摘要
合理施用硫肥可以提高作物产量、改善作物品质,但在国内生姜主产区增施硫肥对产量的影响鲜见报道。本试验通过对生姜进行不同的增施硫肥处理,然后从生姜的部分植物学特征及产量等方面进行较为详细的分析。结果表明：生姜增施硫肥可以不同程度地改善其生育性状,叶色绿,茎杆粗壮,后期抗早衰,干叶尖降低,株高、茎粗、分枝数增加。同时,可以提高产量产值,高产地块亩增产率0.9%~6.6%,投入产出比在1：28.6~1：59.7;中产地块增产率为0.4%~4.6%,投入产出比达1：9.3~1：26.6。增施硫肥可以不同程度地促进生姜生育性状,并且能够提高其产量产值。
Reasonable application of sulfur fertilizer could increase crop yield and improve crop quality, but itseffect on the yield of ginger was seldom reported. The botanic character and yield of ginger were analyzed bythe application of different rates of sulfur fertilizer. The results showed that the application of sulfur fertilizercould improve reproductive traits of ginger in different degrees, which could keep green leaf, strong stem andresist premature senility in the later period, reduce the late of stem tip and increase plant height, stem diameterand branch number. At the same time, the application of sulfur fertilizer could improve the production andoutput value of ginger, which could increase the yield by 0.9%-6.6%, the input-output ratio was 1：28.6-1：59.7. The growth rate in middle yield block was 0.4%-4.6%, and the input-output ratio was 1：9.3-1：26.6. Theapplication of sulfur fertilizer could promote the reproductive traits of ginger in different degrees, and improveits production and output value.
