白花泡桐生长快、材质好、用途广,是产值高的树种之一。目前,广西多是四旁零星种植,上山成片造林的不多,为了探讨白花泡桐上山造林、速生丰产技术,我所于1978年2月营造了四十亩试验林,于1980年11月测定,全林平均树高为7.28m,平均胸径为 10.4Cm,平均地径为13.5Cm,目前长势良好,桐林茂盛。我们的做法如下:
White Paulownia grow fast, good material, wide use, is one of the tree species with high output value. At present, Guangxi is mostly surrounded by sporadic plantations, and there are not many afforestation sites in the mountains. In order to explore the afforestation and fast-growing and high-yielding techniques of Paulownia tomentosa, I built forty acres of experimental forest in February 1978 and measured it in November 1980, The average height of the whole forest is 7.28m, the average diameter at breast height is 10.4cm and the average diameter is 13.5cm. At present, the growth is good and Tonglin flourishes. Our approach is as follows:
