摘　　要：与养分相同的常规化肥进行对比,缓释肥能够明显增加作物产量,减少劳力的投入,同时也在一定程度上缓解了环境污染问题。玉米是全球范围内非常重要的粮食作物,它对于经济和工业的发展价值重大,表现出不可忽视的开发潜力。为了选出对该区域玉米最为适用的缓释肥施肥量,最大化提升作物产量,通过田间试验的方法探讨了山西晋谷复合长效缓释肥4种不同施肥量对玉米发育和产量产生的实际影响。最后得到的数据显示,施用缓释肥不但可在一定程度上改善玉米生长性状,同时还可以起到非常显著的增产效果。Compared with conventional chemical fertilizers with the same nutrients,slow-release fertilizers can significantly increase crop yield,reduce labor input,and also alleviate environmental pollution to a certain extent.Corn is a very important food crop in the world,which has great value for economic and industrial development,showing the development potential that can not be ignored.In order to select the most suitable fertilizer dose for corn in the region and maximize the crop yield,the field experiment method is used to investigate the effect of four different doses of Shanxi Jingu compound long-acting slow-release fertilizer on maize development and yield.Finally,the data show that the application of slow-release fertilizer can not only improve the growth characteristics to a certain extent,but also play a very significant role in increasing production.
