小黄花(Hemerocallis minor Mill)为多年生草本植物,不但是营养价值较高的菜肴,还由于它抗干旱、耐瘠薄、分蘖力强,所以又是优良的水土保持植物。河北省塞罕坝机械林场在小黄花覆盖率达35%的沙丘阳坡,基本不存在水土流失。1991年春、夏、秋3季,我们在多年造林均不能成活和保存的沙丘阳坡进行小黄花播种绿化试验,获得成功。 Hemerocallis minor Mill, a perennial herb, is not only a dish with high nutritional value, but also an excellent soil and water conservation plant due to its resistance to drought, barrenness and tillering. Saihanba mechanical forest farm in Hebei Province in the small yellow flower coverage of 35% of the dune sunny, basically no soil erosion. In the spring, summer and autumn of 1991, we succeeded in sowing small yellow flowers for greening on the sunny hillsides of sand dunes that many years of afforestation failed to survive and preserve.
