Abstract
A field plot experiment was conducted in Shenyang suburb to study the effects of applying organic manure on the phosphorus accumulation and its availability in greenhouse soil and the yield of cucumber. Five treatments (0, 10, 20, 40, and 60 t hm -2 of organic manure) were installed. The results showed that, after harvest, the total P content in 0～20 cm soil layer increased with increasing application rate of manure, being more significant when the application rate was 40 t·hm-1, while that in 20～40 cm soil layer had no significant difference among the treatments. Under the application of organic manure, the available P content in 0～20cm soil layer increased before the stage of flowering and decreased then, while that in 20～40 cm soil layer increased gradually from the beginning to fruiting stage. In our study, applying 20 t·hm-2of organic manure could maintain the soil available P level, while higher application rates could induce the risk of soil P leaching. Appropriate application rate (10～40 t·hm-2) of organic manure could improve cucumber yield, but the yield was not increased significantly with excessive rate (40 t·hm-2) of organic manure.
