由中国科学院林业土壤研究所土壤肥力研究室研制的长效尿素是一种加脲酶抑制剂氢醌的尿素.通过三年室内模拟、盆栽及田间试验,该研究室研制人员在多种抑制剂中筛选出了经济、高效、无毒并有应用前景的氢醌,在抑制尿素分解,提高尿素利用率和减少肥料损失等方面具有明显的作用,并研究了提高作物产量的适宜氢醌浓度和施用方法.研究结果表明,使用加氢醒的尿素,具有节省劳力、增加产量、节省肥料、对土壤和植
The long-acting urea developed by the Soil Fertility Research Laboratory of the Institute of Forestry and Soil Science, Chinese Academy of Sciences, is a urea with urease inhibitor hydroquinone.Through three years of indoor simulation, potted plants and field experiments, the laboratory researcher in a variety of inhibitors The economic, efficient, non-toxic and promising hydroquinone has been screened out to have obvious effect on inhibiting urea decomposition, improving urea utilization rate and reducing fertilizer loss, and the suitable hydroquinone concentration for improving crop yield and application The results of the study show that the use of hydro-awakening of urea has the advantages of labor saving, increased yield, fertilizer savings, soil and plantation
