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。
Experiments show that in the soil alkaline, effective 58.75mg / kg conditions, corn crop sulfur has a significant increase in yield and value. Sulfur application had a significant effect on increasing effective panicles per panicle, average number of spike kernels per panicle, grain weight per panicle, leaf color depth and had little effect on the growth period. The effects of increasing yield and increasing value varied with the amount of application, increasing 9.33 ~ 26.83 kg / 667m ~ 2, the average yield is 19.29kg / 667m ~ 2, the yield increase rate is 5.76% ~ 16.59%, and the production ratio is 10.17 ~ 4.32. 2.00 ~ 4.00kg / 667m ~ 2, make base fertilizer application.
