American grapes are resistant to diseases, humidity and cold, but the fruit quality is poor. "Kangke" is one of them, which is mainly used to make juice or brew ordinary wine in the United States. In recent years, European and American hybrid grapes, such as Shifeng, White Banana, Royal Rose, Rose Dew, etc., have good fruit quality, close to European grapes, and strong disease resistance and cold resistance. Among them, "Shifeng" is a medium-ripe food variety cultivated in Japan, belonging to tetraploid hybrid grapes, which are deeply loved by people because of their sweet and cool grains. Generally, the weight of fruit is10-1g, and the large fruit can reach 15 g (while the weight of ordinary grapes is only 5-6 g); The sugar content of fully mature fruit exceeds 18 degrees. In Japan, although the grape production tends to be surplus, the planting area of "Shifeng" grapes satisfying consumers' appetite in this country is still expanding, and the market consumption is rising steadily. In Taiwan Province Province, China, the price of "Shifeng" is obviously better than other small grapes, so the planting area is increasing. The introduction of "Shifeng" in Guangdong and other provinces has also been successful, and it is expected to develop rapidly.
