【摘要】 试验研究表明番茄膜下滴灌比沟灌节水,增产省工,膜下滴灌仅为沟灌用水量的75%,增产36.8%。膜下滴灌可使作物根系层的水分条件始终处在最优状态下,同时能够保持土壤具有良好的透气性,能调节土壤水、气、热,有利于作物生长发育,使作物缓苗快,上市早、品质高。膜下滴灌能改变农田生态环境,使番茄病毒危害减轻,是增产,增值的防止病害的有效途径,其经济效益显著。更多还原

【Abstract】 This study indicate drip irrigation for tomato under mulch is better than furrow irrigation ones for such kind of method needs less water and has higher production.Drip irrigation only needs 75% water of furrow irrigation,but with production increased by(36.8%.) Drip irrigation make the soil have upstanding breathe freely character.It can adjust the soil,air and hot,which is benefit for the grow of plants and tomato can ripe early and has good quantity.Drip irrigation can change the living environment of soil,reduce the hurt of pests and poisions.It is an effective way of increase production and prevent pests,which has an obvious economic interest.更多还原
