黑龙江省是我国高寒地区,植物生长季很短促,蔬菜品种远不如我国南方丰富。3—6月份更是蔬菜供应的大淡季,能露地越冬的蔬菜,目前只有大葱、韭菜和菠菜三种,它们也是早春大棚生产的最早蔬菜。为增加高寒地区淡季的蔬菜品种,我们在王敬立先生指导下,进行完达蜂斗菜的引种试验。 Heilongjiang Province is China’s alpine region, the plant growth season is very short, far less than the rich variety of vegetables in southern China. March to June is the big off season of vegetable supply, vegetables that can be exposed to the winter, there are only three kinds of green onions, leeks and spinach, they are also the earliest vegetables produced in early spring greenhouses. In order to increase the off-season vegetable varieties in the alpine region, under the guidance of Mr. Wang Jingli, we introduced the introduction test of butterbur.
