摘要
本研究以烟草品种K326为试验材料,采取随机区组设计试验,设常规施肥(对照)、紫色土复合土壤调理剂、红房子土壤调理剂3个处理,研究施用不同品种土壤调理剂对植烟土壤养分状况、烟草生长、产量的变化,增施土壤调理剂对烟草的产量、品质、环境的影响,为协调烟草高产高效和改良土壤提供理论技术指导。研究结果表明:紫色土复合土壤调理剂提高了土壤pH和土壤缓效钾含量,降低了大田青枯病发病率,促进了烟株健康生长,烟叶的产量、产值和烟叶质量都得到了提高。
In this study, tobacco variety K326 was used as the experimental material for the randomized block design experiment was carried out. Three treatments are set in the test: Conventional fertilization (T1), purple soil compound soil conditioner(T2) and red house soil conditioner (T3) were used to study the changes of soil nutrients, tobacco growth and yield, and the effects of increasing soil conditioner on tobacco yield, quality and environment. To provide theoretical and technical guidance for the coordination of high yield and high efficiency of tobacco and the soil improvement, the results showed that purple soil complex soil conditioner increased soil pH and slow-release potassium content, reduced the incidence of bacterial wilt in the field, promoted the healthy growth of tobacco plants, and improved the yield, output value and quality of tobacco leaves.
