草木樨适应性广,抗旱、耐寒、耐瘠薄、耐盐碱性较强,鲜草产量和养分含量均比较高,在我盟有较长的种植历史。近几年,由于各地二年生草木樨返青成活率变幅较大,不少地方经过深入的调查及试验研究,认为造成草木樨返青成活率低的原因,主要是早春低温冻害、病害、品种退化及人为的牲畜啃食、糟踏等。为此,根据我盟的实际情况, The broad adaptability of the vegetation, drought, cold, barren, strong resistance to salt and alkaline, fresh grass yield and nutrient content are relatively high, in our union has a longer planting history. In recent years, due to large changes in the survival rate of perennial herbaceous perennials returning to green areas, in many places, through in-depth investigation and experimental studies, the reasons for the low survival rate of perennial plants returning to greening are mainly low-temperature frost damage in early spring, disease, Artificial livestock eating, bad riding and so on. To this end, according to the actual situation of our league,
