摘  要：
为了寻找马铃薯适宜的水肥管理模式,通过大田试验,以大水漫灌+肥料条施为对照(CK),研究了喷灌+肥料条施、滴灌+肥料条施和滴灌水肥一体化对马铃薯土壤酶活性及产量的影响。结果表明,与CK相比,滴灌水肥一体化、滴灌+肥料条施、喷灌+肥料条施处理均不同程度地提高了马铃薯土壤酶活性,其影响程度为滴灌水肥一体化>滴灌+肥料条施>喷灌+肥料条施,滴灌水肥一体化能够显著提高马铃薯生育后期的土壤酶活性。滴灌水肥一体化处理下马铃薯的产量和商品薯率最高,显著高于其他处理,其中,产量较CK及喷灌+肥料条施、滴灌+肥料条施处理分别提高49.07%及27.94%、14.91%,商品薯率较CK及喷灌+肥料条施、滴灌+肥料条施处理分别提高19.41个百分点及10.36、4.72个百分点。

摘  要：
In order to find the suitable water and fertilizer management mode for potato,the effects of sprinkler irrigation and fertilizer split application,drip irrigation and fertilizer split application,drip irrigation and integration of water and fertilizer on activity of soil enzyme and yield of potato were studied with flood irrigation and fertilizer split application as control(CK) through field experiment. The results showed that,compared with CK,drip irrigation and integration of water and fertilizer,drip irrigation and fertilizer split application,sprinkler irrigation and fertilizer split application increased soil enzyme activities; the order of influence degree was drip irrigation and integration of water and fertilizer > drip irrigation and fertilizer split application > sprinkler irrigation and fertilizer split application > CK,drip irrigation and integration of water and fertilizer could significantly improve the soil enzyme activity in the late growth stage. Finally,the potato yield and commodity rate of fertigation treatment was significantly higher than the other treatments,the yield increased by 49. 07%,27. 94%,14. 91%,commodity rate increased by19. 41,10. 36,4. 72 percentage points compared with CK,sprinkler irrigation and fertilizer split application,drip irrigation and fertilizer split application respectively.
