匀播滴灌对小麦分蘖消长规律及产量三要素的影响

Influence of Uniform Sowing and Drip Irrigation on the Rule of Tillering and Three Factors of Wheat Yield

针对宁夏水资源匮乏、水分管理不合理和春小麦分蘖成穗率较低等小麦生产现状,将滴灌水肥一体化和匀播栽培技术相结合,开展了不同播种方式和灌溉方式试验,研究了匀播和滴灌对春小麦分蘖消长规律及产量三要素的影响。结果表明:匀播和滴灌技术均促进了小麦的分蘖,较条播漫灌多0.5~1.2个,其中匀播的分蘖成穗率在15%左右,而统计显示条播的分蘖成穗率成负值;产量三要素方面表现为匀播滴灌处理收获穗最高,较其他处理多8%~16.7%,穗粒数也最高,较其他处理多3~8个。

In this experiment,Ningxia water scarcity,water management is not reasonable and spring wheat tillering rate low status,the fertigation and uniform sowing technique combined test was carried out in different planting patterns and irrigation methods,studied the effect of uniform seeding and drip irrigation on growth and yield of spring wheat tillering three elements. The results show that the uniform seeding and drip irrigation could promote wheat tillering,more than the flood irrigation with drilling seeding 0. 5-1. 2,which was the uniform seeding of spike rate at around 15%,while the drilling show a tiller rate of negative; The yield of the uniform seeding and drip irrigation is highest,compared to others 8-16. 7%,The grain number of the uniform seeding and drip irrigation was the highest,3-8 more than other treatments.
