| 摘 要： | 以中低产田为对照，采用化学分析，顿号生物试验和统计分析相结合的方法，研究了山东省主要土类高产农田的土壤养分状况、磷素组成与其有效性。结果表明：夏玉米的产量受土壤有效磷含量的制约；土壤缓效磷、有效磷含量和供磷强度是评价高产农田土壤肥力特征的重要标志之一；高产田中Ｃａ２－Ｐ，Ａｌ－Ｐ，Ｆｅ－Ｐ，Ｃａ８－Ｐ，ＬＯＰ均高于中低产田且与土壤有效磷含量和作物吸收的磷量呈显著相关；棕壤、褐土的供磷状况优于潮土，

| Abstract: | The respective strength of available P, slow-releasing P and supplying P in high-yield soil is higher than that in lower-yield soil. The amount of available P in soil conditions the yield of summer corn. 2. Ca,-P, Al-P , Fe-P, Ca8-P and Lop,which are closely related with the amount of P absorbed by wheat, have been proved to be important sources of available P in soil. The total amount of Al -P and Fe- P in Brown earth and cinnamon soil is higher than that of cultivated meadow, in which although there is a high content of supplying P, the main component of inorganic P is only Ca10- P. |
