Abstract
Some basic properties of several kinds of high water absorbing resins(HWAR)includingProduct made in our laboratory,and HSPAN from market were studied by means of incubation,laboratory incubation and pot experiment respectively. The results show that millet seed coatedwith the resin germinated l to 1.5 days earlier than control one. Seeding rate and surviving ratewas increased by 4%～16%and 9%～15%individually,ratio of root to seeding by 0.30 to 1.13times. Besides,with soil application of the resin,the water-stable aggregates of 2～1,1～0.5,0.50～0.25mm were 12.91,10.67,7.64 times and 52.30, 19.53,12.03 times of control in thetreatment of soil application of 0.75%HSPAN and the resin self made separately. Soil appliedthe resin had a great capability to resist water erosion being more than 72%of the soil coltimnnot dispersion compared with only smaller than 6%of that of the control experiment.Soil appli-cation of HWAR is not only increase the amount of total soil water,but raise thc easily availablewater content by 4.84%and 8.16%for the treat of HSPAN and the resin self made individuailyas well.
