油菜施硫效应的研究

Effect of Sulphur Fertilizers on Rapeseed

通过田间小区试验，比较了湖北红壤中施用硫磺、石膏和澳大利亚颗粒复合肥对油菜生物量、籽实产量和油菜籽品质的影响．试验结果表明，在正常施用氮、磷、钾的情况下，配合施用硫肥对油菜有明显的促进效应，其中澳大利亚颗粒复合肥和石膏的效果显著，有推荐使用的价值．

Field trials were conducted to investigate the effects of sulphur fertilizers including elemental sulphur, gypsium and Australia sulfur —containing compound fertilizer on rapeseed in red soils. The sulphur addition increased the fresh weight, dry weight and yield of rapeseed. The average order of biomass production was NPK+A>NPK+G>NPK+E.The sulphur fertilizers also improved the characteristics of fatty acid in seed. At same time analysed the S content of whole rapeseed plants and extractable soil S before and after the rapeseed crop.
