Fertilizer for conditioning acid soil

Abstract

The invention belongs to the technical field of fertilizers, and particularly discloses an organic fertilizer for conditioning acid soil. The organic fertilizer comprises pig manure, pine bark, bark of myrica rubra, coconut shell powder, buckwheat husk, medical stone, soy source residues and compound biological bacteria. The organic fertilizer has the advantages that acid-alkali neutralization reaction can be carried out on the organic fertilizer and acid in the soil, accordingly, the purpose of treating the acid can be effectively achieved, the quality of the soil can be comprehensively improved, the fertility of the soil can be improved, water and fertilizers can be reserved, and the utilization rate of the organic fertilizer can be increased; the content of beneficial bacteria in the soil can be increased under the key effects of microorganisms in the organic fertilizer, the soil can be activated, diversified nutrient elements and diversified physiological active substances can be provided for crops, and synthesis of nutrient substances of the crops can be promoted; the already acidified soil with deteriorated quality can be effectively improved after the organic fertilizer is used for a long term, accordingly, comprehensive balance nutrients can be provided for the crops, the disease resistance and the stress resistance of the crops can be greatly improved, the organic fertilizer is quick and lasting in fertilizer efficiency, fertilizer damage can be prevented, the yield can be effectively increased, and the cost can be effectively saved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a fertilizer for conditioning acid soil. Background technique [0002] There has always been a large area of ​​acidic soil in the south of the Yangtze River in my country. At present, the soil acidification in a large area in the south of the Yellow River is also becoming more and more serious. The former is formed by the acidic parent material of the soil and the rainy climate, and the latter is mainly caused by the application of nitrogen and phosphate fertilizers. ; Soil acidification and low pH value not only directly affect the nutrient absorption function of plant roots, hinder the growth and development of plants, but also affect the decline of soil organism activity. [0003] (1) Causes of soil acidification: 1. Large amount of fertilizer application and small rainwater leaching; 2. Excessive application of acidic fertilizer; 3. Large amount of nitrogen fertilizer appl...

[0004] (2) Harmful effects of soil acidity: 1. Some plants cannot grow well under low acidity conditions; 2. Reduce the activity of nitrogen-fixing bacteria in the soil, bacteria that convert ammonium into nitrate nitrogen, and bacteria that decompose organic matter. 3. Make elements such as aluminum and manganese more soluble, causing them to be toxic to plants; 4. Make phosphorus and molybdenum nutrients insoluble and become ineffective phosphorus and molybdenum; 5. Acidic Loss of nutrients calcium and magnesium in the soil

[0005] (3) Improvement of the current acidic soil: the current improvement of the acidic soil is to apply calcium carbonate powder (limestone powder) or quicklime (calcium oxide) to the soil, so that the acid in the soil and calcium carbonate powder (limestone powder) or quicklime (oxidized lime) Calcium) undergoes an acid-base neutralization reaction to achieve the purpose of reducing soil acidity and increasing soil pH; its disadvantages are: 1. The effect is simple, it can only reduce soil acidity and increase the content of soil improvement element calcium; 2. The use of quicklime powder is easy to cause damage to the human body, especially to the eyes
