| 摘 要： | 田间试验表明:施用尿素时,每次添加100—150g脲酶抑制剂(氢醌和醌氢醌),尿素在土壤中水解速度减慢,肥效期延长,可提高尿素利用率4％—6％,每亩减少尿素用量5—10kg,增加了经济收入.

| Abstract: | The results of field experiments showed that applying urea supplied with urease inhibitors (p-dihydroxy benzene and quinhydrone) at 100— 150 g/ mu decreased the hydrolytic rate of urea in soil and the period of fertilizer efficiency was prolonged. In treatments, the utilized coefficient of urea was increased by 4%-6% and the amount of urea applied was reduced by 5-10 kg per mu, therefore, the economic returns were raised. |
