为明确油菜(Brassica napus L.)专用肥对鄂中地区直播油菜产量的提升效果,于2019-2021年在湖北省沙洋县开展了连续2年的田间试验,设置了不施肥、常规施肥、宜施壮专用肥和洋丰专用肥4个施肥处理,考察各处理下成熟期油菜产量、地上部生物量、地上部养分含量、地上部养分积累量以及肥料偏生产力等的差异.结果表明,与不施肥对照相比,常规施肥和专用肥处理均能显著提高油菜子产量;与常规施肥相比,专用肥处理总养分投入减少了41.3％,而两者油菜子产量无明显差异.施肥显著增加了油菜地上部生物量,促进了油菜地上部对养分的吸收.油菜专用肥处理显著提高了肥料偏生产力,与常规施肥处理相比,宜施壮专用肥和洋丰专用肥处理平均肥料偏生产力在2019-2020年、2020-2021年分别提高了80.6％和68.2％.综上所述,油菜专用肥在保障油菜高产稳产的同时,提高了肥料利用率.
Effect of special fertilizer for oilseed rape in Central Hubei Province
To clarify the effect of special fertilizers for oilseed rape(Brassica napus L.)on the yield enhancement of direct seeding oil-seed rape in central Hubei Province,field experiments for two consecutive years in Shayang County,Hubei Province from 2019 to 2021 were carried out,with four fertilization treatments of no fertilizer,conventional fertilizer,Yishizhuang special fertilizer and Yangfeng special fertilizer,and the differences of the yield,aboveground biomass,aboveground nutrient content,aboveground nutri-ent accumulation and fertilizer partial productivity of oilseed rape at mature stage under four treatments were analyzed.The results showed that compared with no fertilization control,both conventional fertilization and special fertilizer treatments could significantly in-crease rapeseed yield.Compared with the conventional fertilization,the total nutrient input of the special fertilizer treatments de-creased by 41.3％,but there was no significant difference in rapeseed yield between conventional fertilization and special fertilizer treatments.Fertilizer application significantly increased the aboveground biomass of oilseed rape and promoted the absorption of nutri-ents by the aboveground oilseed rape.The treatment with special fertilizer for oilseed rape significantly improved the partial productivi-ty of fertilizers.Compared with the conventional fertilization treatment,the average fertilizer partial productivity of Yishizhuang special fertilizer treatment and Yangfeng special fertilizer treatment increased by 80.6％and 68.2％respectively in 2019-2020 and 2020-2021.In conclusion,the special fertilizer for oilseed rape improved the utilization rate of fertilizer while ensuring a high and stable yield of oilseed rape.
