Mature seeds are usually orange red around the White Dew solar term, and can be picked at this time. Select the fruit with good growth momentum and full and even fruit, and remove the shell after cutting with a knife. Prepare a basin of warm water, put the fruit in it and soak it for a period of time, wash the pulp with your hands, separate the seeds, pour out the water, remove the seeds and place them in a cool and ventilated place. Can't plant directly to put in the sand, storage, the next spring can plant
In a year except summer can be sown, but winter and autumn is the best, winter can be covered with insulation shed.
1. Choose a piece of fertile sandy land with smooth drainage, close to water source and sunny, preferably slightly acidic land. Generally, the advantage of seeding is that it can produce seedlings in a large area, so you can choose a large area of sandy land.
2. After selecting the land, prepare one month in advance, turn the land to a depth of 25 cm, remove impurities and level it, and add a proper amount of base fertilizer to supplement fertility. In deep turn when directly mixed into the soil.
Build high-tech and carry out seedling raising. Trim a high bed with a width of 1 m and a height of 25 cm, with an interval of 30 cm between each row, and adjust the bed surface to be flat.
3. Immerse the seeds in warm water of about 50 degrees, cool the water and then heat it. When it is cool, heat it for three times. Just knead the seeds and soften them.
4. Sow in a high bed. The distance between the seeds is 20cm or more. A planting pit can plant about 20 seeds, and the upper part is covered with 2cm soil. If possible, it can be used as a surface covering soil.
5. Cover the seeds with straw mat after planting. Wet the high bed with water until the soil is wet. After that, the water supply time will be determined according to the moisture level of the soil. It can sprout in about twenty days to a month. Then strengthen the management of water and fertility.
