Affected by the rainy weather in this year's growing season, the vines in the open-air grapevines are greedy and their organization is not fulfilled, which brings potential hidden dangers to normal wintering. As early as the beginning of winter is approaching, the temperature in most areas is rapidly falling. Especially in the cold regions of northern China, how can we ensure that open-air grapes safely pass winter? According to the production practice experience, the manuscript has been compiled to readers. First, timely off-pruning Pruning late autumn and early winter temperatures are low, and the wind is strong, especially in this year's climatic conditions, the grape branches have high water content, and it is easy to increase the evaporation due to the wind. After the grapes are defoliated, they are trimmed according to the proposed yield indicators and then tied with straw ropes or plastic ropes. Second, timely buried According to the local weather forecast and field observations of temperature changes, when the minimum temperature is stable at about 2 °C for five consecutive days, began to cover the cold. When you buried, pay attention to the root of the first 30 cm height of the mound, and then the vines along the line to the collapse. And then buried up, the first time the buried should not be too much, so as not to expose the dendrite as a standard. Third, timely irrigation of grapes buried, they should pay close attention to a cold water, the purpose is to prevent root damage and early spring drought. When irrigation, one-time irrigation should be performed, and the soil should be saturated. Fourth, adjust the thickness of buried earth and cold-proof materials Cold areas should pay attention to the second time the buried cold, some species that are not tolerant to low temperatures, should be buried in the second cold-proof soil before freezing, buried soil thickness is generally 15 cm. In order to achieve a better cold-proof effect, when buried in the second cold-proof soil, it can be covered with corn stalks or weeds and then buried. In this way, the temperature of the soil at the base of the grape roots can be significantly increased, which is conducive to safe wintering of the grapes. Fifth, the plastic film weeds cold winter temperature is not very low in the microclimate areas, can be overwhelmed grapes covered with plastic film grape vines, and then weeds, corn stalks, horse dung and other cold-proof materials covered on the membrane. Finally, pressing a thin layer of soil on these coverings not only prevents the wind from blowing off weeds, ensures the insulation effect, and achieves the goal of safe wintering, but also eliminates possible fire damage.
