The main breeding method is sowing.

1. drill

According to the density, determine the sowing width and row spacing. Generally, the width of sowing ditch is 10 cm, the depth is 3 cm, and the row spacing is 25cm ~ 30cm. Seeds are evenly spread in the ditch, covered with 1cm ~ 2cm soil, watered, and then covered with plastic film or straw curtain.

2. On demand

Sowing is suitable for container seedling raising of Platycladus orientalis. The size of plastic containers commonly used in general production is 8 cm× 12 cm. Put the prepared nutrient soil into the nutrient cup, and the seedbed must be flat. Then the nutrition cups are placed vertically on the bed surface and close to each other in rows. The soil around the seedbed is firm and higher than the surface of the seedbed to prevent the container from tilting. Insert a wooden stick or screwdriver in the middle of the nutrition cup, aim the hole at the depth of about 1.5 cm to 2 cm, sow sterilized and germinated seeds in the hole, and sow 3 to 5 seeds in each hole. After sowing, evenly sprinkle fine sand with the thickness of 1 cm to 1.5 cm on the boundary surface, then water it once, and cover the grass curtain and grass curtain in windy or sunny days. When sowing in the nursery with mole cricket in the soil, poison particles should be scattered: stir-fry 15-22.5 kg of millet per hectare, mix with 7.5 kg of phorate, and spread in the furrow when sowing and fertilizing.
