1、 Seedling preparation:

First of all, do a good job in the seedling bed. The length depends on the specific situation. The reference values of width and height are one meter and fifty centimeters. Drainage holes need to be set with an interval of 0.5 meters. Then lay a layer of bricks at the bottom to facilitate drainage; Lay the substrate on it and choose coarse river sand. Finally, the substrate shall be sprayed and disinfected. Use ash manganese oxygen solution with a concentration of 2.5 thousandths. After half an hour, rinse the substrate with clean water until clean water flows out of the drainage hole

2、 Selection and treatment of cuttings:

At the beginning of July, choose the annual semi lignified branches with short bud spacing as cuttings, with brown green as the top and good flexibility. Measures shall be taken to avoid water loss during transportation. Cut the branches to 12 cm for cuttings. The top is a flat cut and the bottom is in the shape of a horse ear. Usually, twenty branches are bundled together and immersed in the rooting agent solution. The concentration is 500 mg / L. it needs to be soaked for 12 hours for cutting preparation

3、 Cutting:

When cutting, the plant row spacing refers to three centimeters by four centimeters, and about 830 pieces can be cut per square. When cutting, it should be squeezed tightly, and the depth is about three centimeters. After cutting, it should be watered in time. After that, build a plastic shed. It is better to build a shading net on the arched shed to cover the sun and avoid exposure, but the weak light around 7 a.m. and after 6 p.m. should be seen

4、 Post insertion Management:

The key of this link is temperature and humidity control. Before cutting, the spray interval and spray volume control can help to keep the water droplets on the leaves. According to the specific situation, ensure that the water is penetrated twice a day, so as to ensure the humidity of no less than 80%. Usually, after 14 days, partial rooting, and after 20 days, 90% of cuttings take root. Fertilizer should be applied after rooting for half a month. The medicine prepared according to the special formula should be sprayed every ten days. After the cold weather, to protect them from the cold, they can be transplanted, planted and cultivated in the early spring of the next year
