| 摘 要： | 提高作物对自然降水的利用效率是干旱半干旱区提高粮食产量、增强农田系统抵御干旱胁迫的主要途径之一。试验研究了在大田条件下陇中半干旱区小麦全膜覆土穴播栽培对土壤含水量、水分利用效率及产量的影响。结果表明:全膜覆土穴播处理的产量可达3518.61kg/hm2,比裸地提高29.13%,比传统地膜覆盖处理提高24.63%;水分利用效率为12.59kg/hm2.mm,比裸地提高19.90%,比传统地膜覆盖处理提高18.76%。全膜覆土穴播栽培技术能够显著提高小麦产量及水分利用效率,在小麦生育前期有效保持土壤水分,中后期可以将深层土壤(40～120cm)水分提到上层供小麦生长所需。

| Abstract: | To enhance the utilization efficiency of rainfall is one of the principal pathways of improving grain yieldand strengthening resistance of agricultural land system to drought stress in arid and semi-arid regions.The effects of film-mulched soil and bunch-seeded wheat in Gansu Longzhong semi-arid region on the soil moisture content,water use efficiency and grain yield were studied in the field.The results showed that the yield of bunch-seeded wheat in the film-mulched soil was 3518.61kg/hm2,29.13% higher tha... |
