在垄作覆膜条件下进行不同滴灌量及滴灌次数试验,研究马铃薯适宜滴灌量和滴灌次数的优化灌溉模式,结果表明:优化出3种最佳滴灌方案,分别为滴灌定额15m3/667m2,分5次滴灌;滴灌定额25m3/667m2,分5次滴灌;35m3/667m2,分4次滴灌;比未滴灌马铃薯鲜薯增产45.60%～82.43%,水分利用效率提高34.6%～53.52%,可供生产上根据窖蓄水量状况推广应用。
Under the condition of ridge film mulching, different drip irrigation and drip irrigation times were carried out to study the optimal irrigation pattern of suitable potato drip irrigation and drip irrigation times. The results showed that three kinds of optimum drip irrigation schemes were optimized, namely drip irrigation quota 15m3 / 667m2, Drip irrigation; drip irrigation quota 25m3 / 667m2, drip irrigation 5 times; 35m3 / 667m2 drip irrigation 4 times; than non-drip irrigation potato yield 45.60% ~ 82.43%, water use efficiency increased 34.6% -53.52%, for production According to the status of reservoir storage capacity to promote the application.
