After 55 days of transplanting, the differences of the 6 th leaf, the 10 th leaf and the 14 th leaf in each treatment are not large, and only the width of the 10 th leaf in 1 treatment is slightly smaller than that of other treatments. The length and the width of the 6 th leaf, the 10 th leaf and the 14 th leaf of the 3 th leaf are superior to those of other treatments 65 days after transplantation, and significant differences exist. The agronomic characters of all periods are combined, and the treatment 3 is superior to other treatments.
3.3 Comparison of economic traits for different treatments
As can be seen from the table 5, in the test comparison, the acre yield value and the average price of the treatment 3 are the highest, the first-class smoke proportion reaches 53.31 percent, and the comprehensive economic benefit is the best; the yield per mu of the treatment 2 is the second, the first-class smoke proportion reaches 50.22 percent, and the comprehensive economic benefit is inferior; the yield per mu of the treatment 1 is the lowest, the upper and middle smoke proportion is the lowest, and the comprehensive economic benefit is the worst.
4. Conclusion
Example 2 Total Water-soluble seed-raising Fertilizer N-P with growth promoting function 2 O 5 -K 2 O =28-0-5 is used for replacing the conventional tobacco seedling raising fertilizer, and the biological property and the agronomic property of the tobacco plant are good. CellExperiments show that the full-water-soluble seedling raising fertilizer with the growth promoting function in the embodiment 2 has the best tobacco plant growth vigor, field performance and field uniformity performance, the comprehensive economic benefit of flue-cured tobacco is obviously higher than that of other treatments, the economic benefit is the highest, and the middle-grade and top-grade tobacco proportion is the largest.

2.2 Test materials
The test varieties are: local main cultivar K326.
Fertilizer test: the organic fertilizer is provided by Kunming Yunyan Jinyuan biological organic fertilizer industry Co.Ltd;
example 3 Total Water-soluble Fertilizer for promoting growth (N-P) 2 O 5 -K 2 O=22-12-9）；
Compound fertilizer (N-P) special for tobacco 2 O 5 -K 2 O = 10-12-24), potassium phosphate nitrate fertilizer (N-P) 2 O 5 -K 2 O = 22-10-10), potassium sulfate (N-P) 2 O 5 -K 2 O = 0-0-52), provided by local tobacco companies.
2.3 design of the experiment
The test is researched by adopting a mode of field comparison, local conventional fertilization is used as comparison, and other production management measures and the like are executed according to local high-quality tobacco leaf production standards. The experimental fertilization treatment was as follows in table 6.
Note: 100 tobacco plants are planted in the test area and the control area respectively, and the total nitrogen amount of fertilization is kept consistent.
2.4 field management
Transplanting at 19 days 4 and 6 months in 2021, top dressing at 13 days 6 and 13 days in 2021, top dressing at 23 days 7 and 23 days in 2021, measuring the related agronomic characters of tobacco plants in the stem-growing period and the vigorous growing period, and randomly selecting 15 tobacco plants with moderate growth vigor for measurement in each cell.
3. Test results and analysis
From the results of table 7, it can be seen that: the influence difference of different fertilization treatments on various agronomic performance indexes of the tobacco plants in the bulk stage is not obvious, but the influence of the experimental treatment on the growth of the tobacco plants is better than that of the control treatment, which shows that the fully water-soluble seedling-improving fertilizer with the growth-promoting function is beneficial to promoting the growth of the tobacco plants.
From the results of table 8, it can be seen that: the plant height, stem circumference, leaf number, maximum leaf length and maximum leaf width of the tobacco plants in the bud period test are all superior to those of the control, and are respectively increased by 18.16%, 8.04%, 9.45%, 6.22% and 0.46% compared with the control.
4. Discussion and conclusions
From the result of the mass stage, the water-soluble seedling-extracting fertilizer with the growth-promoting function is more favorable for promoting the growth of tobacco plants compared with the phosphorus potassium nitrate fertilizer, and from the result of the bud stage, the mature stage of the tobacco leaves can be effectively advanced by applying the water-soluble seedling-extracting fertilizer with the growth-promoting function.
