Abstract

The invention relates to a water-soluble polymer synergist used for fertilizers, its preparation method and application. The fertilizer synergist consists of 10%-20% (weight percent) of guar gum, 20%-30% (weight percent) of non-ionic polyacrylamide, 20%-30% (weight percent) of potassium polyacrylate, and 20%-30% (weight percent) of polysilicate potassium. The water-soluble polymer synergist of the invention can obviously increase the transmission speed and transmission distance of phosphorus in soil, reduce the fixation probability of phosphorus, enhance the water-retention property and fertilizer preserving property of soil, substantially increase crop yield, as well as effectively improve fertilizer utilization rate and reduce fertilizer usage.

Description

technical field [0001] The invention relates to a water-soluble polymer synergist, in particular to a synergist for chemical fertilizers and its preparation method and application. Background technique [0002] Phosphorus is one of the three elements nitrogen, phosphorus and potassium necessary for plant growth and development. After phosphate fertilizer is absorbed by plants, it participates in various forms of metabolic processes in plants, and is an indispensable component of nucleoproteins, phospholipids and phytochemicals. [0003] A large number of experimental results show that some soils have high phosphorus content, but the utilization rate of phosphorus by crops is very low, only 10-25%. The main reason is that phosphorus fertilizer has little mobility in the soil and is easy to be chemically fixed. The moving distance of phosphorus in the soil is generally 1-3cm, most of which are concentrated within 0.5cm around the fertilization point. Chinese patent CN1012893...
