Grapes winter cold
A: Perform winter cuts before winter to reduce the evaporation of water from winter vines. Pour water once to ensure that water is stored in the roots and maintain the ground temperature. Follow organic fertilizer to promote its robustness. Insulation of the tree body can be achieved by placing the bundled grape vines after pruning on the ground, covering the grass vines on the vines, covering the soil with 5 to 8 centimeters, and then covering the soil with a layer of straw bag. When the temperature drops from November to December, the sand on the ground can be covered with 20 cm thick sand, covered with a layer of plastic film on the sand, and a layer of 10 cm corn leaves can be laid on the film. The pressure on the leaves is 60 cm thick. The corn stalks have the effect of cultivating sand, mulching, moisturizing the leaves, encrypting the leaves, and keeping the straw warm.
