| 摘 要： | 2003-2005年在黑龙港地区安排了紫花苜蓿Medicago sativa播期试验.结果表明:紫花苜蓿适宜播期为秋播,秋播的播期阈值下限为10月上旬,10月上旬以后再播种则不能安全越冬.不同的播期对产草量产生明显影响,对品质性状鲜干比、茎叶比影响不明显.播期不同主要影响当年植株的生长发育,对第2年生长发育的影响明显减小.

| Abstract: | The sowing period experiment of alfalfa was carried out in Heilonggang area from 2003 to 2005.The result indicated that the sowing period was better in autumn than in spring for alfalfa and the most suitable sowing period was in autumn(the first ten days of October).Otherwise,it could not overwinter.The different sowing periods obviously shown the effect on the hay yield and the production performance such as the dry-fresh ratio and the leaf-stem ratio.The different sowing periods mainly affected the growth and development of alfalfa in the first year and the influence in the second year was not significantly less. |
