一种叫“N-Sever”的新产品(Nitrapyrin硝酸嘧啶),自从它开始投入工业生产就得到多方注意。这种产品使氮肥的损失得以停止。 我们希望对产品作一观察,它是怎样制作的以及是怎样被使用的?实际上,N-Sever仅是几种为减少氮肥损失而设计的产品中的一种。不过,我们将限制我们对N-Sever的讨论,因为它比任何其它产品更广泛地使用于农作物。但这不意味着我们是保证N-Sever或是排斥相同性质的其他产品。 A new product called Nitrapyrin Nitraterin has garnered a lot of attention since it started its industrial production. This product stops the loss of nitrogen fertilizer. We want to make an observation of the product, how it is made and how it is used. In fact, N-Sever is just one of several products designed to reduce nitrogen loss. However, we will limit our discussion of N-Sever because it is more widely used on crops than any other product. But that does not mean that we are guaranteeing N-Sever or other products that exclude the same qualities.
