匀播、滴灌对春小麦幼穗分化进程及产量的影响

The Effects of Uniform Sowing and Drip Irrigation on the Spike Differentiation and Yield of Spring Wheat

为进一步挖掘宁夏春小麦增产节本潜力,针对宁夏水资源匮乏、春小麦产量不高、水分管理不合理和灌水量较大等突出问题,以优化水分管理和提高水分利用效率为目标,开展了春小麦滴灌、匀播试验。以宁春50为试验材料,采用二因素完全随机区组设计,分析匀播、滴灌技术对春小麦幼穗分化进程及产量的影响。结果表明:匀播、滴灌技术均增加了小麦幼穗分化持续时间;产量表现为匀播滴灌(YD)处理较匀播漫灌(YM)处理增产17.3%,YD、条播滴灌(TD)处理较条播漫灌(对照)分别增产17.1%和14.1%。

Lack of water resources in Ningxia has led to poor yield of the spring wheat due to unreasonable water management such as large amount of irrigation. To increase the potential of the spring wheat yield in Ningxia and lower the cost at the same time, optimizing water management by improving water use efficiency were carried out in our study. Combined with advanced drip irrigation technology and homogenization technology, the experiment on different sowing methods and irrigation methods was conducted. Ningchun 50 was used as the test material in this experiment and a two-factor complete random block design was used. Effects of uniform sowing and drip irrigation on spike differentiation and yield of spring wheat showed that： The yield performance was 17.3% higher than that of YD, Treatment of YD and treatment of TD were 17.1% and 14.1%, respectively.
