摘　　要：通过不同施肥量对稻田免耕油菜农艺性状、经济性状及产量的影响效应的研究试验结果表明,在铜仁市中等土壤肥力条件下,氮肥、磷肥和钾肥配比为2∶1∶2的情况下,氮肥统筹为180 kg/hm2,其中50%于苗期和抽薹期追施是提高肥料的利用效率、改善免耕油菜群体结构、促进养分积累、提高粒重、兼顾产量和效益的优化处理。The no-tillage rape was tested to study effects of different application mount on its growth characteristic and yield. The results showed that the optimum yield and economic benefit could be obtained by taking 25% of N as seedling fertilizer and 25% of N as dressing in bolting stage under the moderate soil fertility, N, P and K ratio of 2 ： 1 ： 2 and total N application amount of 180kg/hm^2.
