中科院兰州化物所研制出一种新型抗旱保水剂一水解淀粉聚丙烯晴树脂(LSA)。目前正由西化油漆厂投入批量生产。这种保水剂能快速吸收几百倍乃至上千倍于自身重量的水,具备优良的保水性。随着植物生长和根部周围水分的变化,它可以缓慢地将水分释放出来,供植物生长之用,可称为土壤中的“蓄水池”。由于它内部有氮元素,对植物生长也有利。
Lanzhou Institute of Physics, Chinese Academy of Sciences has developed a new type of drought-resistant water-retaining agent, a hydrolyzed starch polypropylene resin (LSA). Westernization paint factory is currently put into mass production. This water retention agent can quickly absorb hundreds of times or even thousands of times its own weight of water, with excellent water retention. As plants grow and the water around the roots changes, it slowly releases water for plant growth and can be called a “reservoir” in the soil. Because of its internal nitrogen, the plant is also beneficial to the growth.
