Queen Nina grapes can be grown in Guangxi.

Queen Nina grapes can be grown in Guangxi. Queen Nina has not yet entered the mainstream grape production in China. It is planted in small areas in Honghe and Binchuan, Yunnan, and the average purchase price is 50-60 yuan/jin. At present, in terms of cultivation, Queen Nina has 2,000-3,000 bunches per mu, about 30-50 grains per bunch, the weight of a single bunch is about 500-700g, and the yield per mu is about 3,000 kilograms.

Queen Nina, also known as Queen Nina, is a red extra-large-grained European and American hybrid breed cultivated in Japan. It is a tetraploid. It is a bright red, giant-grained variety among European and American hybrids. It tastes great. The sugar content can reach 25-27 degrees, and it has both strawberry and milk aromas. It tastes like an upgraded version of Kyoho grapes. Compared with Kyoho grapes, it tastes sweeter, has a stronger aroma, and has better hardness.

The average single grain weight of this variety is 15 grams, which can reach more than 17 grams. The average single ear weight is 580 grams, which can reach 1200 grams. This variety has 30 fruits per ear and is treated with enlarging hormone. , the fruit pieces can be close to the size of table tennis balls, and after denuclearization, the quality is better.

Cultivation methods and techniques:

1. Since the cold resistance of Queen Nina grape is relatively weak, the climate and cultivation location may affect the phenomenon of grape sound and fruit shrinkage, so If it is not suitable for planting in cold areas, then the temperature and moisture of the planting place must be moderate before planting. Do not choose the location blindly. In addition, during the fruit expansion period, it is necessary to pay attention to the stable dryness and humidity of the soil. If it is too large, it will also cause fruit shrinkage.

2. Lighting and yield are key measures to obtain bright red fruits, so the load must be strictly controlled. The weight of each bunch is controlled at about 500 grams. The length of the spike produced by shaping the flower spike during flowering is When the fruit size is 3 to 5 cm, it is appropriate to thin the fruit to a bunch of about 30 seeds, and the output is appropriately controlled to about 1.2 tons. When pruning, use a seedless method to produce long-tip pruning, leaving flower spikes twice the final yield when flowering, and cut the flower spikes in half during fruit thinning.
