摘要
通过对宜昌夷陵区雷家畈村不同产量金魁猕猴桃叶片营养状况的调查与分析,得出P、Ca、Cu、Zn、Mo为影响猕猴桃园果实产量的主要元素;当地猕猴桃园叶片严重缺乏Ca、Fe,部分果园缺乏N、Mg,P、Cl含量丰富。Fe-Zn-Mo之间、N与Fe之间存在相互协助关系,Fe与Cu之间存在相互拮抗关系。Fe与Zn、Mo的关系符合逻辑斯特模型,Mo与Zn、Cu的关系分别符合Richards和二次曲线模型,Fe与Cu关系符合韦布尔函数,Cl与K和Mg关系分别符合多项式和JohnsonSchumacher模型。
Nutrition status in leaf of different yield Jinkui kiwifruit orchards was conducted in Leijiafan village of Yiling district, Yiehang. P, Ca, Cu,Zn and Mo were primary elements of influencing kiwifruit yield in local orchards. Ca and Fe in leaf were very low,N and Mg were low in part of orchards,P and CA were high. It was stimulative among Fe, Zn and Mo, between N and Fe, it was restraining between Fe and Cu. Seven pairs of elements adapted to different mathematic models.
