| 摘 要： | 三年田间定位试验结果证明,对豫西地区富士苹果树增施氯化钾,可使树体营养状况有明显提高,果实品质得以明显改善,且产量增幅可达6.1%～19.0%。施钾时期以当年果实膨大期(6～8月)追施为好。N、P2O5、K2O以1∶1∶1或1∶1∶1.5的施用比例且每666.7m2施39.8～59.8kg氯化钾的综合效果和效益最好。

Effect of Application of Potassium Fertilizer on Production and Fruit Quality of Apple Trees |
| |
| Abstract: | Results of over3year applying fertilizers on Fuji apple trees in the western part of Henan province showed that ap-plication of potassium chloride could obviously increase the nutrition level of the trees and improve the fruit quality;the pro-duction could be increased by6.1%～19.0%.The suitable period for applying potassium fertilizer was in the period of fruit en-largement.It also showed that application of it as supplemental fertilization was better than used as base fertilizer.The opti-mum ratio of N,P 2 O 5 ,K 2 O was1∶1∶1or1∶1∶1.5and the appropriate amount of application of potassium chloride was39.8～59.8kg /666.7m 2 . |
