1. Seed treatment

Before planting, the seeds should be treated simply. First, the impurities in the seeds or the seeds with shrunken shells should be cleaned out with a sieve, soaked in water at room temperature for about an hour, and then removed and drained, and the seeds can be sown.

2. Sowing seeds

Sprinkle the seeds of gray vegetables evenly on the finished land, and then gently rake the soil layer with a leaky rake so that the soil just buries the seeds. Then spray some water on it to keep the soil in a relatively moist environment.

3. Sowing method

If it is the way of broadcasting, the operation should be similar. When ploughing the land, the field is cultivated into a ditch with a row spacing of about 20 centimeters. The depth of each ditch is about five centimeters. Spread the treated seeds evenly and carefully in the ditch and cover them with a thin layer of soil about three centimeters thick to gently cover the seeds.

4. Daily management

Grey vegetables will grow seedlings after five or six days in the field. Because gray vegetables are inherently resistant, they are rarely likely to suffer from diseases. If there is enough bottom fertilizer when ploughing, it will be enough for its growth, and basically there is no need to top fertilizer again in the later stage. As long as frequent watering and weeding is enough, if gray vegetables have a high growth density, we have to pull out the weak and diseased seedlings from the field. This is called Miao, if there is not out of the seedling to make up for a strong seedling, this is called replenishing seedlings.

Grey vegetable was originally a kind of wild vegetable, but now it has been artificially planted because of its high nutritional value. Although the taste of artificial planting is not as delicious as game, there is no difference in general.
