How to manage the strawberry?
The cultivation of strawberry temperature and humidity in facilities is the focus of strawberry cultivation management in winter. Many people think that strawberry temperature and humidity management is simply to follow the strawberry temperature and humidity requirements, and it can be controlled by turning the air outlet on and off in time. In the actual production, many of the wind management operations are not scientific and reasonable. Combining my experience of more than ten years of facility cultivation, I will talk about some tips and small details on the management of the wind, and hope to help the majority of growers.
First, the correct air release operation:
It may be that many people say that they don’t think it is easy to open the wind, thinking that it’s not as simple as opening the air outlet. In fact, it is not a good idea to release the wind. If the tuyere is operated by a film rolling machine, the problem is relatively small, but many greenhouse greenhouses are mostly manually operated. Here we mainly talk about the correct air blowing operation by manual manual operation:
1. The opening and closing width of the tuyere should be the same. It is not possible to open and close the width of the air outlet, which may cause uneven temperature in the facility, especially to avoid the wind and the wind.
2, the greenhouse cooling to open the air outlet, should first waist air outlet, rear top air outlet; after cooling down, close the air outlet, first wind outlet, rear waist outlet. To open the tuyere for the purpose of moisture removal, the top air outlet and the rear waist air outlet should be opened first; after the moisture is closed, the air outlet should be closed first, and then the waist air outlet and the rear air outlet should be first.
The greenhouse is cooled and dehumidified, and the tuyere is opened and closed at the same time.
Second, the sunny wind release operation notes:
Due to the good light and the greenhouse effect of the facility, the temperature difference between indoor and outdoor is large, especially in the cold winter season, the temperature difference between inside and outside can reach 20 °C or above. At this time, the main reason for releasing the wind is to cool down and to drain the water. It is necessary to pay attention to adjusting the size of the air-proof port according to the temperature in the facility at any time. Do not do other management operations indoors, but open the air outlet in place according to experience, so that the temperature in the facility drops sharply, which is unfavorable for growth of seedlings and flowers. . It is advisable to open and close the tuy opening a little bit to keep the temperature in the facility relatively stable.
Third, continuous rainy weather release operation notes:
Most people think that it is not appropriate to operate the wind on a rainy day. It is okay to not let the wind rain for 1-2 days. However, for many days of continuous rain, it is easy to have various problems for a long time. Therefore, continuous rainy days should be It is advisable to carry out appropriate air release operations according to the weather conditions.
After 2-3 days of continuous rainy days, it is necessary to select the rainless noon time for a short period of time (15-30 minutes is appropriate) to properly open the tuyere for dehumidification (to open the top tuyere) and air exchange (open the tuyere and waist outlet) ). Continuously rainy, the air in the closed facility is completely supersaturated for 2-3 days, and once the outside world stops raining, the air humidity flowing outside is less than the humidity of the air inside the facility, so the wind management helps to reduce the humidity and air exchange in the facility. It is conducive to the growth of seedlings.
