棉茬晚播麦高产生长模式试验及其栽培技术

Patterns and technologies for high yield of delayed planting winter wheat after cotton harvested

  • 摘要: 通过对棉茬晚播麦进行多年试验测定和大面积调查,系统地研究了其群体结构及其对产量的影响,分析了不同产量麦田各生育期的叶面积延续时间(LAD)及干物质生产与分配。提出鲁西北地区棉茬晚播麦的高密度栽培技术及其配套品种和肥水管理措施,并研究了单项技术对晚播麦的增产效果。

     

    Abstract: After several years experiments and extensive investigations on late planted winter wheat after cotton harvested,the canopy structure and its influence on yield were analysed systemati-cally. The results showed that the optimum LAI was about 5.5 to 6.0 ,the vertical distribution of leaf area was uniform and most of the ears were from main stalk.The length of green leaf area extending period,dry matter production and partitioning condition were also analysed.Based on the results,and optimum pattern for high yield of the late planting winter wheat after cotton harvested was that high density of stalk,suitable varieties and appropriate fertilizer and water supply.
