Spring greenhouse vegetable scientific management method
(1) Reasonable temperature control. In spring, the temperature rises rapidly, the temperature changes greatly, and the indoor temperature is too high or too low, which is unfavorable for flowering and fruiting. It is easy to form deformed fruit or fallen flowers, and temperature management should be based on reasonable temperature control. Temperature management is mainly based on heat preservation in February. After entering March, with the rapid increase of temperature, it should gradually turn to reasonable temperature control. Generally, when the temperature in the shed rises to 25-30 °C, the wind should be released, and attention should be paid to gradually increase the ventilation as the outside temperature rises gradually. (2) Reasonable topdressing. Timely topdressing is conducive to the nutrient supply during the normal growth of vegetables, pay attention to balanced fertilization, increase the amount of phosphorus and potassium fertilizer application, and improve the quality. Spraying fertilizer on the leaf surface with the fruit juice and strong spirit liquid can strengthen the seedlings and strengthen the nutrient transport to achieve the effect of preventing premature aging. (3) Integrated pest management. The main disease in the greenhouse is gray mold disease, which is controlled by the smoke fumigant-speed Keling and chlorothalonil. Then the new high-fat film powder is sprayed on the surface of the vegetables, which has good fungal diseases for various plants. Control effect is conducive to controlling the spread of diseases, reducing the number of pesticide sprays and saving pesticides; of course, attention should also be paid to leaf mold, downy mildew, powdery mildew, root rot prevention and aphids, cabbage caterpillars, red spiders, thrips The harm of pests.
