(early 4 months 2023)

(2) Changing the pot of tobacco seedlings: when 4 leaves grow out, the tobacco seedlings are transplanted to a new seedling pot and continue to grow.

(3) Preparing a moss biological blanket:

the artificial planting of the east Asian sphagnum is selected, and the east Asian sphagnum is a high-quality seed source with thick stem and leaf bodies, excellent growth state, no disease and insect damage, no large-area withered and yellow, no other sphagnum seed mixing, no soil, no dry branch, leaf and weed mixing.

On the spun-laced non-woven fabric, the moss matrix glue is used for uniformly discharging the east Asia moss, the moss is uniformly and fully paved, no defect exists, and the moss color is normal without withered and yellow deterioration. The matrigel is coated uniformly, no leakage and no overflow, and as shown in figure 1, moss is covered on the spun-laced non-woven fabric by more than 98%.

(4) Land arrangement and ridging: the soil is selected from benign soil with good environment and no pollution source nearby, and is prepared in the modes of shallow tillage stubble cleaning, tillage, harrowing, land leveling, compacting, land leveling and ridging, wherein the height of the ridge is about 40cm, and the width of the ridge base is about 20cm.

(5) Spreading the moss biological blanket with the thickness of 2m multiplied by 60cm on ridges, covering, and compacting with soil at the base.

(6) Circular planting holes with the diameter of about 15cm and the interval of about 60cm are cut out on the covered moss biological blanket by scissors.

(7) Tobacco seedlings grown for 50 days are transplanted into field planting holes covered by biological blanket for subsequent growth (2023, 5 months old).

(8) Soil of tobacco covered by biological blanket is sampled when the tobacco grows for about 80 days, the content of quick-acting phosphorus and quick-acting potassium in the soil is measured, the sampling point is 5cm away from the root of the tobacco and 15cm deep (2023, 6 months), and the data are shown in figure 2. Soil temperature was measured every 4 hours from 21 in 2023, 5 months, 21 to 2023, 5 months, 23, and the data are shown in FIG. 3. The effect of the sphagnum biological blanket interplanting tobacco is shown in figure 4.
