Abstract:
Taking cucumber as material，the effects of different growing seasons on yield，the law of nutrient absorption，and fertilizer use efficiency and agronomic efficiency under greenhouse condition were studied.The results showed that compared with the farmer practice fertilizer (FP),optimum fertilizer（OPT）was much higher，there were not significant differences of cucumber yield under different growing seasons.From the economic point of view，due to low inputs of optimum fertilizer (OPT) the cost of the cucumber plant was reduced，its economic benefit was remarkable higher than that of FP.Because FP treatment applied high application rate of phosphoric fertilizer，and lead to cucumber on phosphorus accumulation quantity was higher，but the agronomy efficiency of nitrogen fertilizer and fertilizer utilization rate were low；potassium in the winter and spring cucumber crop of facilities was the main limiting factors，followed by the phosphorus，the smallest，the influence of nitrogen spring and the crop of the cucumber，nitrogen was the main limiting factors.
