苦麻菜是我国著名叶菜类高产饲料作物,1974年以来先后从上海、安徽、河北等地引入我省。经过几年的栽培饲用,证明苦麻菜是猪、鸡、兔的优良青绿多汁饲料,很有推广价值。由于苦麻菜原产我国南方,在我省种子不能成熟,因此,每年都要从外地引种,消耗很大,影响推广。为此,我们从1974年开始,利用河北 The bitter wormwood is a famous high-yield fodder crop for leafy vegetables in China. Since 1974, it has been introduced into the province from Shanghai, Anhui and Hebei. After several years of cultivation and feeding, it has been proved that the bitter wormwood is an excellent green and juicy feed for pigs, chickens and rabbits, which is of great value for promotion. Since bitter worms are native to southern China, they cannot be matured in our province. Therefore, they must be introduced from other places every year, which consumes a lot and influences promotion. To this end, we started in 1974 and used Hebei.
