Why is it so difficult to grow drunken grapes, and what do you need to pay attention to? How difficu

Attention needs to be paid to these:

First, choose the type of potassium fertilizer: spray potassium fertilizer outside the grape root, it is advisable to choose potassium dihydrogen phosphate, potassium sulfate, high-quality grass ash leaching solution and other fast-acting potassium fertilizer, should not use potassium chloride, because chlorine ion permeability is strong, a large amount of into the plant can cause poison, and can reduce the sugar content of the fruit, reduce the quality of the fruit.

At the same time of spraying potassium fertilizer, it is necessary to cooperate with the application of nitrogen and phosphorus to ensure the normal effect of potassium fertilizer.

3. Spraying concentration: potassium dihydrogen phosphate is better with o, 5 is better, potassium sulfate is better, grass ash leaching solution is suitable at 3 5, and the concentration should not be too large to avoid fertilizer damage.

5. Add adhesive: add an appropriate amount of neutral laundry detergent to the fertilizer as an adhesive to prolong the time that the fertilizer stays on the foliar surface as much as possible, ensure the full absorption of the leaves, and improve the fertilizer efficiency.

6. Pay attention to spraying skills: spray potassium fertilizer on the outside of grape roots, spray wine evenly on both sides of the leaves, and spray 60 kg of fertilizer per mu.

7. Other ways of potassium application: After grape fruit picking, an appropriate amount of potassium fertilizer is applied in combination with autumn basal fertilizer, accounting for 30% to 35% of the total amount of potassium fertilizer applied throughout the year.

Botanical traits:

The shoots are green and have few hairs. The young leaves are green, the leaf surface is slightly shiny, and the lower surface of the leaf is hairy. Adult leaves are extra-large, heart-shaped, 3-5-lobed, deeply lobed, green, rough, with vesicular convex bulges, mostly dorsal leaf hairs, petioles sagittal shaped, petioles long, purple.

Fruit traits: The fruit spike is extra-large, with an average spike weight of 800 grams and a maximum of 1800 grams, which is conical and compact. The fruit is extra-large, the average grain weight grams, the maximum grain weight grams, the fruit grains are obovate, the peel is golden yellow when fully ripe, the maturity is consistent, the size is neat, the navel is obvious, the fruit powder is more, the peel is medium thick, and the peel and the pulp are easy to separate.

Growth Fruiting Habits:

The plant grows vigorously, the germination rate of bud eyes, the rate of fruiting branches, the average inflorescence of each fruiting branch, and the strength of the secondary knot. It has strong resistance to fungal diseases such as downy mildew and white rot.

Cultivation points: This variety is suitable for trellis or hedge cultivation, medium and short tip pruning. In the young tree stage, the tree should be strong and not overgrown, and promote the balance between vegetative growth and reproductive growth.

After fruiting, it is necessary to keep sufficient fertilizer and water, especially to pay attention to organic fertilizer in autumn, appropriate amount of nitrogen fertilizer, and more phosphorus fertilizer and potassium fertilizer.

The steam temperature should not exceed 28 degrees.

European and American hybrids. Liaoning Academy of Agricultural Sciences used Shenyang Rose (7601) as the female parent and Jufeng as the male parent to cross and bred a tetraploid fresh food variety. In 1997, it passed the variety approval.

Tender shoots, young leaves green, hairy; Branches stout, light brown when mature; Adult leaves are medium-large, heart-shaped, 3 5-lobed, shallowly notched, and the dorsal hairs of the leaves are numerous. The spikes are medium-large, conical-shaped, and weigh 400 500 g. The fruit is large, obovate, yellow-green, with an average grain weight of 7 8g, the skin is medium thick, the flesh is slightly soft, juicy, sweet, and has a strong jasmine fragrance.

When fully mature, the soluble solids content is 16% to 20%. Zuijinxiang is a new variety of tetraploid table grape in Europe and the United States, which is easy to be cultivated without seeds, which has the characteristics of high quality, disease resistance, high yield and stable yield, and has strong resistance to fungal diseases such as downy mildew and white rot, and is more suitable for the high temperature and rainy climate characteristics of the growing season in southern China.

The middle stage is the period when the fruit grows and swells, and it is very much in need of nutrients, and it is necessary to avoid fruit dropping

Avoid overpowering the vines, which will compete with the ears for nutrients and aggravate fruit drop.

Foliar sprays of amino acid calcium boron foliar fertilizer can preserve the fruit, and the element boron calcium can make the fruit set more stable and reduce fruit drop.

Microbial fertilizer with nutrients can be applied on the ground to maintain the root system and make the root system more able to absorb nutrients. It can also help the fertilizer in the soil to be more easily absorbed by the roots. The nutrients for the growth of the grapes are sufficient, and the fruit drop is naturally less.
