摘要
2004年至2007年在台安县西北部沙化区的洪家农牧场分别选取了沙地、荒地、林地、农田地等7个不同地点作为试验与对照区进行种植苜蓿草改良沙化土壤的实验。通过实验及对土壤速效氮、速效磷、速效钾、有机质、PH值、含水量的分析,得出苜蓿草可以在台安西北部沙化区良好生长,同时具有提高沙质土壤综合肥力及生态功能的作用,种植苜蓿草还可以为牧业生产提供优良饲草,解决了养殖业原料及草场资源缺乏问题,有利于畜牧业的发展;是沙化地区走种地养地道路的一种生态恢复方式。
From 2004 to 2007,seven different sites of sand land,deserted land,forest land and farmland in Hang Jia farm of North- west deserted area of Tai An county were selected as experimental area and comparative area to plant alfalfa and ameliorate sandy soil. Through developed experiment and analyzed quick-acting nitrogen,quick-acting phosphorus,quick-acting potassium,organic matter, Ph value and water content,the result showed that alfalfa could be grown well in Northwest deserted area,and it had roles to enhan...
