摘要: 设置6个不同硫酸钾钙镁肥用量(0、375、750、1 125、1 500、1 875 kg/hm2)处理,研究其对油菜(Brassica napus L.)产量和经济效益的影响。结果表明,施用硫酸钾钙镁肥不仅有助于提高油菜产量,且对于提高油菜的经济效益也有一定作用。与对照(NPB)相比,连续两年(2016—2018年)施用硫酸钾钙镁肥处理油菜产量分别增加20.1%~42.3%和27.0%~58.7%,当施硫酸钾钙镁肥量分别为1 182 和1 167 kg/hm2时油菜产量达到最高产量,分别为3 234和2 438 kg/hm2。与对照(NPB)相比,连续两年均是硫酸钾钙镁肥用量为375 kg/hm2时,油菜的经济效益最高,纯利润分别为852和661元/hm2。建议硫酸钾钙镁肥在油菜上的适宜施用量为375 kg/hm2

Abstract: Six different polysulphte fertilizer treatments(0,375,750,1 125,1 500,1 875 kg/hm2) were set up to study the effects of different polysulphte fertilizers on the yield and economic benefits of rape(Brassica napus L.). The results showed that compared with the control(NPB), the application of polysulphte fertilizer for two consecutive years(2016—2018) increased the yield by 20.1%~42.3% and 27.0%~58.7%, respectively. The highest yield were achieved at 1 182 and 1 167 kg/hm2, respectively, with maximum yield of 3 234 and 2 438 kg/hm2, respectively. Compared with the control(NPB), the economic benefit of rape was the highest when the dosage of polysulphte fertilizer was 375 kg/hm2 for two consecutive years, which were 852 and 661 yuan/hm2, respectively. The application of polysulphte fertilizer not only helped to increase rape yield, but also had a certain effect on improving the economic benefits of rape. It is suggested that the suitable application rate of polysulphte fertilizer on rape is 375 kg/hm2.

Key words: application amount of polysulphte fertilizer, rape(Brassica napus L.), yield, economic benefit
