磷酸酶的活性与有机质、全P和速效P都呈正相关,但与有机质的相关性不显著;
Soil available P was not affected by nematodes, while soil microbial biomass P increased obviously with the inoculation of nematodes.接种线虫对土壤有效p的提高不明显,而对土壤生物量P有显著的增加。
The increase in available P due to P fertilizer application and the yearly decrease in available P after pot culture varied greatly with soil types.施磷肥处理所增加的有效磷比例和盆栽后土壤有效磷量逐年下降幅度因土壤类型不同而差异很大。
