Grape wintering tube

The management of grapes before winter is an important part of the annual management. Combining with the actual conditions in the production process, the following cold winter measures can be adopted:

Winter scissor cuts winter cuts before winter to reduce evaporation of winter shoots. It is necessary to pour water once a day to maintain the water's need for weak activity in the roots in winter. During the winter period, every half-month must be checked once. If it is found that the soil is dry, it should be watered in time, but ice and snow should be avoided to avoid excessive water temperature.

Fertilizer In order to ensure robust plant growth in the coming year, it is possible to combine some of the fermented organic fertilizers during winter cutting. Note that the amount of fertilizer used should not be too much. It is generally sufficient to supply 100 grams of grapes per person. The base fertilizer used should not be in direct contact with the grape root system.

Cold insulation (1) Bundle cover cold protection method. Combine the pruned grapevine vines into bundles, and then wrap 1-2 layers of straw or sackcloth on them. Then, cover 15-20 cm thick sawdust, and then cover it with a layer of plastic film. The soil around the film is compacted with soil. . (2) Covered soil ice. Put the bundled grapevines on the ground after trimming, cover the straw bag on the vines, cover the soil with 5-8cm, and cover the soil with 1 straw bag. When the temperature dropped in November-December, two layers of water were continuously poured onto the cover to make it ice, thereby isolating the plants from the outside and achieving the goal of safe wintering. (3) Four layers of sand, film, leaf and straw to prevent cold. That is, first cover 20 cm thick on the vines, cover a layer of plastic film on the sand, lay a layer of 10 cm of corn leaves on the film, and apply 60 cm thick corn stalks on the leaves to provide sand, vines, and membranes for moisturizing. Leaf encryption, straw warm effect. The first three floors should be covered in mid-to-late October. The first layer should be carried out about mid-to-late November after freezing.
