The invention discloses a grape
overwintering covering structure and a manufacturing method as well as a use method. The structure is of a multilayer structure and comprises a piece of waterproof cloth, a
greenhouse film, a felt, industrial cotton and another piece of waterproof cloth from bottom to top in sequence. The manufacturing method comprises the steps of smoothly laying the waterproof cloth, the
greenhouse film, the felt, the industrial cotton and the other piece of waterproof cloth from bottom to top in sequence,
cutting out according to required length and width, and then stitching all
layers together through needlework along the circumferences. The use method comprises the steps of
hilling up at both sides of a base of a grape
main stem, so as to form a grape valley with the width of 110 to 120 cm and the depth of 20 to 30 cm, pressing grape branches and tendrils into the valley, cover the grape valley with the
overwintering covering structure, and then compressing, so that a certain space is formed in the grape valley. The grape
overwintering covering structure has the effects that the
water content of the grape branches can be effectively increased in the period of
dormancy, so as to prevent the branches from losing water and
drying and prevent grape roots and the branches from being frozen; when the temperature rises in spring, the temperature rise in the covered grape valley is slower than that in a soil buried overwintering grape valley due to a covering effect, and grapes
delay germinating, so that the capability of preventing late
frost is effectively increased.
