Soil organic-inorganic conditioner for reclamation of waste residential land and preparation method of soil organic-inorganic improver

Abstract

The invention discloses a soil conditioner for reclamation of a waste residential land. The soil conditioner comprises fly ash, livestock manure and ferrous sulfate. The application amount of the coalash is 20-25 t / hm<2>, the application amount of the livestock manure is 13.5-16.5 t / hm<2>, and the application amount of the ferrous sulfate is 0.2-0.25 t / hm<2>. The livestock manure is chicken manure. The invention also discloses a preparation method of the soil conditioner for reclamation of the waste residential land. The method comprises the following steps: 1, uniformly mixing the fly ash, the livestock manure and the ferrous sulfate in proportion, and adding a leavening agent to obtain a mixture; and 2, performing composting, turning and ventilating oxygen supply treatment on the mixture obtained in the step 1 to obtain the soil conditioner. According to the soil organic-inorganic soil conditioner for reclamation of the waste residential land and the using method, the physical and chemical properties of the soil are improved, great convenience is brought to later cultivation, and the crop yield is increased.

Description

technical field [0001] The invention relates to the technical field of raw soil maturation, in particular to a soil organic-inorganic modifier for reclamation of abandoned homesteads and a preparation method thereof. Background technique [0002] The soil of recultivated land mainly comes from the raw adobe walls and rammed earth walls of abandoned houses. Because the wall materials are hard into large blocks, it is difficult to break, and as the main body of the building is exposed to the air, affected by different climates and human factors, physical The structural condition is extremely poor, lack of permeability, poor soil nutrients, lack of microbial system in the soil, lack of inherent functions and characteristics of the soil, it is difficult to be directly used for agricultural cultivation after reclamation, and cannot meet the needs of crop growth, so it is necessary to reclaim the soil Make improvements to make it mature quickly and continuously, and restore the ba...
