不同氮磷钾滴灌肥施用量对欧李果实品质产量的影响

Effect of Different Nitrogen, Phosphorus and Potassium Drip Fertilizer Application Rates on Quality and Yield of Cerasus Humilis

【目的】与传统施肥方式相比较,滴灌肥具有提高肥料利用率、施肥肥效快等诸多优势。本试验通过田间试验探索欧李需肥规律,分析氮磷钾元素不同的施用比例对欧李果实品质及产量的影响,为欧李的合理施肥制度提供科学的指导。【方法】本试验以两年生欧李为研究对象,采用单因素多水平随机区组设计,将氮、磷、钾施肥量分别设置7个施肥梯度,以不施肥处理CK为对照,探究不同梯度下氮、磷、钾滴灌肥对欧李果实品质和产量的影响。【结果】试验表明在氮、磷、钾肥施用量分别为283.95kg/hm^2、79.65kg/hm^2、122.25kg/hm^2时,可达到果实最高产量;在氮、磷、钾肥施用量分别为180kg/hm^2、120kg/hm^2、60kg/hm^2时,欧李果实品质等综合特性为最佳。

[Objective] Compared with traditional fertilization methods, drip irrigation has many advantages such as improving fertilizer utilization rate and applying fertilizer efficiency. In this experiment, the field experiment was conducted to explore the fertilizer requirement of Euphorbia, and the effects of different application rates of nitrogen, phosphorus and potassium on the quality and yield of Eucalyptus fruit were analyzed, which provided scientific guidance for the rational fertilization system of Euler.[Methods] In this experiment, two-year-old Eugene was used as the research object. The single-factor and multi-level randomized block design was used to set the fertilization amount of nitrogen, phosphorus and potassium to 7 fertilization gradients respectively. Effects of Nitrogen, Phosphorus and Potassium Drip Fertilizers on Fruit Quality and Yield of Cerasus humilis.[Results] The test showed that when the application rates of nitrogen, phosphorus and potassium fertilizer were 283.95kg/hm^2, 79.65kg/hm^2 and 122.25kg/hm^2, respectively, the highest yield of fruits could be achieved;the application rates of nitrogen, phosphorus and potassium fertilizers were 180kg/hm^2, 120kg/hm^2, 60kg/hm^2, the comprehensive characteristics of the fruit quality of Cerasus humilis are the best.
