| 摘 要： | 严格用气象部门的观测方法，观测麦套春棉共生期间土壤温度的动态变化。结果表明：麦棉共生期由于小麦遮荫，使套种棉行的土壤温度低于纯作春棉，造成麦套春棉苗弱晚发。适当增大麦棉间距，选用株高较矮的小麦品种，可减少小麦对棉苗的遮荫，提高麦套春棉行间的土壤温度。

| Abstract: | Strictly using meteorological observation method, dynamic changes of soil temperature in wheat sping cotton relay cropping system during theirs common growth period were studied. Experimental results showed that soil temperautre in relay cropping cotton lines was lower than that in sole cropping cotton lines during their common growth period in wheat spring cotton, which made spring cotton seedling weak and developing slowly. The distance between rows of wheat cotton should be increased relatively. Soil temperature was highest. When chooseing relatively short wheat variety due to the reduction of the shade from wheat to cotton, and thus the soil temperature in wheat spring cotton relay cropping system is raised. |
