heating conditions caused by the use of heat-brewed materials in hotbeds to promote rooting. Before rooting, first dig a bed pit on the ground, the bottom of the pit slightly higher, slightly lower around, and then loaded 20-30 cm thick raw horse manure, side-by-side solid, watering after flattening to moisten the horse manure, covered with plastic film, prompting Horse manure fermentation heat, a few days later when the temperature rises to 30-40 degrees C, and then lay about 5 cm thick fine soil on top of horse manure, waiting for the temperature to drop and stabilize at about 30 degrees C, the prepared strips neatly arranged upright on top. Fill branches with wet sand or wet sawdust to prevent heat from rising and moisture from evaporating. The lower soil temperature of the insert is maintained at 22-30 degrees C. Be careful that the buds at the top of the insert should not be buried in the sand to protect them from premature germination due to high temperatures. During the rooting to keep sand or sawdust moist, and pay attention to control the bed surface temperature, during the day will cover the hotbed of plastic film to open, the use of early spring cold air to reduce the bed surface temperature, to prevent premature germination of bud eyes.
