Before and after planting vegetables in the greenhouse in early spring
1. Formulated fertilization. The base fertilizer used for vegetables in protected areas in early spring must be fully decomposed. Otherwise, direct application of insecticides can easily induce infectious diseases and insect pests. Heat energy produced by fermentation can damage roots and sprouts, and harmful gases such as ammonia gas can cause 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. Fruit, vegetables, and vegetables should use fertilizers with a balanced ratio of nitrogen, phosphorus, and potassium. 2. Timely planting. For the planting of seedlings of vegetables in protected areas in early spring, the principle of “cold-tail warmer†should be mastered. After the cold weather, sunny and hot weather lasting for more than 4 days is appropriate, so that the ground temperature can be continuously and steadily rebounded. After planting, it will help to quickly rejuvenate the seedlings. In order to facilitate the recovery of vegetable seedlings as soon as possible. 3. Control temperature. Before and after the planting of the seedlings, the greenhouse must maintain a high temperature, which is conducive to slow seedlings. 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. Disclaimer: Some articles in this website have been transferred from the Internet.
