The latest course on planting techniques and methods of Golden finger Grape

Golden finger grape is an European and American hybrid, with large ear, long conical shape, moderate tightness, average ear weight of 750g, maximum ear weight of 1500 g, strange and beautiful shape of fruit, mature in late July, strong resistance, adaptability and cold resistance. It is the only European and American hybrid with high sugar content and early maturity. It is unique in the huge grape family. Let's take a look at the planting techniques of Golden finger grape.

Planting benefit of Golden finger Grape

Golden finger grape has beautiful appearance, high sugar content and good flavor, which is in line with the concept of high-end consumption, so it can be sold at a very high price. In 2007, Golden finger grapes sold 50 yuan per jin, calculated according to 3000 jin per mu, an astonishing output value of 150000 yuan per mu. Even in economically backward areas, the price is several times that of Jufeng grape. Calculated according to 5 yuan per jin, the output value per mu can reach 15000 yuan, and the benefit is very considerable.

Golden finger grape frame construction

1. Frame selection: Golden finger grape has strong growth potential and easy flower formation, so it is suitable for any cultivation mode. In recent years, Shandong fresh Grape Research Institute has done a variety of tests, such as small scaffolding, greenhouse frame, single-arm stand, double-arm frame, T-frame, double-cross V-frame, Y-frame and so on, and the effect is the best compared with Y-frame.

2. Frame design: the height of the column is 2.3 to 2.4 meters, the underground planting is 0.5 to 0.6 meters, and the aboveground part is 1.8 meters. Tie three crossbars 0.5 m, 0.8 m and 1 m long at 0.7 m, 1.2 m and 1.7 m above ground respectively, requiring equal length at both ends, and pull an iron wire at each end of the crossbar, and at the same time pull an iron wire on each side of the pillar at 0.5 m above ground. In this way, there are 4 iron wires on each side of the column to complete the frame type.

3. Frame planting: the soil can be prepared for planting after thawing in early spring, the general land is irrigated once, if saline-alkali land is irrigated twice. When planting, the seedlings should not be buried too deep in the soil, and the top of the seedlings should be exposed to the ground 5ml / 10cm. Pour a small amount of water after planting, then cover the ground part of the grape seedlings with plastic film, dig out the aboveground part of the grape seedlings, and press the plastic film with a small amount of soil so as not to let the wind blow. The planting density is 2.5 to 2.8 meters in large row spacing, 0.2 meters in small row spacing, 1 meter in plant spacing, and 400 plants per mu.

Planting technique of Golden finger Grape

1. Soil management: Golden finger grape strengthens soil management during cultivation and management, often ploughing and weeding, timely deep ploughing, and cooperating with other management, a good harvest will be obtained. the main methods are deep ploughing, intercropping, mulching, grass growing and other measures.

2. Fertilizer management: the root system of Golden finger grape is well developed, the growth potential is prosperous, and the new shoots are upright. Fertilization, like other varieties, requires not only elements such as N, P, K and Ca, but also trace elements such as Zn, B and Mn. The period of fertilization should be closely combined with the growth and development stage of grape.

3. Water management: Golden finger grape has stronger drought resistance than apple, pear, peach and other fruit trees, and many dryland vineyards can obtain high yield. Although drought resistance is strong, timely irrigation can ensure high yield and high quality of fruit. At the same time, the irrigation of vineyard should also take into account the physiological characteristics of grape growth and development.

4. Reasonable load: too high grape yield not only affects the quality and postpones ripening, but also makes the tree senescence prematurely. The tree load must be strictly controlled in production. Under normal management conditions, the strong fruiting branch can leave 1 ear fruit, the middle branch only 1 ear fruit, and the weak branch does not leave fruit.

5. Grape bagging: bagging is one of the best ways to obtain bright, high-quality and pollution-free fruits. It has become an indispensable important link in the production of high-grade grapes. Grape bagging can effectively reduce the harm of fruit diseases and insect pests, reduce the number of spraying, reduce pesticide residues, improve fruit quality and increase commodity value.

6. timely harvest: can golden finger grapes be picked and listed one after another 20 days after expansion and softening, but if you want to reflect the strong honey flavor of golden finger grapes, it is best to let them be fully ripe before harvesting. The bagged Golden finger grapes of Shandong Food Grape Research Institute generally begin to be harvested around September 1 every year and end in mid-late October, during which the grapes are fully ripe and can be used as high-grade gifts.
