1、 Seed taking

Mature seeds are generally orange red before and after the Bailu solar term, and can be picked at this time. When taking seeds, select the fruit with good growth momentum and full and uniform fruit, and remove the shell after cutting it with a knife. Prepare a basin of warm water, put the fruit in and soak it for a period of time, scrub the pulp by hand, separate the seeds, pour out the water, take out the seeds and place them in a cool and ventilated place. It cannot be planted directly. It should be stored in sand and sown in the next spring

2、 Sowing time

In a year, seeds can be sown except in summer, but winter and autumn are the best. Heat preservation shed can be covered in winter

3、 Sowing method

1. Choose a sandy land with smooth drainage, close to water source and sunny and fertile, preferably slightly acidic land. The advantage of planting seedlings in general is that they can emerge in a large area, so you can choose a large sandy land

2. After the land is selected, it shall be prepared one month in advance. The land shall be turned over at a depth of 25 cm, the impurities shall be removed and leveled, and an appropriate amount of base fertilizer shall be added to supplement the fertility. When turning deeply, it can be mixed directly into the soil

Build high-tech plants for seedling raising. Trim a high bed with a width of 1m and a height of 25cm, with an interval of 30cm between each row, and adjust the bed surface

3. Soak the seeds in warm water at about 50 degrees, heat them after the water is cool, heat them when it is cool, and repeat three times. Pinch the seeds and soften them

4. When sowing on a high bed, the distance between seeds is 20 cm or more. A sowing pit can plant about 20 seeds and cover the soil two cm above. If possible, it can be used as topsoil

5. Cover the seeds with straw mats after planting them. Soak the high bed with water until the soil is wet. After that, the time of water supply should be determined according to the wettness of the soil. It can sprout in about 20 days to a month. Then strengthen the management of water and fertility
