Effects of Nutrient Solution Concentration on Photosynthesis Characteristics and Root Quality of Cucumber in Greenhouse
摘要
Abstract
[Objective]The aim as to study the effects of different nutrient solution concn. On fresh and dry weight of cucumber root in the whole growth period in the greenhouse so as to provide the reference for reasonable fertilization for greenhouse crop. [ Method] With the bagged perlite as the carrier of nutrient solution which used the Hoagland formula. 4 treatments for the diluting ratio of nutrient solution were set up as 1:200, 1:100, 1:50 and 1 :30 to study the effects of different treatments on photosynthesis characteristics and root quality of cucumber. [ Result] The photosynthesis characteristics and fresh and dry weight of cucumber root in the treatment for the ratio diluting of nutrient solution of 1:50 was higher than other treatments and the cucumber in this treatment could not be affected by the nutrient stress. [ Conclusion] The diluting ratio of nutrient solution of 1:50 was the optimum treating concn. For the soilless culture of cucumber in the greenhouse.关键词
