Pick the full and mature red fruits, knead them in clear water, remove the impurities and shriveled grains from the peel and floating on the water surface, and dry them for standby.
In March to may, when the temperature is 16 ℃ ~ 22 ℃, it will germinate 25 ~ 35 days after sowing.
Autumn sowing is suitable from September to early October. Before sowing, nursery land with better water and fertilizer conditions should be selected as seedling land. Deep ploughing, soil breaking and harrowing are used to make the border, and the border width is 1-1.2m.
The row spacing is 30m.
Mix the seeds and fine sand evenly and spread them on the seedbed, cover the soil with a thickness of 1.2cm after sowing, then cover with grass and water. When 2-3 true leaves appeared, the seedlings began to be thinned and the plant spacing was 10-15cm. Combined with weeding, apply human and animal manure, and spray water on the leaf surface after application to prevent the fertilizer from burning the seedlings. When the seedlings are 15-20cm high, plant them.
It should be carried out from July to August in spring or rainy season, and the branches with full tissue, medium maturity and gray green skin more than one year old should be cut as cuttings, and the shoots of that year should not be used.
The length of the cuttings was 10-15cm, with 4-5 nodes. The leaves between the 1st and 2nd nodes were cut off to reduce the evaporation of water on the leaves. In order to expand the root surface and water absorption, the cutting mouth needs to be cut flat, so as to improve the survival rate of cutting.
When the temperature is 18 ℃ ~ 25 ℃, 35 ~ 40 natural roots will be planted. If the temperature is lower than 18 ℃, 5 ~ 7 natural roots will be delayed. If the rooting agent "root sun" is used, the rooting will be faster.
Use 350 times of liquid rooting agent and yellow mud to mix into slurry, dip the cuttage cutting mouth into a spot to mix slurry, after treatment, after the slurry is dry, insert it into the seedling pool, when inserting it into the seedling pool, use the stick Jack first, and then insert the seedling, so as to prevent the yellow mud from separating from the cuttings and affecting the rooting effect. The cutting medium can be river sand or yellow mud directly, with a row spacing of 9cmx12cm. After cutting, 70% - 80% shading net shall be used for covering, and then water shall be poured through, and then water shall be sprayed 1-2 times a day to keep the soil in the bed moist. The temperature is 18 ℃ ~ 25 ℃, and the roots can grow 20 ~ 25 days after insertion.
Generally, a part of the aged branches will be peeled or cut and buried in the soil. When they are rooted and germinated, they can be planted after stripping in late autumn or next spring.
