【摘要】 以玉米为试材,采用新型高分子聚合物水溶性胶体对沙化地进行处理,对作物产量和沙地储水量进行研究。结果表明,播种前在沙地中施入高分子聚合物,可以有效的提高土壤的保水能力,改善作物的生长习性,减少耗水量,提高作物产量。加入225 kg/hm~2胶体时玉米折合产量达15 383.4 kg/hm~2,较不加胶体增产2 066.7 kg/hm~2,增产率15.52%;加入120 kg/hm2胶体时玉米折合产量14 083.4 kg/hm~2,较不加胶体增产766.7 kg/hm~2,增产率5.76%。更多还原

【Abstract】 In order to investigate the effect of water-soluble high-molecular polymer on water capacity and yield in maize on sandy land,we tested water capacity and yield by weighing method under different treatments. The result shows that there is higher water capacity under the treatment of adding water-soluble high-molecular polymer into sandy land at pre-sowing. There is 15 383.4kg/hm~2 yield under 225 kg/hm~2 treatment,this increased 2 066.7 kg/hm~2 yield than blank control,yield increasing percentage is15.52%. There is 14 083.4 kg/hm~2 yield under 120 kg/hm~2 treatment,this increased 766.7 kg/hm~2 yield than blank control,yield increasing percentage is 5.76%.更多还原
