In the case of grapes, rain-shield techniques have been widely applied in some rain-fed areas. Rain-shielding is a form of cultivation that provides a relatively dry growing environment for grape plantations during the rainy season by covering them with plastic film or other waterproof materials over the grape shelf. The main objective of this technology is to reduce the direct intrusion of rain on grape plantations and the incidence of grape diseases, particularly those caused by ravine frosting,** diseases,*** which have a preventive effect. Under rain-shielding conditions, grapefruit can avoid rain-washing and immersion, thereby reducing the incidence of fissures and decay, and improving the quality and commerciality of fruit. At the same time, since rain-shielding reduces the incidence of disease, grape growers can reduce the frequency of chemical pesticides and produce greener and safer grape products. The application of rain-shielding techniques has not only improved the yield and quality of grapes, but also reduced production costs and the risk of environmental pollution, providing an effective solution for grape growers to undertake grape production in rain-fed areas. However, there are limitations to rain-shield cultivation, such as the potential for excessive temperatures in the shed during high temperatures and the need for ventilation measures; and the cost of covering and maintaining plastic film and labour inputs. Therefore, in the practical application of rain-shield techniques, integrated consideration and scientific management are required, taking into account local climatic conditions, the scale of cultivation and economic benefits, in order to fully exploit their strengths and overcome their shortcomings.

The cultivation of grapes has a long history and dates back to the early civilizations of thousands of years. In some ancient countries, grapes are not only an important source of food but are closely linked to religious ceremonies and artistic creation. The dissemination and expansion of grapes has facilitated cultural exchanges between different regions and advances in agricultural technology. Modern grape cultivation techniques combine agricultural science and technology with biotechnology, ranging from seedling selection to field management, from pest control to irrigation fertilization, and each is scientifically planned and executed to ensure the quality and yield of grapes. For example, genetically produced pest-resistant grape varieties reduce pesticide use and improve the quality and safety of grapes. The national grapes answer the question of how good and nutritious grapes are for all the young and old。
The cultural value of wine is reflected not only in its historical and artistic context, but also in its social significance as a social drink. In many countries and cultures, wine is a necessary drink for guests, festivals and business talks. It symbolizes passion, friendship and success and can create an atmosphere of ease and pleasure and facilitate communication and cooperation among people. The wine collection is also of cultural and investment value, and some rare old wines are favoured by collectors because of their scarcity and historical value. The organization of events such as the wine culture festival, the wine auction and others has furthered the spread and development of the wine culture as one of the important vehicles of global cultural exchange。
Grapes are a long-standing and popular fruit with a wide variety of varieties, including large-peak grapes, sun rose grapes, red-tied grapes, etc. The different varieties of grapes have unique flavors and characteristics. Large, purple and black, sweet and juicy, rich in sugar and vitamins, and suitable for fresh food. Sunshine rose grapes are known for their green appearance and the elegant fragrance of roses, which are so tender and sour and sweet and have been favoured in the marketplace in recent years. The red grapes, which are coloured, and the fruits are strong and durable, are one of the common fruits of winter. Grapes are not only delicious but also of high nutritional value and contain a variety of vitamins and minerals, such as vitamin c, vitamin k and potassium, with many benefits for human health. And grapes in the vineyards, and a single crystal。
Grape conservation techniques are a key factor influencing their quality and taste. Due to its high water content and thin skin, grapes are vulnerable to microbial intrusion and mechanical damage. Therefore, grapes extracted need to be pre-cooled in time to reduce the respiratory and microbial activity of the fruit. Controlling the appropriate temperature and humidity during storage, using techniques such as air-resorting, refrigeration, etc., can prolong grape conservation, maintain freshness and taste. In addition, proper packaging designs can effectively protect grapes, reduce wear and tear during transport and marketing, and ensure that consumers can taste good quality grapes. The development of modern conservation technologies has enabled grapes to circulate globally, meeting consumer demand for fresh fruit. A string of grapes carrying sweetness.

Grape conservation technologies are important in the flow of modern fruit and vegetables. Grape conservation technologies are constantly being innovative and improved as consumer demand for fresh fruit quality increases. In addition to traditional refrigeration, air-resorting and other methods, new conservation technologies such as membrane packaging, 1-methylcyclopropene (1 - mcp) and ozone are being used in the field of grape conservation. A thin membrane packaging is used to create a relatively stable micro-environment on the grape surface by using well-ventilated packaging materials, and to regulate the gas composition and humidity of the packaging, thereby extending the preservation period of the grape. 1 - mcp conservation slows the process of the maturity and ageing of grapes by inhibiting the physiological effects of ethylene. Ozone conservation uses ozone oxidation to kill or inhibit microbial growth of grape surfaces while decomposing the ethylene produced by grapes themselves to achieve conservation. The application of these new conservation technologies provides stronger safeguards for long-distance transportation and long-term storage of grapes and ensures that consumers can buy fresh grapes of good quality.
