For example, for planting aster in a large area, the deep ploughing must reach 20 ~ 23 cm, and it needs to be plowed and raked for many times to make the soil particles uniform and fine, and the border surface is flat.
2. Reproduction: Aster reproduces with fine roots near the ground, with a root length of about 35cm.
After planting in Tomb-Sweeping Day in the spring from the vernal equinox, dig out the seed roots with a shovel, cut them into 3-6 cm lengths with scissors, then furrow them, and put the cut seed roots (5-8 roots) into the ditch with a depth of 7-10 cm and a square cluster of 3-6 cm; Rows 1 and the second row 17cm also have roots planted at a spacing of 34cm, forming a triangle. In a small piece of land, dig ditches with picks, plant seed roots, then cover the soil, level the ground, make a border, water it, and germinate in about 20 days. Weeds should be removed frequently after emergence, watered for the second time, and watered for the third time after the seedlings grow into plants.
