Effect of Sulfur Fertilizer on Growth and Quality of Edible Amaranth
摘要
Abstract
[Objective] The optimal sulfur concentration for reducing nitrate accumulation content in edible amaranth was assured to provide guide for sulfur application. [Method] 4 sulfur level was set, pot test was carried out to determine plants′s growth,nitrate,Vc content. [Re-sult] Plant height,weight per plant,maximum leaf length and maximum leaf width were increased by applying sulfur fertilizer. The plant height was the highest when sulfur concentration was 20 mg/kg(S2),incerased by 14. 3% compared with no sulfur fertilizer treatment (S0). S1 ~S3 of nitrate content was decreased by 20. 6% -64. 7%. Nitrate content of plant in edible part was decreased by 64. 7% when sulfur concentra-tion was 10 mg/kg. VC content of sulfur treatment were increased by 19. 7% -28. 3%. [ Conclusion] Suitable sulfur concentration was 10-20 mg/kg for edible amaranth in field.关键词
