Brassica oleracea L. (White Cabbage Group)
For this crop, the concept does not mean protecting the plant from frost in the field. The term refers either to overwintering sites for pests or to materials used for protecting pre-winter sowings.
In the reference 87 varieties crop White cabbage, where this is mentioned in the description.
In relation to white cabbage, "winter cover" is not a method of preserving crop vegetation. The term most often refers to the overwintering sites of the crucifer flea beetle, such as plant debris or forest litter, from which the pest migrates to young plantings in the spring.
In pre-winter sowing agrotechnics, covering materials are used to protect seeds and seedlings. The use of mulch or spruce branches helps regulate soil temperature and prevent premature seed germination during thaws, while non-woven materials protect young seedlings from insects.
