摘要
试验研究了不同滴灌带布设方式对紫花苜蓿的植株高度、茎粗、分枝数、根系生长、根系密度和产量等指标的影响,以期为滴灌在人工牧草种植中应用提供理论依据。结果表明:滴管带埋设深度和间距不同对苜蓿各个生育期生长特性指标影响不同。在苗期,埋设深度为10 cm间距为90 cm的处理,有利于苜蓿生长。从分枝期起,埋设深度为30 cm、间距为90 cm的处理优于其他处理。
The experiment is conducted to study the influence of different layout type of drip irrigation tape on the growth characteristics indexes of Alfalfa, including plant height, root collar diameter, branch number per plant, main root length, weight density and yield, in order to provide theoretical basis for the application of drip irrigation in planting of forage. The results show that the burial depth and layout interval of drip irrigation tape have different influence on growth characteristics indexes of Alfalfa in different growth stage. In seedling stage, the treatment, in which the burial depth is 10 cm and the layout interval is 90cm, is the most suit able for the growth of alfalfa. While from the branching stage, the treatment in which the burial depth is 30 cm and the layout inter val is 90cm, is better than other ones.
