When the fruit is ripe, the seeds can be removed from the middle. Before sowing, it should be treated, because the shell is hard, if not treated, it is difficult to sprout and survive. You can wrap the sand with wet sand, put it in a sunny place, use high temperature to promote germination, or soak it in warm water, soak the seeds in warm water, cool them for 2-3 hours, then pull them out, cover them with wet cloth and put them in the greenhouse to promote germination, wait until the seeds have cracks, then you can sow.
Different regions have different sowing time. North China can be planted in the middle of April, while Northeast China can be planted in the first ten days of May because of the cold climate. Before sowing, select a suitable substrate, and then put the seeds in it. The navel should be placed on it, covered with a thin soil of 2-15cm, and then pour water into it.
In the later stage, the seedlings will grow gradually. When the seedlings are in full growth, they should be watered less to avoid water accumulation. If there is too much water, it will lead to decay and death. But also appropriate fertilization, more application of phosphate fertilizer, so as to prevent overgrowth.
Optional in spring and autumn planting, first dig out the small pit, and then plant the plant upright, the root part to stretch.
