摘要
研究了新品种欧美杨107,108引种到新乡地区后,其物候期、定植成活率及苗木生长情况。结果表明:欧美杨107比对照中林46萌芽期早,落叶期晚,年生长天数多15~45d;欧美杨107,108定植成活率都在92%以上,最高达到99.5%;二者都比对照生长速度快;同等管理条件下,在不同土壤质地中,砂壤土地的欧美杨107生长优于粘土和两合土;在不同土壤类型中,潮土地的欧美杨107生长优于棕壤土和褐土。
The Phenological Phases,survival rate and growth of new Populus×euramericana cv. Neva and Populus×euramericana cv. Guariento after they were introdcued to Xinxiang were studied in this paper.The result showed that the new Populus×euramericana cv. Neva ,compared with Zhonglin 46,has an earlier germination stage and later defoliation stage,thus a longer growth days of 15-45 d.The survival rate of new Populus×euramericana cv. Neva and Populus×euramericana cv. Guariento is above 92% and can reach as high as...
