- 摘要:
- 阐述了脲酶抑制剂氢醌对土壤中的尿素NH3挥发有抑制作用, 延缓尿素水解速率。氢醌对脲酶抑制是有时间性的, 随着时间延长抑制作用逐渐减弱, 而土壤中的脲酶活性在一定时间内能自然恢复, 有一定的保氮作用。脲酶抑制剂氢醌与氮磷钾混拌, 促进了小麦氮的吸收效率, 提高氮肥利用率, 明显的改善了小麦的产量结构。
- Abstract:
- U rea inhibitor HQ can retard urea hy drolysis rate and loss of ammonium to air by volatilization .HQ possesses timeliness to urease inhibi tion , that inhibi ting effect decreases g radually wi th timepassing.So applying HQ mixed wi th N , P ,K fertilizer increased abso rption of w heat to nit rogen , increasedutilization rate of urea , and improved st ructure of product obviously .
