Application of Regulators to Increase Tobacco Yield and Improve Quality
Brassinolide
The quality of the middle and upper leaves of tobacco is the best, and the quality of the lower leaves is the worst. Tobacco treated with brassinolide can promote the growth and development of tobacco plants, expand the leaf area per plant; promote photosynthesis and material transportation and distribution, improve the chemical composition of tobacco leaves, and the nicotine content can be increased by 39.4% to 76.7%. Proportion. After the tobacco cluster stage, when there is a certain amount of light after the high temperature in the afternoon, using 0.01-0.04mg/L brassinolide, the effect of spraying the back of the leaves is better. The lower leaves can be sprayed first and then sprayed upwards in turn with the harvest. When spraying, if 0.1% zinc sulfate is added, the effect is better.
DCPTA
After planting, in the cluster stage and growth stage, spray 20-30mg/L DCPTA liquid evenly on the whole plant to promote
Make seedlings strong, green leaves prevent premature aging.
Sodium Nitrophenolate
Use 3-6mg/L sodium nitrophenolate solution to spray twice on the leaves of the whole plant at an interval of 10d at the cluster stage to increase yield
Significantly, the proportion of high-quality tobacco can be increased, and the output value can be greatly increased.
Triacontanol
From the clustering stage to the peak growth stage, spray 0.4-0.6 mg/L triacontanol on the foliage for a total of 2-
3 times, can increase the output.
Zeatin
10d after transplanting, spray 3 times with 0.0016-0.0025mg/L liquid medicine with an interval of 7d, which can promote leaf growth.
Green content, promote leaf weight, increase yield significantly, and reduce the occurrence of mosaic disease. 8 Toguasis Books
Gibberellic acid
After cultivating soil at the large seedling stage of tobacco, spray the leaves with 15mg/L gibberellic acid solution, and then spray once every 5 days, which can promote carbon and nitrogen metabolism, increase the content of nicotine and potassium, reduce the content of nitrogen, and improve the quality of tobacco leaves , the proportion of middle and high-quality tobacco leaves increased by 9%, which increased the area of tobacco leaves, enhanced the photosynthetic intensity of leaves, significantly increased the weight of single leaf and leaf quality, and increased the yield of tobacco leaves by 20%.
Cytokinin and indoleacetic acid
Spraying 10 mg/L cytokinin and 30 mg/L indole acetic acid 5 days after topping can significantly increase the stem diameter, leaf length and leaf width in the upper leaves of tobacco plants, effectively reduce the nicotine content in the upper leaves, and increase the total sugar and total potassium content , can effectively adjust the ratio of sugar to alkali, and has a good effect on improving the quality of upper leaves.
