Problems solved by technology

The traditional method of acidic soil improvement is to use lime or limestone powder alone. The application of lime can obviously reduce the acidity of acidic soil, but sometimes it will strengthen the degree of reacidification
There are also some acidic soil compound improvers on the market, the main component is a mixture of lime and certain minerals or industrial by-products, but most of these improvers contain a certain amount of toxic metal elements, such as lead, cadmium, arsenic, chromium, etc. , there is a problem of pollution to the soil environment,
[0003] In the prior art, CN 103444294 A discloses a method for improving acidic soil. Although the method is easy to obtain raw materials and low in cost, it needs to consume a large amount of calcium salt or alkali, and the soil improvement effect is general; CN 103694028A discloses a An improvement agent for acidic soils, however, due to its complex composition, it is not suitable for large-scale promotion

Abstract

The invention discloses an acid soil conditioner. The acid soil conditioner is mainly prepared from components in parts by weight as follows: 30-50 parts of leguminous crop straw powder, 10-25 parts of seaweed meal, 6-12 parts of a calcium fertilizer, 1-10 parts of a macromolecular compound, 5-15 parts of molasses and 8-20 parts of poultry faces. The acid soil conditioner is mainly prepared from leguminous crop straw and natural seaweed, the raw materials are widely sourced, pure natural and non-pollution, waste straw is turned into wealth, the soil structure is improved while waste resources are fully used to realize environmental protection, the water and fertility retention capacity of soil is improved, the yield of crops is increased, the quality is improved, the preparation process is simple, and the cost is low.

Description

technical field [0001] The invention relates to the field of agricultural technology, and relates to a soil conditioner, in particular to an acidic soil conditioner and a preparation method thereof. Background technique [0002] Soil improvement is the process of taking corresponding physical, biological or chemical measures to improve soil properties, soil fertility, crop production, and the soil environment for human survival against the poor texture and structure of the soil. Soil acidification is a manifestation of soil degradation, which refers to a natural phenomenon in which soil acidification increases and becomes strongly acidic or extremely acidic. Soil acidification in my country is becoming more and more serious, and the acidified land area has expanded to more than 35% of the cultivated land area in my country, and it often occurs in patches, especially in southern my country. The acidification phenomenon is more serious, and the soil acidification or severe aci...
