How to manage temperature and humidity of strawberries in greenhouse

Strawberry is a kind of fruit that we are familiar with, and there is a certain market in our country. Most of the strawberries planted now have been mainly planted in greenhouses, because greenhouse planting can effectively regulate the environment such as temperature and humidity. To create a good environment for strawberry growth, in order to improve the yield and quality of strawberries. So how do greenhouse strawberries manage temperature and humidity? The following small series will briefly introduce you, let's take a look together!

1. Temperature regulation

According to the solar greenhouse, after the strawberry buckle in the greenhouse, if it is sunny. Well, at 10 o'clock every morning, if the temperature is higher than 35 degrees, it is necessary to release air in time to reduce the temperature of the greenhouse. Keep the temperature at around 30 degrees and keep it around 15 degrees at night. The minimum temperature should not be lower than 8 degrees. If the temperature continues to drop at night, it should be covered with straw in time for insulation. When artificially adjusting the temperature of the greenhouse, the temperature should be adjusted by removing the straw cover during the day, ventilating at noon and controlling the size of the vent.

Under normal circumstances, strawberries will enter the bud stage about a month after the shed is closed. After budding, the temperature drops to about 25 degrees, and the optimum temperature at night is about 10 degrees. Night temperature should not be too high, if higher than 12 degrees, then male and female Rifal blocked, leading to axillary flower bud degradation. Then the temperature control during flowering is also very important. We should adjust the temperature reasonably according to the strawberry growth stage. The temperature during flowering should be kept around 24 degrees and at night around 10 degrees. The lowest temperature during anther dehiscence should not be lower than 12 ℃. It is easiest to use 14-20 ℃. Too low temperature will affect anther dehiscence, resulting in blocked pollination and fertilization.

2. Humidity control

After the strawberries are buckled in the greenhouse, the humidity in the greenhouse will slowly increase. Especially in the morning, the humidity can reach 100%, and the greenhouse humidity is too large, the growth and development of strawberries is very large. It is easy to cause various diseases and insect pests, among which the evaporation of soil and strawberry water is the main reason for increasing humidity. Therefore, when watering, we mainly use drip irrigation to reduce the humidity in the shed appropriately.

Therefore, if we want to reduce the humidity in the greenhouse, then we must consider all aspects of the greenhouse. For example, when watering, do not flood irrigation, soil should not be too wet, etc. Moreover, when we reduce humidity, we need proper ventilation, so that there will be certain contradictions with heat preservation. In the morning humidity is relatively high, both need to reduce humidity, but also need to keep warm. At noon, it is the best time period for ventilation and humidity reduction. In the rest of the time, ventilation and humidity reduction should be operated on the premise of heat preservation.

The above is a simple introduction to greenhouse strawberries if temperature and humidity management. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
