摘要
试验在贵阳、独山、威宁、兴仁4个不同区域对威宁地八角与野生地八角的物候期、生长情况、产量性状进行为期2年的综合评比观测。结果:威宁地八角在4个试验点的年均鲜草产量和种子产量分别为3 197、23.20 kg/667 m~2,分别比野生地八角增产12.49%、24.46%,差异显著(P<0.05),且具有较好的生产性能和适应性,可在贵州省内类似地区作为改良草地的适宜牧草新品种推广利用。
The phenological period,growth condition and yield characteristics of Weining A.bhotanensis and uncultivated A.bhotanensis were observed for 2 years in four different regions: Guiyang,Dushan,Weining,Xingren. Results: that the average annual fresh grass and seed yield of Weining A.bhotanensis were3 197 kg/667 m~2 and 23.20 kg/667 m~2,12.49% and 24.46% higher than those from uncultivated A.bhotanensis,with significant difference. It has good production performance and adaptability and can be used as a suitable new forage variety for improving grassland in similar areas of Guizhou province.
