1、 How to breed

1. Cutting propagation: cutting can be carried out after falling leaves in autumn or before budding in spring. Before cutting, it is necessary to apply base fertilizer and disinfect the soil to improve the survival rate. In autumn, cutting and cutting should be carried out at the same time. In spring, cutting strips can be stored in winter or cut at the same time. It is best to select branches above 0.5cm and connect them into cuttings 15-20cm long. The upper cut should be flat, and the lower part near the bud eye should be cut into horse ear shape, which is conducive to faster rooting of cutting. When cutting, the row spacing shall be 30cm, the plant spacing shall be 20cm, the scion shall be slightly exposed to the ground, and then the soil shall be covered and compacted, and then irrigated with water

2. Grafting propagation: in the middle of March, when the budding weather is sunny, cut it at the smooth place of about 2m of the rootstock, leave about 5cm and 2-3 scions full of buds, cut the bottom of the scion into a horse ear shape, and then vertically insert it between the cortex and xylem, and then wrap it tightly with plastic cloth without air

2、 Can you reproduce with seeds

You can reproduce with seeds. You can use the seeds of strong mother trees that are 15-30 years old. When their seeds turn yellow and white, they can be harvested. When breeding with seeds, select sandy soil with water source, good drainage and thick soil layer as nursery. The ground preparation shall be fine and sufficient base fertilizer shall be applied. After shallow turning, it shall be irrigated with enough bottom water before sowing. The sowing method can be border sowing or ridge sowing. Then in the middle of April, the seeds are sown in time after drying in the shade or on a cloudy day. When sowing, it is best to cover about 1cm of soil with a row spacing of about 30cm
