柑桔园铁锌营养及配方施肥模型研究

STUDIES ON Fe Zn NUTRIENTIN CITRUS ORCHARDS AND THEMODEL OF FORMULARY FERTILIZATION

采用五因素五水平二次回归最优旋转设计，对柑桔园铁锌营养及配方施肥模式进行了研究，并建立了碱性紫色土和中性紫色土温州蜜桔、锦橙，以产量为主要指标和黄红壤冰糖橙以叶片锌含量为主要指标的推荐施肥模式及参考施肥配方。

Fe,Zn nutrient in citrus orchards and the model of formulate fertilization had been studied with 5factor5level orthogonal rotation design. The main models had been established, which are: 1.The fertilization model and reference fertilization formulary of Satsuma based on yield recommended as a major index in alkaline purple soil; 2.The fertilization model and reference fertilization formulary of Jinchen orange based on yield recommended as a major index in neutral purple soil; 3.The fertilization model and reference fertilization formulary of Bintang orange based on leaf Zn content recommended as a major index in acid redyellow soil.
