If you want to use its seeds to plant, you must choose new seeds, the fruit should be full, if the color is red and yellow, so that it is fresh.

Second, heat preservation and budding

1. Soak the seed in 40 degrees hot water for 5 minutes, stir it constantly during this period, and then soak it in 20 degrees water for a day so that the seed can absorb enough water.

2. Wash the plate first, then cover it with a piece of wet cotton gauze, preferably white, put the soaked seeds on a plate, about 1000 grams of seeds on each plate. Then attach a piece of cotton gauze to the seed and cover it with a plate.

3. Control the temperature at about 20 degrees, wash the seed once a day, turn it over two or three times, spray water on the plate and moisturize it, so that the seed is in a suitable growth environment.

4. Wait until three or four days later, most of the seeds will grow buds of about 2 mm, and then they can be planted. Be careful that the buds of the seeds should not be too long, otherwise they are easy to be hurt when planting.

Third, sowing management

2. Then sprinkle the seeds evenly into the soil, with 30 inches between each space, and cover the seeds with soil two centimeters thick.

3. The seedlings will grow in a week or so, and the moisture should be controlled before the seedlings grow, otherwise the soil will harden and affect the seedlings.
