玉米作为黑龙江省的旱田作物之一,随着近年来我国生产力的不断提高,玉米在产量上有了大幅度的提高,且玉米对氮素的需求量比其他肥料的需求量更高,具有较强的耐肥性,通过施撒氮肥可有效提高总体产量。科学合理的施撒氮肥有利于增强对氮肥的利用效果,减少对生态环境的破坏。基于此,通过对黑龙江省的玉米对氮素的吸收与积累研究,为如何实现科学合理的使用氮肥,提供了一定的理论基础与科学依据。
As one of the dryland crops in Heilongjiang Province, with the continuous improvement of productivity in recent years, the output of maize has been greatly increased, and the demand for nitrogen in maize is higher than that of other fertilizers. Strong resistance to fertilizer, through the application of nitrogen fertilizer can effectively improve the overall yield. Scientific and rational application of nitrogen fertilizer is conducive to enhancing the use of nitrogen fertilizer to reduce the damage to the ecological environment. Based on this, through the study on the absorption and accumulation of nitrogen in maize in Heilongjiang Province, this study provides some theoretical and scientific evidences for how to use nitrogen fertilizer in a scientific and rational way.
