摘  要:
在旱地条件下,设置不同种植密度来研究棉花群体质量的改善情况。结果表明,高密度(15×104株/hm2)群体可以通过增加覆盖率,减少土壤表面无效蒸发和增加植株叶片气孔阻力,减少植株叶面蒸腾来减少水分消耗;通过增加单位面积光合产物积累量和调节光合产物向库器官输出率来提高产量。通过以上两个方面提高土壤水分生产效率,建成旱地棉花高质量群体。

摘  要:
In dry land,various cotton planting densities were designed to study the improvement of cotton population quality. The result showed that for high population of cotton, the inefficient moisture evaporate at soil surface and moisture consume could be reduced by increasing mulched rate and increasing the stoma resistance in leaves to reduce the leaf transpiration. The yield could be increased by increasing photosynthate accumulation and adjusting the output rate of photosynthate toward fruit. The efficiency of soil moisture production could be increased by the above two methods to establish a cotton population of high quality in dry land.
