施肥对于提高农作物产量和品质有着显著的促进作用,施肥量的多少对农作物产量呈现一定的关系。并不是施肥越多,农作物产量越高。施肥量的多少应该结合立地条件和农作物需肥情况综合确定。现阶段,我国农业生产过程中提倡少施肥,精准施肥减少环境污染,提高肥料利用率,减少肥料在土壤的流失,防止土壤的板结。在生产过程中,选择使用缓释肥对提高肥料利用率有着显著的促进作用。为进一步验证“金正大”缓释肥料在油菜作物上稳产增产、省工省肥等方面的效果,本次研究在赤壁市“双低”油菜区进行了缓释肥效果试验示范,希望通过本次研究对更好提高农作物产量和品质,提高肥料利用率有一定促进作用。
Fertilization has a significant role in promoting the yield and quality of crops, and the amount of fertilizer exerts a certain relationship with crop yield. Not more fertilizer, the higher the crop yield. The amount of fertilizer should be combined with site conditions and crop demand for fertilizer comprehensively determined. At this stage, China’s agricultural production process to promote less fertilization, precision fertilization to reduce environmental pollution, improve fertilizer utilization, reduce fertilizer loss in the soil, to prevent soil compaction. In the production process, the choice of slow-release fertilizer to improve fertilizer utilization has a significant role in promoting. In order to further verify the effect of “Kim Jongda” slow-release fertilizer on the yield stability of rapeseed crops and provincial fertilization, this experiment conducted a demonstration of the effect of slow-release fertilizer experiment in the “double low” rapeseed area in Chibi City It is hoped that this study will have a certain promotion effect on improving crop yield and quality and improving fertilizer utilization rate.
