试验表明 ,在烟草每 666.7m2 施 K2 O1 4kg水平下 ,配施三分之一 KCl以代替部分 K2 SO4 ,不仅有助于缓解 K2 SO4 的紧缺 ,降低生产成本 ,还有改善烟株氯素营养 ,协调烟株内部的养分平衡 ,提高烟叶的外观质量和烟气质量的作用
Tests showed that applying K2 K1 4 kg at a rate of 666.7 m2 per tobacco with one-third KCl to replace part of K2 SO4 not only helped to ease the shortage of K2 SO4 and reduce the production cost, but also improved the chlorophyll nutrition of tobacco plants , Coordinating the nutrient balance inside the tobacco plant and improving the appearance quality and flue gas quality of the tobacco plant
