1. Seed collection

We usually start planting in the middle and late October. Generally, we choose strong mother trees that grow faster, bear fruits early and have very good quality. In addition, we should also pay attention to that there should be no diseases and pests on them. Otherwise, it will affect its future emergence, so we must pay attention

2. Post harvest treatment

After picking seeds, we should spread those seeds in the sun. After the peel cracks, we should dry them in a cool and dry place after collecting the seeds. Seed collection should not be too late. Some seeds are too late, and the seed coat splits. After the seeds fall off, it is not conducive to harvest. In the first ten days of January of the second year, we can soak the seed in warm water of about 30 degrees for one day and one night, and then take it out for sand mixing treatment

3. Preparation before planting

When sowing, we usually choose the place with relatively high terrain and leeward and sunny, and the drainage should be better. Therefore, it is best to choose the shade with loose soil and start digging a pit, with a width of about 1m. The depth of the pit is 60 to 80 cm. However, we spread a layer of coarse sand on the bottom of the pit, and then spread a layer of wet fine river sand five to ten centimeters thick

4. How to sow

We mix the seeds and wet sand in proportion and stack them in the pit. The humidity of the sand must be suitable. You can hold it into a ball with your hand and spread it after you release your hand. When planting sand is 20cm away from the ground, cover it with a layer of 5cm thick sand, cover it with soil to form the shape of a ridge, and then insert a straw handle in the center of the pit, which can help it breathe better. Then dig a little drainage around the pit to prevent ponding. Check regularly during storage and prevent the seeds from heating and mildew. In the middle of March, the soil will begin to thaw, put the seed in a place with the wind facing the sun, increase the water appropriately, and maintain the temperature to make it grow faster
