Multifunctional acid soil conditioner and application method thereof

Abstract

The invention discloses a multifunctional acid soil conditioner and an application method thereof. The multifunctional acid soil conditioner is prepared by mixing 10 to 25 percent of magnesium hydroxide, 15 to 30 percent of calcium carbonate, 5 to 25 percent of calcium hydroxide, 10 to 25 percent of calcium magnesium phosphate fertilizer, 0 to 15 percent of lime nitrogen, 0 to 30 percent of lignite, 0 to 30 percent of danty, 0 to 30 percent of peat, 0 to 2 percent of borax and 0 to 3 percent of zinc sulfate in percentage by weight, and stirring uniformly. For solving the series of problems that southern soil is serious in acidification, degenerate in structure and frequent in soil-borne disease, on the basis of combining a great amount of field trial results, an acid soil conditioner formula having the functions of providing nutrition, improving the soil, killing the soil-borne disease and the like is developed, and meanwhile a certain amount of medium trace elements and synergists are added in the formula, so that the formula can meet the need of plants on medium trace nutrient elements in a growth development process, so as to remarkably improve the yield and quality of crops.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a multifunctional acidic soil conditioner and an application method thereof. Background technique [0002] Soil acidification is one of the main problems restricting the sustainable development of agriculture in China. The area of ​​various types of acidified soil in China is about 200 million hm 2 . In recent years, with the continuous increase of acid rain deposition and the extensive use of ammonium nitrogen fertilizers, soil acidification has intensified. The proportion of soil acidification area in the cultivated land area in my country is increasing. In 2009, the soil acidification area has reached more than 40% of the cultivated land area, and the average annual growth rate is 3.1%. Soil acidification in my country mainly occurs in acidic soils in the south, namely red and yellow soils. Most of these acidic soils have pH<5.5, and most of them have pH&...

AI Technical Summary

Problems solved by technology

However, some studies have shown that a large amount or long-term application of lime will not only cause soil compaction and form "lime board field", but also easily cause the imbalance of calcium, potassium, magnesium and other elements in the soil, resulting in crop yield reduction

In addition, after traditional amendments are applied to the soil, they only change the local soil acidity, and the soil quickly becomes acidic after a period of cultivation, and the improvement effect lasts for a short time
