摘  要：
研究了宁南旱区坡耕地不同条带种植对谷子的产量、水分利用效率及旗叶光合特性的影响。结果表明:带状休闲轮种能增加谷子产量,提高其水分利用效率。条带种植处理Ⅰ、Ⅱ产量分别高出对照50.74、123.33 kg/hm2,差异极显著,水分生产效率分别比对照高0.10、.79 kg.hm-2.mm-1;条带休闲轮种可显著提高谷子叶片光合速率(Pn)和瞬时水分利用效率(WUEP),灌浆期条带种植处理Ⅰ、Ⅱ的Pn分别高出对照1.320、1.794μmol.m-2.s-1,WUEP比对照分别高1.31、1.03μmol.mmol-1。休闲轮种有利于增强谷子干物质积累能力,提高其群体水分利用效率。干物质积累量处理Ⅰ、Ⅱ拔节期显著高于对照,抽穗期、灌浆期和成熟期极显著高于对照。条带种植处理Ⅰ、Ⅱ主要生育期谷子群体水分利用效率(WUED)均显著高于对照。

摘  要：
Study on the effects of strip planting millet of yield and photosynthetic characteristics in sloping farmland in southern semi-arid area of Ningxia.The results showed that: the strip planting could increase millet yields,improve its water use efficiency(WUEY).The millet yield of strip planting treatmentⅠandⅡwere different from CK significantly,millet yield of treatmentⅠand Ⅱ were higher 50.74 kg·hm-2 and 123.33 kg·hm-2 than CK(1982.99 kg·hm-2),respectively,different significantly from CK,compared with CK,the millet WUEY of treatmentⅠand Ⅱ improved 0.1 kg·hm-2·mm-1 and 0.79 kg·hm-2·mm-1;The strip planting could improve the Pn and instantaneous water use efficiency(WUEP)of millet leaf significantly.In millet milking stage,the Pn of treatmentⅠandⅡwere higher 1.320 μmol·m-2·s-1 and 1.794 μmol·m-2·s-1 than CK,respectively,that were significant difference between CK,the WUEP of treatmentⅠand Ⅱwere significant higher 1.31 μmol·mmol-1 and 1.03 μmol·mmol-1 than CK,respectively;The strip planting was advantageous in Enhancing the ability of millet dry biomass,raising its water use efficiency at population level(WUED).The millet dry biomass of strip treatmentⅠand Ⅱwere weighter than CK significant in the Elongtion,and extremely significant from the heading to the maturity,the millet WUED had significant difference between the treatmentⅠ,Ⅱ and CK in main growth period.
