摘　　要：以镇稻8号为材料,研究了不同用量冷杉针叶三萜酸对水稻产量和品质的影响。结果表明,与喷清水对照相比较,施用冷杉针叶三萜酸后能够提高水稻千粒重和产量,并能提高稻米的糙米率、整精米率、直链淀粉含量和蛋白质含量,改善稻米碾磨品质和营养品质。10%冷杉针叶三萜酸水乳液最适施药方法为:播种前拌种剂量80 mL/t、分蘖期和抽穗期喷施剂量80 mL/hm^2,能使水稻增产16.60%。The effects of different dosages of triterpene acids from fir needles on yield and quality of rice were studied, Zhengdao 8 as material. The results showed that the thousand seed weight, brown rice rate, head rice rate, amylose content and protein content of rice were increased, and the milling quality and nutrition quality of rice were also improved after spraying triterpene acids from fir needles, compared with the control. The best application way of 10% triterpene acids EW for rice were as following： seed dressing with 80 mL/t before sowing, foliage spraying with 80 mL/hm2 in the tillering stage and heading stage. Under the condition, the yield of rice could increased by 16.60%.
