有的花木对土壤酸碱度颇为敏感,稍有不适,轻者不能正常生长,重者死亡。原生长在各地的花木,适于当地的土壤酸碱度。南方花木一般喜酸居多,只有在酸性的土壤上才能正常生长。如果欲将南方花木移到北方,除满足一定的温、湿度和光照条件外,调节土壤酸碱度实为重要。因为北方土壤和灌溉水质多偏碱性,南方花木在带有碱性土壤中容易发生一种生理性黄病,使叶色变黄,生长衰弱,最后死亡。因此南花北移,必须首先了解原生长地的土壤酸碱度和该花木对土壤酸碱度的要求,然后才能人为地调节新生长地的最适酸碱度。如我国华南地区的红、黄壤土多属酸 Some flowers and trees on the soil pH is quite sensitive to a little discomfort, light can not be normal growth, severe cases of death. The original growth of flowers and trees in various places, suitable for the local soil pH. Southern landscaping generally like acid, only in acidic soil to grow normally. If you want to move the southern flowers north, in addition to meet certain temperature, humidity and light conditions, the adjustment of soil pH is really important. Because the northern soil and irrigation water more alkaline, southern landscaping with alkaline soil is prone to a physiological yellow disease, the leaf color turns yellow, weak growth, and finally died. Therefore, the southward flow northward, we must first understand the original growth of soil pH and soil water and alkali pH requirements, and then to artificially adjust the optimal growth of the new pH. Such as China’s southern China red and yellow loam mostly acid
