First, the preparation of nutritious soil The screened river sand and soil can be well mixed with a 1:1 ratio. The river sand is required to be clean without any pollution, and coarse sand is preferred, and it is advisable to prepare the soil with topsoil in the field. Second, bagging Nutrition bags can use 15 cm 8 cm polyethylene film bags. Before bagging, cut 1 cm diameter holes in the two corners of the bag to facilitate water circulation. When bagging, the nutrition bag is required to be filled with compaction and placed vertically and neatly in the nursery pond. Third, the laying of electric hotbed 1. Use a 1000 watt geothermal hotline with a length of about 100 meters. Check whether electricity is available before use and remove bad hotline. 2. Make 31.7 meters of rice dumplings, and lay a layer of grass curtains or wheat straw at the bottom to facilitate the insulation, top the mulch, and make holes in the membrane to facilitate seepage. 3. Geothermal lines are laid on the mulching film. The geothermal line spacing is 4-5 centimeters, and the geothermal lines are evenly distributed with no overlap. 4. Place a 12-centimeter thick clean river sand on the ground heating line, spread out and sprinkle water, and maintain the humidity in the hotbed. Fourth, cuttings cut After the stored shoots were removed from the sand pit, they were sorted and selected to select short internodes, full shoots, no mildew and damage, and 1-year-old shoots with a diameter of 0.8-1.3 cm were cut by 2-3 buds. When cutting, the terminal buds must be full-filled buds, cut 1-1.5 centimeters from the upper buds, and cut under the cuttings near the joints. Because the nutrients stored inside the diaphragm are more, it is easy to form callus and occur. New root. Five, cuttings soaked Cut 20-30 pieces of the cuttings into bundles. Bundles require that all the cuttings be placed in the same way, and the cuts should be flushed together. Then the bundled cuttings should be soaked in water for 12-24 hours. The cells are swollen with water, store nutrient hydrolysis and endogenous hormone activation. Six, cutting 1, before the cuttings will be filled with a nutritional bag first poured a permeable, with pouring with the plug. 2. Insert the selected plug straight into the center of the nutrition bag. The cutting depth should be 5-8 cm, and the cutting tip should be exposed outside. 3. When the cuttings are cut, the end buds are uniformly cut to the lighting surface, which is conducive to uniform sprouting of the cuttings, and can also prevent overlapping of the branches after the cuttings sprout. 4. Pour water 1 times after filling. It is best to use spray when watering so that the nutrient soil is in close contact with the cuttings.

5. Spray 70% thiophanate-methyl 800 times once after cutting. 50% carbendazim WP 800-1000 times to kill the latent bacteria on the cuttings.
