Yes, this variety of Cronson grape grows vigorously, and its nutrition grows vigorously, which inhibits reproductive growth, so it is not easy to set fruit, and there are few fruit sets. In production, it is usually planted on the shelf and then planted on the horizontal frame. If it is controlled, it will bear more fruits, and then it will be controlled by chemicals.

First, the characteristics:

1. The red earth has a big spike and grows well. The ear of Red Globe is very large, loose and oblong, with an average ear weight of 800g and the highest ear weight of 2500g g, and its growth potential is moderate and extremely high, and the fruiting branch rate is above 70%. It usually bears fruit in the second year after planting.

The quality is excellent and the food is delicious. The fruit of this variety is round to nearly conical, and the grain weight is 1 1- 13g, with a maximum of 22g. The peel is bright red to purplish red, and the flesh is hard and crisp. Slice with a knife without dripping juice. The content of soluble solids is as high as 17%-20%, with unique fragrance and no fruit cracking.

3. The fruit handle has strong tensile force and good storage and transportation resistance. The fruit stalk is long, the fruit grains are planted firmly, and the tensile strength is strong. Holding a fruit can lift the whole grape. After the fruit is ripe, it can be stored for 1-2 months, and stored at low temperature with preservative until May of the following year, with no loss of flavor.

4. Good market and high economic benefits. The American red grape market sells well and is well received by consumers. The general price is 20-30 yuan per kilogram.

Two, in the cultivation management should do the following aspects:

1. Reasonable planting, choose loam or sandy loam with high terrain, smooth irrigation and drainage, and deep soil layer, which is suitable for spring sowing in the south. Prune the root system before planting, stimulate the wound to take root, disinfect the branches with sulfur mixture, pour root water thoroughly after planting, spread plastic film to promote heat preservation, and take root and sprout early.

2. Pruning: Red Globe grape has strong growth potential, obvious top advantage, young trees grow, and new shoots mature late, so it is necessary to pay attention to the balance of tree potential and promote growth. Because the rate of fruiting branches of grapes is moderate, the pruning of fruiting trees is mainly in the middle branches, and more fruiting mother branches should be reserved appropriately, and attention should be paid to selecting branches with full bud eyes and full branches.

3. Flower and fruit management: the red picking ears are arranged closely, and the squeezed parts of the fruit cannot be colored normally. There are only 65,438+0 ears left in each new bearing branch. When the size of young fruit is clear, the whole fruit is pruned, and the fruits with poor fertilization, incorrect fruit shape and yellow color are removed, leaving the fruits with uniform fruit shape and bright green color.

4. Use fertilizer and water scientifically. Don't be afraid of drought and waterlogging during the young seedling period of Red Globe grape, and fully irrigate it after planting. At the beginning of the seedling stage, manure and clear water should be poured, and thin fertilizer should be applied frequently every 5-7 days, and its concentration will gradually increase with the growth of plants to promote the rapid growth of seedlings.
