Abstract The composition of invented nutrition fixed water consists of (wt.%) acrylic acid 0.53%, sodium hydroxide (30%) 0.929%, deionized water 0.54%, N,N'-methylene biacrylic amide 0.0005%, ammonium persulfate 0.0005%, nutrient solution 98%. According to the above ratio, acrylic acid and deionized water are put into reactor and neutralized with sodium hydroxide, then raise temperature to 40 deg.C, add N,N'-methylene biacrylic amide, stir for 0.5hr, add ammonium persulfate, polymerized at 50 deg.C for 3hr., a colloidal lump is obtained which is pelletized by granulator. The resin pellet is immersed into the nutrient solution, after absorbing and saturating with water, it is dried to the end product. The effect of utilization is 10-20 times to the direct irrigation of water by same weight. It is widely used for afforestation on the desert and mountain.
