【摘要】 超吸水剂在国外已广泛应用于工业、农林业和医疗卫生。近年来,我国也有不少同类产品问世,但在农业上应用较少。本文通过室内模拟等试验,说明HL型超吸水剂不仅可以提高土壤保水保肥性能,还能改善土壤结构,可以作为土壤改良剂。用于蔬菜育苗,对提高秧苗的素质具有良好的影响。但是要达到生产上普遍应用,还须不断降低它的价格,并加强使用方法等研究。更多还原

【Abstract】 Super moisture absorbent is a macromolecular compound. It can absorb several hundred times its weight of water. As a new type of material, it has been widely applied abroad to industry, agriculture, forestry, medical and health work, and so on. Recently, some super moisture absorbents have also been produced in our country, but as yet are less applied to agriculture. The results of simulation experiment in laboratory showed that after the application of HL type super moisture absorbent to soil, the water and fertilizer retention ability of soil would be obviously raised and the structure of soil would also be improved. Therefore, it is a good soil-improving agent. In addition, it also is a good material for growing seedling. In order to widely extend the application of HL type super moisture absorbent to agriculture, it is necessary to reduce production costs and to strengthen research on application method更多还原
