Abstract

The invention relates to a cold-proof method of grape, in particular to an overwintering and cold-proof method of outdoor grape. The method is characterized by comprising the following steps of: a. preparing a polystyrene foam grain carpet; and b. paving the polystyrene foam grain carpet under an outdoor grape bracket. The method is unique, is applied to the outdoor grape in the rest period in the North China, adopts the material which is low in price, good in heat preservation, light in weight, low in water absorption, labor-saving, time-saving, and easily paved and furled for preventing late frost in winter, prevents the buds of branches of the outdoor grape in rest period from being frozen and covered, prevents the branches and tendrils of the outdoor grape in rest period from losing water, and prevents the roots of the outdoor grape from being frozen due to the temperature in the covering material.

Description

Technical field

[0001] The invention relates to a method for protecting grapes from cold, in particular to a method for protecting grapes from overwintering in an open field. Background technique

[0002] Grapes have been cultivated for about 7,000 years. European table grapes (Vitis vinifera L.) originating from the Mediterranean, Black Sea and Caspian Sea coasts are widely cultivated and enjoyed because of their high quality. In the Han Dynasty more than 2,000 years ago, European grapes were introduced to China via the Silk Road. According to my country's grape planting and wine development plan, by 2010, the country's wine grape planting area alone will reach 66,670 hectares. In northern China, due to climatic characteristics, the temperature in early winter drops rapidly, the temperature rises and falls in spring is large, and late frost is frequently invaded. It is required that the burial of soil in early winter and the excavation in spring should be completed in a short ...
