一、品种特性 大豆芽生长前期不需强光、大水。适宜气温为25～30℃,地温为20～22℃。豆芽抗病性差,忌原土连作,生长期怕冷凉,干风易引起冻伤和脱水闪苗。 大豆芽分黄豆芽、红豆芽、黑豆芽。黄豆芽(晋南称白豆)选用小粒型夏播品种(如平顶黄、向阳5号等),产出比为1∶7。红豆芽选用东北舒兰夏播红豆,适宜四季生长,产出比1∶11。黑豆芽色泽略暗,适口性较差,产出比
First, the characteristics of varieties The growth of soybean sprouts without glare, flood. Suitable temperature is 25 ~ 30 ℃, ground temperature is 20 ~ 22 ℃.
