我所于1983年从日本引进草莓良种宝交早生脱毒原种种苗20株,仅用三年多的时间,繁殖出的种苗已推广至全省各县及其它21个省、市、自治区,其中仅江苏省句容县就达2000万株以上。三年中,我所草莓的繁殖系数持续达到300倍以上,最高的单株繁殖系数达到910倍。在育苗技术上,除了建立专用采苗田,采取早栽、稀植、足肥、匍匐茎整理和加强高温期水管理、病虫防治等方法外,还采取壮苗采果,小苗育苗的分级处理方法,扩大种苗来源,加快繁殖种苗的速度。
In 1983, I imported 20 kinds of seedlings of detoxification seeds of strawberry elixirs from Japan. In just over three years, the seedlings that have been bred are popularized to all counties and 21 other provinces and cities in the province, Autonomous Region, of which only Jurong County in Jiangsu Province reached more than 20 million. In three years, the reproduction coefficient of strawberry in our country continued to reach more than 300 times, and the highest coefficient of single plant propagation reached 910 times. In nursery techniques, in addition to the establishment of special seedling field, take early planting, thinning, foot fat, stolons finishing and strengthening of high temperature water management, pest control and other methods, but also to strong seedling picking, seedling grading treatment methods , Expand seedling sources, speed up the breeding seedlings.
