研究了高产小麦前氮后移的增产作用,指出这一技术与品种类型、土壤肥力、播种密度等条件有密切关系,在生产中运用前氮后移施肥技术必须与看苗管理、应变措施结合起来。
This paper studied the increase of nitrogen uptake after high yield wheat and pointed out that this technique is closely related to the variety type, soil fertility, planting density and other conditions. Before the application of nitrogen in the production, the technology of backward fertilization must be combined with seedling management and strain measures stand up.
