摘要:

为探索昭阳烟区不同连作年限烟地施肥对烤烟生长发育和产质量的影响,通过小面积同田对比优化施肥调控试验,分别对连作3、6、9年及轮作烟田,处理采取移栽时30%复合肥+氯化钾穴施,70%复合肥环施,团棵追施硝酸钾、硫酸钾、硫酸镁的施肥方式;同田对照采取移栽时复合肥环施+团棵追施硝酸钾、硫酸钾的施肥方式。结果表明:优化施肥调控处理可以改善连作烟地烟株农艺性状,增强烤烟抗逆性,降低病害发生,提高烤烟产量、产值、均价和上等烟比例,改善初烤烟叶化学成分协调性。

Abstract:

To explore the effects of fertilization on the growth, development, and yield and quality of flue-cured tobacco in different continuous cropping years of tobacco fields in Zhaoyang tobacco area, it was conducted by a small-scale field comparison experiment for optimization fertilization control. The continuous cropping fields of 3, 6, 9 years, and rotation were treated with 30% compound fertilizer + potassium chloride by hole application, 70% compound fertilizer by circular application, and topdressing with potassium nitrate, potassium sulfate and magnesium sulfate in resettling stage. The CK in same field were manured with compound fertilizer by circular + topdressing with potassium nitrate and potassium sulfate in resettling stage. The results showed that the regulation treatment of optimizing fertilization could improve the agronomic traits of tobacco plants in continuous cropping tobacco fields, enhance the resistance of flue-cured tobacco, reduce disease occurrence, increase yield, output value, average price, and proportion of top grade tobacco, and improve the coordination of chemical components in initial flue-cured tobacco leaves.

Key words: flue-cured tobacco, optimize fertilization, continuous cropping, agronomic characters, yield and quality
