紫穗槐在松嫩草原盐碱地区的引种试验

Introduction of Amorpha Fruticosa L.in the Saline-alkali Soil of Songnen Grassland

在松嫩草原盐碱化程度不同的土壤进行紫穗槐引种试验,从植株地上部分和根的生长状况以及生物量等调查项目来看,紫穗槐在pH值8.65左右的低盐碱化的土壤中可以正常生长,植株和根的生长状况良好.但在pH值10.20的盐碱化程度较高的试验地中,紫穗槐的生长极为缓慢.

Amorpha fruticosa L. is planted and grown up in the experimental plots of saline-alkali soil with different degrees in Songnen Plateau. By observing the data of the height of plant tnmk on the ground, stem diameter, the length and diameter of taproot, the total aboveground biomass of Amorphafruticosa L. and so on, it is shown that Amorphafruticosa L. can grow up naturally in the experimental plot of lower saline-alkali soil with about pH 8.65 degree, whose plant and root can be in good condition. However, in the experimental plot of higher saline-alkali soil with about pH 10.20 degree, Amorpha fruticosa L. grow very slowly.
