The planting method of tobacco

At present, tobacco is grown in many places in our country, although many people know that attraction is harmful to health, but the demand for cigarettes in the market is still very high. And tobacco cultivation in many places is still a national poverty alleviation project. So how to grow tobacco? Now let's learn how to grow it.

1. Planting environment

The environmental requirements of tobacco planting are still relatively high. It is a kind of warm plant, the average temperature of the general planting ground is between 10 and 38 degrees, and the most suitable temperature for tobacco growth is between 25 and 30 degrees. On the other hand, tobacco needs the most water in the middle of its growth, and the humidity in the field is best kept at about 70% to 80%. In addition, its growth needs enough light, and it is best to keep it at about eight to ten hours a day. Red loam is the best planting land for tobacco, followed by red loess, sandy soil and so on, among which black loam is generally not suitable for growing tobacco.

2. Seedling management

Before sowing, you need to put the tobacco seeds in the sun for two or three days, which can improve the germination rate of the seeds. Tobacco seedlings generally use double-layer film paper tube seedling technology, so that the tobacco seedlings are stronger. Secondly, the nutrient soil for raising seedlings also needs to be allocated, generally, 60% of the large fill and 40% of livestock manure are mixed evenly, and an appropriate amount of compound fertilizer is needed. Sowing is usually around the middle of February every year, and heat preservation is done at the same time.

3. Transplanting seedlings

It is best to plant tobacco at the right time and early, so that the planted tobacco is of better quality. When transplanting, you can generally plant about 1000 to 1300 plants per mu, and this density of tobacco can carry out full photosynthesis. At the same time, it is convenient to operate in the field. Plastic film should be covered when planting tobacco, which can not only play the role of heat preservation and moisturization, but also improve the resistance of tobacco to drought and waterlogging. When the temperature rises, the plastic film needs to be cut open to prevent water loss.

4. Field management

There is a certain contradiction between the yield and quality of tobacco planting. Generally speaking, the higher the output, the worst the quality, but the low output does not mean high quality, so the management of the field is very important. The planting of tobacco is mainly based on base fertilizer, which must be fully applied, using the method of balanced fertilization. In the early stage, it is mainly based on nitrogen fertilizer, combined with phosphate fertilizer and potassium fertilizer. If there is a lack of fertilizer in the middle and later stages of tobacco growth, then foliar spraying is needed for fertilization. At the same time, we also need to pay attention to drainage and waterlogging prevention, mid-ploughing, weeding and loosening soil to enhance the permeability of the field. Finally, it is necessary to hit the top in time, which is the main way to improve the quality of tobacco.

5. Harvesting and processing

The harvest and processing of tobacco is the key to the production of high quality tobacco. The harvest of tobacco leaves is generally when the tobacco leaves are mature, generally showing that the leaves are green and turn yellowish green, and can not be harvested too early or too late, otherwise the quality of flue-cured tobacco will not be greatly reduced.

The above is what the editor has sorted out for you, about the methods of growing tobacco. I believe you also have a certain understanding of tobacco cultivation. At present, tobacco cultivation is also relatively profitable, but the workload is also relatively large, and the key is that the planting technology and flue-cured tobacco technology is also very critical. If you encounter any problems in the later period, you can leave a message for the editor.
