摘要
银中杨是黑龙江省防护林研究所1961年以熊岳的银白杨为母本,以当地中东杨为父本,经人工杂交选育而成。1984年通过品种鉴定,属于白杨派品种,为雄性无性系,具有树形美观、速生、抗病虫能力强、耐寒、耐瘠薄等优良特性。既是营造速生丰产林的优良树种,也是城乡绿化,特别是大中城市绿化的首选树种。但常规扦插育苗成活率较低,正常情况下,成活率仅30%左右。近十年来,法库地区采用黑地膜覆盖技术,同时将插穗进行药剂处理,使银中杨育苗成活率达到95%以上。本文详细介绍了法库地区银中杨黑地膜覆盖硬枝扦插育苗技术,为同类地区银中杨育苗提供参考。
Silver poplar is a male clone of the Populus alba sect, which was artificially bred by the Heilongjiang Provincial Shelterbelt Research Institute in 1961, using Xiongyue’s Populus alba as the female parent and local Middle Eastern poplar as the male parent. It was identified as a species in 1984 and belongs to the Populus alba sect. It has excellent characteristics such as beautiful tree shape, fast growth, strong resistance to diseases and pests, cold resistance, and barren tolerance. It is not only an excellent tree species for creating fast-growing and high-yield forests, but also the preferred tree species for urban and rural greening, especially in large and mediumsized cities. However, the survival rate of conventional cutting seedlings is relatively low, and under normal circumstances, the survival rate is only about 30%. In the past decade, the Faku area has adopted black plastic film covering technology and treated cuttings with pesticides, resulting in a survival rate of over 95% for the seedlings of Populus alba. This article provides a detailed introduction to the hard branch-cutting seedling cultivation technology of silver poplar covered with black plastic film in the Faku area, providing a reference for the seedling cultivation of silver poplar in similar areas.
