摘　　要：本论文主要研究台湾青枣施肥试验,旨在通过多种方法的肥料营养配比实验,并经过长时间的精心观察、调整,实验分析对比,找出最合理的营养配比,即青枣茁壮成长和速生丰产必需元素的最佳配比结构。可指导种植地青枣的推广,使其成为地区结构调整、发展农村经济和农民增收的一个重要主栽品种。本试验采用正交试验方法,共有16种施肥处理,通过对台湾青枣叶片的氮、磷和钾营养元素的分析对比,得出台湾青枣6-9月期间,施用氮肥27.3g,磷肥5.89g,钾肥31.95g,可使植株中的含氮量变化显著;施用氮肥27.45g,磷肥2.95g,钾肥15.97g,可使植株中的含磷量和含钾量变化显著。并利用数理统计回归分析建立了针对台湾青枣的初步施肥模型。The present paper mainly studies in the Taiwan blue jujube fertilization experiment, aims to use many kinds of fertilization nutrition allocated proportion experiment, and after the long time careful observation,adjustment, and the experiment analyzes the contrast, discovers the most reasonable nutrition allocated proportion, namely find the essential element best allocated proportion structure which can make blue jujube grows healthy, strong and the fast-growing bumper crop. May instruct the planter blue jujube the promotion, causes it to become the mainly plant which develops the local structure adjustment, rural economy and the farmer additionally incomes. This experiment uses the orthogonal testing method, altogether has 16kinds to apply fertilizer processing, through contrast analysis of the Taiwan blue jujube leaf blade's nitrogen, phosphorus and potassium nutritive elements, obtains the best fertilization amounts of Taiwan blue jujube in period of June and September, the conclusion is: the Taiwan blue jujube Plants in earth, nitrogenous fertilizer 27.3 grams per plant, phosphorus fertilizer 5.89 grams per plant, potassium fertilizer 31.95 grams per plant, can obviously elevate the nitrogenous percentage in Zizyphus mauritiana Lam leaf; And nitrogenous fertilizer 27.45 grams per plant, compound fertilizer 2.95 grams per plant, potassium fertilizer15.97 grams per plant, can obviously elevate the phosphorus and potassium percentage in Zizyphus mauritiana Lam leaf. In virtue of the mathematical statistic theory to establish the preliminary fertilization model of the Taiwan blue jujube。
