摘　　要：以草莓品种‘红艳’为试材,研究不同用量的冷杉针叶三萜酸制剂对草莓产量和品质的影响。结果表明,冷杉针叶三萜酸制剂的最适用量80~100m L/hm^2,在草莓植株2~3叶期、定植后和初花期进行3次喷雾施药,与清水对照相比较,草莓产量增加了20.54%~23.07%,果实可溶性固形物含量提高了12.34%~14.74%,可溶性糖含量提高了14.43%~17.11%,维生素C含量提高了2.53%~2.73%,可滴定酸含量降低了10.26%~11.54%。‘ Hongyan＇ strawbenT as test material, the effects of different amounts of triterpene acids from Fir nee- dles on yield and quality of strawberry were studied by the method of spraying leaf surface. The results showed that the optimmn spraying condition of 10% triterpene acids EW were 80 - 100 mL/hm2 in the phase of 2 - 3 leaves, after fixed planting and in the phase of beginning of blossoming. Under these conditions, the yield of strawberry fruits was increased by 20.54% -23.07% , the contents of soluble solids, soluble sugar and vitamin C of straw- berry fruits were increased by 12. 34% - 14.74% , 14.43% - 17. 11% and 2.53% -2.73% respectively, while the content of titration acid of strawberry fruits was decreased by 10. 26% - 11.54% in comparison with water （control）.
