加拿大紫叶稠李种子繁殖技术的试验研究

加拿大紫叶稠李种子繁殖试验自2002年秋季开始,从加拿大埃德蒙顿引进紫叶稠李种子500g。并对种子进行发芽试验,采取不同方法,从中筛选种子发芽早,出苗率高,分枝多的最佳种子处理方案,使紫叶稠李这一彩叶树种的种子繁殖技术得到应用与发展,批量生产绿化苗木,从而添补园林绿化彩叶树种之不足,为城市绿化、美化、彩化提供良好素材。

A trial research for breed technique of Dense Lee's seed of Canadian purple leaf

The breaed experiment of Dense Lee's seed of Canadian purple leaf began in the autumn of 2002,Dense Lee's seed 500 gs of purple leaf were introuduced from the Canadian Aidemengdun.Carrying on germination's experiment on the seed and adopting the different methods,the best seed processing project has been choosed from sieving seed sproutlace early,a high seedling rate and dividing the best seed,make the seed breed technique of colourful leaf's tree of purple leaf,dense LI3 ZHE4 YI,applied and developed;Have a batch production and an afforestation;therefore,replenish the shortage of colourful leaf's tree seed,which has provided the good material for the city greening,beautifying and colouring.
