银杏北方栽培技术初探

探索高纬度地区栽培银杏树技术，考察其成活率，及生长条件。采用2年龄苗木移栽。当年秋季带土装盆放入室内，存放温度5-10℃，湿度50％-75％。次年春，移回大地。以后冬季不用移回室内，成活率94％以上。根据银杏树的生长规律，采取科学的管理方法，在北纬43°51’，东经125°18’的北温带地区银杏树生长良好，对高纬度地区栽培银杏树具有一定指导作用。

Exploration of Planting the Maidenhair Tree in the North

To explore the technique of planting the maidenhair tree in the high latitudes,the livability and the condition of growing was studied,we ehosed 2-year-old seedlings of maidenhair tree,transplanted them with soil into indoor flowerpots in autumn. The temperature of preservation was 5-10℃ and the humidity was 50-75%. Then replanted them to the field in the next spring and no longer removed them into the house. The livability was over and above 94%. According to the growing rule of the maidenhair tree,we adopted the scientific method of management,and finally the maidenhair tree grew well in the north temperate zone of 43°51 ＇N and 125°18＇E,it showed considerable significance to plant the maidenhair tree in the high latitudes.
