In the winter, the main task of vegetable farmers is to make daily use of greenhouses for vegetables. The task of sheltering winds in greenhouses seems simple, but if the timing of the winds is unreasonable, it will cause serious damage to the crops. Many vegetable farmers think that ventilating the greenhouse is to regulate the temperature inside the greenhouse. However, this is not the case. According to the greenhouse greenhouse manufacturers, the reason why farmers are required to regularly give shelter to the greenhouse is not to adjust the temperature. One of the several adjustments of the release of air is to promote the photosynthesis of your crop.
Winter vegetables greenhouse release
Regarding its specific role, the greenhouse greenhouse manufacturers said that the regulation of temperature by air release will indirectly affect the photosynthetic rate. Studies have shown that the photosynthetic rate increases with the increase of temperature, such as vegetables at 20 °C, twice the photosynthetic rate at 10 °C, 30 °C when it is twice the 20 °C, so in good lighting conditions, For thermophilic vegetables, adjust the temperature to 24-30°C. Of course, it is not necessarily the higher the better, and the optimum temperature is different depending on the type of vegetables.
The most important thing is to pay attention to the regulation of photosynthesis during the time of release. In greenhouses of vegetables, more carbon dioxide will be accumulated in the evening, and due to the closure of greenhouses in the evening of winter, the carbon dioxide in the evening sheds will be accumulated to a very high concentration. If we can make full use of these carbon dioxide supply photosynthetic penthouse needs, it will greatly increase the number of photosynthetic products, significantly increased vegetable production. This requires the vegetable farmer to take care that the wind cannot be released prematurely, so as to prevent the carbon dioxide in the shed from escaping the shed and be wasted.
Vegetable green house manufacturers believe that, after opening the shed on the shed, in a good light conditions, the shed to accumulate one night of carbon dioxide, shed vegetables in an hour or so of the need for photosynthesis, so even if the temperature conditions suitable to release the wind Do not let go of the wind within an hour after the shed is opened. It is wrong to let it go. Premature air release will spread part of the carbon dioxide out of the greenhouse. In fact, it reduces the amount of photosynthate produced, and the yield of vegetable farmers is not obtained.
