Problems solved by technology

[0002] The input of fertilizer plays a vital role in the yield of crops, but in the actual planting process of crops, there have been problems of single and excessive fertilization for a long time, and the average utilization rate of fertilizers is very low. The main reason is that the quick-acting fertilizers volatile and volatile
The corresponding measures are to use slow-release coated fertilizers to improve the utilization rate of nutrients, but the strength of the single-layer coating is low, the proportion of slow-release nutrients is fixed, untargeted, and the demand for nutrients restricts its own development.

Abstract

The invention discloses liquid-state controlled release fertilizer used for improving content of calcium in soil and belongs to the field of fertilizer. The liquid-state controlled release fertilizer used for improving the content of calcium in soil comprises 34-38% of washing water of rice, 15-19% of ammonia water, 4.2-6.2% of sodium alginate, 7-9% of chitosan, 20-22% of a controlled release microbial agent, 1-1.6% of a controlled release microelement chelating agent and 10.8-12.2% of controlled release microcrystalline calcium mineral powder. The liquid-state controlled release fertilizer used for improving the content of calcium in the soil has the characteristics that the fast-acting property and loss of the fertilizer can be reduced while the fertilizer utilization efficiency is guaranteed, balance between fertilizer supply and fertilizer demand is achieved, and physical and chemical properties of planting soil are improved.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a liquid slow and controlled release fertilizer for increasing the calcium content of soil. Background technique [0002] The input of fertilizer plays a vital role in the yield of crops, but in the actual planting process of crops, there have been problems of single and excessive fertilization for a long time, and the average utilization rate of fertilizers is very low. The main reason is that the quick-acting fertilizers Sexuality and volatility. The corresponding measures are to use slow-release coated fertilizers to improve nutrient utilization, but the strength of the single-layer coating is low, the proportion of slow-release nutrients is fixed, and there is no specificity. The demand for nutrients restricts its own development. Contents of the invention [0003] The purpose of the present invention is to: aim at the above-mentioned problems, to provide a liquid slow-release fertilizer, w...
