| 摘 要： | 以辽宁沈阳市郊某设施菜地土壤为研究对象,通过设置不同有机肥用量处理(0,20,60thm-2)的小区实验,系统研究不同有机肥处理对不同本底肥力设施菜地土壤全磷、速效磷含量变化的影响。研究结果表明,有机肥能够提高不同肥力设施菜地土壤0～20cm土层全磷含量,其中P1全磷含量与CK相比增加2.7～19.5%,P2增加7.6～33.6%。土壤0～20cm速效磷含量也随有机肥施用量的增加而明显增加,P2即有机肥施用量60thm-2时,不同肥力设施菜地土壤在黄瓜拉秧期速效磷含量与CK、P1之间均达显著差异(P<0.05)。本实验条件下,施用有机肥20thm-2,可保持施肥当季中肥力与高肥力设施菜地土壤磷素水平;当地常规有机肥施用量60thm-2可显著提高设施菜地土壤全磷与速效磷含量,从而加剧高肥力土壤磷素的累积,并对环境造成压力。

| Abstract: | A field plot experiment was conducted in Shenyang suburb to study the effects of applying organic manure on the status of phosphorus in greenhouse soils.Three treatments(0,20,and 60 t hm-1 of organic manure) were installed in greenhouse fields with different soil fertility levels.The results showed that the contents of total P,available P in 0-20 cm soil layer increased with applying organic manure,being significant when the application rate was 60 t hm-1,while that in 20-40 cm soil layer had no significant... |
