重庆市秀山县2014年9月至2015年5日,进行了油菜轻简施肥试验研究。结果表明,在保肥能力强的土壤上,油菜移栽后20~30天一道清施化肥,效果最好;而底肥一道清施化肥,有利于前中期营养生长,后期营养略欠缺,移栽后50天一道清施化肥,前中期营养生长差,后期营养充足,均不利获得高产。
From September 2014 to 2015, Xiushan County, Chongqing Municipality conducted a pilot study on simple and easy fertilization of rapeseed. The results showed that fertilizers applied in 20-30 days after rapeseed transplanting had the best effect on soil with strong fertility conservation. Fertilizing fertilizer together with base fertilizer was conducive to vegetative growth in the early and middle stages with slight lack of nutrients in the late stage and transplanting Fertilizers were applied after 50 days, with poor vegetative growth in the first half of the period and adequate nutrition in the later period, all of which adversely affected the yield.
