| 摘 要： | 为解决江苏省沿江地区冬油菜氮磷钾肥量合理用量的问题，以扬州市江都区2012—2013、2013—2014、2014—2015年连续3年氮、磷、钾肥不同肥料用量为试验材料，采用肥料效应函数模型对冬油菜施肥指标体系进行研究。发现合理施用氮磷钾肥对油菜主要农艺性状有促进作用，同时能显著提高油菜的产量；确定了江都区种植冬油菜氮肥推荐量为277~308 kg/hm2，平均为292.5 kg/hm2；磷、钾肥适宜推荐量分别为70、98 kg/hm2，为江苏省沿江地区种植冬油菜提出了合适的施肥建议。

| Abstract: | In order to solve the problem of the reasonable amount of N, P and K in winter rapeseed along the Yangtze River in Jiangsu Province,based on N, P and K fertilizers with different dose in 2012-2015 years of Jiangdu district in Yangzhou City, the study was conducted about the fertilization index system of winter rapeseed by using the fertilizer effect function model. The results showed that the rational N, P and K fertilizers could increase the growth of rapeseed, and increase obviously yield of rapeseed. Using Single-factor and linear plus platform model, the optical recommendation of N fertilizers were 277-308 kg/hm2, with average 292.5 kg/hm2, and the optical recommendation of P, K fertilizers were 70 kg/hm2, 98 kg/hm2, respectively. These were improvement for fertilization index system for rapeseed in the area along the Yangtze River in Jiangsu province. |
