日光温室土壤磷素组成变化及有效性研究
|
摘要
为了解日光温室土壤磷素形态组成变化规律及其有效性,测定了日光温室土壤P素含量和形态组成,结果表明:日光温室土壤磷素形态组成和比例与粮田土壤比较发生明显改变,土壤无机P含量由粮田土壤的Ca10-P> Ca8-P> Al-P>Fe-P> O-P> Ca2-P变化为温室土壤Ca8-P> Ca10-P> Al-P> Ca2-P> Fe-P> O-P。日光温室土壤与粮田土壤磷素各组分有效性顺序比较几乎没有变化,都为Ca2-P> Al-P> Ca8-P> Fe-P> Ca10-P> O-P。
To understand the composition of greenhouse variation of soil phosphorus forms and the effectiveness of greenhouse soil P measured pigment content and form composition. the results show that: Greenhouse Soil Phosphorus soil composition and proportion of grain compared with the apparent change in soil inorganic P content in grain of soil from theCa10-P > Ca8-P > Al-P > Fe-P > O-P > Ca2-P changes in the greenhouse soilCa8-P > Ca10-P> Al-P > Ca2-P > Fe-P > O-P. Greenhouse soil grain of soil phosphorus availability compared with almost no changes have to: Ca2-P > Al-P > Ca10-P > Ca8-P > Fe-P > O-P.
