| 摘 要： | 在新疆南疆自然生态条件下,研究了杏棉间作对棉花产量及其构成因素的影响.结果表明:间作棉花的LAI在整个生育期低于单作,且峰值出现早,后期下降缓慢,比单作低15.9%;叶片的净光合速率Pn与SPAD值联系密切,盛花期前叶片的Pn、SPAD值增长快,间作的叶片Pn和SPAD值均低于单作;间作棉花地上部干物质快速积累持续期比...

| Abstract: | Under the natural environment in south Xinjiang,we studied the effect of apricot-cotton intercropping on cotton yield and yield components,aimed at providing the theoretical basis for efficient cultivation technology of cotton in the apricot-cotton intercropping system.The results showed: The LAI of intercropped cotton was lower than that of sole cotton through the whole growth stage,and the peak of LAI appeared earlier and LAI of intercropped cotton decreased slowly at the later stage,and was lower than th... |
