Kronson Grape Cultivation Technology

Crimson is a nuclear-free, alias Krison, non-nuclear, red, non-nuclear, non-nuclear, and red. The United States was nurtured in 1983 and introduced into my field in 1998. Thanks to its beautiful appearance, good quality, good transport and storage, the market for fruit is very good, and the price is significantly higher than that of red grapes.

Ears of medium size, with shoulders, cones, average weight of 500 grams per spike, maximum ear weight of 1500 grams. The fruit is bright red, purple when fully ripe, thick white cream, average weight of 4 grams, ginseng and gene application can increase fruit to 6-8 grams. The flesh is light yellow, translucent and fleshy. The flesh is hard, and the skin is of medium thickness. It is not easy to separate from the flesh and the flavour is sweet. The soluble solids content can reach over 19% and the ratio of sugar to acid is greater than 20:1. The fruit is not cracked before harvesting, and the quality is excellent without falling after harvesting.

Tender slightly reddish green, shiny, no fluff. Young leaves are purplish red with green leaves. Mature leaves medium-sized, green, deeply dissected, serrate moderately sharp, petiole long, petiole concavely rounded or elliptic.

Cultivation Techniques:

1. Build a garden

Creeling grapes are growing prosperously, and they are best cultivated on scaffolding or on “high and wide vertical” postures. The row spacing is 2-4 meters, the plant spacing is 0.5-1 meters, and 250-300 acres are planted.

Soils should be deep, fertile, loose sandy loam or light loam, PH value 6-7.5, well-drained flat or sloping land, and a frost-free period of more than 170 days.

When planting in spring should be carried out at a subterranean soil temperature of 7-10 degrees, planting depth can generally be planted in depth within the nursery. When the seedlings are planted, the root system must be stretched to the surrounding area, fill the roots with fine soil, shake gently, raise the seedlings upwards along the frame, and then fill the soil with 20 cm. The entire planting groove surface will be repaired and smoothed. Water irrigation. After 3 days, planting a ditch to cover the mulching film, and breaking the film on the ground part of the seedlings, then using a fine soil to gently cover the seedlings with the seedlings on the membrane to form a bread-like shape to facilitate water conservation and promote germination. Improve the survival rate of seedlings.

2. Management after the planting

The germination time can be carried out when the quality of the bud can be discriminated, leaving strong and weak, leaving 1-2 strong buds for each plant, and the rest will be erased.

Interval between topping, Krisen grape grows vigorously, the planting seedlings can grow to more than 2 meters, according to conventional management not only waste resources, but also easy to germinate winter buds, affecting the output of the second year. If it is allowed to grow naturally, the underlying buds and eyes are not substantial, and there is basically no inflorescence in the second year after winter shearing. The correct approach is to pick up the heart for the first time when the new one grows to 60-70 centimeters. Only the top vices and the vices who need to make the result are left. The rest are erased. After a slight interval of 40-50 centimeters after repeated topping, the final control to 1.5-2 meters. In this winter, no matter where it is cut, it can have an inflorescence.

3. Management after the second year

To control production, the output is strictly controlled at about 1,500 kilograms. Too many fruits are small, and the color is poor, which affects the value of the commodity. Too low not only does not increase the profit, but also can make the branches too long and cause a vicious cycle.

Continue to take care of each other. The details are similar to those in the first year.

Keeping the renewed branches, Krissen’s grape grows prosperously, resulting in a high part of the result, which tends to bring the result up. Mature trees need to keep renewed branches each year to balance the tree potential.
