How to grow flue-cured tobacco to achieve high yield?

Flue-cured tobacco is a type of tobacco that has a unique aroma and taste after being processed through a special baking process. It is an important raw material in the tobacco industry and has high economic value. So how can we grow flue-cured tobacco to achieve high yield? Let’s learn more about it below.

1. Variety selection

Select flue-cured tobacco varieties with strong adaptability, good disease resistance, high yield and excellent quality. Such as K326, Yunyan 87, etc.

2. Site selection and land preparation

Flue-cured tobacco is suitable for planting in soil with deep soil layer, good structure and strong water and fertilizer retention capacity. The pH value should be between 6.0-7.5. Before sowing, deep plowing, harrowing, and ridge making should be carried out, and the ridge surface should be made flat when making ridges. Additionally, soil fertility can be improved by adding compost or organic fertilizers .

3. Sowing and seedling raising

Select flue-cured tobacco seeds with full grains, good quality and good appearance for soaking and seedling promotion. Soak the seeds in a disinfectant solution at about 20 degrees for 10-15 minutes, then take them out, wash them with clean water and put them in a wet gauze bag for germination. Spray water on the wet gauze bag every morning and evening. When more than half of the seeds begin to show white tips, they can be planted in the seedling bed.

4. Transplant at the right time

When transplanting, care should be taken to keep the root system of the tobacco seedlings intact and to plant them at a reasonable density to ensure transplanting quality. The wet planting and film covering method is adopted, and the planting density of tobacco seedlings is controlled at 15,000-16,500 plants/hectare, the row spacing is controlled at 110-120 cm, and the plant spacing is controlled at 50-60 cm.

5. Water management

Irrigate in time according to soil moisture and the needs of tobacco growth and development. Generally, the water requirement is less in the seedling stage, more in the growth stage, and the water requirement should be appropriately controlled in the mature stage.

6. Reasonable fertilization

Fertilization of flue-cured tobacco is generally divided into two stages: base fertilizer and topdressing. Base fertilizer is usually applied before transplanting, mainly organic fertilizer. Top dressing is usually applied in the middle and late stages of flue-cured tobacco growth, mainly nitrogen fertilizer.

7. Pest and disease control

Regularly check the growth of flue-cured tobacco in the field, and detect and deal with diseases and pests in a timely manner. Among them, diseases such as angular leaf spot and wildfire can be controlled by spraying agricultural streptomycin in mid-June each year; for insect pests, solar-powered vibration-type insect-killing lamps can be installed to control cutworms, or yellow sticky insect boards can be used to control aphids.

In general, to achieve high yields of flue-cured tobacco, it is necessary to carry out refined management of every link from variety selection to pest and disease control. Finally, by doing the correct harvesting work, the goal of high-quality and high-yield flue-cured tobacco can be achieved.
