摘要
为有效阻控果园水土流失,提高土壤有机质,培肥地力,促进果树生长,在果园长期套种圆叶决明Chamaecrista rotundifolia、平托花生Arachis pintoi等牧草。结果表明:无论顺坡还是平台果园套种牧草,均能显著提升土壤有机质含量,增幅为9.09%~32.81%,和顺坡相比,平台果园套种牧草更有利于土壤有机质的积累。随着试验年份的推移,所有处理土壤富里酸和胡敏酸含量总体呈增加趋势,顺坡和平台果园套种牧草更有利于土壤腐殖质的积累,而且套种平托花生的效果优于圆叶决明。
In order to effectively prevent and control the soil erosion,improve the soil organic matter&soil fertility and promote the the growth of fruit trees,the herbages such as Chamaecrista rotundifolia and Arachis pintoi were interplanted in the orchard for a long time.The results showed that interplanting the herbages could significantly increased the content of soil organic matter in both the downward slope and terrace orchard,with an increase of 9.09%-32.81%.Interplanting herbages in the terrace orchard was more beneficial to the accumulation of soil organic matter than that of the downward slope.With the passage of testing years,the contents of fulvic acid and humic acid in all the treated soils showed an overall increasing trend.And interplanting herbages in the the downward slope and terrace orchard were more beneficial to the accumulation of soil humus,and the interplanting effect of Arachis pintoi was better than that of Chamaecrista rotundifolia.
