摘要
近年来,由于作物单位面积产量不断提高,高产品种的引入和推广,氮、磷用量的增加,以及有机肥用量的减少,土壤钾素在逐步降低,钾肥用量更是不足,因而如何合理施用钾肥,提高钾肥对小麦产量与品质作用的研究已引起越来越多研究者的重视。本文从钾素对小麦产量及品质的构成因子的影响进行了阐述,对该领域的重点研究方向进行了展望。
In recent years, along with the increase of crop yield, the introduction and promotion of high - yield varieties, and using of more and more Nitrogen, phosphate fertilizer in the field, as well as reducing of the organic manure, soil potassium content reduced gradually. The amount of potash fertilizer used in production also insufficient. As a result, potassium fertilizer used reasonable and the research of increasing wheat yield&quality by potassium fertilizer has been attracted more and more attention to the scholars. This paper explained the effects of potassium on yield and quality of wheat, and discussed the future prospects of research directions in this field.
