推广应用叶分析指导柑桔生产,进行科学经济施肥,是夺取柑桔高产优质和提高经济效益的一个急待解决的课题。为此,我们于1983年至1986年采用全量速测法(为便于与常规全量分析相联系,并附行同一叶样的常规百分干重检测),对温州蜜柑进行不同施肥水平和叶片氮磷钾营养诊断的研究。现将4—5年的研究和观察结果总结于下:
Promote the use of leaf analysis to guide the production of citrus, scientific and economic fertilization, is to seize citrus high yield and quality and improve economic efficiency of an urgent issue. To this end, we used the full-rate method from 1983 to 1986 (in order to facilitate the conventional full-scale analysis associated with the same leaf samples of the conventional percentage of dry weight detection), Satsuma mandarin different fertilization levels and leaf nitrogen Phosphorus and Potassium Nutrition Diagnosis Research. Now 4-5 years of research and observations summarized in the following:
