不同土壤含水量对二色补血草生长状况的影响

Influence of the Different Soil Moisture Content on the Growth of Limonium Bicolor

二色补血草是内蒙古草原广泛分布的野生花卉之一。通过对二色补血草在不同的土壤含水量条件下生长状况的观测研究,确定了适宜的温室引种栽培野生二色补血草土壤含水量范围,为野生二色补血草的引种扩繁提供了依据,通过试验证明,在其它条件均相同的情况下,野生二色补血草种子的出苗数随着土壤含水量的升高呈单峰曲线。在土壤含水量为33.1%时出现峰值;在土壤含水量小于33.4%时,二色补血草的最大叶长、最大叶宽、叶片数、冠幅等形态特征与土壤含水量呈正相关。

Limonium bicolor is one of the wild flowers that distributes widely in Inner Mongolian grassland.This experiment observed and investigated the different soil moisture content condition of the Limonium bicolor,then determined the suitable soil moisture content scope for the greenhouse for cultivation of wild Limonium bicolor.It also provided the basis for introducing and expanding of Limonium bicolor.The experiment showed that under the homogeneous condition,the seedling number of wild Limonium bicolor assum...
