贵南柳等灌木树种在沙地生长适应性研究

Study on Growth Adaptability of Shrub Species Such as Salix Guinan in Sandy Land

摘要: 目前我国土地沙漠化严重，林业生态资源得不到有效的保护，破坏严重，所以选择合适的树种在沙地进行栽植成为防风治沙的关键。本次试验主要是在相同条件下通过植物生长调节剂对植物进行处理，观察树种在沙地生长表型适应情况，比较贵南柳等灌木树种的株高、冠幅、地径、新梢生长量、侧根长、侧根数、新生根长、新生根数来挑选出适宜沙地生长的树种，为治沙提供一定的理论依据。

Abstract: At present, China’s land desertification is serious, forestry ecological resources can not be effectively protected, serious damage, so the selection of appropriate tree species planting in sandy land has become the key to wind and sand control. This experiment is mainly under the same conditions through the plant growth regulator on plant for processing, observe trees grow in the sand pheno-type to adapt to the situation, more expensive south willow shrub tree species such as plant height, crown breadth, ground diameter, new shoots, lateral root length, lateral root number, new root length, root number to pick out the suitable for the growth of the sand tree species, provide certain theoretical basis for sand.
