Cultivation management method of early-spring potato seed production

The invention belongs to the technical field of potato breeding and discloses a cultivation management method of early-spring potato seed production. The method includes steps: paving horticultural ground cloth on the ground of a green-net house, applying a nonwoven nutrient bag, preparing a nutrient matrix, planting two layers of matrix in a layered manner, managing pesticide and fertilizer, regulating in the flowering period, controlling temperature and humidity in the green-net house, and preventing and controlling disease and pest. Growth characteristics of potato plants different in variety are combined, a seedling culture matrix is prepared scientifically and reasonably, growth environment conditions are adjusted artificially, growth vigor of introduced resource materials or premature varieties is improved effectively, the defect that the potato plants are poor in early-spring growth vigor, do not flower and are prone to flower falling and bud flowering after pollination is overcome, and fruiting rate o
