摘　　要：毛叶苕子耐旱、耐寒、生长速度快,是中国北方的主要绿肥作物,但毛叶苕子高产栽培技术以及种子高产繁育技术研究甚少。在内蒙古阴山北麓进行了播种期、播种量和施肥量对毛叶苕子产草量以及籽实产量的影响田间试验研究,结果表明:影响毛叶苕子产草量的主要因素是播种量,其次是播种期,施肥量影响相对最小。5月10-25日播种、播种量45.0～82.5kg/hm2、施肥量45～135kg/hm2产草量较高,不同因素对毛叶苕子籽实产量的影响依次为:播种期>施肥量>播种量,适时早播(4月25日至5月10日播种)、合理密植(播种量15～60kg/hm2)、适量施肥(磷酸二铵45～90kg/hm2)是获得籽实高产的关键。Hairy vetch（Vicia villosa Roth.） is the main green manure crops with character of drought tolerance,cold resistance, fast growth in north China,but there were little study on its hig-yield cultivation and seed breeding technology.So an experiment of the influence of sowing date,seeding rate and fertilizer rate on grass and grain yield of hairy vetch was carried out in the northern foot of Yinshan Mountain in Inner Mongolia.The results showed that the grass yield of hairy vetch was mainly influenced by the seeding rate,and the followed by seeding time and the fertilizer rate.The highest grass yield was in the treatment of sowing on May 10-25,seeding rate of 45.0～82.5kg/hm 2 and fertilizer amount of 45-135kg/hm 2.The effects of these factors on grain yield were different with on the grass yield and the influence was as follows： the sowing time fertilizer amount seeding rate.In conclusion,early sowing in good time（April 25-May 10 seeding）,rational close planting（seeding rate 15-60 kg/hm 2） and proper amount of chemical fertilizer（dap of 45-90kg/hm 2） were the key to obtain high yield of grain.
