泡桐为速生,优质,分布较广的树种.根据一般概念,泡桐是不太耐盐的.但究竟不太耐盐到何等程度(即耐盐幅度),在盐渍土栽植泡桐又有何反应,等等,报导甚少.为了探讨泡桐生长和盐渍度的关系,找出耐盐幅度和耐盐的极限,为我省广大盐渍土地区发展泡桐,提供科学的理论依据,我们从1980年开始,进行了以泡桐种子、种根及实生苗为试验材料的耐盐性试验,已取得了一些结果.现初报如下:试验方法一、泡桐种子发芽耐盐性测定测定是在90毫米口径的培养皿中进
Paulownia is a fast-growing, high-quality, widely distributed tree species.According to the general concept, Paulownia is not too salt tolerant.However, not to the extent of salt tolerance (ie salt tolerance), planting paulownia in saline soil, what reaction Etc. In order to explore the relationship between the growth of paulownia and the degree of salinity, find out the limits of salt tolerance and salt tolerance, and provide scientific theoretical basis for the development of paulownia in the vast saline soil area of our province from 1980 Year started with the Paulownia seeds, seedling roots and seedlings as the test material salt resistance test, and some results have been achieved. The first report is as follows: Test Method I. Paulownia seed germination salt tolerance determination is measured at 90 mm Caliber Petri dish into
