Embodiment 1

[0038] Embodiment 1: the preparation of acidic soil conditioning agent The content of each component of acidic soil conditioning agent is: quicklime 24kg, rice husk charcoal powder 42kg, attapulgite 6kg, calcium magnesium phosphate fertilizer 6Kg, silicon fertilizer 6kg, pig manure organic fertilizer 7kg, Peat 6kg, K 2 HPO 4 3kg.

[0039] The preparation steps of acidic soil conditioner are as follows:

[0040] (1) Crush the pig manure organic fertilizer and peat and pass it through a 40-80 mesh sieve to remove larger particles, and set aside;

[0041] (2) Combine calcium magnesium phosphate fertilizer, sieved pig manure organic fertilizer with K 2 HPO 4 Mix well and set aside;

[0042] (3) Mix sieved peat, silicon fertilizer, attapulgite, straw charcoal powder and quicklime to obtain a mixture, add 20% to 50% of water, stir and mix repeatedly, so that the temperature of the mixture reaches above 100°C, and Activate the activity of mineral silicon, enhance the mechanica...

Abstract

The invention relates to an acid soil conditioner. The acid soil conditioner is prepared from, by weight, 20-40 parts of quick lime, 25-45 parts of straw charcoal powder, 5-15 parts of attapulgite, 5-15 parts of calcium magnesium phosphate fertilizer, 5-15 parts of silicon fertilizer, 5-15 parts of pig manure organic fertilizer, 5-15 parts of turf and 1-10 parts of K2HOP4. The invention further relates to a preparation method and application of the acid soil conditioner. The low-cost raw materials are combined according to a specific ratio, a use method is easy and convenient, the soil pH can be adjusted, nutritional elements needed by plants are added while the pH adjusting and heavy metal adsorption capacity is guaranteed, soil organic matter can be increased, formation of the soil granular structure can be promoted, the permeability of soil can be enhanced, plant growth can be promoted, and the risk of soil caking caused by application of a soil conditioner can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural environment conservation and restoration, in particular to an acidic soil conditioner and its preparation method and application. Background technique [0002] Soil acidification is a manifestation of soil degradation. Soil acidification is not only an important reason for the decline of soil fertility, but also an important factor restricting the sustainable development of agricultural production. According to statistics, from the 1980s to the present, my country's soil acidification has become more and more serious, and the acidified land area has expanded to more than 40% of my country's cultivated land area, and often occurs in large areas, especially in southern my country. The soil itself is slightly acidic, and there is more rainfall, which makes the soil acidification more serious. [0003] Soil acidification can cause the activation of heavy metals such as aluminum, manganese, chromi...
