中文摘要	【目的】研究新疆南疆3县新垦灌耕灰棕漠土不同团聚体无机磷组分分布规律。【方法】采用干筛法来进行土壤团聚体分级,蒋柏藩和顾益初等~([1,2])提出的无机磷分级改进法测定不同团聚体中无机磷的组分。【结果】南疆3县新开垦灌耕棕漠土中的无机磷组分随着团聚体大小增大而减少,但无机磷的变化范围因土地利用方式的不同而异。不同团聚体的无机磷组分以Ca_(10)-P为主,占无机磷总量的22%~55%。无机磷组分中含量最低的是Fe-P和Al-P,占无机磷总量的2%~6%。无机磷组分中O-P占总量的9%~30%。有效磷Ca_2-P约占无机磷总量的5%。Ca_8-P含量为无机磷总量的20%~30%。不同团聚体之间无机磷含量的差异都达到极显著的水平。【结论】在南疆3县新垦灌耕棕漠土不同团聚体中无机磷组分中以Ca_(10)-P为主,占无机磷总量的一半左右,且无机磷组分在不同团聚体中的差异都达到显著或极显著的水平。
英文摘要	【Objective】 In this project,the new cultivated irrigation farming gray-brown desert soil in three counties in Southern Xinjiang were chosen to study the component distribution of different particles of inorganic phosphorus.【Method】The dry sieve method was applied to classify soil aggregates,Jiang Bo-fan and Gu Yi-chus classification of inorganic phosphorus improving method for the determination of the components of the inorganic phosphorus in the different aggregates were used to do the research.【Result】The soil inorganic phosphorus in new cultivated irrigation farming gray-brown desert in the three counties of Southern Xinjiang decreased with increasing of the particle size.However,the changing range of inorganic phosphorus would vary due to the different land use patterns.The components of different aggregates of inorganic phosphorus were mainly to Ca_(10)-P,accounting for from 22% to 55% of the total inorganic phosphorus.Fe-P and Al-P had the lowest rate in inorganic phosphorus,which accounted for from 2% to 6% of the total.The O-P accounted for from 9% to 30% and the available phosphorus Ca_2-P covered 5%.Ca_8-P was 20% to 30%.The contents of different aggregates of inorganic phosphorus vary greatly.【Conclusion】Ca_(10)-P was a dominant composition among the total inorganic phosphorus in new cultivated irrigation farming gray-brown desert in the three counties of Southern Xinjiang,accounting for about half percentage.The difference of inorganic phosphorus content between different aggregates reached extremely significant level.
