Recently, there have been times when farmers and farmers consulted the time and method of wintering garlic double film coverage. Here, the following questions are answered.
Garlic-covered double membrane is a new planting pattern in recent years. After covering double membranes, it can greatly prevent the freezing damage caused by winter cold weather to wintering garlic. At the same time, the garlic covered by the double membrane, due to the influence of the microclimate, effectively shortens the dormancy period of the garlic seedlings, can make the garlic turn green in advance, and plays an important role in the increase of garlic production in the coming year.
The best time to cover the double membrane is the key to affecting the output value of garlic. Premature coverage will cause the garlic to grow vigorously instead of using safe wintering (the plant height of winter garlic is about 20 cm, and the leaves are 5-6 leaves most tolerant to severe cold); Too late, there is no artificial condition to protect garlic from wintering safely. Therefore, the time for covering the double film of garlic is generally selected before or after heavy snow or when the local temperature is continuously lower than 0 ° C for 3 to 5 days.
There are two ways to cover a double film:
One is a film plus a fixing rope and a fixing rod. Choose the appropriate mulch according to the size of the garlic plot (the size of the mulch is 4m, 3m, 2m), and prepare the plastic rope and the fixed rod with a length of about 30cm and a diameter of 1-2cm. Or branches). When the temperature is lower than 0 degrees, 3 to 5 days, after 9:00 am, the mulch is placed on the ground of the garlic field, and then the soil is pressed on the mulch with the shovel, and the plastic rope is fixed. 2/3 of the stick, press hard into the soil, so that 2/3 of the stick is inserted into the soil, taking care not to get too close to the roots of the garlic. Then use the same method to press the second fixed rod about 1 meter away from the first fixed rod. The 4 meter wide mulch can be temporarily pressed into the three fixed rods, and then the ground film is placed, and the ground film is about one meter away from the fixed rod. When it stops, the plastic rod is tied to the fixing rod 2/3 on the first fixing rod, pressed into the soil again, and so on, until it is placed on the other end of the garlic ground, the film is cut off and pressed with soil. The second film is placed again, or the first film is used. Note that the overlap between the film and the film is not less than 40 cm, and is fixed by a fixing rod in the middle of the overlapping portion.
The second is to cover directly with a film. This method is to select the film of the corresponding width according to the width of the garlic field, and then spread the film along the garlic cloves. One person releases the film and the two use the iron shovel on the garlic ridge to press the pressed film on the back. On the other hand, put the soil on the film in the garlic vine every 1~2 meters (be careful not to press the soil on the garlic seedlings when pressing the soil, otherwise the soil on the garlic seedling will affect the photosynthesis of the garlic leaves, so that Serious chlorosis of garlic will cause death). After the film is spread to the ground, the film is broken and the soil is compacted.
No matter which method is adopted, it is necessary to prevent the double membrane from being opened by the strong wind. For the membrane that is not protected by the wind, it should be remedied in time, otherwise it will lose its meaning.
Finally, remind the majority of vegetable farmers, due to the northwest wind in winter, when covering the double film of garlic, it should be noted that the garlic planting is for the south side of the east and west, and the film is placed from the east side to prevent the film and the film from entering the interface. The wind started.
