本次试验主要研究了松原灌区苏打盐碱地改良适宜的灌溉洗盐定额,以及合理的冲洗次数和方法。通过开展灌溉冲洗的洗盐效果试验研究,提出了以建立起适合水稻生长的地表“淡化表层”[1]环境作为灌溉冲洗的控制标准,并制定了相应的灌溉洗盐定额。以便为松原灌区新垦盐碱地的大面积开发提供参考依据。
This experiment mainly studied the appropriate irrigating salt quota of soda saline-alkali land in Songyuan irrigation area, as well as the reasonable times and methods of irrigation. By carrying out experimental research on salt washing effect of irrigation flushing, a control standard of irrigation flushing was established based on the establishment of the surface “desalination surface” [1] environment suitable for rice growth and the corresponding irrigation salt washing quota was established. In order to provide reference for the large-scale development of reclamation saline-alkali land in Songyuan irrigation area.
