The seed surface is covered with a layer of wax. If it is not cleaned, it will seriously affect the seed germination. Before sowing, it can be soaked in warm water for a period of time, or rubbed with alkali for a while, and then washed with water. Both methods are relatively simple and can effectively remove wax
Sowing in early spring, first evenly pour the soil through, then evenly spread the seeds on the sandy soil, covering with a thin layer of soil, at this time, maintain a certain humidity and temperature, can be wrapped with plastic film, which can not only heat preservation, but also moisture preservation, in the daytime, open the film for air permeability and watering, which is conducive to seed germination.
When the seedlings grow to 5cm-8cm high, they can be pulled out of the seedlings with weak rise, but also can increase the spacing of the seedlings. When the seedlings grow to about 20cm, they can be pulled out in the selection of the seedlings with weak growth. At this time, transplantation or colonization can also be carried out, but it is better to do it between April and may
About 10 days for a watering can be, the second selection of seedlings also need to carry out fertilization and weed control. During the growth period, it is not allowed to lack water. If it is found that the surface layer of the soil is dry, water it immediately. It is a water and fertilizer loving plant, especially in the growing period. However, it is not allowed to keep the soil in a moist or stagnant state for a long time.
