Inwheat intercropped with soybean not only N situation could be improved butalso P situation could be.2In intercropping,the pH of soybean rhizospherewas decreased by increasing the R-Apase activity,which could decelerate thetransforming and fixing P fertilizer.3In both monoculture and intercroppingsystem,the soil pH of rhizosphere was affected by cropping system at two Plevel which only 0.1-4mm distance from the root surface,but the effect of S-Apase activity in the rhizospher soil by cropping system was less than3mm.In effect,the rhizosphere P was really available nutrient,and applyingP to rhizosphere was effective ways to reduce the P nutrient competition.4Inwheat/soybean intercropping,the peak stage of reduction ability of roots wasthe same as that of the root growth,so that the time compensation appearedin intensity of nutrient absorption.

间套作大豆、小麦、玉米根系Apase的差异又反映出大豆利用土壤磷的潜在能力最大，而玉米最小，可见禾谷类的小麦与大豆间套后不但能改善小麦的氮素营养状况还使磷素营养也得以好转。2）间套大豆根际pH值的下降，导致磷肥施入土壤后形成〓-P的比例显著提高，转化成〓-P等难溶性磷减少，说明间套的大豆能减缓肥料磷在土壤中的转化和固定，减少磷素向无效化方向转化。3）复合群体根际土壤pH值的影响一般只发生在0.1-4mm的根际微区，而土壤磷酸酶的影响供磷与否在距根表3mm以外都无多大差异，说明根际磷才是真正有效磷，根际施磷是解决磷素竞争的有效途径。4）。
