叶面喷施氯化镁对烤烟产质量的影响

Effects of Foliar Spraying Magnesium Chloride on Yield and Quality of Flue-cured Tobacco

为探明叶面喷施不同量氯化镁对烤烟产质量的影响,以“K326”烤烟品种为试验材料,采用大田试验方法,设置不同时期叶面喷施不同次数氯化镁(LYL1、LYL2、LYL3)处理和空白对照,分析各处理对烤烟烟叶产量和化学成分的影响。结果表明,叶面喷施氯肥处理的烟叶产量均高于对照处理,提高了6.67%~15.29%,其中LYL1处理烤烟产量最高且与对照处理相比差异显著;叶面喷施氯肥处理烟叶产值比对照处理提高11.90%~17.55%,其中LYL1处理烟叶产值最高,且LYL1、LYL3处理烟叶产值与对照相比差异显著。叶面喷施氯肥可显著改善烤烟烟叶化学成分的协调性,提高烟叶内在品质。综上所述,在富川县当地土壤和环境条件下,叶面喷施氯肥处理可显著提高烤烟烟叶的产量、产值和品质,对当地高产优质烟叶栽培具有重要参考意义。

In order to investigate the effect of foliar spraying with different amounts of magnesium chloride on the yield and quality of flue-cured tobacco,the"K326"flue-cured tobacco variety was used as the experimental material.Field experiments were conducted to set up treatments of foliar spraying with different times of magnesium chloride(LYL1,LYL2,LYL3)at different stages and blank controls.The effects of each treatment on the yield and chemical composition of flue-cured tobacco leaves were analyzed.The results showed that the yield of tobacco leaves treated with foliar spraying of chlorine fertilizer was higher than that of the control treatment,with an increase of 6.67%-15.29%.Among them,LYL1 treatment had the highest yield of flue-cured tobacco and had a significant difference compared to the control treatment.The output value of tobacco treated with foliar spraying of chlorine fertilizer increased by 11.90%-17.55%compared to the control treatment,with LYL1 treatment had the highest output value,and LYL1 and LYL3 treatment had significant differences in output value compared to the control.Spraying chlorine fertilizer on the leaves could significantly improve the coordination of chemical components in flue-cured tobacco leaves and enhance their internal quality.In summary,under local soil and environmental conditions in Fuchuan County,foliar spraying with chlorine fertilizer could significantly improve the yield,output value,and quality of flue-cured tobacco leaves,which has important reference significance for local high-yield and high-quality tobacco cultivation.
