带状尿素水解时,会在土壤中产生一个高pH值和高浓度铵盐的区域,这将导致庄稼幼苗和硝化细菌的氨中毒。这些细菌如果受到感染,就不能正常地将亚硝酸盐转化成硝酸盐,因此亚硝酸盐就会积累起来。这又导致脱氮作用的加强和氮肥的损失。延缓尿素水解时间将减少上述问题。加拿大McGill大学研究人员研究 When zonal urea hydrolyzes, it generates a region of high pH and high concentrations of ammonium salts in the soil that will lead to ammonia poisoning of crop seedlings and nitrifying bacteria. If these bacteria become infected, nitrite can not be converted normally to nitrate, so nitrite accumulates. This, in turn, leads to enhanced denitrification and loss of nitrogen fertilizers. Delaying the urea hydrolysis time will reduce the above problems. Researcher at McGill University in Canada
