Cold air strikes, greenhouse planting should pay attention
Lao du has planted strawberries in two greenhouses, that is to say, for seven or eight years, but because he has not systematically learned about strawberry planting techniques, some problems are completed by experience. Now is the time for cold air to hit. How to manage the temperature in the greenhouse? Lao du went to the plant protection station to find a senior agronomist and invited a senior agronomist to his strawberry planting area to see how to operate.
Temperature control
The senior agronomist said that in the whole process of planting in the greenhouse, the temperature is still relatively important. with regard to strawberries, the higher the temperature of strawberries, the smaller the strawberries will grow, and the highest temperature should not exceed 28 degrees. In fact, the most suitable question for strawberry growth is 25 degrees, which must be kept in mind, otherwise, strawberries begin to change color before they grow up, which greatly reduces our income, so When you see that the temperature in the shed is about 25 degrees, pull the tuyere open as soon as possible, and you must grasp the time.
Temperature control
The lowest temperature should be kept above 10 degrees Celsius. The way to raise the temperature at night is very simple, just use your hands a little harder, that is, when you drop the heat preservation quilt, it will fall twice as much as possible. According to the weather, it will fall on the shoulder of the greenhouse at about 4 p.m., and then drop the insulation completely after sunset.
Temperature control
After listening to this, Lao du said that this method was too simple. Before, it was because it was too troublesome and I didn't think so much. Now I have to do it according to this method, hoping to have a good harvest.
