【摘要】 为调查扁核酸的果吊比与微量元素之间的关系,在濮阳选取了21棵扁核酸枣树的枝条做了喷施钾、锌、氮、铁、镁、磷、钙等元素的试验,并调查了枣树的果吊比,通过设定的正交试验进行了微量元素与果吊比的关系分析,得出:钾、铁、磷、钙与果吊比呈负相关;锌、氮、镁与果吊比呈正相关且影响程度为镁﹥锌﹥氮。更多还原

【Abstract】 To investigate the relationship between jujube fruit hanging ratioand traceelements, we selected 21 branches of jujube trees in Puyang did the spraying of potassium,nitrogen,iron,zinc,magnesium, phosphorus,calcium andotherelementofthe test,andsurvey the jujube fruit hanging. Orthogonal test analysis of traceeleme ntsand fruit set of hanging ratio,weobtain: potassium, iron,phosphorus, calcium and negatively correlated wit hthe fruithanging; zinc, nitrogen, magnesium and fruit hanging ratios werepositively related and influence ofmagnesium﹥zinc﹥nitrogen.更多还原
