摘要
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 test mainly research the appropriate irrigation quota to wash the salt in the saline-alkali soil improvement of Songyuan irrigation district,and a reasonable number of washing and methods.Through irrigation water to wash salt trial research,It proposed to establish a suitable suriace of the rice-growingcalled ＂di- lute surface＂ environment as irrigation water control standards ,and to develop appropriate irrigation quota to wash the salt.It provides a reference for the development of a large area in Songyuan Irrigation district.
