不同施钾水平对红富士苹果产量和品质的影响

摘要

通过施用不同水平钾肥对果树果实品质及产量的影响研究，结果表明，增施钾肥能够有效地改善红富士苹果果实的各项品质指标。但是钾素对果树各个指标的影响只是在一定的范围内效果较为明显，当超过这个范围的时候，增施钾肥表现出对各个指标的抑制。%The effects of different potassium levels are tested by the administration of fruit quality and yield of fruit trees.The results show that the potassium can improve the quality of Red Fuji apple avail⁃ably. Howbeit the accelerate effect only happens when the dosage of potassium is in a certain bound,it baf⁃fles the accelerate effect when dosage of potassium oversteps the bound.
