How to Overwinter Garlic in Dezhou, Shandong Province

Covering garlic with plastic film during overwintering can prevent garlic from freezing injury, alleviate garlic diseases to some extent and improve garlic yield. Now briefly introduce this technology:

First, prepare the movie.

According to the width of the garlic field, the width of the film is reasonably selected (the common garlic film width specifications are 4.3m, 4m, 3.5m and 3m, etc.). ), and prepare the equipment for film mulching, and saw 0.3m sticks with bamboo poles or branches, about 1 0,000 sticks per mu. Prepare some plastic ropes, each mu needs 1 ~ 1.5 kg, and cover them at any time.

Second, the preparatory work before plastic film mulching

Check in the garlic field first, and hook out the garlic seedlings without arching out the plastic film with a wire hook. Because of the abundant rain before winter this year, garlic can be watered without overwintering water this year.

Third, plastic film mulching.

After the solar term of heavy snow or when the weather drops below 0℃ (it freezes at night for 3 ~ 5 consecutive days and disappears during the day), film mulching will be started at 9: 00 am on a sunny day. Put a film on the edge of the garlic field, use a shovel to take soil and press it on the put film, then tie 2/3 of the bamboo sticks with plastic ropes and insert them into the soil, and tie another one every one meter or so; And so on, until it is placed on the other side of the ground, and the film is also pressed with a shovel. After the first stage, put the film back in its original position. Note that the overlap between films should not be less than 0.3m Below this value, garlic will be blown by the wind, which will affect the safe overwintering of garlic.

Fourth, attention should be paid to film covering skills

Because there are more winds in the northwest in winter, when the film is covered, the film is covered from the south in the east and from the east in the north and south.
