First, master the planting time. The principle of “cold tail warmer†should be mastered for the planting of seedlings of vegetables in protected areas in early spring. After a cold weather, sunny and hot weather lasting for more than four days is appropriate, so that the ground temperature can be continuously and steadily recovered, and the planting will be conducive to rapid seedling growth. , resume growth as soon as possible. Second, scientific formula fertilization. The production of vegetables in protected areas in early spring is a relatively closed environment. It is required that the base fertilizer used must be fully cooked, and the excrement of livestock and poultry must be processed through high-temperature fermentation. Otherwise, direct application of insecticides can easily induce infectious diseases and insect pests. Gas and other harmful gases cause gas poisoning. The combination of decomposed organic fertilizer and chemical fertilizer has the best effect. According to the type of vegetables to be planted, the proportion of fertilizer should be selected. Leafy vegetables should use high-nitrogen, low-phosphorus, and high-potassium compound fertilizers; fruits, vegetables, and vegetables should use fertilizers with a balanced ratio of nitrogen, phosphorus, and potassium. Third, choose age-appropriate seedlings. The quality of vegetable seedlings cultivated by the vegetable growers using the soil warming greenhouse or improved Yangshuo is not high. Before the planting, the seedlings for self-cultivation shall be treated in a graded manner, and the diseased seedlings, aging seedlings, young seedlings and old seedlings shall be eliminated and eliminated, and the most suitable one shall be selected. High quality seedlings. The selection of strong seedlings in production is conducive to rapid seedling growth, and the seedlings have a high degree of uniformity and are conducive to bumper harvests. Fourth, do warming insulation. Before and after the planting of the seedlings, the greenhouse must be maintained at a higher temperature, the higher temperature is favorable to the seedlings of the vegetable seedlings, the wound healing of the damaged roots is healed, and the roots grow rapidly. Pay attention to watching the weather forecast. Before the cold weather comes, it must be covered with grasshoppers at the night or the insulation temperature is increased. On the eve of the strong winds, do a good job of fixing the film to prevent the wind from damaging the film. Snacks usually refer to the food eaten outside the time point of three meals a day.
