Description
Technical Field
The invention belongs to the field of tobacco planting equipment, and particularly relates to a multifunctional tobacco ridge heat preservation device combined with drip irrigation.
Background
The mulching film mainly utilizes the plastic film with very thin thickness to cover the soil for crop growth, so that the soil can be subjected to heat preservation and fertilizer preservation, and in the prior art, the mulching film mulching cultivation belongs to a very mature crop cultivation technology, but with the large-scale use of the mulching film and the lower recovery rate of the mulching film, the mulching film pollution of a field is gradually aggravated. Especially, the ultra-thin mulching film is used, and the physical strength is insufficient due to the fact that the thickness of the ultra-thin mulching film is too small, so that phenomena such as cracking, ageing, weathering and the like are easy to occur in the growth process of crops, and the ultra-thin mulching film cannot be effectively recycled.
In the prior art, some technical concepts of hard mulching films are proposed, for example, patent documents with publication number of CN205546759U, CN207978541U, CN208783373U and the like, although a covering structure with large thickness and high hardness is provided to realize the repeated utilization of the structure so as to prevent pollution caused by weathering and crushing, the technical scheme is more similar to the miniaturization of a greenhouse structure, the practicality of covering soil as a mulching film is poor, meanwhile, the mulching film also needs to perform hole digging and seedling digging operations, such as strawberries, tobacco plants and the like, and for crops with long growth time and large volume of tobacco, the mulching film needs to be separated from ridge soil in the middle growth stage of the tobacco plants, namely, the mulching film is not needed, and the hard mulching film in the prior art cannot realize the functions.
Meanwhile, when the tobacco plants are transplanted in 4-5 months of the film covering period, the day and night temperature difference of the field is larger, the subfilm soil at the root of the tobacco plants is subjected to stronger illumination in daytime and is heated up rapidly, the temperature is up to more than 50 ℃, the mulching film needs to be torn in time for ventilation and heat dissipation so as to prevent the root of the tobacco plants from being injured, but the heat preservation effect of the mulching film is damaged directly, and tobacco farmers also need to realign and pave the torn mulching film in the evening and cover the torn mulching film with the soil so as to keep the heat preservation effect of the mulching film as much as possible to resist the low temperature at night. The whole operation is labor-consuming and time-consuming, and influences the growth of tobacco plants, so that the growth speed of the tobacco plants is easily reduced, and the development quality of leaves is easily reduced.
