研究了增果灵对温州蜜柑产量品质的影响与部分生理效应。结果表明：（１）增果灵能促进果实发育，减少脱落，显著提高着果率，产量增产１３．６％以上；（２）增果灵对改善果实品质有明显效果，单果重提高１３．６～１４．７ｇ，果皮减薄，果面光滑，提高了果实可溶性固形物和Ｖｃ的含量；（３）增果灵能增强叶片功能，叶片增厚增重，叶绿素含量提高１５．９％～４１．２％；（４）增果灵能抑制疮痂病对果实的危害，病果率降低１０．３％～１１．０％。
The effects of Zengyuling on the yield and quality of Satsuma mays and some physiological effects were studied. The results showed that: (1) Fructus Moriiana could promote the fruit development, reduce the shedding and significantly increase the fruit yield, and the yield increased by 13.6%; (2) Fructus Moriiana improved the fruit quality obviously and the fruit weight increased by 13. 6 ~ 14.7g, peel thinning, smooth fruit surface, increased fruit soluble solids and Vc content; (3) increased fruiting can enhance leaf function, leaf thickening and weight gain, chlorophyll content increased by 15.9% 41.2%; (4) Fructus Przewalski can inhibit the scab damage on the fruit, reducing the rate of disease 10.3% ~ 11.0%.
