摘　　要：目的:探讨研究黑龙江省三江平原越冬之星苜蓿菟丝子净度筛选及综合防除技术,可得出对越冬之星苜蓿菟丝子净度筛选方法和防除技术.方法:通过越冬之星苜蓿种籽、菟丝子净度筛选比较试验进行观察记载.结果:经风选两次的越冬之星苜蓿种籽,再经64孔/m2的筛子(即20目标准筛)筛选,越冬之星苜蓿种子的净度为100%.结论:依据不同风选与筛选所作的结果,因之我们认为64孔/m2的筛子,是清选越冬之星苜蓿种籽、菟丝子种籽较好的筛孔规格.The winter star alfalfa dodder purity screening and comprehensive control techniques in San- jiang plain of Heilongjiang province were studied. The conclusion that the purity screening methods and control technique of winter star alfalfa dodder was obtained. The winter star alfalfa seed and the purity of screening test of dodder were observed records. By fanning two times of winter star alfalfa seeds and 64 holes/m2 sieve （20 mesh/standard sieve） screening, the seed purity of winter star alfalfa was 100%. According to different wind and screening, 64 holes / m2 sieve is a good seed mesh specifications in cleaning the seed of winter star alfalfa and dodder.
