Abstract
[Objective] In order to select the best chloride application rate for flue-cured tobacco in valley of Jinshajiang river in Lijiang.[Method] Six kinds of chloride application rate with KCl 0(CK),30,45,90,135,180 kg/hm2 were set up,and the effects of chloride application rate on growth,yield and quality were tested.[Result] The results showed that,along with the increase of chloride application rate,the rosette stage,bud emergence stage were respectively advanced by 2-3,3-5 d,while last harvest date,growing period in field all delayed by 1-7 d.With chloride application increase,yield,output value,average price,ratio of superior tobacco leaf and ratio of superior-middle tobacco leaf respectively increase with 0.59%-10.70%,3.75%-10.92%,4.05%-8.56%,6.25%-28.13%,2.35%-5.88%.Although the amount of KCl 180 kg/hm2 have a maximum yield,but the average price reduced by 0.82 CNY/kg against CK.Chloride application generally increased the total nitrogen,chlorine of all leaves,while reduced the nicotine of all leaves.The chloride effect followed by upper leavescutter leaveslower leaves.In term of leaf position on the stem,chloride application improved the total sugar of upper leaves,while reduced the sugar of cutter leaves and lower leaves.[Conclusion] In the view of tobacco availability and economic benefit,the best chloride application rate was KCl 135 kg/hm2.
