What should we pay attention to when planting tobacco with plastic film mulching? Ridging and fertilizing the land. In the areas where tobacco-rice rotation is to be finished in mid-March, we must seize the favorable weather and set up ridges and fertilizers before February. After ridging, apply herbicide, and then apply hole fertilizer to break the topsoil in order to cover the film. Cover the film. The surface of the soil must be moist, and the film can only be covered when the water holding capacity reaches 80%. Otherwise, the film cannot be covered. Cover the film should be close to the side of the box, taut and straightened, pressed around with soil, so that the wind can not move. Grow tobacco. Under the film cultivation, if you cover the film before planting tobacco, open one side of the film when planting tobacco, after planting the seedlings, pour and press the water, and then cover the film. There is no film before planting tobacco, and cover the film immediately after planting tobacco. If the cultivation is on the film, make a small hole in the hole on the side of the box, plant the tobacco seedlings into the hole, pour water and fertilizer, and then press the mouth of the film with soil. Check the seedlings and replenish the disease. Within 7 days after planting, check the tobacco field and find dead seedlings in time. Open the hole to lift the seedling. For tobacco seedlings cultivated under plastic film, when the leaves grow to withstand the plastic film, the holes must be opened in time, or when the temperature in the film is more than 30 ℃, the leaves of tobacco seedlings should be exposed on the film surface and the tie mouth should be pressed with soil. Otherwise, the tobacco seedlings will be burned out. Uncover the film. When tobacco seedlings are covered with film for about 40 days, or grow to the rosette stage, the film must be uncovered in time. The residual film must be cleaned and dealt with centrally, and should not be thrown everywhere. Click to get more tobacco planting techniques click to get more flower planting techniques
