对紫花苜蓿品种维多利亚(victorian)在南方丘陵山地红壤土不同播量、不同播期进行试验,考察不同播种量与出苗率和密度、刈割平均株高、分枝数、越夏存活率、青草产量、茎叶比和鲜干比的关系;播种到出苗、齐苗的时间及适宜播期;播种至出苗、齐苗的积温数及其关系;不同播期处理的出苗与越冬存活率等。结果表明,每亩播种量以1.0～1.5kg为宜。播种时间秋播以10月中下旬为宜,春播以3月中旬为宜。
The effects of different sowing rates, seedling emergence rate and density, mean cutting height, branch number, survival rate of over summer, grass weight of grass were studied on different sowing and sowing times of red alfalfa cultivars victorian in hilly area of southern China. Yield, stem-leaf ratio and fresh-dry ratio; sowing to emergence, Qi Miao of the time and suitable sowing date; sowing to emergence, Qi Miao number of accumulated temperature and its relationship; different sowing date of emergence and overwintering survival rate. The results showed that the acreage per acre 1.0 ~ 1.5kg is appropriate. Autumn sowing time in late October is appropriate, spring sowing mid-March is appropriate.
