Acidified soil conditioner

Abstract

The invention discloses an acidified soil conditioner, which is prepared from the following materials in parts by weight: 10 to 20 parts of soybean meal, 15 to 30 parts of humic acid, 8 to 15 parts ofmanure, 5 to 17 parts of crop straws, 3 to 10 parts of corn flour, 3 to 5 parts of polyacrylamide, 3 to 8 parts of wheat bran, 5 to 25 parts of rape seed cakes, 10 to 30 parts of bentonite, 8 to 25 parts of plant ash, 1.3 to 2.3 parts of biological bacterial agent, 3 to 9 parts of mushroom residue and 3 to 15 parts of tea production waste. The conditioner prepared by the invention can effectivelydecrease soil acidity and exchangeable aluminum content, and moreover, the acidified soil conditioner contains a lot of organic matters and trace elements to improve soil structure, increase the dietary fiber activity of crops and improve the taste of agricultural products. According to the invention, the material sources are wide, the method is simple and feasible, wastes are turned into treasure, and the acidified soil conditioner has the advantages of high effectiveness, low cost and low toxicity, and can improve the problem of soil acidification after being used for a long term.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an acidified soil improver. Background technique [0002] my country has a large population base and a small area of ​​arable land per capita. There is a long-term huge pressure to ensure food security, and the intensity of soil utilization is much higher than that of other countries. With the rapid development of economy and society, soil degradation problems such as acidification, salinization, element imbalance, loss and pollution have become increasingly prominent, seriously restricting the development of land productivity. Soil acidification refers to the reduction of H in soil under natural and artificial conditions. + The decrease of soil pH value caused by the increase of concentration is one of the important indicators of land productivity and an important form of soil degradation. Soil acidification accelerates the increase of soil acidity, which will lead to...

Problems solved by technology

[0004] The prior art, such as the Chinese invention patent application publication number CN 107033922 A, discloses a soil conditioner and its preparation method, using bentonite, zeolite powder, plant straw, soybean meal, waste tobacco ashes, polyacrylamide, boric acid, Humic acid, chitosan, potassium sulfate and mixed strains are used as raw materials to prepare soil conditioner through microbial fermentation. The soil conditioner produced by this method has certain effects in improving soil acidification and salinization, but zeolite powder accumulates in a large amount in the soil It will cause the loss of ammonium nitrogen, and the use of potassium sulfate and boric acid will lead to re-acidification of the soil, so it is not suitable for long-term use
