    摘要:

    磷肥在我国的施用,不問北方的石灰性土壤或长江流域的土壤,解放前和解放初期所进行的試驗和調查总結,都表明过磷酸鈣的肥效不一致,反应显著的不多.但是,近年各地試驗結果表明,磷肥肥效有逐漸显著的趋势.

    Abstract:

    According to the results obtained from field experiments laid on phosphatic fertilizer and from the fractionation of soil phosphorus,the writers classified the important soil types of Kiangsu Province into three groups:(1) Soils rich in phosphatic nutrients gave no response to superphosphate by all crops.Soils of this type include neutral grey-brown loamy clay derived from Hsiashu loam of Nanking district,calcareous sandy loam derived from alluvial deposits of lower Yangtze plain and neutral clayly paddy soil from lacustsine deposits of Su-Chou district.
