What are the planting management techniques in the greenhouse on windy days in spring? To learn these three points is to save money!

Although the spring breeze warms people physically and mentally, it will bring some trouble to the farmers who grow in the greenhouse. If they are not careful, it will damage the equipment and increase the planting cost. What are the planting management techniques in the greenhouse on windy days in spring? You can save money by learning these three points!

I. viewing the wind direction from the planting management technology of greenhouse in windy days.

The north wind of level five cannot turn the grass curtain, but the west wind or east wind of level four can blow over the grass curtain. if you want to keep the grass curtain from being blown over after putting the shed, you must use a floating film to prevent the wind, and focus on preventing the easterly and westerly winds.

When placing the shed at night, if the wind is westerly or westerly, for the floating film fixed on the back slope of the shed, the vegetable farmer only needs to press the west side of the floating film, so that the wind will not blow into the bottom of the floating film, and the air in the air bag formed during the floating film can be pressed out, so that the floating film can be pressed against the grass curtain to prevent the strong wind from blowing up the floating film and blowing over the grass curtain. When the easterly wind or easterly wind is blowing, the opposite film pressing method is adopted, and the north side is pressed well when there is no fixed floating film.

Second, the opportunity of planting and management technology in greenhouse in windy days.

In the course of the day, the wind usually rises in the morning and increases gradually, but the wind will gradually decrease in the afternoon, so vegetable farmers can pull the shed ahead of time.

Now the lowest outdoor temperature in the morning is not less than 0 ℃, and the duration is very short, the temperature rises quickly after the sun comes out, and the temperature in the shed will not drop significantly after pulling the shed, so vegetable farmers can advance the shed time to 7 o'clock in the morning (later, as the weather gets warmer, the sunshine time extends, the shed time should be gradually advanced), at this time the wind is generally small, will not blow the grass curtain over.

In the afternoon, the wind gradually decreases, vegetable farmers can postpone the shed time until after 5 o'clock. For the old grass curtain which has been used for many years, in order to prevent the strong wind from overturning the grass curtain, a number of vegetable farmers can put the shed together to shorten the shed time and reduce the probability that the grass curtain will be overturned by the wind.

Third, the view method of planting management technology in greenhouse in windy days.

For the artificial pull straw curtain greenhouse, the grass curtain will hold down the floating film of the greenhouse, so there is no need to worry about the floating film being blown away by the wind. For the greenhouse using the shutter machine, most vegetable farmers roll the grass curtain to the north side of the vent 0.5-1 meter and then stop, and the grass curtain cannot hold down the floating film. If the vegetable farmer rolls the floating film directly to the back slope, it is easy to be blown up by the south wind. Vegetable farmers can roll up the floating film 1-1.5 meters away from the fixed position, roll the folded floating film to the northernmost side of the floating film, fold the unrolled 1-1.5 meter floating film and cover it on the upper part of the rolled up floating film. In this way, even without brick pressure, it can prevent the south wind from floating the film.

It is windy and windy in spring, and many greenhouse grass curtains are blown over by the wind, or the floating film is blown away by the wind. Only when vegetable farmers master the correct greenhouse management technology, can they reduce losses and obtain better benefits.
