Abstract:
With greenhouse soil that continuous cropped with different plant as test object,by target yield method，the method of balanced fertilization of nitrogen，phosphorus and potassium on nutrition richness soil in greenhouse were studied.The results showed that under nutrition richness soil in greenhouse，nitrogen，phosphorus and potassium of the cucumber yield were 29.3%,-9.6%，35.4%；nitrogen，phosphorus and potassium of the tomato yield were 32.6%,30.69%，56.99%；nitrogen，phosphorus and potassium recovery rate of the bean yield were -2.4%,-35.8%,-7.97%.In this experiment，the maximum nitrogen and potassium application rate of cucumber，tomato and bean per 667 m2 were 32.1,27.0,17.4 kg,the fixed N/K ratio of cucumber，tomato and bean were 1.4∶1,1.4∶1,1∶1.Expanding balanced fertilization technique of nutrition richness soil could improve the yield，saving fertilizer and increase economic benefits.
