保水剂是一种高分子吸水树脂,属高分子接技共聚物或淀粉交联产物,又名吸水剂、保湿剂。它具有优良的吸水、保水、吸肥、吸药特性。试验研究表明:保水剂在旱地作物的抗旱、节水栽培中的应用是一项费省效宏的栽培新技术。在早稻、玉米、棉花、红薯幼苗栽插中用保水剂蘸根,可以将土壤巾的水分吸收到根系周围,保持根部湿润的环境,达到天旱地不旱,保苗夺丰收的效果。 1、在早稻栽插上的应用。据试验,早稻栽插时用1％、2％、3％、4％、5％的水溶液蘸根处理,返青期分别是9、7、7、5、4天,比直接栽插不施保水剂的对照分别缩 Water-retaining agent is a polymer water-absorbing resin, a polymer graft copolymer or starch cross-linked product, also known as water-absorbing agent, humectant. It has excellent water absorption, water retention, fat absorption, absorption characteristics. Experimental studies have shown that: the application of water-retaining agent in drought-resistant and water-saving cultivation of dry land crops is a cost-effective new cultivation technique. In the early rice, corn, cotton, sweet potato seedlings planted with water retention agent dipped in roots, soil moisture can be absorbed into the roots around the root system to maintain the roots of the humid environment to reach drought drought is not dry, seedlings bumper harvest results. 1, in the early rice planting application. According to the experiment, early rice planting with 1%, 2%, 3%, 4%, 5% aqueous solution dipped root treatment, turning green period is 9,7,7,5,4 days than direct planting without water Control agents were reduced
