Facility Agriculture Snowfall Management Measures: When it comes to snowfall, it is necessary to cover a layer of silk felt and cover with a layer of straw mat. After the snow stops, remove the snow immediately to prevent the snow from melting and ensure that the cover is dry to facilitate heat preservation. When the weather began to clear, slowly remove the cover to facilitate penetration into the sun. If the weather is suddenly clear after continuous snowfall, all coverings shall not be removed suddenly and shall be removed in time to prevent "flashing seedlings". After the exposing, we must pay attention to the observation of crop changes. Weeds must be immediately covered with weeds. After the seedlings are recovered, the grass mats are removed. This is repeated for two or three days and then transferred to normal management. Measures against cold damage of fruit trees: 1. The tree protection closely monitors the temperature change, sprays the new high-fat membrane insulation and freeze protection at the right time, and adopts the method of tree wrapping. The main stem and the main branch are wrapped with waste cotton, cloth, crop straw, grass and other articles, and the used agricultural film is used. Woven bags tied tightly. 2. Timely removal of snow from branches The timely removal of snow between branches and branches, spraying of new high-fat membranes to prevent drastic changes in day-night temperatures and ablation of ice and snow, causing freezing damage to trunks and aggravating rot disease. 3, to strengthen the management of the flower buds of frozen apple trees in time to spray a new high-fat membrane, can prevent virus infection, restore plant physiological vitality, and promote plant growth. Spraying foliar fertilizer before flowering and after flowering, using wall bee pollination and artificially assisted pollination, comprehensively increase the fruit setting rate and increase the fruit amount. On this basis, the management of fertilizer and water should be strengthened to promote the robust growth of trees and preserve fruits scientifically to further increase the yield and quality of apples and minimize losses.
