In addition,applying nitrification inhibitors could increase vitamin C and soluble sugar contents in pakchoi,and promote N and P uptakes by pakchoi.

另外，3种硝化抑制剂还能显著提高小白菜的维生素C和可溶性糖含量，增强对N，P养分的吸收。

Then, N-(5-nitro-6-chloro-3-pyridinemethyl) phthalimide is obtained after the nitrating reaction of N-(6-chloro-3-pyridine methyl) phthalimide. The yield of the obtained product is 90.5%, and its melting point is 143.1~143.8℃.

缩合产物再经过硝化，合成N-（5-硝基－6-氯－3-吡啶甲基）邻苯二甲酰亚胺，其熔点为143.1~143.8℃，收率为90.5%。

Here we describe a gene in the plant pathogen Streptomyces turgidiscabies that encodes a NOS homologue, and we reveal its role in nitrating a dipeptide phytotoxin required for plant pathogenicity.

作者描述了植物致病菌Streptomyces turgidiscabies中一种编码NOS同源物的基因并揭示了其在植物致病性中所需的对植物毒素二肽的硝化作用。
