The invention discloses a vineyard green cover cultivation method. The method includes the four steps of sowing pretreatment, sowing, management in the seedling stage and fertilizer and water management. Humifuse euphorbia herb wide in ecological amplitude and high in adaptability is used and cultivated in a vineyard so that the soil structure can be effectively improved, and microenvironment in the vineyard can be controlled. Meanwhile, usage of herbicide in the vineyard can be reduced, and pollution to the vineyard region by chemical herbicide is reduced. By implementing the method, vineyard management in the later stage is extensive and simple, exquisite management and protection are not needed, investment of manpower and material resources can be reduced substantially, and the vineyard green cover cultivation method meets the requirement of modern agriculture development and is beneficial for simplified cultivation management of a vineyard and green and healthy development.
