The cultivation of autumn eggplants in autumn and winter in greenhouses can reduce the supply of eggplant in the market after frost. Because the eggplant itself is so hot and afraid of the cold, the normal production is mostly from cold to hot, from long sunshine hours to long sunshine hours. However, the conditions of temperature and light during the production of autumn and winter alfalfa are just the opposite to those of normal production. Therefore, the farmers should strengthen management. Sunlight greenhouse dark winter pod eggplant colonization period in early September. Planting and selecting the plots of solanaceous vegetables for 5 years, 5000 kg of high-quality farmyard manure and 50-70 kilograms of diammonium phosphate were used as base fertilizer, deep-turned and mixed, and cultivated in large and small rows. About 2000 cultivars were planted in acres. One day before planting, the seedbeds were flooded with water. When the seedlings were raised, they were injured as little as possible to ensure a complete seedling. Choose sunny or cloudy evening assault and planting, with the planting along the ditch to pour water to prevent seedlings fight. When greenhouses are planted in autumn and winter in greenhouses, the shed films in greenhouses in most regions are not yet buckled, and there is a period of long or short open ground growth. In the management, we must focus on the following aspects: After planting water, we should grasp the cultivator. After 4-5 days, pour a gentle seedling water, and then grasp from deep to shallow, from near to far, repeated cultivator 2-3 times, and pay attention to ridge soil, after the rain loose soil in time. After easing the seedlings, spray 4000-5000ppm of chlormequat or auxinone (2 kg of water and 10 kg of water) to promote early results. Sulfurous sodium bisulfite (photorespiratory inhibitor) was sprayed once every two weeks before and after flowering of the tomato eggplant. When the tomato was opened, 50ppm of water-soluble anti-decantin and 20ppm of gibberellin were sprayed once. Spray killing agent to control red spider, tea-sweetness and other pests. When the average temperature on the day reaches 16°C-18°C, grasp the membrane (purple or white film). Do not completely seal the membrane during the initial period. Afterwards, as the weather turns cold, it gradually reduces ventilation, gradually adapting the eggplant to the greenhouse environment until it is sealed. Post-buckle membrane management includes: spraying or smoke agent fumigation, further removal of insect pests, so as to avoid leaving or less residual insects; continue to deal with flowers with anti-dropping; double stalks pruning; the result period every 1-2 times to catch water once fat. The temperature in the greenhouse shall not be lower than 15°C in principle. When the temperature is not guaranteed, the grasshoppers and paper quilts shall be promptly stamped and grass shall be covered at the bottom of the front slope of the greenhouse and the back slope, and if necessary, the temperature shall be temporarily replenished. Regularly clean the shed film, uncover the grasshopper timely, and try to create light-temperature conditions that are conducive to the eggplant's flowering results. Timely ventilation and humidity, daytime temperature does not exceed 30 °C. Regular medication, do a good job of disease prevention. Eastony Industries (NingBo) Co., LTD. , https://www.eastony.com
