| 摘 要： | 对林业苗圃地连作、轮作条件下土壤磷组分进行了3a的研究,结果表明,在同等施肥情况下,连作培育杉木苗、酸枣苗、厚朴苗以及杉木与酸枣、厚朴轮作土壤全磷基本不变,而杉木连作土壤有效磷降幅最大.连作土壤中土壤无机磷组分O-P、Al-P、Fe-P略有增加,轮作土壤略有降低.连作土壤有机磷组分略有降低,轮作土壤略有增加.由于施用了有机肥,杉木与烟草、水稻、萝卜轮作土壤有机磷组分增幅较大,O-P、Al-P、Fe-P组分则有不同程度的降低.

| Abstract: | This paper was dealt with the influences of continuous cropping and rotations on soil phosphorus forms in forest nursery for three years.The results indicated that under the same fertilization condition,the total phosphorus concentrations of soils from the site of cultivating Cunninghamia lanceolata,Choerospondias axillaris and Magnolia officinalis in continuous cropping were roughly no changing,however,the available phosphorus of the soils were decreased,especially from the cultivating Cunninghamia lanceolata in continuous cropping.The contents of O-P,Al-P,and Fe-P were increased slightly in continuous cropping soils,but decreased slightly in rotations soils.The contents of organic phosphorus forms in continuous cropping soils were decreased slightly,and those in rotations soils were increased slightly.Because of applying organic manure,the contents of organic phosphorus forms were increased significantly,in rotation soils of Chinese fir and tobacco,rice,and radish,respectively,while the contents of O-P,A-P,and Fe-P were decreased in different levels in those soils. |
