The cultivating soil in the cultivating field loosens and breathes the soil in the tobacco field, and promotes the occurrence of adventitious roots and roots under the roots. The higher the soil, the more adventitious roots will occur, which will help the tobacco plants absorb water and attract fertilizers, promote the vigorous growth of tobacco plants in the long-term, and increase the quality and yield of tobacco leaves. There is a little grass in the tobacco field, which can improve the ecological environment. If there are too many grasses, it will compete with the leaves to compete with the water, affect the growth of tobacco, reduce the yield and quality.
Film covered with cultivated tobacco leaves, usually cultivating, earthing, weeding twice. For the first time, about 10 days after the planting of tobacco, shallow sips were made around the tobacco plants. The second time, after the removal of the film, deep cultivators were used to weed the soil. Take out the old leaves of the tobacco plant, and loosen the entire surface of the bed by 10-15 cm to make high earth. For tobacco leaves that are not covered with plastic film, three times of cultivating and weeding are generally performed. For the first time, about 10 days after planting tobacco, about 25 days for the second time, and about 35 days for the third time. The method is the same as that for mulching film.
