| 摘 要： | 二年生白花草木栖是吉林省的主要绿肥作物,在某些地区已推广应用,但在某些地区在推广上尚有困难,对其效果及利用方法尚有不同看法.因此,结合我省草木栖的生产实际,对草木栖根瘤固氮进行调查研究,可为草木栖的生产应用提供理论依据.

| Abstract: | Biennial sweet clover (Melilotus.albus Dear) is the main green manure crop in Jilin Province.The nodulation and nitrogen fixation activity of nodules of biennial sweet clover in different soils were investgeted during 1979-1980.Nodulation arrd nitrogen fixation activity (A.R.A) were found in all plants and nodules of the sweet clover in field,but their differences were greater between different soils.The fresh weight of nodule was highest in meadow black soil (about 3g per soil core),and it was getting decreased from warped soil,podzolic soil,black soil,to salt-affected soil in which it is lowest (less than 0.1g per soil mre). |
