Description

Technical Field

[0001] The utility model relates to the technical field related to tobacco transplanting, in particular to a tobacco transplanting device. Background Art

[0002] Tobacco cultivation has a long history. Planting tobacco can drive regional economic development. Tobacco is an economic crop that can create a lot of economic value for growers. In some areas of many provinces in my country, tobacco is the main source of income. Transplanting tobacco seedlings can shorten the growth cycle, reduce the seedling shortage rate, increase the seedling success rate, and reduce pests and diseases.

[0003] Before transplanting tobacco, the plastic film and other pollutants in the tobacco field should be cleaned up in time. During the transplanting process, smoking and any other behavior that damages or pollutes the tobacco seedlings and tobacco fields is prohibited. After the cleaning is completed, the land needs to be plowed, leveled, ridged and built. Ridges should be made in time on sunny days when the soil is loose and fragmented. The ridge quality should be high and full, with a flat surface and fine soil. The ridge height should not be less than 30cm. The ridge direction should be in the same direction as the local valley wind flow, which will accelerate the air circulation in the salt field, help regulate the field microclimate, and thus increase the land The surface heating area increases the ground temperature. After ridge formation, the tobacco rows are arched, which expands the light-receiving area of ​​the soil, which is beneficial to increasing the ground temperature. At the same time, it is beneficial to the decomposition and transformation of nutrients and the early growth of tobacco plants. The soil layer is loosened and the vertical depth and length of the root system are expanded. Finally, a film is needed on the ridge to keep it moist. At present, tobacco transplanting is mainly based on artificial cultivation technology. In the process of transplanting seedlings, most of the manual methods are used to dig holes and sow seeds. The staff are required to intermittently dig holes on the ridge and transplant the tobacco seedlings one by one. The operation is time-consuming and labor-intensive, and the labor intensity is relatively high. Utility Model Content
