3. Sowing method: when sowing mulberry, trench was opened according to the spacing of 20 cm to 30 cm, ditch depth was 1 cm, seed consumption was 7.5 kg per square meter, covered with soil, and the seedling height was 3 cm to 4 cm after about 10 days.

The planting method of Mulberry

3. Planting method: when planting mulberry, it is required that the seedlings should be upright and root extended, the shallow planting should be firm, the fixed root water should be irrigated, and the plastic film should be covered with plastic film (3 feet wide and 2 feet wide). The mulberry buds were checked in time after germination, and those that did not survive were replanted in time.

4. Cut dry and sparse buds: after transplanting, cut off the stem of mulberry seedlings 5 inches from the ground. When the new buds grow to 4 inches, each plant will leave 2 to 3 strong branches with reasonable direction, and pick out the heart when the buds with only one bud grow to 4 inches.
