泡桐(Pavjownia fortunei)为落叶乔木。泡桐的主要特点是生长非常迅速,材质轻软,纹理较直,干后不开裂,不易收缩挠曲,具有耐湿防火和不易传热、虫蛀等特性,是制作航空模型、胶合板、各种家具、乐器及建筑的优良用材,也是庭园绿化的良好树种。我省气候温暖,雨量充沛,具有发展泡桐的良好自然条件。为了挖掘这个速生用材种的生产潜力,我校自一九六五年起,在红壤丘陵旱地进行了育苗试验,通过十年来的实践,初步摸索了红壤丘陵旱地培育泡桐壮苗的一些技术措施,现每年育苗数万株,基本上推广于生
Paulownia (Pavjownia fortunei) is a deciduous tree. Paulownia is characterized by the rapid growth of the material soft and light, straight texture, dry does not crack, not easy to shrink flexing, with moisture and fire and easy to heat, moth-eaten and other characteristics, is the production of aviation models, plywood, all kinds of furniture , Musical instruments and building excellent timber, but also a good tree species of garden landscaping. Warm weather in our province, abundant rainfall, with the development of Paulownia good natural conditions. In order to tap the production potential of this fast-growing wood species, our school conducted a nursery experiment in 1953 on dry land of red soil hilly region. Through the practice of ten years, we initially explored some technical measures to cultivate strong seedlings of Paulownia in hilly red soil region. Seedlings are tens of thousands of strains each year, basically promoted in the students
