China's northern spring March-April temperature rebounded faster, while the ground temperature rise is slower, dewy insertion often inserted first germination, after rooting, germination and rooting time difference of more than 20 days, if not properly managed, germination of germination buds often due to water nutrient supply and withering, seriously affecting the survival rate of the insertion. The reason is that grape bud eye germination requires a lower temperature, generally at about 10 degrees C can germinate. Rooting requires a high temperature, and rooting at 25-28 degrees C is the fastest. Rooting is based on the temperature requirements of the grapes when they take root, artificial heating causes the root of the insert to accelerate the division of primitive cells, and promotes the formation of indeterm roots. The commonly used rooting methods in production are hotbed rooting, fire pit rooting, electrothermal rooting and chemical agent treatment rooting.
