Victoria Viticulture Management Technology

Victoria Grapes was introduced from China by Romanian Changli Fruit Tree Institute from Romania to Europe and Asia. After years of cultivation, it has shown the advantages of large grain, beautiful color, superior quality, early fruit, high yield, strong adaptability, no fruit cracking, no threshing, etc. The comprehensive traits are excellent.
Tender slightly yellow-green, with sparse hairs, new slightly half upright, green. Young leaves yellowish-green, blushing at the edge, shiny, thin villi on the back of the leaves, moderately large, yellow-green leaves, medium-thick leaves, suborbicular, leaf margin slightly revolute; leaves 3--5-lobed, striately engraved, pale Undercut deep inscribed; serrated small and blunt; petiole yellow-green, petiole and main vein equal length; petiole opening wide arched. One-year-old mature branches yellow-brown, medium-length internodes. Diploid, bisexual flowers.
Ears conical or cylindrical, average ear weight 730 grams, maximum 1950 grams. The fruit is medium and compact, with large fruit, long oval, beautiful and attractive, with an average grain weight of 9.5 g, an average diameter of 2.31 cm, a longitudinal diameter of 3.3 cm, and a maximum grain weight of 16 g. Peel is yellow-green, medium in thickness, hard and crispy in flesh, sweet and refreshing, more than 17% sugar, excellent in quality.
Moderate growth, the result coefficient is high. The second year can reach more than 800 kg per mu. In Guilin, Guangxi, sprouted in early April, blossomed in early May, and matured in late-June.
Cultivation Techniques:
1, planting density Victoria grapes grow moderately, flowers become easy. In order to increase the output of the second year and increase the planting efficiency, it is advisable to cultivate the fence and increase planting density appropriately. In particular, encrypt the spacing between the plants. If the row spacing is 2.5 meters, the plant spacing is 1.2--1.5 meters and the acres are planted around 176-220. Planting 3-4 new shoots per plant in the current year, according to the second year result rate of 90%, each strain can result in 8-12 ear, producing about 2 kg, so that the result can be 1500 kg per acre. A year of planting and two years of high yield.
2, fertilizer and water management to get high yields, must be appropriate to increase the amount of fertilizer. Before sprouting, apply 100 g of compound fertilizer or diamine phosphate, apply 200 g of compound fertilizer to the fruit set, and apply 200 g of urea to the young fruit to facilitate rapid fruit enlargement. Fertilizer combined with watering. During the growth phase, the spray was sprayed on the leaves. The leaves were sprayed with 1500 times too much fertilizer and potassium fertilizer for 3- or 4 times; the fruit was sprayed with 2% potassium dihydrogen phosphate every 10 days before ripening, and sprayed three times in total to increase fruit sugar content. the amount. After the fruit is harvested, each year, the ditch is planted on the side of the planting ditch, and 5,000 kg of organic manure is applied.
3, pruning Victoria Victorian hedgerows cultivation mainly in natural fan shape pruning. When winter cut, you can use medium and short slightly combined pruning. Pay attention to reasonably update the vines, regulate the vegetative growth and the amount of results, and prevent the resulting parts from moving up.
4, flowering Victoria Victoria knot strength, inflorescence, high fruit setting rate, should be removed before flowering part of the inflorescence. In general, 1-2 spikes are kept in thick branches, and 1 spike is left in the mean tree branches. The thin and weak branches are used only for regenerating branches, leaving no spikes. And sparse the deputy panicle, remove about 1/4 of the ear tips. Leave 5-6 leaves topping in the inflorescence 1 week before flowering.
5, bagging bagging can reduce pests and diseases, increase the value of goods. Because of its yellow-green color, Victoria grapes do not need to be bagged prior to maturation and are sold with bags for better results.
