不同栽培方式通过调控冬小麦的生长发育来影响冬小麦的产量。在这项研究中，对小麦的生长进行了两年的观察（2008年至2009年和2009年至2010年）。试验建立了3种栽培模式：25 cm齐行种植模式;“20 cm + 40 cm”宽窄行种植模式（宽窄行行距分别为40 cm和20 cm）;“20 cm + 40 cm”沟种模式（沟内双行，沟距20 cm，沟间40 cm，垄高15 cm）。建立了三个灌溉处理，即90、135和180 mm。结果表明，沟播提高了旗叶的荧光强度比值（Fv/Fm），随着灌水量的增加，Fv/Fm增大，增幅降低，旗叶净光合速率增加。但在规定的灌水范围外，这种效应并不明显。因此，考虑到该地区水资源短缺的情况，建议采用沟播模式，产量稳定，135 mm亏缺灌溉为最佳。2016年12月28日-Friends Science Publishers
Different cultivation patterns affect the grain yields of winter wheat by regulating growth and development. In this study, the growth of wheat was observed for two years (2008‒2009 and 2009‒2010). We established three cultivation patterns: 25 cm uniform row planting pattern; “20 cm + 40 cm” wide-narrow row planting pattern (wide-narrow row spacing is 40 cm and 20 cm respectively); and “20 cm + 40 cm” furrow planting pattern (double lines in the furrow with 20 cm spacing, 40 cm between furrows, and ridge height of 15 cm). Three irrigation treatments viz. 90, 135 and 180 mm were established. Results showed that furrow planting pattern improved the ratio of variable over maximum fluorescence (Fv/Fm).With increasing irrigation amount, Fv/Fm increased, the amplification declined, and the net photosynthetic rate in flag leaves increased. However, such effect was not obvious beyond the irrigation range stipulated. Therefore, we recommend the furrow planting pattern, which resulted in stable yield and 135 mm deficit irrigation as optimum considering the water shortage in the area. © 2016 Friends Science Publishers
