摘要
针对新疆膜下滴灌改良盐碱地中存在的毛管布置对土壤水盐分布影响规律问题,通过田间对比试验不同毛管布置形式下棉花膜下滴灌水盐分布特点的初步探讨研究,以期为膜下滴灌改良盐碱地提供理论基础。结果表明,一管两行的布置方式无论在水分分布还是盐分分布都较一管四行有利于作物生长与盐碱地改良,但是,在生产实际中,农民多采用一管四行的布置方式,因此从盐碱地改良与提高作物产量等综合因素考虑上还有待研究确定综合效益最优的毛管布置方式。
In order to improve saline alkali soil by drip irrigation for cotton under plastic mulch in Xinjiang,the field control experiments with dif ferent capillary layouts are made to find out water and salt law issues. The results show that the layout of a-capillary-with- two line has advan tage over the one of a-eapillary-with-fou-line in salt or water distribution, which is conducive to crop growth and saline-alkali soil improvement. In actual situation,farmers often use the layout of a-capillary-witln four-line, so from the aspect of the saline-alkali soil improvement and in creased crop yields, the comprehensive study needs to be determined on the overall efficiency of the optimal layout of the capillary.
