黑龙江省是我国纤维大麻的主产区之一,生产中应用的大麻品种均为雌雄异株,由于雌株和雄株成熟期相差30天,不能同时收获,严重影响了大麻纤维产量和品质,采用雌雄同株品种可以克服这些缺点.通过国际合作与交流,从国外引进了一批雌雄同株大麻品种,通过对这些品种进行鉴定评价,明确其生长特性和农艺性状,为我省大麻育种和生产提供依据.%Heilongjiang province is one of the main fiber hemp production areas in our country. The hemp varieties applied in production are all dioecious, the maturation time is 30 days away between male plants and female plants, which can affect the fiber quality severely for the two different gender plants can not be harvested at the same time. There are not such shortages for the monoecious varieties. A number of monoecious hemp varieties were introduced through international cooperation and exchange from abroad, and their growth characteristics and agronomic traits were identified and assessed after being planted in Heilongjiang. Some research results were obtained so as to provide support for hemp breeding and production.
