The stable production technology for creased satsuma mandarin

本研究旨在开发风味优良的温州蜜柑皱果型“喜食柑”的稳定生产技术。为此，研究了基于TDR产量变化的累积水分胁迫指数与皱果发生的关系。试验在不同土壤干燥程度的商品果园中进行了三年。结果表明，适宜的载果量、透水膜覆盖、按建议指标进行灌溉管理和辅以乙烯利是皱皮温州蜜柑稳产的重要条件。

The objective of this study is to develop the stable production techniques for'Kikumikan',creased fruit of Satsuma mandarin, with good taste. For this reason, the accumulated water stress index based on TDR output changes was investigated in relation to the creased fruit occurrence. The experiment was conducted in commercial orchards with different degree of desiccation in soil for three years. The important conditions to produce the creased Satsuma mandarin stably were summarized as follows, trees with adequate fruit load, water vapor permeable sheet mulching,irrigation management with the proposed index and the auxiliary use of ethyclozate.
