Introduction and Selection of Forage Varieties in Yinchuan Section of Yellow River Beach in Ningxia
摘要
Abstract
In order to screen out ecological restoration varieties with strong ecological adaptability in the Yinchuan section of the Yellow River beach in Ningxia,the adaptability,plant height growth and fresh grass yield of different forage varieties in this area were studied and analyzed by field experiments.The results showed that all varieties of forage grasses could germ-emerge normally during the emergence period.Moreover,the green-up rate of the forage grasses of Poaceae family in the second year ranges from 11.4%to 97.6%,and the green-up rate of Agropyron elongatum was the highest,reaching 97.6%.The green-up rates of Medicago sativa L.ranged from 51.2%to 70.3%,with Ruide having the highest rate at 70.3%.The growth of the tested forage grasses was good.Through two years of observation,it was known that the forage grasses of the Poaceae family with better growth in plant height included Agropyron elongatum,Puccinellia distans and Leymus chinensis(Trin.)Tzvelev,which were significantly higher than that of Elymus dahuricus Turcz.(P＜0.05).There was no significant difference compared with Festuca arundinacea Schreb.and Bromus inermis Leyss..Among Medicago sativa L.,those with relatively good height and growth are Ruide and Zhongmu No.3.Among the forage grasses of Poaceae family,Agropyron elongatum had the highest yield,reaching 1 461.47 kg·667-1·m-2,which was significantly higher than that of other varieties(P＜0.05).Among Medicago sativa L.,Zhongmu No.4 had the highest yield,reaching 1 409.19 kg·667-1·m-2.Among the introduced forage grasses,Agropyron elongatum,Puccinellia distans,Leymus chinensis(Trin.)Tzvelev,Ruide,Zhongmu No.3 and Zhongmu No.4 all have good growth and grass yield,which can promote local ecological restoration and are suitable for planting in the Yinchuan section of the Yellow River beach in Ningxia.关键词
