摘　　要：以湘油420为试验材料,在永州市进行了田间试验,研究了化肥农药减施对直播油菜产量和种植经济效益的影响。结果表明:永州市直播油菜种植过程中,通过一次性施入缓释专用肥替代传统的施肥模式,采取新美洲星拌种及喷施、搭配使用盾壳霉及常规化学农药,可在化肥农药减量的基础上,有效提高油菜产量及种植经济效益。Xiangyou 420 was used as the experimental material in Yongzhou City to study the effect of fertilizer and pesticide reduction on the yield and planting economic benefit of direct sowing rapeseed.The results showed that in the process of direct seeding rapeseed planting in Yongzhou City,the one-time application of slow-release special fertilizer instead of the traditional fertilization mode,the use of New American Star seed dressing and spraying,combined with the use of pelletoides and conventional chemical pesticides,could effectively improve the yield and planting economic benefits of rapeseed on the basis of the reduction of chemical fertilizers and pesticides.
