摘要：

Over a three year period, the day-neutral strawberry cultivar Tribute was treated with two rates of nitrogen (N) (50 and 100 kg/ha), four rates of potassium (K) (0, 60, 120 and 180 kg/ha) and three rates of magnesium (Mg) (0, 25 and 50 kg/ha) fertilizer from June to September from 1993 to 1995. Optimal rates of N, K and Mg in relation to fruit yield and average fruit weight for 25 fruits were studied. Fertilizer was applied through a trickle irrigation system. The results showed that N and K treatments had no significant influence on yield and fruit size. However, a 25 kg/ha application of Mg did increase fruit yield for 1993 but not for the other two years. Mg had no effect on yield.
