泡桐是我国最速生的用材树种之一。它的许多优良特性已为越来越多的人所了解,并引起重视。随着社会主义建设的发展,栽植泡桐的规模越来越大,但由于对泡桐的特性以及适生条件缺乏深入的了解,故在引种、栽培技术上还存在一些问题。如南方一些地区盲目地从北方调运大量不适宜在南方种植的泡桐种条,误认为结实多的就是好品种,其实在北方结实多的大多是毛泡桐和光泡桐,这两种在北方一般生长不良。北方泡桐丛枝病较严重,大量引种,可能引进带病种根,对少有此病的南方不利。由于对泡桐的特性不够了解,未能做到科学植桐,这样就会给生产上带来不必要的损失。为此,我们在总结全国 Paulownia is one of the fastest growing timber species in our country. Many of its excellent features have become known and valued by more and more people. With the development of socialist construction, planting Paulownia size is more and more large, but due to the characteristics of Paulownia and the lack of in-depth understanding of the conditions for the fit, so the introduction, cultivation techniques there are still some problems. For example, some areas in the south blindly transferred a large number of Paulownia species planted unsuitablely for planting in the south from the north. They mistakenly believed that they are good varieties with a high degree of solidity. In fact, most of the strong in the north are Paulownia and Paulownia, both of which are generally poorly grown in the north . Paulownia witches broom disease more serious, a large number of introduction, the introduction of the disease may be the root of the disease on the south of the disease is not conducive. Due to lack of understanding of the properties of paulownia, failed to make scientific planting paulownia, so it will produce unnecessary losses. To this end, we are summarizing the country
