| 摘 要： | 采用三室根箱研究了磷高效小麦 81( 85)-5-3-3-3及磷低效NC37两个小麦品种根际磷转化及VA菌根对根际土壤磷转化的影响。结果表明 ,磷胁迫下 ,81( 85)-5-3-3-3的吸磷量略高于NC37,两种小麦品种根际土壤均形成了明显的Olsen-P ,Ca2-P ,Ca8-P ,Al P等形态磷的耗竭区。两种小麦品种在不施磷肥和施用磷肥下接种VA菌根 ,小麦的生物量、植株磷浓度、小麦根际Olsen-P,Ca2-P ,Ca8-P,Al-P ,Fe-P的消耗量均显著增加 ;根际、非根际土壤各形态磷素的浓度梯度明显降低。

| Abstract: | The transformation of P in the rhizosphere of wheat and theeffect of VAM to P transformation in rhizosphere of wheat was studied . The results showed that the amount of uptake phosphorus by 81(85)-5-3-3- 3 was higher than NC37. The contents of Olsen-P, Ca2-P, Ca8-P and Al-P was lower in the 0-2mm，2-4mm rhizosphere soil than bulk soil. VA mycorrhizae increased the uptake of the fractions of Olsen-P, Ca2-P, Ca8-P, Al-P, Fe-P and improving growth of 81(85)-5-3-3-3 and NC37 especially in soils with low phosphorus content and the concentration in rhizosphere and bulk soil decreased significantly. |
