Description

Agricultural plastic film laying device convenient to adjust Technical Field The invention relates to the technical field of agricultural tools, in particular to an agricultural mulching film laying device convenient to adjust. Background The plastic film mulching is a cultivation technology widely applied to modern agriculture, and has multiple functions of heating, water retention, fertilizer retention, soil physicochemical property improvement, soil fertility improvement, weed growth inhibition, disease alleviation and the like. Under the condition of continuous rainfall, the technology can also effectively reduce the field humidity, thereby creating a more suitable growing environment for crops, promoting the plants to grow robustly, and leading the plants to bloom and fruit in advance, thereby not only increasing the crop yield, but also obviously reducing the labor cost. At present, most of mulching film laying is finished manually, in the operation process, because the farmland width is usually larger, operators need to fix and lay one side of the mulching film first and then to and fro to finish the other side, the process is complex, the efficiency is low, and the labor intensity and the work load are greatly increased. In addition, because of the practical planting requirement, the mulch film is often required to be punched after being paved, so that crops such as vegetables and the like can grow smoothly in a seedling emergence mode, and the normal development of the crops is prevented from being influenced due to the blocking of the mulch film. However, it is common practice to uniformly punch holes after the whole mulching film is laid, at this time, the film body is completely unfolded and fixed on the ground, the operation space is limited, the punching operation is very inconvenient, and the integrity of the mulching film is easily damaged. If the holes are punched in advance before the holes are paved, the size of the hole diameter, the hole distance and the hole position distribution are difficult to accurately control, the actual planting position is easily mismatched with the punching position, and the growth uniformity of crops and the land utilization efficiency are affected.
