Temperature management 1. Strawberry growth temperature: Most of the strawberries in the greenhouse have already bloomed, and the first ear fruits have begun to mature. The temperature in November is also gradually decreasing. In the winter management of the greenhouse, attention must be paid to heat preservation. Strawberries are low-temperature crops, and temperature differences are also required. The normal growth temperature of strawberries is 8-10 degrees at night, and 25-28 degrees during the day is the best.
2. Strawberry heating and cooling: everyone must pay attention to the closing time of the greenhouse air outlet, because when the air outlet is closed, the temperature in the greenhouse will increase by 2 degrees-3 degrees. When the temperature drops in the winter, the air vent should be closed in advance in the afternoon for thermal insulation. When the weather is clear during the day, the temperature in the greenhouse rises quickly, and the temperature at noon generally exceeds 30 degrees. It is necessary to release the wind in time to reduce the temperature in the greenhouse. The temperature in a greenhouse is different. You can hang thermometers in the greenhouse to compare the temperature.
Humidity management 1. Significance of reducing humidity in strawberries in the greenhouse: During the growth of strawberries in the greenhouse, humidity management is very important and has a great effect on preventing diseases. Too much humidity in strawberries can easily spread the disease. Everyone knows that plant growth requires photosynthesis and respiration. When the leaves produce nutrients through photosynthesis during the day, and respiration at night, the humidity in the greenhouse is very high in the morning.
2. Methods for reducing humidity in strawberries in winter greenhouses: When the humidity in strawberry greenhouses rises, there are many ways to eliminate them. For example, the top seal of the greenhouse can be opened, and the side seal can also be opened to prevent moisture and moisture when it is severe. Plants such as straw and rice husk can be placed in the greenhouse to absorb moisture, and a large number of lime buckets can be placed in the greenhouse to absorb moisture.
