在作物栽培中,施用的氮素肥料有很多种类,但能被作物吸收利用的最终形态除豆科作物之外,主要是硝态氮和氨态氮两种。因此,对作物生育来说,是使用硝态氮肥有利,还是氨态氮肥更有利,长期以来,一直是人们争论的一个问题。众所周知,作物的种类不同,气温、光照,降水量等气象条件、旱地和水田等土壤水分条件以及土壤养分供给和土壤酸碱度等诸因素不同,作物所施用硝态氮肥和氨态氮肥所表现出来的效果是不同的。本文将对硝态氮、氨态氮与作物生长发 In crop cultivation, there are many kinds of nitrogenous fertilizers applied, but the final forms that can be absorbed and utilized by crops are mainly nitrate and ammonia nitrogen in addition to leguminous crops. Therefore, it is more advantageous to use nitrate nitrogen fertilizer or ammonia nitrogen fertilizer to crop growth, which has been a subject of debate for a long time. It is well-known that different crop types, meteorological conditions such as temperature, light and precipitation, soil moisture conditions such as dry land and paddy fields, soil nutrient supply and soil pH value are all different. The nitrate nitrogen and ammonium nitrogen fertilizers The effect is different. This article will nitrate nitrate, ammonia nitrogen and crop growth
