The latest ventilation management points of strawberry greenhouse

Strawberry is a very common vegetable in our daily life. In China, the planting area is also relatively large, now strawberries are generally planted in the greenhouse, when planting strawberries in the greenhouse, because it is in a space, so we need to do a good job of ventilation. So how to ventilate the strawberry greenhouse? What should we pay attention to in ventilation? The following editor brings you the main points of ventilation management of strawberry greenhouse, let's have a look!

1. Ventilation management

When growing strawberries in the greenhouse, many people do not pay attention to the ventilation of the greenhouse. I think all I need to do is to open the vent. In fact, he also has some skills in ventilation. For those who have the conditions to collect, they will choose the film winder to operate the tuyere, and there is no big problem. But if it is manual ventilation, then there are many places we need to pay attention to, there must be a correct ventilation operation.

First of all, we should keep the vents open and closed all the time. If the opening and closing width of the vent is inconsistent, then the temperature in the greenhouse can not be kept uniform, which can easily lead to a large temperature difference in the local temperature. Therefore, when we ventilate, we should operate according to the specific purpose. If it is cooling, then first open the waist tuyere of the greenhouse, and then open the tuyere at the top. Then when the tuyere is closed, it should be reversed. If it is dehumidification, then the opening and closing order of the tuyere should be the opposite of cooling.

2. Ventilation in sunny days

Sunny weather is relatively high, sufficient light, but the temperature difference between indoor and outdoor will be relatively large, especially in winter. Therefore, sunny days should be dominated by cooling, supplemented by dehumidification. When ventilating, we should always pay attention to the temperature in the greenhouse and adjust the size of the vent with the change of the greenhouse temperature. During the ventilation period, other operations should not be carried out in the greenhouse. Also do not open the vent in place at once to prevent the temperature in the greenhouse from plummeting, which will affect the growth of strawberries. If the vents are to be opened and closed, they should be opened and closed step by step to maintain a stable environment.

3. Continuous overcast ventilation

Many people think that there is no need for ventilation on cloudy days. Indeed, if it is cloudy for about two days, then it can be unventilated. However, if it is cloudy for a long time, ventilation should be done well. After cloudy days for about three consecutive days, short-term ventilation should be carried out at noon when there is no rain, keeping it at about half an hour. The main purpose is to remove moisture and change the air to improve air quality. Only in this way can we further promote the growth of strawberry seedlings and enhance the growth ability of strawberries.

The above is a brief introduction to the main points of ventilation management in strawberry greenhouse. That's all for today's introduction. This article is for reference only. I hope it can be helpful to everyone.
