The invention relates to the technical field of vegetable cultivation, and discloses a vegetable full-coverage ecological efficient cultivation technology which comprises the following steps: step 1, selecting and designing a functional composite mulching film which has the functions of temperature and humidity regulation, pest control, accurate nutrient release and soil protection, and the design of the mulching film comprises a multi-layer structure, each layer has different functions; and step 2, performing plastic film mulching: laying the functional composite plastic film on a vegetable planting area to cover the whole soil surface so as to form a full-coverage cultivation environment. Through optimization of a cultivation environment and accurate nutrient management, the growth efficiency and yield of crops are remarkably improved, a full-coverage cultivation technology and an intelligent fertilization system are combined, so that the crops can obtain appropriate moisture, illumination, nutrients and other elements in different growth stages, and thus healthy growth and disease resistance of the crops are enhanced; the overall quality and the market competitiveness of the vegetables are improved.

The application provides a control method of an air conditioning unit and the air conditioning unit. The air conditioning unit has multiple air outlets. A cabin is divided into multiple areas from top to bottom. Each area is connected with at least one air outlet. The control method comprises the following steps: when the temperature or humidity of the cabin does not meet the use requirement, the target temperature or target humidity of the middle area of the cabin is adjusted, and the target temperature or target humidity of other areas is set by compensation based on the target temperature or target humidity of the middle area; and the air valve opening degree of each area is controlled so that the temperature detected by each area is close to or equal to the target temperature. The cabin is divided into multiple areas, and air supply control is performed on each area, so that the temperature control in the cabin is more accurate. The temperature on the air outlet side of the condenser and the humidity on the air outlet side of the evaporator are corrected, and the temperature and humidity control efficiency of the unit is improved.
