摘要: 为了探索适宜糖用甜菜高产优质种植的氮磷钾最佳施肥效应模型,本文以糖用甜菜为研究对象,采用大田回归组合试验,对糖用甜菜栽培中的氮、磷、钾肥因子与糖用甜菜的产量和品质的关系进行研究,采用层次分析法(Analytic Hierarchy Process, AHP)确定了各品质指标(糖度、钾、钠、a-氮)和产量为指标的权重,通过隶属函数对各种施肥处理糖用甜菜的产量和品质进行模糊综合评价,根据评价得分为品质指数初步建立并优化了氮、磷、钾肥因子与糖用甜菜综合品质指数的回归方程。结果表明:大田试验适宜的氮肥施用量为68.89~88.61 kg.ha-1,施磷量为47.94~92.06 kg.ha-1,施钾量为54.34 ~100.66kg.ha-1。

Abstract: To explore the optimal fertilization model of nitrogen, phosphorus and potassium for high yield and good quality of sugar beet, we took sugar beet as the research object and adopted the field regression experiment, to study the relationship between N, P and K factors in sugar beet cultivation and yield and quality of sugar beet, determine the weight of each quality index (brix, K, Na, a-N) and yield by Analytic Hierarchy Process (AHP), and evaluate the yield and quality of all kinds of sugar beet by membership function, and preliminarily establish and optimize the regression equation of N, P, K factors and the comprehensive quality index of sugar beet. The results showed that: the suitable N, P, K application amount was 68.89-88.61 kg/hm2, 47.94-92.06 kg/hm2, 54.34-100.66 kg/hm2 by optimal fertilization of N, P and K based on sugar beet quality and yield index; the NPK fertilizer ratio was 1.13:1:1.11, which was an appropriate fit value in a specific area and should be adjusted according to the basic fertility of soil in the cultivated area.
