Abstract
Field tests were conducted to research the influence of spraying different concentrations potassium sulfate on foliage on tobacco growth and quality.The results showed that under the specific soil ecological conditions of northern hills in Wenshan,Yunnan Province,the quality of tobacco leaves would be the best when potassium sulfate of 2% concentrations was applied.By spraying such potassium sulfate the maturity period would be brought forward for 2～3 d,tobacco would be 3.5 cm higher than the control after topping,the number of tobacco leaves would increase by 1.3 pieces,and the expanding of upper leaves would be accelerated; the occurrence of plant diseases would be reduced as well; not only the layered yellowing of tobacco would be promoted,but also the yellowing evenness and tobacco leaf thickness be improved; not only the yield would be increased,which would be increased by 168 kg·hm-2than the control,but also oil content and color of tobacco be improved; chemical component of tobacco would be more balanced as well so as to reduce superfluous aroma and increase tobacco aroma and also the usability of tobacco leaves.

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.
Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
