in the soil can avoid underground pests and improve soil fertility, but there are problems of high raw material costs and slow reduction of soil acidity
