摘要
为生产上贪青徒长烟株的合理施肥提供科学依据,采用田间试验方法,研究打顶后3d叶面喷施磷酸二氢钾500g/667m2、磷酸二氢钾1000g/667m2、新品钾肥(添加液体增效剂)500g/667m2、新品钾肥(添加固体增效剂)500g/667m2和等量清水(CK)对贪青徒长烟株产质量的影响。结果表明:喷施钾肥各处理的产量、产值、中上等烟比例和上等烟比例均高于CK,以喷施新品钾肥(添加固体增效剂)的效果最好。喷施新品钾肥(添加固体增效剂)中上等烟比例和上等烟比例较CK分别提高11.2%和11.1%;产值较CK提高499.6元/667m2;收入较CK增加479.6元/667m2,增幅9.82%;可有效促进贪青徒长烟株落黄,改善烟叶内在化学成分的协调性和感官评吸品质;C3F和B2F烟叶的钾离子含量分别为2.97%和2.46%,与CK差异极显著。施用新品钾肥(添加固体增效剂)可有效促进贪青徒长烟株成熟落黄,提高烟叶钾离子含量及产质量。
To provide a scientific basis for the rational fertilization of the over-green and spindling tobacco plants,according to the field experiment,test CK(spray water),T1(potassium dihydrogen phosphate 500 g/667m^2),T2(potassium dihydrogen phosphate 1000 g/667m^2),T3(new potash add liquid synergist 500 g/667m^2),T4(new potash fertilizer add solid synergist 500 g/667m^2)5 treatments were designed for investigating the effect of spraying potassium fertilizer on the yield and quality of the over-green and spindling tobacco plants with spraying 3 days after topping.Results:The yield,output value,proportion of medium and high quality tobacco and proportion of high quality tobacco in each treatment of potash fertilizer spraying were all higher than CK,and the effect of new potassium fertilizer spraying(adding solid synergistic agent)was the best.Compared with CK,the proportion of medium and high quality tobacco and the proportion of high quality tobacco in new potassium fertilizer(adding solid synergistic agent)were increased by 11.2%and 11.1%respectively.The output value is 499.6 yuan/667m^2 higher than CK;Compared with CK,the income increased by 479.6 yuan/667m^2,an increase of 9.82%.It could effectively promote the greediness of tobacco,improve the coordination of chemical components in tobacco leaves and improve the quality of sensory evaluation.The potassium ion contents of C3F and B2F tobacco leaves were 2.97%and 2.46%,respectively,which were significantly different from CK.Application of new potassium fertilizer(adding solid synergistic agent)could effectively promote the maturation and yellowing of over-green and spindling tobacco,and improve the potassium ion content and yield and quality of tobacco leaves.
