水田土壤施用氮肥常发生随水流失和微生物转化,致使氮素肥分损失而降低了肥效。随着施肥方法的不同,水稻对氮肥的吸收利用和氮素肥分的损失程度也不相同,采用科学的施肥方法是降低肥分损失,增加作物吸收利用的重要途经。在这方面,我省广大贫下中农和革命科技人员积累了较为丰富的实践经验。例如将
Paddy soil application of nitrogen often occurs with the loss of water and microbial transformation, resulting in loss of nitrogen fertilizer and reduce fertilizer efficiency. With the different fertilization methods, the absorption and utilization of nitrogen and the loss of nitrogen fertilizers are not the same. The scientific fertilization method is an important way to reduce the loss of fertilizer and increase the absorption and utilization of crops. In this regard, the vast majority of poor and middle-level peasants and revolutionary scientists and technicians in our province have accumulated rich practical experience. For example will
