近年来，在农业生产上存在土壤氮、磷肥施入量逐年增加，而对土壤钾肥的施入却很少，致使土壤氮、磷、钾比例失调，直接影响作物对肥料的吸收利用，进而影响到作物品质和产量的提高。为此，我们开展了小麦施用生物钾肥和硫酸钾的试验，取得了较好的增产效果。１钾肥的吸收... In recent years, there exists soil nitrogen and phosphorus fertilizer application in agricultural production increasing year by year, but little application of soil potassium fertilizer, resulting in imbalance of nitrogen, phosphorus and potassium in soil, which directly affects the absorption and utilization of fertilizers by crops and further influences To crop quality and yield improvement. To this end, we have carried out experiments on the application of bio-potash fertilizer and potassium sulphate to wheat and achieved good yield-increasing effect. 1 potassium absorption ...
