相关研究表明,用光合速率可以较好地模拟测算作物经济产量。为全面快捷高效地筛选出更高效更适合南疆推广的枣棉间作棉花种植模式,以不同的行间距并结合差异化灌水对枣棉间作环境下的棉花进行处理,以此产生的不同光热环境为基础,建立叶片水平的净光合速率分析图。利用净光合速率折线图,结合使用棉花整个生长季实测的叶片相关生理数据,对所建图示进行比较。结果发现,M3(距红枣行0.5 m种植棉花,枣行间种6行棉花)、W3(按350 m3·667m-2灌水)处理的净光合速率与大田棉花的净光合速率相似度最高。两者相交,M3W3处理的净光合速率平均值也最大,最终产量也最高,符合实验设想。由本试验结果可以看出,利用净光合速率能提前预计作物的经济产量,节约研究时间,在枣棉间作种植生产中,可以筛选出更好的棉花种植模式。
相關研究錶明,用光閤速率可以較好地模擬測算作物經濟產量。為全麵快捷高效地篩選齣更高效更適閤南疆推廣的棘棉間作棉花種植模式,以不同的行間距併結閤差異化灌水對棘棉間作環境下的棉花進行處理,以此產生的不同光熱環境為基礎,建立葉片水平的淨光閤速率分析圖。利用淨光閤速率摺線圖,結閤使用棉花整箇生長季實測的葉片相關生理數據,對所建圖示進行比較。結果髮現,M3(距紅棘行0.5 m種植棉花,棘行間種6行棉花)、W3(按350 m3·667m-2灌水)處理的淨光閤速率與大田棉花的淨光閤速率相似度最高。兩者相交,M3W3處理的淨光閤速率平均值也最大,最終產量也最高,符閤實驗設想。由本試驗結果可以看齣,利用淨光閤速率能提前預計作物的經濟產量,節約研究時間,在棘棉間作種植生產中,可以篩選齣更好的棉花種植模式。

Related studies showed that the photosynthetic rate could be used to simulate the economic output of crops .In order to select highly efficient and suitable planting mode of cotton in intercropping with jujube in south Xin-jiang ,the experiment was conducted with different row spacing and different irrigation quota for cotton in jujube/cotton intercropping system .The net photosynthetic rate ( Pn ) of cotton leaves under different light and thermal environments was analyzed ,and other related physiological parameters were also measured ,so as to compare them with each other by drawing broken line figures .The results showed that ,under the treatments of M3 (6 rows of cotton in each strip ,and 0 .5 m of spacing between jujube and cotton ) and W3 (irrigation quota:350 m3 ·667m-2 ) ,the Pn of cotton was most similar to that of sole-cropping cotton ;under the combined treatment of M3W3 ,the average Pn of cotton was the largest , and the yield was the highest .Therefore , Pn can be used for predicting the economic yield of cotton and for selecting the planting mode of cotton in jujube/cotton intercropping system .
