摘要
从苜蓿Medicago sativa种子丰产产量构成因素和影响因子(气候条件、地形、密度、灌溉、肥料、授粉、生长调节剂、杂草、收获时间等)方面论述了我国苜蓿种子丰产研究现状,并对其研究中存在的问题进行了分析。
The current research progress on alfalfa seed production in terms of yield components and the factors, such as climate, topography, planting density, irrigation, fertilization, pollination, plant growth, weeds and harvest time in China was discussed, and the problems existing in research work were analyzed as well.
