[目的]为宁夏大面积发展种植中科系列羊草提供技术支撑。[方法]以中国科学院植物研究所培育的中科系列羊草Y1、Y3、B、BG、BG-2品系为试验材料,对其在宁夏3个不同土壤典型区中的生态适应性进行评价。[结果]结果显示,宁夏各地区中科系列羊草均能够顺利完成生命周期;黄河灌溉区域适宜发展羊草种子田,可选择中科系列羊草Y1、Y3品系,盐碱地可选择种植中科系列羊草BG-2品系。[结论]由于羊草生长发育状况受到多因素的影响,与土壤类型、土壤水分条件紧密相关,在土壤、水分较多地区,羊草能发挥出较大的生产能力,但是人为采取的农艺措施也是不容忽视的因素。
[Objective] The research aimed to provide technical support for the large-scale development and planting of Leymus chinensis family in Ningxia. [Method] With the Chinese family Leymus chinensis Y1, Y3, B, BG and BG-2 strains cultivated by Institute of Botany, Chinese Academy of Sciences as test materials, the ecological adaptability in three typical soils of Ningxia was evaluated. [Result] The results showed that all the Leymus chinensis families in Zhongke and Ningxia were able to successfully complete the life cycle. The Leymus chinensis seedlings were suitable for the irrigation in the Yellow River, and Zhongke series Leymus chinensis Y1 and Y3 could be selected for irrigation. Leymus chinensis BG-2 strain. [Conclusion] Because the growth and development status of Leymus chinensis was influenced by many factors, it was closely related to the soil type and soil moisture condition, and Leymus chinensis played a great productive capacity in the soil and water areas. However, the agronomic measures It is also a factor that can not be ignored.
