Strawberry in greenhouse should pay attention to the regulation of temperature and humidity

Reasonably topdressing strawberries into the fruit-picking period usually topdresses for about 20 days, and topdressing can be combined with irrigation. This period is the first harvest of strawberry fruit is basically completed, the second batch of inflorescences will appear in the stage, should be appropriate top dressing, fertilizer, quick-acting nitrogen and potassium fertilizer-based compound fertilizer, can be applied 15 kg per acre.

Plant cleaning removes old leaves, diseased leaves and stolons in time to reduce nutrient consumption and often leaves 4-5 functional leaves. Appropriate sparse fruiting and thinning, sparse fruiting stems are too short, flowers are small, fruits are not hypertrophy, and fruits have deformed fruit when large.

Temperature and humidity control to catch the fine weather for necessary ventilation and humidity, increase light. During the low temperature season, the temperature in the shed is kept as much as 20°C to 25°C during the day and 5°C at night. Humidity has a great influence on strawberry flowering pollination, high humidity, pollen germination rate is low, often increase the rate of small fruit and malformed fruit, so try to keep the relative humidity within the shed at 50% to 60%. At the same time, bees are added in time to ensure pollination quality. After the shed has brought cultivation into the spring, the temperature has gradually increased and the temperature in the shed has increased rapidly. At this time, as the temperature rises, the amount of ventilation is gradually increased to prevent the temperature in the greenhouse from being too high. Otherwise, the strawberry fruit will become smaller and less acidic.
