自从在农业生产上推广应用化学肥料以来,农民们最钟情的是氮素化肥,当农作物叶片发黄或者生长滞缓时,施用氮素化肥后,作物生长很快提速,叶色较快地转绿,能够起到立竿见影的效应,因此,氮肥的销售数量在化肥的市场营销份额中是遥遥领先的。但是,人们在施用氮素化肥的过程中,常常因为对氮素化肥的品种的特点认识不够或者技术上操作不当,给农业生产造成不应该发生
Since the promotion of the application of chemical fertilizers in agricultural production, the most favored farmers are nitrogenous fertilizers. When the crop leaves are yellowed or the growth is stagnant, the crop growth is rapidly accelerated and the leaf color is rapidly turned Green, can have an immediate effect, therefore, the number of nitrogen fertilizer sales in the fertilizer market share is far ahead. However, in the process of applying nitrogenous fertilizers, people often do not know enough about the characteristics of the varieties of nitrogenous fertilizers or they do not know how to handle them properly, which should not cause agricultural production.
