Effects of Different Nitrogen-form on the Photosynthesis and Fruit Quality of Cucumber

Abstract

Abstract: With the facility experiments,it was investigated that the influence on chlorophyll of cucumber,photosynthesis and fruit quality on different ratios of ammonium-N and nitrate-N.Resuhs showed as follows：in the same treatment,different leaves’SPAD was significant,flower leaves affected SPAD very much,fruit leaves less,and early flower leaves the least.Different nitrate-N and ammonium-N combined,with the increase of nitrate-N,SPAD of the flower leaves,fruit leaves,early flower leaves increased.In general,different fertilizer ratio was not significant.Appropilate fertilizer level Was helpful to improve the efficiency of light conversion,and could enhance the plants photosynthesis.The net photosynthesis rate,Cond,Ci,the transpiration rate had the same changing rule on cucumber：flower leaves was the greatest,fruit leaves Was the second,early leaves was the last.When the ratio of the nitrate-N and ani· monium-N is 1：1,the nitrate and organic acidcontent was lower,VC content was higher,quality was better yield was higher.

Key words: Ammonium nitrogen, Nitrate nitrogen, Cucumber, Photosynthesis, SPAD
