旱地冬小麦膜侧宽幅匀播增产效应研究

小麦膜侧宽幅匀播技术是密植作物高产栽培新技术，其抗旱增产效果显著。为了给该技术在旱地小麦生产上的推广应用提供理论支持，以冬小麦普冰151为指示品种，采用田间小区试验，比较了冬小麦旱地膜侧宽幅匀播、膜侧沟播、常规条播三种不同种植模式的增产效应。结果表明，旱地膜侧宽幅匀播冬小麦产量极显著高于膜侧沟播和常规条播，折合产量为5 902.8 kg/hm2较对照的增产率为24.54%。表明冬小麦膜侧宽幅匀播集雨保墒效果好、抗旱作用显著，又利于密植和高产。

Study on Yield Increase Effect of Wide-width Uniform Sowing on the Film Side for Dryland Winter Wheat

The technology of wide-width uniform sowing on the film side of winter wheat is a new technology for high yield cultivation of close-growing crops which delivers significant effects on drought resistance and yield increase. In order to provide theoretical support for the promotion and application of this new technology in dryland wheat production, by using Pubing 151 as the material, a field plot experiment was conducted to compare the yield increase effects of three planting modes for dryland winter wheat, namely, wide-width uniform sowing on the film side, furrow sowing on the filmside and conventional strip sowing (the control). Results showed that winter wheat yield in wide-width uniform sowing on the film side was extremely significantly higher than those in other two modes, which had an average yield of 5 902.8 kg/ha and was 24.54% higher than that of the control. This indicates that wide-width uniform sowing on the film side for winter wheat has good rainwater harvesting and moisture conservation effects, which delivers significant drought resistance effect, and is ideal for dense planting and high yield cultivation.
