摘要:
根据长武旱塬长期定位试验研究，黄土旱塬区土壤中无机磷以Ca-P为主，占无机磷总量的70%以上，O-P占无机磷总量的9.19%，Al-P、Fe-P分别占无机磷总量的5.96%和5.23%.无机磷各组分中Ca2-P有效性最高，其次为Al-P、Fe-P、Ca8-P.长期施肥土壤剖面全磷、速效磷含量增加，无机磷各组分均有增加。化肥与有机肥配合能很好地促进无机磷各组分的有效性转化。
Abstract:
According to the study on long term experiments in Changwu dry highland, the highest availability of soil inorganic P is Ca2-P, then Al-P, Ca8-P, and Fe-P.The Ca-P, Al-P, Fe-P constituents would decrease on the condition of continuous cultivation without applying fertilizers.Yet, the O P constituents would increase.Contents of soil organic matter, total P, available P of different soil layers went up when continuous applying fertilizers, and all the constituents of soil inorganic phosphorus would either increase.
