Anti-Japanese sunburn 1. In the summer and autumn high temperature season, the shade net should be used to reduce the temperature inside the shed and avoid direct sunlight. The shed indoors will be released in time to cool down. If the temperature in the shed is too high, it should be properly irrigated to replenish soil moisture and prevent plants. The body temperature rises and the fruit loses water and the sun burns. 2. Pay attention to reasonable close planting so that the stems and leaves are covered by each Other to avoid direct sunlight. 3. After the disease is found, it should be removed in time. 4. In the process of growth, medium and trace elements should be replenished in time to improve the ability of crops to resist stress. 5. Spraying 6000 times of liquid natural brassin in the hot season has a certain effect on the prevention and treatment of sunburn.
Anti-staining sputum 1. Timely draining and removing stains to prevent plant death due to water accumulation and waterlogging. 2. Timely cultivating. When it can land, timely cultivating loose soil, breaking the knot, improving soil permeability and promoting root development. 3. Timely topdressing. Topdressing with quick-acting nitrogen fertilizer and decomposed organic fertilizer solution is good, and pay attention to proper application; 0.3%~0.5% urea solution, 2% calcium perphosphate leaching solution, 0.2%~0.3% potassium dihydrogen phosphate solution and amino acid leaves can also be used. Foliar spray is applied to promote the normal growth and development of plants and increase vegetable yield. 4. Promptly control pests and diseases. After the disaster, the field temperature is high and the humidity is high, which is suitable for a variety of pests and diseases, and timely inspection and treatment. 5. Replant other crops in time. Due to the disaster-rejected fields, it is necessary to promptly illuminate the sputum, reduce the dark stains, seize the season, and rush to plant fast-growing vegetables or mung beans, red beans and other small grains to maximize the disaster losses. 6. Strengthen the construction of water conservancy facilities and use water reasonably.
During the drought-proof period in the late autumn, water conservancy facilities will be built, and small reservoirs will be built to improve drought resistance. For plots with irrigation conditions, water-saving irrigation techniques such as drip irrigation and sprinkler irrigation are used for scientific irrigation. Flood irrigation is strictly prohibited, water conservation is guaranteed, and key vegetables and water for key periods are guaranteed. Choose drought-resistant varieties. In areas with dry and low water, reduce the area planted with vegetables that require large amounts of water. Properly cover the face. Cover the surface with grass straw in time to store water and keep moisture, reduce water and nutrient consumption, and promote growth. The protective ground can be used to cover the sunshade net to reduce direct sunlight, reduce temperature and reduce water evaporation. (Jia Youjiang)
