小麦是世界上总产量最多,营养价值最高的粮食作物之一,是北方的主要粮食作物。随着生产条件的改变,小麦的产量水平有所提高。随着农业的发展,中国的化肥施用量逐年增长,我国的化肥消费量从1980年的1269万t增加到2011年的6027万t。长期实践表明,施肥作为一种调控产量的有效手段,同时也可在有限的条件下对作物品质给以必要的调控,我们选择锰与氮、钾作为研究因子,
Wheat is one of the world’s most productive cereals with the highest nutritional value and is the main food crop in the North. With changes in production conditions, the level of wheat production has increased. With the development of agriculture, the application of chemical fertilizer in China has been increasing year by year. The consumption of chemical fertilizers in China increased from 12.69 million tons in 1980 to 60.27 million tons in 2011. Long-term practice shows that fertilization as an effective means of yield control, but also under the limited conditions of crop quality to give the necessary regulation, we choose manganese and nitrogen, potassium as a research factor,
