Detailed Explanation of Key Points for Ventilation Management in Strawberry Greenhouses
Strawberry is a very common fruit in our daily lives. Its planting area in our country is also relatively large, and now strawberries are generally grown mainly in greenhouses. When growing strawberries in greenhouses, because they are in an enclosed space, we need to do a good job of ventilation. So how should strawberry greenhouses be ventilated? What should be noted during ventilation? Below, the editor brings you the key points for ventilation management in strawberry greenhouses. Let's take a look!
1. Ventilation management
Many people do not pay attention to greenhouse ventilation when growing strawberries in greenhouses. They think it is enough to just open the vents, but in fact ventilation also involves certain techniques. For those who have the means, they all choose film-rolling machines to operate the vents, and there is not much of a problem with that. But if ventilation is done manually, then there are many places that require our special attention, and a correct ventilation operation is needed.
First, we must keep the opening and closing of the vents consistent. If the opening and closing widths of the vents are inconsistent, then the temperature inside the greenhouse cannot remain uniform, which easily leads to large temperature differences in local areas. Therefore, when ventilating, we should operate according to the specific purpose. If the purpose is to lower the temperature, then first open the side vents of the greenhouse, and then open the top vents. Then when closing the vents, do it in reverse order. If the purpose is to remove moisture, then the order of opening and closing the vents should be the opposite of that for cooling.
2. Ventilation on sunny days
Sunny days are relatively warm with sufficient light, but the temperature difference between indoors and outdoors will be relatively large, especially in winter. Therefore, on sunny days, the main focus should be cooling, with moisture removal as a supplement. When ventilating, pay constant attention to the temperature inside the greenhouse, and adjust the size of the vents as the greenhouse temperature changes. During ventilation, it is not advisable to carry out other operations inside the greenhouse. Also, do not open the vents fully all at once, to prevent a sudden drop in temperature inside the greenhouse that could affect strawberry growth. The opening and closing of the vents should be done gradually to maintain a stable environment.
3. Ventilation during consecutive cloudy days
Many people think that ventilation is not needed on cloudy days. Indeed, if the cloudy weather lasts about two days, then ventilation can be skipped. But if the cloudy weather lasts for a long time, then ventilation work should be done well. After about three consecutive cloudy days, short-term ventilation should be carried out at noon when there is no rain, kept at around half an hour. This is mainly to remove moisture and replace the air, improving air quality. Only in this way can the growth of strawberry seedlings be further promoted and the growth capacity of strawberries be enhanced.
The above is a brief introduction to the key points for ventilation management in strawberry greenhouses. That is all for today's introduction. This article is for reference only, and I hope it can be helpful to everyone!
