Embodiment 1
[0023] This example is a specific example of preparing compound preparations 1-3 according to the technical solution provided by the present invention.
[0024] Weigh 3gGA3, 5g indole acetic acid, 250g potassium dihydrogen phosphate and 3g Tween 20 and mix to obtain compound preparation 1.
[0025] Weigh 5 g of GA3, 3 g of indole acetic acid, 200 g of potassium dihydrogen phosphate and 2 g of Tween 20 and mix to obtain compound preparation 2.
[0026] Weigh 4gGA3, 4g indole acetic acid, 150g potassium dihydrogen phosphate and 4g Tween 20 and mix to obtain compound preparation 3.
Embodiment 2
[0028] This example is a specific example of spraying the composite preparations 1-3 prepared in Example 1 on a field for planting tobacco leaves.
[0029] 31.6g of compound preparation 1 was dissolved in 15kg of water, and mixed to obtain mixed solution 1.
[0030] 31.6g of compound preparation 2 was dissolved in 17kg of water, and mixed to obtain mixed solution 2.
[0031] 31.6g of compound preparation 3 was dissolved in 20kg of water, and mixed to obtain mixed solution 3.
[0032] 31.6g of the plant production regulator was dissolved in 15kg of water, and mixed to obtain a control solution. In this example, the plant growth regulator is a commercially available conventional growth regulator.
[0033] In this example, the experimental material is Yunyan 99. Randomly select four pieces of Yunyan 99 with the same area to be planted in fields, namely: field 1, field 2, field 3 and field 4, field 1 is sprayed with mixed solution 1, field 2 is sprayed with mixed solution 2, an...

Abstract
The invention belongs to the technical field of tobacco planting and particularly relates to a compound preparation and a spraying method thereof. The compound preparation comprises gibberellin, indoleacetic acid, potash fertilizer and non-ionic surfactant. The invention further provides the spraying method of the compound preparation. The spraying method includes the steps that the compound preparation is dissolved in water, and a mixed solution is obtained through mixing; the mixed solution is sprayed on surfaces of leaves on the upper portions of tobacco plants. According to actual spraying and measurement, the compound preparation and the spraying method can effectively increase the total sugar content, the reducing sugar content, the potassium content and the nicotine content in tobacco leaves, meanwhile, the starch content is reduced, and the ratio of sugar to nicotine and the ratio of nitrogen to nicotine are increased. Besides, the compound preparation and the spraying method can effectively increase the flue-cured tobacco yield, the production value and the first-class tobacco proportion, and economic benefits are remarkably improved. The technical scheme is simple, convenient to use and suitable for large-scale popularization.
Description
technical field [0001] The invention belongs to the technical field of tobacco planting, and in particular relates to a composite preparation and a spraying method thereof. Background technique [0002] Flue-cured tobacco (Nicotianatabacum L.) is an economic crop for the purpose of harvesting tobacco leaves. Improving the quality of tobacco leaves has an important role in promoting the economic benefits of flue-cured tobacco. Southern Shaanxi is the main production base of flue-cured tobacco in Shaanxi Province. It has a humid subtropical climate with abundant precipitation and sufficient sunlight. Shangluo City is one of its main tobacco planting areas. At present, the tobacco planting area in Shangluo City is about 100,000 mu, and the output is between 250,000 and 300,000 dan. The aroma of the flue-cured tobacco in this tobacco area is relatively transparent, with a strong sense of aroma and a good sense of sweetness. [0003] Potassium is an important quality element of ...
