Strict control of strawberry flowering temperature in greenhouse

The flowering temperature of strawberry should be controlled at 20-25 degrees during the day and 8-10 degrees at night. At this time, it is winter, the humidity in the shed is large, and the air humidity should be controlled as much as possible to facilitate the bee pollination. The temperature during the expansion period should be controlled at 20-25 degrees during the day and 5-8 degrees at night. The harvest period should be controlled at 20-22 degrees during the day and 5-8 degrees at night. This period keeps the temperature lower, which is conducive to the accumulation of strawberry nutrients. To promote fruit enlargement, if the temperature is high and the temperature is high, the strawberry is mature early, but the fruit is small and the yield is low. Because different ridges receive different light levels, the temperature requirements are also different. In order to reduce the temperature difference, the photosynthetic nutrient film fertilizer can be sprayed to help the plants absorb light energy, light fertilizer, and photosynthesis to facilitate strawberry temperature control.
