| 摘 要： | 对长期轮作连作条件下的大豆、玉米、小麦土壤磷组分进行研究,试验结果表明,供试土壤在不施肥情况下,土壤全磷以轮作区降幅最大,而土壤有效磷以小麦连作区降幅最大,土壤磷组分以大豆连作区土壤中的Ca2-P降幅最大;在施有机肥的情况下,土壤全磷以大豆连作区增幅最大,而土壤有效磷以轮作区增幅最小,土壤磷组分以轮作土壤中的Ca2-P增幅最大。

| Abstract: | In this paper, the phosphorus forms were studied in soybean ,maize and wheat soil under long-term crop rotation and continuous cropping. The results indicated that under no fertilization condition, the decreasing range of total phosphorus in rotation is largest, but that of available phosphorus in continuous cropping wheat soil is largest, that of Ca2-P in continuous cropping soybean soil is largest. Under applying manure condition, the increasing range of total phosphorus in continuous cropping soybean soil is largest, but that of available phosphorus in rotation is smallest, that of Ca2-P in rotation soil is largest. |
