应用多聚体土壤结构改良剂,如聚丙烯酰胺、多糖与再生改良剂和多聚体凝胶等,是一项农业新技术。它的作用是:增加土壤的孔隙;增加水分的渗透性;防止土壤结皮;减小土壤冲刷和水分迳流;土壤松散易于耕作;降雨或灌溉后,土壤干得快,可以立刻下地耕作。由此产生效益有:作物根系发达,生长快而健壮;种子
Applications Polymer soil structure modifiers, such as polyacrylamide, polysaccharides and regeneration improvers, and polymer gels, are new agricultural technologies. Its role is to increase soil porosity, increase water permeability, prevent soil crusting, reduce soil erosion and water runoff, allow soil to be loosely tillage, and allow soil to dry quickly after rainfall or irrigation. The resulting benefits include: crop root system developed fast and robust growth; seeds
