摘要
通过田间试验,研究了忻州地区玉米施钾效应及适宜的施用量。结果表明,增施钾肥能明显促进玉米产量构成性状,玉米产量随着施钾量的增加而提高。每公顷施用K2O100kg,可基本维持土壤钾素肥力。
A Study on the effect and the reasonable amount of applied potassium fertilizer on corn was studied by field trial in Xinzhou. Results show that applied potassium fertilizer on corn improved the properties of yield structure, and corn yield increased with the increasing amount of applied potassium fertilizer. Applying 100kg K2O per hectare into soil will basically maintain soil potassium fertility.
