增果灵在温州蜜柑上的应用研究

A Study on the Application of Zenguoling to Satsuma Orange

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 physiological,yielding and qualitative effects of Zenguoling on satsuma orange were investigated.The result showed that Zenguoling (1) Promoted the development of the fruits,decreased their abscission,increased markedly the fruit-setting percentage,increased the yield by 13.6 percent of more;(2) Improved markedly the quality of the fruit significantly,increased weight of each fruit by 13.6～14.7g,thinned the fruit skin,and at the same time enhanced the fruit surface,increased the contents of soluble solid substances and vitamin C;(3) Promoted leaf function,increased leaf thickness and weight,increased leaf chlorophyll content by 15.9～41.2 percent;(4) Effectively inhibited the harm by scab disease to the fruit,abated the rate of diseased fruit by 10.3～11.0 percent.
