Effects of Irrigation Lower Limit and Grafting Methods on Root Growth and Water Use Efficiency of Cucumber in Greenhouse
Abstract：With the cucumber as the experimental materials, the small area trial was conducted to study the effect of different control of irrigation lower limit on root distribution, yield, quality, and water use efficiency of self-rooted cucumber, single-rooted grafting cucumber and double-rooted grafting cucumber under plastic film mulch irrigation in the greenhouse. The results showed that grafting and reducing irrigation lower limit increased total root length, there was no significant difference in the effect of different treatments on quality of cucumber, and under the 85 % irrigation lower limit, the yield and water use effi- ciency of double-rooted grafting cucumber improved respectively 17% and 17% compared with self-rooted cucumber.
