1、 Seeding steps:

First, prepare the soil for sowing. This plant does not need too special soil, but it is best to prepare some sandy soil containing humus with good drainage. In addition to poor development in alkaline soil, this plant can grow healthily in both sandy soil and cohesive soil, especially in the sandy soil with slight acidity. If you want to prepare the soil yourself, you can mix the rotten leaf soil and the soil of the vegetable garden together in the same amount as the soil for sowing and cultivation

2 after the soil is ready, it should be disinfected to prevent diseases and insect pests from invading seeds or seedlings. The best way to disinfect is to put the soil in the pot and fry it hot to kill diseases and insect pests at high temperature

Then, in order to improve the success rate of seed germination, we can first give birth to buds and seedlings, soak the seeds with water up and down at about 25 ° C to 30 ° C for 3 to 10 hours, and then take them out when we see that the seeds swell due to full water absorption

4 some seeds are difficult to pick up by hand, so we can prepare toothpicks, wet one end of the toothpicks with water, stick up the seeds and put them on the prepared cultivation soil layer, subdivide them one by one, then cover them with a layer of soil one centimeter thick, and then put the sown flower pots in the water. The water immersion depth should reach about one-half or two-thirds of the height of the flower pots, so that the water should diffuse slowly

5 seeds with relatively large particles that can be picked up by hand can be directly placed on the soil layer, and the space between seeds should reach 3x3cm. After sowing, cover it with a layer of soil about 2 to 3 times the volume of the seed. After sowing, you can wet the soil layer with water, and then water it when you see that the soil on the basin is slightly dry

2、 Precautions:

The growth law of this plant is not much different from that of crops. It is sown in spring and harvested in autumn, so it can be sown in a mild spring, and the seeds can germinate only when the temperature is more than 20 degrees. Therefore, plastic sheds should be built for sowing in early spring to keep warm and sprout in about a week. If you sow in the north, you can delay the time
