It is relatively easy to cultivate eggplants in the greenhouse in winter and spring, and the economic benefits are also relatively high. This quail eggplant is usually planted in the middle and late October. It is harvested in the middle and early March, and harvesting is completed in June and July. It is an important gargle for solving the early spring and early summer aubergine market supply. The results of the period to strengthen the following management:
The pre-management is mainly based on insulation, which should not be lower than 15°C during the night and 35°C during the day. Can not only consider the insulation and neglect the ventilation and humidity, high temperature and humidity can easily lead to plant leggy, unfavorable results. In the early stage, the water should be properly controlled. When the "open eyes" of the door tomato are opened, the top-dressing watering will be started. Generally, 15-20 kg of compound fertilizer will be applied in the mu. 2 days before and after flowering. Winter and spring quail eggplants generally take double stalks and twigs, hanging with ropes. Timely cleaning of the lower old and yellow leaves in order to improve the interpenetrating conditions, reduce nutrient consumption, speed up the results, and promote premature.
During the growing period of the phytophage, it is known that the temperature is 25°C-30°C during the daytime, 16°C-17°C in the middle of the night, and 10°C-13°C in the middle of the night. When the average temperature is 20°C, it can be harvested in 25-30 days. When the door and the eggplant are swollen, they cannot be short of water. To prevent the greenhouse humidity from being too high, it is possible to water the ditch separately, stop the 2-3 days of cultivating the loose soil, and then pour another ditch. When the eggplant is swollen, it is watered again, and 10-15 kg of urea is flushed with water. After the harvesting of the door, after entering the full fruit period, the outside temperature has been high to prevent the harm of high temperature and high humidity, and at the same time, water and fertilizer management must be strengthened. In general, we need to see the wet surface and dry water once. This period can be sprayed with a mixture of 1% urea + 0.5% potassium dihydrogen phosphate + 0.1% adenosine for extra-root fertilizer, 7-10 days 1 time.
After the average temperature on that day has stabilized at 15°C, the greenhouse can be ventilated day and night, and it can be used in combination with watering several times to dilute into manure, 1,000-1,500 kilograms per acre. At this time, the use of large-scale fertilizers and chasing fecal dilute to accelerate the formation of yields will prevent premature aging of plants and prolong the outcome period. After the minimum temperature stabilizes at 15°C, the film can be removed and the collection can be cleaned.
Cracked eggplant sometimes occurs, mainly due to the hazards of the tea tree borer, which causes the pericarp to thicken and roughen, while the inner placenta continues to develop, resulting in a short period of internal growth; during fruit enlargement, the drought hardens the peel, and then suddenly Watering; late in fruit development, soil is dry and water is not available. Farmers should pay attention to the prevention and treatment of tea locust larvae, which can be sprayed with chlorpheniramine and other agents. The result should not be short of water, even watering.
