我省于1977年从河北省引进苦荬菜,分别于肇源,林甸,绥化和齐齐哈尔等地试种,结果产量高,品质好、含粗纤维少。茎叶柔嫩多汁,畜禽喜食,是发展畜牧业的高产优质青饲料。但因我省无霜期较短,苦荬莱生育期较长,因此得不到成熟的种子,影响了推广应用。黑龙江省畜牧研究所从1977年开始进行早熟苦荬菜的选育工作。经过连续5年的人工选择(多次混合选择法)和自然条件的风土驯化,现已育出早熟苦荬菜,生育期比原引苦荬菜缩短20多天,成熟植株达98%以上。1982年繁殖良种200多斤,1983年在省内推广种植,使苦荬菜在黑龙 The province introduced the bitter gourd vegetable from Hebei Province in 1977, which was planted in Zhaoyuan, Lindian, Suihua and Qiqihar, respectively. The result was high yield, good quality and less crude fiber. Stems and leaves juicy, livestock like eating, is the development of animal husbandry, high yield and quality green feed. However, due to the short frost-free period in our province and the longer growth period of Bitter Laguna, no mature seed was obtained, which has affected the popularization and application. Heilongjiang Provincial Institute of Animal Husbandry since 1977, early breeding of bitter subtropical vegetables. After five consecutive years of artificial selection (multiple mixed selection method) and natural conditions of acclimatization, now weeds have developed balsam vegetables, the growth period shorter than the original cited bitter gourd shorter than 20 days, mature plants up to 98%. In 1982 breeding more than 200 kilos of seeds, in 1983 to promote planting in the province, so bitter gourd dishes in Black Dragon
