为给金川区菜心生产中合理施肥、节本增效提供依据，在金川区供港蔬菜基地进行田间试验，以菜心品种杂交尖叶80为指示品种，设置生物有机肥3 000 、6 000 kg/hm2分别替代化肥减量20%、30%处理，以不施肥为对照，研究生物有机肥替代部分化肥对菜心产量和效益的影响。结果表明，化肥减量20%+生物有机肥 3 000 kg/hm2处理的菜心产量最高，为12 296.40 kg/hm2，较不施肥处理增产3 112.65 kg/hm2，增产率为33.89%；经济效益最高，为70 806.60元/hm2，较不施肥处理节本增效12 012.25元/hm2。建议在当地菜心生产中采用，以实现菜心稳产增收。

To provide reference for the rational fertilization and cost-saving management in the production of Chinese flowering cabbages in Jinchuan District, this study was conducted in the vegetable base of Jinchuan District to study the effects of chemical fertilizer reduction combined with biological organic fertilizer on yield and economic benefit of Chinese flowering cabbage production. Taking Zajiao Jianye 80 as the indicative variety and no fertilizer treatment as the control, treatments of chemical fertilizer reduction 20%+3 000 kg/ha organic fertilizer, chemical fertilizer reduction 30%+6 000 kg/ha organic fertilizer etc. were set up. Results showed that yields peaked at treatment of chemical fertilizer reduction 20%+3 000 kg/ha organic fertilizer, which was 12 296.40 kg/ha and was 31 123.65 kg/ha higher compared with that of the control, the yiled increase rate was 33.89%, its economic benefit was also the highest which was 70 806.60 RMB/ha which saved the production cost by 12 012.25 RMB/ha compared with that of the control, therefore this treatment is recommend for local Chinese flowering cabbage production to achieve steady yield and higher economic return.
