Abstract:
Taking‘Sino dutch No.10’cucumber as material,application effect of NPK fertilizer on winter greenhouse cucumber was analyzed by using‘3414’test design scheme.The results showed that with the increasing of N,P,K fertilizer application,cucumber yield showed a trend of initial increasing and then decreasing,in line with the fertilizer law of diminishing returns,the yield increasing effect of fertilizer was N>P2O5>K2O;and the positive interaction effect were NP,NK,while the PK for reverse interaction effect,the maximum yield of N∶P2O5∶K2O of matching ratio was 424.32∶251.01∶219.03,the maximum yield was 57 038.23 kg/hm2,the best combining ratio of planting benefit was 388.16∶248.25∶159.15,and the best planting benefit was 128 215.27 yuan/hm2 under the combining ratio;the yield was higher in the complete fertilizer area.and there was no significant difference between the high N,P,K area,and the ratio of output to input was relatively higher,it was the optimal treatment combination.
