Abstract
Effects of different N,P and K application on cucumber yield and quality in sunlight greenhouse were studied.Results showed that the increased ratio of phosphorus fertilizer could improve cucumber yields significantly.Proper N,K and more P application improved soluble protein content in fruit.Proper N-P fertilizer combined with more K fertilizer improved fruit quality,increased the content of soluble sugar and vitamin C,and decreased the content of NO3-.
