Soil water retaining agent

Abstract

A soil water retaining agent comprises the following raw materials by weight: 100-200 parts of hydroxyethyl acrylate, 200-320 parts of an alkaline solution, 50-160 parts of acrylamide, 1-3 parts of talcum powder, 3-6 parts of deionized water, 0.01-0.1 part of an initiator, and 0.1-0.3 part of a foaming agent. The soil water retaining agent of the invention is short in polymerization time, simple in process, good in water absorption stability, good in salt resistance, low in cost, and suitable for soil improvement and desert drought resistance, and can completely guarantee plant growth.

Description

Technical field: [0001] The invention belongs to a functional polymer material among polymer materials, in particular to a soil water-retaining agent. Background technique: [0002] Water retaining agent is a kind of polymer material, which has excellent water absorption and water retention performance. It can absorb water hundreds of times to thousands of times its own weight, and form certain pores in the soil to improve soil water retention and water permeability. The role of soil aggregate structure. Therefore, it is widely used in agriculture and forestry. The growth of plants not only needs water, but also depends on sunlight and nutrients. At present, water-retaining agents only have water-absorbing and water-retaining properties, and cannot provide other nutrients needed for plant growth, and cannot guarantee the normal growth of plants. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior ...
