系统研究了氮硫肥对大蒜产量和品质的影响。结果表明，在河南省潮土区大蒜施硫以６０ｋｇ／ｈｍ２为宜；硫肥基施的综合效应优于追施和底施加追施处理。大蒜施用氮肥，一般蒜头增产１６．４％～３０．２％，蒜苔增产８．３％～２８．４％；大蒜经济合理施氮量范围为１９３．２～３２８．６５ｋｇ／ｈｍ２，此时大蒜产量在１７７４０．２ｋｇ／ｈｍ２以上。氮硫配施比对照平均增产３８．７％，呈显著的正交互作用，３个试验点的交互值分别为１２６、２４９和１４８．５ｋｇ／ｈｍ２。
The effects of nitrogen and sulfur fertilizers on the yield and quality of garlic were systematically studied. The results showed that applying sulfur to 60 kg / hm2 was the best in shady soil in Henan Province. The comprehensive effect of basal application of sulfur fertilizer was superior to top dressing and top dressing. The application of nitrogen fertilizer to garlic, general garlic yield 16.4% ~ 30.2%, garlic yield 8.3% ~ 28.4%; garlic economic and reasonable amount of nitrogen range 193.2 ~ 328.65kg / hm2, garlic Output above 17740.2kg / hm2. Compared with the control, nitrogen and sulfur fertilizers increased the average yield 38.7%, showing a significant positive interaction, the interaction values of the three test points were 126,249 and 148.5kg / hm2 respectively.
