Full-growth-period film mulching planting method for low-latitude high-altitude tobacco-growing area

The invention discloses a low-latitude high-altitude tobacco-growing area whole-growth-period film-mulching planting method which comprises the following steps: 1) performing soil preparation on a tobacco-growing field in early April, applying base fertilizer in furrows to form ridges, and covering the ridges with a mulching film; 2, well cellar holes are dug in the ridge bodies in mid-to-late April, and tobacco seedlings are transplanted into the well cellar holes; and 3) in the beginning of May, forming a water-permeable hole in the middle position of two adjacent tobacco plants on the mulching film, covering a layer of fine soil on the water-permeable hole, and performing conventional field treatment on the rest of the tobacco plants. According to the method, the water permeable holes are formed in the mulching film and the middle position of the two tobacco plants and covered with the soil, so that the temperature of the ridge body is guaranteed, the soil moisture can be increased, and the growth of the t
