Organic compound soil modifier and preparation thereof

Abstract

The invention relates to a soil modifier, in particular to a organic compound soil modifier and a preparation thereof, and the compound soil modifier comprises the following raw materials by parts by weight: 100-200 parts of organic matters, 20-40 parts of porous inorganic matters, 30-60 parts of clay, 100-150 parts of strong acid, 60-100 parts of compound fertilizer or urea, 40-70 parts of clay, 0.5-2 parts of microbial agent and 0.03-0.1 part of yeast. The compound soil modifier can significantly improve the soil physical and chemical properties, improve the content of the organic matters in the soil, promote the soil aggregate formation, have a porous structure, effectively prevent the loss of nutrients, promote the crop growth, improve the utilization efficiency of the fertilizer and the like, further utilize the renewable resource, realize small environmental risk and have excellent ecological and economic benefits.

Description

technical field [0001] The invention relates to a soil conditioner, in particular to an organic composite soil conditioner and its preparation. Background technique [0002] 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, nutrient balance imbalance, soil fertility decline, resistance The ability of natural disasters is poor, which seriously affects the normal growth of crops and the increase of yield; at the same time, there is still a serious problem of low fertilizer utilization rate in agricultural production. The deterioration of soil physical and chemical properties has brought about problems such as leaching loss of fertilizer nutrients in the soil. The loss of fertilizer nutrients not only increases the...

Problems solved by technology

[0002]In the long-term agricultural production, in order to meet the needs of the increasing population for food production, a large number of irrational use of cultivated land and unrestrained use of chemical fertilizers and pesticides, these ultimately It has led to the deterioration of soil physical and chemical properties, imbalance of nutrients, decline of soil fertility, poor ability to resist natural disasters, seriously affecting the normal growth of crops and increasing yield; at the same time, there are still serious problems of low fertilizer utilization in agricultural production

The deterioration of soil physical and chemical properties brings about leaching loss of fertilizer nutrients in the soil. The loss of fertilizer nutrients not only increases the cost of agricultural input, but also causes serious pollution to the environment, especially the water resources that are already in short supply.
