【摘要】 不断改进节水灌溉的优化模式提高产量降低成本,提高科学用水内涵不断挖掘节水增产潜力,对提高有限水的利用效率十分重要。采用科学的节水灌溉方法;根据不同植物不同的需水临界期;优化耕作制度,选用节水抗旱植物品种等措施,则可以起到显著的节水增产效果,那么在现有的水库存水数量基础上可以扩大灌溉面积50%,甚至增加1倍以上。粮食单产可翻几番,达到节水高产少种多收。更多还原

【Abstract】 It is very important for raising limited water use efficiency to advance optimal model of water-saving so as to improve yields and reduce costs,enhance scientific water using connotation so as to tap water-saving and production-increasing potentials.The effect of water-saving and production-increasing will be notable after adopting scientific water-saving irrigation technique,optimizing cultivation system according to different plants’ different critical period of water requirement and choosing water-saving drought control plant variety.Then irrigation area will be extended to 50%,even more one time,on the base of the volume of water in current reservoir.And the single yield of foodstuff can rise several times so as to gain water-saving,high yield,grow little and receive more.更多还原
