冬小麦要想获得高产,单靠土壤中的养分远不能满足小麦的生长发育的需要,因此必须增施肥料。长期以来,人们已充分认识到氮肥、磷肥的重要性,但对钾肥却一直未引起足够的重视,随着氮、磷的大量施用,小麦单产的提高,小麦生长所需要的钾素越来越多,而土壤速效钾含量又呈逐年递减趋势。因此钾已成为我地区部分小麦高
To get high yield of winter wheat, soil nutrients alone can not meet the needs of wheat growth and development, it is necessary to increase fertilizer. For a long time, people have fully realized the importance of nitrogenous fertilizer and phosphate fertilizer, but they have not given enough attention to potash fertilizer. With the large application of nitrogen and phosphorus, the increase of wheat yield and the increase of potassium required for wheat growth More, while available potassium content of soil showed a decreasing trend year by year. As a result, potassium has become part high in my area of wheat
