1、硝酸钾施用效果 硝酸钾是一种白色粉末状双元素肥料,含46％的氧化钾和13％的硝态氮,易溶于水,可全部被植物吸收,适合穴施、叶面喷施、随灌溉水施和配制成颗粒状复合肥施用。作物施用硝酸钾不但能显著增产,而且还能明显提高品质,提早成熟。如烟草施用硝酸钾,比不施增产10.9％～46.6％,比施硫酸钾增产3％～44.4％,上等烟叶大大增加,烤烟落黄更好,燃烧质量 1, Potassium nitrate application effect Potassium nitrate is a white powder two-element fertilizer containing 46% of potassium oxide and 13% of nitrate nitrogen, soluble in water, all absorbed by plants, suitable for point application, foliar spray Shi, with irrigation water and formulated into granular compound fertilizer. Crop application of potassium nitrate can not only significantly increase production, but also significantly improve the quality and early maturity. For example, the application of potassium nitrate in tobacco did not increase the yield by 10.9% -46.6% and the yield by 3% -44.4% than the potassium sulfate, the superior tobacco increased greatly, the yellowing of flue-cured tobacco was better and the burning quality
