摘要
在相同灌溉水量条件下,以不同比例混合塔里木盆地干旱区地下咸水(3.56 g/L)和地表淡水(0.4 g/L),采用膜下滴灌技术充分灌溉,探求棉花在微咸水膜下滴灌条件下的耗水规律。经研究表明以处理3的矿化度为分界线,表现出棉花耗水规律受水盐协迫不同因素的影响。
This test irrigation water under the same conditions, different combinations of the Tarim Basin in Arid Areas saline groundwater （3.56 g/L） and surface fresh water （0. 4 g/L） are used with full irrigation, drip irrigation with mulch technology, the micro-salt water drip irrigation under mulch conditions of water law research is explored. The study indicates that a deal with three of the mineralization as a dividing line. It also shows that cotton is subjected to different water and salt water laws.
