| 摘 要： | 试验表明,在土壤偏碱性,有效58.75mg/kg条件下,玉米作物施硫具有显著的增产、增值效果。施硫对提高单位面积有效穗数、平均穗籽粒数、千粒质量、叶色深度具有显著的影响,对生育时段影响较小,增产、增值效应随用量不同而异,增产9.33～26.83kg/667m~2,平均产量19.29kg/667m~2,增产率5.76%～16.59%,投产比10.17～4.32,合理用量为纯硫。2.00～4.00kg/667m~2,做底肥施用。

| Abstract: | In this paper,experiments showed that the soil alkaline,effectively 58.75 mg/kg conditions,the maize crop sulfur signi cantly increase production,value-added effect.S applied to improve the effective panicles per unit area,the average spike grain number,grain weight,color depth has a signi cant impact.Little effect on the growth period,yield,with a multiplier effect varies with the amount,By 9.33～26.83 kg/667 m～2average 19.29 kg/667 m2,5.76%～16.59% yield,production than 10.17～4.32,reasonable amount of pure sulfur 2.00～4.00 kg/667 m～2,as base fertilizer.As base fertilizer. |
