June 17, 2023 marked the 29th World Day to Combat Desertification and Drought. Currently, the basic situation where the area of desertified land in China is large, widely distributed, severely affected, and difficult to manage has not been fundamentally changed. The situation of desertification prevention and sand control remains severe. According to statistics, there are 3.861 billion mu of desertified land in China, accounting for approximately 27% of the country's total land area. Nearly 400 million people are affected by desertification. The prevention and control of desertification is urgent.

The agricultural and forestry water-retaining agent, known as the "micro reservoir of plants", is a soil water-retaining agent. It is an organic polymer with a unique three-dimensional network structure, which can repeatedly absorb and release water and continuously provide water for plants. It plays an important role in improving the ecological environment and windbreak and sand fixation projects, and is widely used in land desertification control, agricultural and forestry crop planting, and landscaping and greening.

Product Definition: Agricultural and Forestry Water Retention Agent is a soil conditioner used in agricultural and forestry production to improve the moisture properties of the soil around plant roots or seeds.

Product Appearance: Uniform powder or particles.

Main Raw Materials: The main raw material is a highly absorbent resin with extremely strong water absorption capacity. It can quickly absorb hundreds or even thousands of times its own weight of deionized water. After absorbing water, it expands into a water gel and then slowly releases water for seed germination and plant growth. Moreover, the raw materials of agricultural and forestry water retention agents should meet the requirements of agricultural products and environmental safety. The polymer resin components should be degradable and have been proven through experiments that the degradation products are safe for the soil and ecological environment. Common main raw materials of agricultural and forestry water retention agents include polyacrylate and polyacrylamide.
