1. Sowing period In order to be listed in the autumn, some people will plant early, but premature sowing will cause bolting. Appropriate sowing period before and after the small heat (from the end of June to the middle of July), transplanted before the beginning of the autumn (early August), generally 40-50 days can be harvested, just in the autumn off season.
　　 2. Three methods of germination
　　 1 well hanging germination. First, the seeds are swollen in cold water, and then a layer of three inches of wet coarse river sand is placed in a small bamboo basket. The inflated seeds are laid on top, and the thick river sand and sand are covered with 1-2 cm. Cover the leaves with a leaf, or use gauze to wrap the seeds, place a damp brick in the middle of the seeds to adjust the moisture, and then hang it in a deep well to make it one foot above the water. Check it once a day until it is just "powder" (sprout is white), you can sow it. If there is no well, you can also use the urban sewer to promote germination.
　　 2 placed in cold and germination. Mix the inflated seeds with the moist river sand, place it in a cool and damp place (such as a wet water tank), and keep it moist. It usually starts to germinate in 3-4 days. The shortcoming is that the sprouting is slow and the growth is not neat.
　　 3 refrigerator germination or thermos with ice germination method. After soaking the seeds for 4-6 hours, pick them up, put them into small cloth bags, dry the seed skin in the small cloth bag, mix them loosely, and put them in the fresh-keeping layer of the refrigerator. You can also put 1-2 pieces of ice in the thermos bottle, then hang the seeds in the bottle, be careful not to touch the water below (the reduced version of the well germination), take out the seeds every 24 hours and rinse them with water. It can be germinated in about 48 hours.
After the seeds are germinated, they should be budded for 3 to 4 hours in the shade of the light. Pay attention to moisturizing when practicing buds.
