[目的]为寻找丽江金沙江河谷地区烟田适宜施氯量。[方法]试验设置6个施氯量处理(KCl 0、30、45、90、135、180 kg/hm2),比较各处理的烤烟生长、产质量表现。[结果]随施氯量增加,烟株的团棵期、现蕾期分别提前了2～3、3～5 d,终采期及大田期均延长了1～7d,烟株株高增加3.55～7.78 cm。增施氯使产量、产值、均价、上等烟比例、中上等烟比例分别提高了0.59%～10.70%、3.75%～10.92%、4.05%～8.56%、6.25%～28.13%、2.35%～5.88%。当施氯量为KCl 180 kg/hm2时虽产量最大,但较对照均价已下降0.82元/kg。施氯较为一致地提高了各部位烟叶的含氮量、含氯量,均降低了烟叶烟碱含量。施氯量效应表现为上部>中部>下部。施氯提高了上部烟叶的总糖含量,而降低了中部、下部烟叶的总糖含量。[结论]从烟叶的可用性和经济效益综合考虑,以KCl 135 kg/hm2为丽江砂质冲积型水稻土最佳施氯量。
[Objective] The research aimed to find suitable amount of chlorine for tobacco field in Jinsha River valley of Lijiang. [Method] Six treatments of applying chlorine (KCl 0, 30, 45, 90, 135, 180 kg / hm2) were set up to compare the growth, yield and quality of flue- [Result] With the increase of chlorine application, the stage of flowering and budding of tobacco plants were advanced 2 ~ 3, 5 ~ 5 d respectively, and the plant height of tobacco plants was increased by 1 ~ 7 d during the final harvesting period and the field. The plant height of tobacco increased 3.55 ~ 7.78 cm. The increase of the yield, the output value, the average price, the superior tobacco ratio and the middle and superior tobacco ratio increased by 0.59% -10.70%, 3.75% -10.92%, 4.05% -8.56%, 6.25% -28.13%, 2.35% ~ 5.88%. When the amount of chlorine application KCl 180 kg / hm2, although the largest production, but the average price has dropped 0.82 yuan / kg. The chlorine application increased the nitrogen content and the chlorine content of tobacco leaves more uniformly, and decreased the content of nicotine in tobacco leaves. The effect of applying chlorine is top> middle> bottom. Chlorination increased the total sugar content in the upper leaves and decreased the total sugar content in the middle and lower leaves. [Conclusion] Considering the availability and economic benefits of tobacco leaves, KCl 135 kg / hm2 was the best chlorine application rate for sandy alluvial paddy soil in Lijiang.
