泡桐是一种优良速生用材树种。材质轻软,纹理较直,干后不翘不裂,耐湿,防火,不易传热,是制作航空模型、胶合板、各种器具和乐器的优良用材。泡桐木材历来为我国重要出口物资。近年来,我省渭北旱原地区泡桐发展很快.为了适应生产需要,1974年6月下旬至7月上旬我们调查总结了合阳县泡桐旱地埋根育苗的经验。 Paulownia is a good fast-growing timber species. The material is light and soft, the texture is straight, dry and cracked, moisture-resistant, fire-proof and not easy to transfer heat. It is an excellent material for making aviation model, plywood, various instruments and instruments. Paulownia wood has always been an important export material for our country. In recent years, the development of Paulownia in the Weibei rainfed region in our province has been developing rapidly.In order to meet the production needs, we conducted a survey and summarized the experience of planting the rooted shoots of Paulownia dryland in Heyang County from late June to early July 1974.
