Soil water-retaining agent and preparation method thereof

Abstract

The invention relates to an agricultural fertilizer, and particularly relates to a soil water-retaining agent and a preparation method thereof. The soil water-retaining agent of the invention comprises the following components by mass: 5 g-10 g of ammonium hydrogen phosphate; 1 g-3 g of magnesium sulfate; 5 g-10 g of diatomite; 5 g-10 g of vulcanic ash; 1 g-2 g of sodium polyacrylate; 10 g-15 g of urea; 0.5 g-1 g of auxin; 30 g-50 g of straw slag; and 5 g-10 g of zeolite. The soil water-retaining agent of the invention has excellent water-storing and water-retaining performance, can effectively improve the water utilization rate of soil, is added with auxin for assistant promotion of plant growth, and effectively solves the problems of soil water depletion and water shortage in drought areas.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a soil water-retaining agent and a preparation method thereof. Background technique [0002] With the increasing environmental pollution and the decrease of green vegetation year by year, it poses a severe test to the human living environment, especially in the fields of agricultural production and urban greening, where the water in the soil is easy to lose, causing soil agglomeration, soil desertification and other problems , so how to quickly absorb and retain rainwater or irrigation water in the soil without seepage, and then ensure sufficient water g in the rhizosphere and release it slowly for plants to use has become an important research direction. [0003] Most of the existing fertilizers only add a variety of nutrients, and pay less attention to the water content of plant roots. Water is one of the important factors to promote the growth of crops. How to solve the problem of...
