《农家顾问》今年第7期林南同志写的“作物巧施钾、增产潜力大”一文中提到:“硫酸钾适用于各种作物,氯化钾只适用于烟草、亚麻、马铃薯、茶树等作物”。我们认为此说法欠妥。 据我们所知,氯对烟叶的品质影响特别大:当叶片中含氯量达1％～2％时,就会呈青绿色,厚而发脆,边缘上卷,叶正面光滑而背面灰暗,这种症状先在下部叶开始;制成的烟含糖量低,吸时带怪杂味,燃烧性不好,容易黑灰熄火。 In his article “Farmers Consultant” written by Comrade Lin Nan in the 7th issue of this year, “Crop Potash Potassium with Potential for Increasing Production Potential” mentions: “Potassium sulphate is suitable for all kinds of crops. Potassium chloride is only suitable for tobacco, flax, potato, tea tree Other crops. ” We think this is a mistake. To the best of our knowledge, the effect of chlorine on the quality of tobacco leaves is particularly high: when the amount of chlorine in the leaves reaches 1% to 2%, it turns greenish, thick and brittle, with curled edges, smooth front leaves and dark backs, This symptom first begins in the lower part of the leaf; made of low sugar content, when the absorption zone with strange taste, burning is not good, easy black flame out.
