摘要
比较储良广眼成花组与无花组叶片营养元素，观察到两组间Ca、Mg、Mn含量呈显著性差异。有利于成花的营养元素含量分别是Ca1．4×10×2．0×104（μg／g），Mg1．8×103～2．5×103（μg／g），Mn32～80（μg／g）。结合花前施肥补充Ca、Mg、Mn则可显著提高开花树的比例，本结果对提高储良广眼的产量具有重要现实意义。同时也观察到无花组K、P、Zn的含量与成花组无显著差异。
Nutrient elememts between the flower group and the floweless were compared.The results shaw that it differs greatly in the content of nutrient elements Ca, Mg, Mn in the leaf blade of Chuliang-Guangyan Longan.The contents which contributing to the floral formation are, in turn, Ca 1.4×104～ 2.0×104(μg/g), Mg1.8×103～ 2.5× 103(μg/g), Mn 32～80(μg/g). The proportion of the floral trees can be improved greatly by feeding Ca, Mg,Mn in purpose when fertilizing before the floral formation and it is good for improving the yield of longan .The content of the nutrient elerents K, P, Zn have less apparent differences between the flower group and the flowerless group in the flowerless group in the leaf blade of Longan.
