氮肥增效剂是一种硝化抑制剂。和氮肥配合施用,可以抑制硝化微生物对铵态氮的硝化作用,减少氮肥流失,提高肥料利用率。茶叶生产中目前多以施铵态氮和(月先)胺态氮的化学氮肥为主,其中一部份在土壤中转化为硝态氮而被淋溶损失。从试验中可以看出就鲜叶氨量估计,其氮肥利用率只有50％左右。为提高肥料利用 Nitrogen synergist is a nitrification inhibitor. And nitrogen fertilizer with the application, can inhibit the nitrification of nitrification of ammonium nitrogen, reduce nitrogen loss and improve fertilizer utilization. At present, the production of tea leaves is dominated by chemical nitrogenous fertilizers, ammonium nitrogen and (monthly) amine nitrogen, and some of them are converted to nitrate nitrogen in soil and leached. It can be seen from the test on fresh leaf ammonia estimates, the utilization rate of nitrogen fertilizer is only about 50%. To improve fertilizer use
