Sustainable development and governance
Lanyue continues to contribute to the health of the world's agriculture in terms of weight loss and efficiency, water conservation and soil fertility, labor saving and energy saving.
fertile ground for water conservation
Water retention agent is a highly absorbent resin that can absorb hundreds of times its own weight of water, and can be used as a miniature water reservoir in the soil, which can absorb water and reserve it when it encounters precipitation or irrigation, and then release water during the dry period, and these characteristics make it widely used in agriculture and forestry. These characteristics make it widely used in agriculture and forestry. It is of great significance to improve the physical properties of soil, enhance the soil's ability of water absorption, water retention and fertilizer retention, promote crop growth and development, alleviate the contradiction of China's water scarcity, improve the efficiency of water and fertilizer use, and promote the development of dry farming.
We innovate and develop new multifunctional water retaining agents to solve the problems of traditional polyacrylic acid-acrylamide, polyacrylic acid-starch, polyacrylic acid-cyclodextrin and other types of water retaining agents that are difficult to be degraded or have limited fertilizer retention capacity.
The multifunctional water retaining agent and the preparation method have the following advantages:
① Introducing Pullulan polysaccharide into the structure of water retaining agent makes the water retaining agent obtain good biodegradability and improve water retention;
② Introducing β-cyclodextrin structure through maleic anhydride β-cyclodextrin monomer, using the special molecular cavity structure of cyclodextrin to improve the water retaining agent with good fertilizer retaining effect;
③ In the late stage of polymerization reaction, adding dried powder of Bacillus sphaericus, and then drying and crushing improved the effect of Bacillus sphaericus and made the water retaining agent obtain physiological efficacy, compared with the way of grinding powder of the water retaining agent and then mixing it with powder of the bacterium, which saved energy, simplified the process, and reduced dust pollution, and made the water retaining agent absorb and swell to become gel, and the bacterium body can be kept in the gel body to enhance the role of slow-release, and improved the final Effect.
