摘要
重盐碱区种植棉花须用水压盐碱。在膜下滴灌条件下,如何才能在盐碱地上高产、高效植棉是至关重要的问题。通过试验,为此,探索出一套在重盐碱地上采用膜下滴灌种植棉花的技术措施,并进行了经济效益比较分析。
How to achieve cotton yield increase and to gain higher economic effects in heavy saline-alkaline fields, when applying the technology of drop-irrigation under plastic films to cotton growing? On the basis of experiments, this paper puts forward to a list of concrete technical measures and makes economic effects analysis.
