| 摘 要： | 不同培肥措施对土壤全氮、全磷、碱解氮、速效磷的积累为:有机肥>秸秆还田>草木樨还田>化肥>对照;速效钾的累积增长为秸秆还田居首位,有机肥次之,对照区呈下降趋势。有机物料的培肥效果优于化肥。

| Abstract: | By different fertilizing,the accumulation content of total N,P,alkaline hydrolyzable Nand available P in black soil were as follows:farm manure>crop straw>sweet clover>ferti-lizer>control.The accumulation content of available K was the highest from crop strawturned under soil,and the next is from farm manure.The content of available K decreased incontrol plot.The fertilizing effect with organic material is better than with fertilizer. |
