白花桐(福氏桐),是速生用材树种之一。为合轴分枝,较之当地的毛泡桐,兰考桐,更有利于培养优质高杆良材。该树种对日灼、丛枝病抗性强,材质好,用途广,在工业、医药、军事方面占有重要的地位。同时,也是一种良好的农田林网化树种。白花桐在我场是首次引种。由于我场地处旱原区,地下水位低,土壤贫瘠,干热风多,给育苗造成一定的困难。1975年,我们开始进行白花桐播种育苗试验,出苗率80％,苗高1.5米,地径2厘米,每亩产苗量为45000株。1976年,在总结75年育苗经验教训的基础上,又进行了较大面积的育苗试验,经过精心管理,出苗率在85％以上,幼苗生长旺盛,长势良好。高生长1.62米,地径2.3厘米,每亩产苗量58000株。经过两年的育苗实践,我们初步积累了一点经验,介绍如下: Bai Hua Tong (Fu Tong), is one of the fast-growing timber species. For co-axial branches, compared to the local Paulownia Paulownia, more conducive to the cultivation of high quality rod material. The species of sunburn, Shuchan strong resistance, good material, wide use, in the industrial, pharmaceutical, military occupies an important position. At the same time, is also a good species of farmland network of trees. Baihuatong in my field is the first introduction. As my site is located in arid area, the groundwater level is low, the soil is poor and there are many hot and dry winds, causing certain difficulties to nursery. In 1975, we started sowing seeding plantlets with the rate of emergence of 80%, height of 1.5 meters and diameter of 2 cm, yielding 45,000 plants per mu. In 1976, on the basis of summing up the experiences of 75 years of seedling raising, a large area of ​​seedling raising experiment was carried out. After careful management, the germination rate was over 85%. Seedlings grew vigorously and grew well. High growth of 1.62 meters, 2.3 cm in diameter, yield of 58000 plants per mu. After two years of nursery practice, we have initially accumulated a little experience, introduced as follows:
