Grape planting information is comprehensive, and there must be more points. Thank you

Plastic pruning: When planting the red grapes of the year, when the new shoots grow to 25 cm, leave 2 branches with good growth and remove the other branches. When the new shoots grow to 40 cm, they are tied to the temporary wooden sticks, and the secondary shoots are left with 1-2 leaves repeatedly topped, and when the autumn is on, the extended branches are topped, and the winter pruning is cut according to the maturity of 1-1 50 meters, and the wound is smeared with a callus antiseptic film after pruning, so that the wound heals quickly.

Fertilizer and water management: before germination in the following year, with irrigation bud water, apply 20 kg of urea per mu (germination fertilizer); Inflorescence appears to be irrigated 1-2 times before flowering; In the swelling stage of young fruits, 20 kg of diamine (flowering fertilizer) per mu was applied at the same time, and 25 kg of ternary compound fertilizer per mu was applied at the hard core stage, and irrigated at the same time; From mid-August to before fruit harvesting, foliar spraying of 0 30 potassium dihydrogen phosphate 3--4 times (color fertilizer) to promote the ripening of fruits and new shoots, and to control the water of the whole garden, spray Kao No. 3 after 20-30 cm of new shoots, which can transform plant vegetative growth into reproductive nutrition, inhibit the crazy growth of main shoots, promote flower bud differentiation, more flowering, improve pollen fertilization quality, more flowering, more fruit setting, prevent fruit dropping, and promote development.

Flower and fruit management: early thinning of inflorescences, extension of vines can retain 2-3 fruit spikes, and the rest of the fruiting branches leave single spikes. At the same time, the shoulder and spike tip are removed.

Spray 0 30 borax plus 0 30 urea before flowering. Thin out the small fruits, deformed grains and over-dense fruits with poor fertilization, remove the lower part of the fruit spike 1 3--1 4, about 3 weeks after flowering, spray Zhuangguo Tiling, thicken the fruit pedicle, and improve the amount of nutrient delivery. Prevent falling flowers, falling fruits, cracked fruits, stiff fruits, and deformed fruits, so that the fruit is beautiful in color and beautiful in shape.

Grape is a grape variety, just look at the knowledge of viticulture.

The situation you are talking about is an indication that the grapes are overwatered, so much so that they burst naturally when they are almost ripe.

There are too many rainy days, too much moisture leads to explosion, and it may also be caused by a large temperature difference between day and night, thermal expansion and contraction.

Grape cultivation technique.

Flower and fruit management. Early thinning of the inflorescence, the extension of the vine can retain 2-3 fruit spikes, and the rest of the fruiting branches leave a single spike fruit. At the same time, the shoulder and spike tip are removed.

Before flowering, after flowering, at the young fruit stage and at the fruit expansion stage, the melon and fruit were sprayed once to make the nutrient number duct of the fruit tree thicker, increase the amount of nutrient transport, strengthen the flowers and fruits, and improve the fruit expansion vitality. Remove the small grains, deformed grains and over-dense grains with poor fertilization, remove the lower part of the fruit ear 1 3--1 4, and about 3 weeks after flowering, dip the fruit ear or spray the fruit ear with grape bulking agent and methyl tobuzin (or antibacterial). When the bulking agent and fungicide have been used, the fruit ear should be bagged in time, and the bag should be removed about 20 days before harvesting, and the fruit ear should be rotated to achieve uniform color.

Fertilizer and water management. After the fruit is harvested every year, 3000 kg of organic fertilizer plus base fertilizer plus superphosphate is applied immediately per mu. Grapes should be poured with winter water before they are taken off the shelf.

Before germination in the following year, with irrigation water, 20 kg of urea per mu (germination fertilizer) was applied; Inflorescence appears to be irrigated 1-2 times before flowering; In the swelling stage of young fruits, 20 kg of diamine (flowering fertilizer) per mu was applied at the same time, and 25 kg of ternary compound fertilizer per mu was applied at the hard core stage, and irrigated at the same time; From mid-August to before fruit harvest, foliar sprays of 0 30 potassium dihydrogen phosphate 3--4 times (color boosting fertilizer) were applied to promote the ripening of fruits and new shoots, and to control water throughout the garden.

Pest control Before the grapes are taken off the shelf, spray 3-5 degrees of baumerite sulfur mixture plus 0 50 sodium pentachlorophenol plus new high-fat film mixture to disinfect the whole garden. From June to August every year, the prevention and control of downy mildew and powdery mildew is the mainstay, especially in the case of high plant density, high temperature and high humidity, the plants should be observed at any time and prevented as soon as possible.

Grape seeds can be planted, but the grapes that grow up are not always of satisfactory quality.

The method of planting grape seedlings with grape seeds is to wash the leftover grape seeds before New Year's Day, sow them in pots, sow them to a depth of about 3-5 cm, and water them thoroughly and put them outside. After that, water it every 20 days or so to prevent the potting soil from drying out and let it survive the cold winter outdoors, so as to help it complete its natural dormancy.

In early March, you will be watered once every 7-10 days, and in early to mid-April, your grapes will be ready to sprout. Strengthen soil, fertilizer and water management and pest control, it can grow to about 50 cm tall in the current year, and it can be transplanted in the spring of the next year.

Genetics tells us that traits in hybrid generations will mutate (sometimes for the better, sometimes for the worse). The same is true for grape seeds, which produce grapes that produce grapes with a certain degree of variation in economic traits compared to those of the mother tree. Therefore, in production, the propagation of grape seedlings is mainly carried out by cuttings, in addition to the strip method, grafting method and other propagation methods.

It can be planted, but what grows is a real seedling, and it does not bear fruit when it grows up, or the fruit is small and the kernel is large, and it is bitter and not delicious!

Key points for the cultivation of grapes.

1) The survival rate of spring planting is higher than that of autumn planting, and the planting period is from early to late February.

The planting density varies according to different shaping methods, and the general row spacing is 1 m to 3 m. Before planting, it is necessary to apply plantar fertilizer, such as: more than 40 kg of rotting organic fertilizer, 3 kg of superphosphate, kg of potassium sulfate, etc.

2) Fertilizer and water managementWhen planting, it is necessary to irrigate enough water to moisten the soil. In case of drought during the growing season, irrigation should be carried out in time. The water in the garden should be removed in time to avoid moldy roots.

From late October to early November, sufficient basal fertilizer should be applied. Top dressing about 8 times a year, that is: when the new shoots are about 20 cm, use human feces or urea for the first top dressing;After that, top dressing is done once every half a month or so.

In the 2-3 times of top dressing after the beginning of August, phosphorus and potassium fertilizers should be added.

3) Before the germination of pest control, spray 1 time of stone sulfur mixture (Baume 3-5 degrees) and sodium pentachlorophenol (200-300 times) mixture to eliminate the source of overwintering. After the first leaf, spray stone sulfide mixture or other fungicide for control. After that, every 10 days or so, spray 1 time.

If pests are found, they should be prevented and controlled in time.

4) Harvest grapes in a timely manner, with large fruits and large ears, so that one ear is ripe, one ear is picked, and it is harvested in batches in a timely manner.
