在甘肃引黄灌区的灌耕灰钙土区域，通过玉米／鹰嘴豆间作种植，采用蒋柏藩、顾益初石灰性土壤无机磷分级方法研究了施磷水平和间作种植方式对玉米、鹰嘴豆土壤无机磷素形态的影响。结果表明：研究区各无机磷形态含量顺序为O－P＞Ca10－P＞Ca8－P＞Al－P＞Fe－P＞Ca2－P ，施磷能够显著提高玉米和鹰嘴豆土壤中Ca2－P、Ca8－P、Al－P和Fe－P的含量，O－P和Ca10－P的含量不随施磷量增加发生显著性变化；与单作相比，间作种植对鹰嘴豆土壤带各无机磷组分含量没有显著影响，但间作玉米种植带土壤各组分无机磷含量均低于单作土壤，其中不施磷肥处理下Fe－P、施纯磷40 kg·hm－2处理下Al－P及施纯磷80 kg·hm－2处理下Ca10－P的含量显著低于单作土壤。

The dosage effects of phosphorous applications on yield of maize and chick-pea under mono-cropping and intercropping systems were investigated using Jiang-Gu inorganic phosphorus fractionation method in irrigated sierozems in Gansu Yellow River Irrigation District .The results showed that the contents of inorganic phosphorus were in the following order:O-P>Ca10 -P>Ca8 -P>Al-P>Fe-P>Ca2 -P .With the increased uses of phosphate fertilizer ,the con-tents of Ca2 -P ,Ca8 -P ,Al-P ,and Fe-P had increased significantly ,whereas the contents of O-P and Ca10 -P did not show apparent changes .The inorganic P contents looked similar between mono-cropped and intercropped chick-peas ,but lower in intercropped maize than mono-cropped one .Particularly ,it was found that the Al-P at P40 level (P application rate of 40 kg·hm-2 ) ,Fe-P at P0 (Without P application) level ,and Ca10 -P at P80 level (P application rate of 80 kg·hm-2 ) of intercropped maize were significantly lower than those of mono-cropped one .
