楸树是优良的用材林和四旁绿化树种,具有广阔的发展前途,但因其结实少种子缺,影响了发展。我们根据楸树根部萌蘖力强的特点,从1979年开始连续6年进行了大面积埋根育苗,成活率都在95%以上,当年平均苗高2.15米,最高3.05米,根径2.2厘米,最粗2.9厘米。实践证明用埋根法培育楸树苗具有繁殖快,方法简单,易于推广和能保持良种的优良遗传特
Catalpa bungei is an excellent timber forest and green tree species on the four sides, has a broad development prospects, but because of its lack of strong seedless, affecting the development. Based on the strong sprouting ability of Catalpa bungei, we planted a large area of rooted nursery for six consecutive years since 1979, with the survival rates above 95%. The average seedling height was 2.15 m, the highest was 3.05 m and the root diameter was 2.2 cm , The most rough 2.9 cm. It has been proved by practice that planting Catalpa bungei has the advantages of rapid propagation, simple method, easy popularization and excellent genetic inheritance
