喷施叶面肥对塔罗科血橙果实色泽的影响
Effect of foliar fertilizer application on Tarocco blood orange coloration
摘要
Abstract
[Objective]This research studied the different Tarocco blood orange (Citrus sinensis(L.) Osbeck.)col-oration effects after spraying the fruits with different concentrations of foliar fertilizer in order to provide reference for fruit cultivation and fruit color improvement. [ Method ] Using the L9(34) orthogonal experimental designed foliar fertilizers (potassium fertilizer+ calcium fertilizer+ boron fertilizer+ zinc fertilizer) to spray on plants during the coloration turning period, the fruit color changes were regularly measured and the main factors affecting the foliar fruit color index were analyzed and compared. [Result]The effect of boron fertilizer had maximum effect on the fruit color, followed by the effect of zinc fertilizer; the effect of calcium fertilizer had minimal effect. The effect of boron fertilizer on the a/b color value, brightness, and color saturation reached exceptionally significant level. As the boron fertilizer concentration increased, the a/b color value first decreased then increased, whereas the brightness and color saturation first increased then decreased. The effect of zinc fertilizer on a/b color value reached extremely significant level; the a/b color value increased as the zinc fertilizer concentration decreased. [Conclusion]During the color transferring period of Tarocco blood orange, the fruit coloring effects of boron and zinc fertilizers were better than those of potassium and calcium fertilizers. Different types and concentrations of foliar fertilizers had varying effects on the improvement of Tarocco blood orange fruit coloring.关键词
