摘要
通过对银中杨生长特性研究表明 ,银中杨在生长方面超过当地推广树种小黑杨 ,其中材积生长超过小黑杨 73.4 %～ 2 6 9.2 % ;在本地区生长超过目前东北、内蒙及华北地区的优良杨树品种。探讨了银中杨生长规律及适宜栽植密度 ,并对银中杨生长划分 5个时期 ,为合理经营银中杨提供科学依据。
Studies on growing characteristics of Populus albe × P.berolinensis Dipple Showed,that growth of the poplar exceeded the spreaded Local species Populus simonii × P.nigra by 73.4%～269.2% in Volume growth.Growth in local region exceeded some superior species in the Northeast and North of China.The growth regularity and proper planting density of Populus alba × P.berolinensis was also researched.5 growth stages were devided,that provided scientific basis for proper silviculture of the poplar.
