【摘要】 利用高吸水树脂抗旱保肥特性 ,采用恒温箱实验室试验、田间小区试验和大田推广相结合的方法 ,确定了不同生态气候条件下高吸水树脂玉米抗旱栽培的方法 ,解决了玉米抗旱适时播种和移栽。通过多种试验 ,研究了高吸水树脂对玉米根系生长、出苗率、成活率、叶片光合效率、经济性状、产量结果的关系 ,确定了吸水树脂对幼苗根系生长有促进作用 ,明显增强了种子抗旱能力 ;玉米的出苗率、移栽成活率分别比对照提高 4.1 0 %～ 5.2 0 %和1 3.8%～ 1 6.0 % ;增产率为 5.0 %～ 2 0 .0 %更多还原

【Abstract】 Using the absorptive resin’s property of resisting drought and holding fertilizer, we have defined the way of using the absorptive resin in planting maize under different climate by means of examination. And we have succeeded in sowing and transplanting maize in proper time. Also this paper studies the relation of the absorptive resin sousing method and the maize’s root growth, the emergent rate, the economic properties and the yield .It is demonstrated that the absorptive resin can promote growth of younger roots of maize, and raise the ability of maize seed’s resistance to drought. As compared with CK, the emergent rate of maize’s seedling has increased by 4.1%～ 5.2%, the survival rate of transplant has also increased by 3.8%～16.0%. And it made the yield increased by 5.0%~20.0% as compared with CK.更多还原
