Therefore, if the temperature is kept high, the seedlings grow very fast, and the relatively thick and fleshy branches and leaves can be formed. At this time, the seedlings can be directly placed on the basin, and the pots with a diameter of about 10 cm are used, and 2 to 5 plants are planted per pot, and the survival rate is high and the growth is rapid.

When sowing, the human dung water is first applied in the ditch, and the seed ash can be evenly sprinkled.
Management: When the seed is raised, when the seedling height is one centimeter, pour a light human and animal manure to raise the seedling. When the seedling height is 3 to 4 cm, it is necessary to evenly seedling and replenish the seedlings. One seedling is kept every 3 to 4 cm, and the seedlings must be transferred with soil. After simmering the seedlings, weeding and weeding once, and topdressing in parallel.
