垄作行间非等量播种技术对小麦生长发育及产量的影响

Effect of Non-equivalent Sowing Technique on Wheat Growth and Yield in Raised-bed-planting Model

在垄作模式下,通过对边行和内行设置不同的密度水平,研究了不同模式垄作小麦的生态效应和生长发育状况。结果表明,不同垄作模式对小麦群体的影响不同,其中,采用非等量播种技术且边行较内行播量多30%的T5处理的群体结构最为合理,个体和群体生产力得以协调发展,旗叶光合速率、叶绿素含量等光合生理指标表现较好,产量最高。

In raised-bed planting condition,the ecological indicators and growth status of winter wheat were studied by setting up different density levels between border row and inner row.The result showed that different bed-planting models had different effects on the growth and development of wheat.The T5 treatment had the most rational population structure and the highest yield because of its harmonious development between the population and the individuals and its better physiological indexes such as the flag-leaf photosynthetic rate and chlorophyll content.
