How to manage temperature and humidity in greenhouse strawberries

Strawberry is a kind of fruit that we are all familiar with, and it has a certain market in our country. At present, most of strawberries are planted in greenhouse, because greenhouse planting can effectively regulate the environment such as temperature and humidity. Create a good growth environment for strawberries, so as to improve the yield and quality of strawberries. So how to manage the temperature and humidity of strawberries in greenhouse? The following editor will give you a brief introduction, let's have a look!

1. Temperature control

According to the solar greenhouse, after the strawberry buckle shed, if it is sunny. Well, at 10 o'clock every morning, if the temperature is higher than 35 degrees, it is necessary to keep the air out in time to lower the temperature of the greenhouse. Control the temperature at about 30 degrees and keep the temperature at about 15 degrees at night. The minimum should not be less than 8 degrees. If the temperature continues to drop at night, it should be covered with grass to keep warm. When artificially adjusting the temperature of the greenhouse, the temperature should be adjusted by uncovering the grass during the day, ventilating at noon and controlling the size of the vents.

Under normal circumstances, strawberries will enter the budding stage about a month after withholding the shed. After budding, the temperature drops to about 25 degrees, and the optimum temperature at night is about 10 degrees. The temperature should not be too high at night, if it is higher than 12 degrees, then the female and male Rafale will be blocked, resulting in axillary flower bud degeneration. Then the temperature control during flowering is also very important, and we should regulate the temperature reasonably according to the growth stage of strawberries. The temperature should be kept at about 24 degrees during flowering and about 10 degrees at night. When the anther is cracked, the lowest temperature should not be lower than 12 degrees. 14-20 degrees is the easiest, too low temperature will affect anther cracking, resulting in hindrance of pollination and fertilization.

2. Humidity control

After strawberries buckle in the greenhouse, the humidity in the greenhouse will gradually increase. Especially in the morning, the highest humidity can reach 100%, and if the humidity in the greenhouse is too high, it will have a great impact on the growth and development of strawberries. It is easy to cause all kinds of diseases and insect pests, among which soil and strawberry water evaporation is the main reason for the increase of humidity. Therefore, when we are watering, drip irrigation is the main method, which can appropriately reduce the humidity in the shed.

Therefore, if we want to reduce the humidity in the greenhouse, then we should consider all aspects of the greenhouse. For example, do not flood when watering, the soil should not be too wet and so on. And when we reduce the humidity, we need proper ventilation, in this case, there will be a certain contradiction with heat preservation. The humidity is relatively high in the morning, which needs not only to reduce humidity, but also to keep warm. Noon is the best time for ventilation and humidity reduction, and in the rest of the time, ventilation and humidity reduction should be operated on the premise of heat preservation.

The above is a brief introduction to greenhouse strawberries if they manage temperature and humidity. That's all for today's introduction. This article is for reference only. I hope it can help you all.
