Abstract

The invention relates to a soil conditioner comprising the following components in percentage by weight: 10-30% of yellow phosphorus slag, 3-20% of humic acid, 6-12% of nitrogen-fixing bacteria and a culture medium thereof, 6-12% of cellulose decomposition bacteria and the culture medium thereof, 3-6% of vermiculite, 2-5% of limestone, 6-10% of perlite, and the balance of a filling material. According to the invention, the pH value is adjusted to 9-11. The soil conditioner disclosed by the invention can be used for effectively improving a crop failure phenomenon caused by soil blocks with serious hardening and significantly-decreased fertility, and has the advantages of low cost, high speed and the like, and is simple to operate.

Description

technical field [0001] The invention belongs to the field of soil improvement, and relates to a soil improvement composition and a method for soil improvement. Background technique [0002] Due to the long-term use of chemical fertilizers, some farmlands have been severely hardened, and soil fertility has declined year after year. In some areas, due to long-term unreasonable cultivation, the acid-base structure of the soil has been seriously damaged. These factors have a negative impact on agricultural production. In view of this situation, the soil Carry out artificial improvement, by taking corresponding physical or chemical measures, improve soil properties, increase soil fertility, increase crop yield, and achieve the purpose of improving the soil environment for human survival. Soil improvement work is generally based on the natural and economic conditions of each place, formulates feasible plans according to local conditions, and implements them gradually to achieve th...
