泡桐生长快,材质好,适应性强,深受群众喜爱。随着人民生活水平和外贸出口标准的提高,以及泡桐进大田实行农桐间作,对泡桐干高的要求也越来越高,从而提出了培育五、六米以上高于壮苗问题、但是,泡桐属于热带、亚热带树种,对温度、水分等生态条件要求较高。北方地区气候满足不了泡桐的最适条件。一般当年苗高多在3米左右。即使用高水肥圃地育苗,加强管理,苗高达到5米以上也相当困难。采用二年平茬育苗方法,又易诱发丛枝病,且经济效益低。因此,我们根据泡桐特性,针对北方气候特点,应用地面覆盖栽培的理论,进行了
Paulownia grow fast, good material, adaptability, loved by the masses. With the improvement of people’s living standards and export standards, and the implementation of Paulownia into the field Intercropping of Paulownia, Paulownia dry high requirements are higher and higher, thus raising the nurturing five or six meters above the problem of strong seedlings, however, Paulownia is a tropical, subtropical species, the temperature, water and other ecological conditions require higher. North climate can not meet the optimal conditions Paulownia. The general year when more than 3 meters in height. Even using high-water fertility nursery nursery, to strengthen management, seedling height of 5 meters or more is quite difficult. Using two years of stubble nursery method, but also easy to induce brooms, and low economic benefits. Therefore, according to the characteristics of Paulownia, climate characteristics of the North, the application of ground cover cultivation theory, carried out
