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 some 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

Abstract

The invention discloses an acidic soil modifier and a preparation method thereof. The soil modifier is composed of the following raw materials in parts by weight: 35 to 45 parts of fly ash, 14 to 19 parts of active carbon, 12 to 22 parts of plant ash, 15 to 25 parts of calcium superphosphate, 10 to 19 parts of apatite powder, 20 to 35 parts of potassium nitrate, 19 to 22 parts of lime powder, 30 to 45 parts of bean pod shell powder, 25 to 45 parts of active sludge, 25 to 45 parts of bamboo charcoal, 15 to 25 parts of sea mud, 30 to 50 parts of polyacrylamide, 15 to 25 parts of sawdust, 13 to 15 parts of sphagnum moss, and the balance being deionized water. The raw material sources are wide, the raw materials are natural and pollution free, the waste straws are converted into valuable resources, the wastes are fully utilized, the environment is protected, the soil structure is improved, the fertilizer and water retaining performance of the soil is balanced, and the quality and output of crops are both improved.

Description

technical field [0001] The invention relates to an acidic soil improver 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 acidification is about 90% or more. The traditional method of improving acidic soil is to use l...
