高效尿素系江苏省农科院土肥所研制的尿素新品种，与普通尿素相比，具有缓释、抑制脲酶活性，减少氨挥发和硝化—反硝化损失等特点，使作物对氮素的利用率提高２０％～２５％，此外还能为作物提供多种微量元素。为了加速高效尿素在句容的推广应用，１９９９年春我们在小麦上作
High-efficiency urea Jiangsu Provincial Academy of Agricultural Sciences soil fertilizers developed urea new varieties, compared with ordinary urea, with a slow release, inhibition of urease activity, reduce ammonia volatilization and nitrification - denitrification losses and other characteristics of crop nitrogen utilization Increase 20% ~ 25%, in addition to providing a variety of trace elements for crops. In order to accelerate the promotion and application of high-efficiency urea in Jurong, we made the wheat in spring 1999
