The cultivation of wintering spinach is easily affected by the low temperature in winter and early spring. After the spring is opened, the general varieties are easy to twitch and reduce the yield and quality. Therefore, suitable varieties should be selected for wintering cultivation, and mid-maturing and late-maturing varieties with strong winter, late bolting, strong cold resistance, and high yield should be selected. Such as the selection of round leaf spine, late round leaf spine, Hua Bo No. 1, Liaoning Yuan Ye spindock and other varieties. First, choose to do In accordance with the conditions of the production of pollution-free vegetables, the selection of leeward sunny, loose soil and fertile, good drainage conditions, neutral smiling acidic soil. After the harvest of the previous crop, the new high fat film was sprayed to clean the pasture. Apply basal fertilizer to spray strong stems. The growth period of spinach is longer, and if it does not cooperate with spraying strong stems, the growth of plants before winter is weak, which is not conducive to safe wintering, and prone to convulsions when recovering from growth in the following year. The entire surface is flat and thin, making it 1.2-1. 5 meters wide. Second, the appropriate sowing Seeding seedlings are closely related to seedlings' overwintering ability, harvesting time, and yield, sooner or later, not too early or too late. Spinach has 4-5 leaves before freezing. Overwintering spinach is sown in mid-to late October and early November. At this time the climate is cool, suitable for spinach germination and emergence, generally do not need to sow germinating seeds, sowing dried seeds and wet seeds. Before seeding, seed dressing with a new high fat film can repel insects in the ground and isolate virus infection without affecting the function of germination and ingestion, enhancing respiratory intensity, and increasing seed germination rate. Third, cultivation and management After spraying, strong stalks are sprayed in time, which makes the stems thick, leaves hypertrophy, fresh leaves color, lush plants, and strong natural taste. At the same time, it can increase the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual poisons. If the soil is dry, it can be poured with a small amount of water to keep the soil moist. When 3-4 true leaves are used, the water can be properly controlled to promote the development of the root system to facilitate overwintering. If the seedlings are dense, 2-3 true leaves can be seedling once, and the seedlings are 3-5 cm apart. This period can be based on seedlings and weather topdressing water and fertilizer, mainly to human fecal urine, promote seedling growth. If locust damage occurs, it should be sprayed and controlled in time. In frost and ice and snow weather, timely application of new high-fat film covering film and shade net, floating surface coverage and small arch cover can be. After the temperature rose in the spring, the selected sunny day was followed by the application of composting and faecal spraying to build strong stalks, promote the development of tenderness and strong growth, and prevent early defecating.
