摘　　要：对早生高墨、巨峰、康太3个品种的六年生结果树施用钾肥,设50,100,200,400g/株4个施肥处理。结果表明,施用钾肥明显提高了果实可溶性固形物含量,增加了产量,最大增产幅度达20.5％。增施钾肥促进了枝条成熟,提高了枝条粗度。叶柄中P、K含量随施肥量的增加而升高。本试验最适施肥量为400g/株。The results indicated that soluble solid matter, yield were increased by soil-potassium fertilization. the yield of grape with potassium fertilizer treatment was increased 20. 5% higher than ck. Shoot ripenning and shoot diametre were also increased. Leaf P. K content was increased with the successively appling of soil-potassium. According to the results, appling of 400g per plant soil-potassium fer tilizer was suitable for grape production.
