本研究系统地阐述了麦后移栽棉的生长发育特性,从光能利用、营养代谢、物质积累与分配等方面,探讨了麦后移栽棉的生理特性,揭示了麦后移栽棉开花结铃规律。首先提出麦后移栽棉的光能利用为“高效型”,营养代谢为“旺盛型”;生长发育为“快速型”;开花结铃呈“集中型”。该研究在南京进行,本区光温资源优于沿海棉区,表明在热量资源丰富的江苏沿江、黑下河棉区,只要栽培措施得当,麦后移栽棉的产量水平可以达到麦套移栽棉水平。
The research systematically expounded the growth and development characteristics of transplanted cotton after transplanting wheat. The physiological characteristics of transplanted cotton after transplanting wheat were discussed from aspects of light energy utilization, nutrient metabolism, material accumulation and distribution, Knot the law. The paper first proposed that the light energy utilization of transplanted cotton after transplanting was “high efficiency type” and nutrition metabolism was “exuberant type”; the growth and development was “rapid type”; The study was conducted in Nanjing. The light and temperature resources in this area are superior to those in the coastal cotton area. It shows that the yield of transplanted cotton after wheat transplanting can reach the level of wheat translocation as long as the cultivation measures are properly taken in the rivers and streams of Jiangsu and Heihe Rivers where the caloric resources are abundant Cotton planting level.
