不同施肥模式对茎瘤芥产量及经济效益的影响

Effects of Different Fertilizer Modes on Yield and Economic Benefit of Tumorous Stem Mustard

为探索茎瘤芥绿色高效施肥技术,在余姚茎瘤芥主栽区域,研究了不同施肥模式对茎瘤芥农艺性状、产量、养分和经济效益的影响。结果表明,与常规施肥相比,在“配方肥+脲胺氮肥”化肥减量增效模式下,泗缩1号瘤茎产量3935.5 kg/667 m^(2),净收益2796.55元/667 m^(2),节本增效976.49元/667 m^(2),效益/成本达2.82,可减少肥料用量24%,提高作物产量25%以上,实现节本增效50%以上,提质增效明显,该施肥模式在规模化生产中具有较大推广应用价值。

In order to explore the green and efficient fertilization techniques of tumorous stem mustard,the effects of different fertilizer modes on the main agronomic traits,yield,nutrient and economic benefit of tumorous stem mustard were studied in the main planting area of Yuyao.The results showed that compared with the conventional fertilization,under the fertilizer reduction and efficiency increase mode of formula fertilizer+urea-ammonium mixed nitrogen fertilizer,the yield of tumorous stem mustard Sisuo No.1 was 3935.5 kg/667 m^(2),the net income was 2796.55 yuan/667 m^(2),the comprehensive reduce cost and increase efficiency was 976.49 yuan/667 m^(2),the benefit/cost was 2.82,the amount of fertilizer was reduced by 24%,the yield was increased by more than 25%,and the efficiency increase was above 50%.The quality and efficiency of tumorous stem mustard was improved significantly.This fertilization mode had great application value in large-scale production.
