摘要
采用裂区试验,以土壤改良剂施用为主因子,烤烟留叶数处理为副因子,以不施用土壤改良剂为对照,分别设常规施肥配施土壤改良剂、常规施肥减氮20%+土壤改良剂2个处理;以22片留叶数为对照,设19片留叶数为1个处理,探究配施土壤改良剂及留叶数处理对烤烟NC297生长发育和经济效益的影响。结果表明:不同土壤改良剂及留叶数处理对烤烟NC297的农艺性状、养分含量及经济性状的影响存在显著或极显著差异,其中常规施肥减氮20%+土壤改良剂和19片留叶数处理的烤烟产值、中上等烟比例相对较高,明显优于其他处理,有助于提高烤烟的经济效益。试验结果可为烤烟NC297的土壤改良剂配施及留叶数处理在楚雄吕合产区的应用提供参考依据。
The split zone test was adopted.The application of soil amendments was the main factor,and leaf retention treatment of Flue-cured Tobacco was the secondary factor.The local conventional fertilization without applying soil amendments was used as the control,and two treatments were set:conventional fertilization with soil amendments and nitrogen reduction of 20%with soil amendments.Using 22 leaves as a control and 19 leaves as one treatment,the effects of soil amendments and leaf retention on the growth and development of flue-cured tobacco NC297 were studied.The results showed that different combinations of soil amendments and leaf retention had significant or very significant effects on the agronomic traits,nutrient content,and economic traits of tobacco NC297.Among them,the nitrogen reduction of 20%+soil amendments and 19 leave retention treatments had the highest output value and proportion of medium to high quality tobacco,which was better than other treatments and helped to improve economic benefits.This result can provide a theoretical basis for the application of soil amendments and leaf retention treatment of flue-cured tobacco NC297 in Chuxiong Lyuhe production area.
