Soil amendment

Abstract

The invention relates to a soil amendment which is prepared from, by weight, 50-150 parts of fly ash, 100-200 parts of livestock manure, 100-200 parts of active sludge, 150-250 parts of leguminous green manure and 10-30 parts of mushroom bran. Compared with the prior art, the soil amendment has the advantages that soil aggregation is promoted, soil physical and chemical properties are improved, soil fertility is improved, and the yield of crops is increased.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improver. Background technique [0002] Soil is the material basis for the growth of crops. The amount of soil organic matter, the strength of soil fertility, the quality of soil aeration and the balance of soil solution play a decisive role in the growth of plants. In the long-term agricultural production, in order to meet the needs of the increasing population for food production, people use a large amount of arable land irrationally and use chemical fertilizers and pesticides unrestrainedly, which eventually lead to the deterioration of soil physical and chemical properties, the decrease of organic matter, the weakening of soil fertility, The consequences of poor soil aeration capacity and soil compaction seriously affect the normal growth of crops and the increase in yield; at the same time, there are also serious problems in agricultural production, such as l...

Problems solved by technology

In the long-term agricultural production, in order to meet the needs of the increasing population for food production, people use a large amount of arable land irrationally and use chemical fertilizers and pesticides unrestrainedly, which eventually lead to the deterioration of soil physical and chemical properties, the decrease of organic matter, the weakening of soil fertility, The consequences of poor soil aeration capacity and soil compaction seriously affect the normal growth of crops and the increase in yield; at the same time, there are also serious problems in agricultural production, such as low fertilizer utilization rate, and the deterioration of soil physical and chemical properties leads to leaching loss of fertilizer nutrients in the soil, etc. , the loss of fertilizer nutrients not only increases the cost of agricultural inputs, but also causes serious pollution to the environment, especially water resources that are already in short supply

[0003] In recent years, in order to improve the soil structure and soil fertility, a variety of soil improvers have appeared on the market. Some improvers have a long improvement cycle, and the continuous application time of the improver in practical applications is too short, so that the soil cannot be continuously improved. Cause improvement interruption and affect the improvement effect; some soil improvers, in order to increase the crop yield as soon as possible, add chemical fertilizers to the improver, in the long run, the soil will be further deteriorated while improving, and the improvement effect is poor; some improver components are complex , many production processes, high cost, and limited promotion; some improvers that use waste as raw materials have the advantages of environmental protection and low cost, but some improvers cannot be well coordinated between raw materials, and the ratio is unreasonable , causing further pollution and damage to the soil, affecting the normal growth of crops
