Based on field experiment in sunlight greenhouse on Loess Plateau

this paper dealt with the continuous cropping obstacle of cucumber. The results showed that

as continuous cropping years increasing

soil main fertility index increased

but the ratio of N

P and K was not rationale. As continuous cropping years increasing

soil bacteria and epiphyte quantity increased obviously

but fugue not increased

cucumber main disease become serious. There were significant difference in growth characteristics and productivity in continuous cropping years.
