摘要:
The results of three years of experimentation on the effect of the addition of dolomitic lime to pine bark‐sand media shows thatPhotinia‘Fraseri’ responds positively to lime additions. This response was not due to pH changes, since for two of the three years only a small change was observed in pH and lime requirement values. It is more likely that the increased growth is due to an improved magnesium environment. Not only was the magnesium content of the foliage increased with lime addition, but the K:Mg ratio was decreased to a level where potassium‐magnesium antagonism was not important.
