摘要

对轮作及大豆、玉米、小麦长期连作白浆土中氮含量及有机态氮组分变化进行研究。结果表明，在不施肥情况下，小麦连作区土壤由全氮、碱解氮降幅最大，酸解总氮、氨基酸态氮和氨基糖态氮降幅最小。在施有机肥情况下，土壤全氮、碱解氮及酸解总氮则以小麦连作区增幅最小，玉米连作区增幅最大；氨基酸态氮和氨基糖态氮在轮作区增幅最大。其他组分氮在轮作与连作小区间变化无规律。

Abstract

The nitrogen contents and nitrogen forms were studied in albic soil with long-term crop rotation and soybean

maize

wheat continuous cropping. The results indicated that under no fertilization condition

the decreasing range of total nitrogen

alkaline-hydrolyzable nitrogen were largest

but hydrolizable nitrogen

amino acid nitrogen

amino sugar nitrogen were least in the wheat continuous cropping plot. Under applying manure condition

the increasing range of total nitrogen

alkaline-hydrolyzable nitrogen were least in the wheat continuous cropping plot

but were largest in the maize continuous cropping plot. The increasing range of amino acid nitrogen and amino sugar nitrogen were largest in crop rotation plot

and the variation of the other nitrogen forms could not been found law in the two cultivations.
