Why are the grapes rooting here? How do you stay when the vine sprouts from the old roots?

The root system of the grape is made up of the root trunk, root neck, lateral roots, fine roots and root hairs. The root stem mainly plays the role of fixing the plant, and at the same time has the function of storing nutrients and transporting water and nutrients. Lateral roots and fine roots transport the absorbed minerals to the root stem through water, and convert the inorganic nitrogen, inorganic phosphorus and other substances absorbed in the soil into organic nitrides and organic phosphorus. The absorption of grape roots is mainly carried out by the young roots that have just emerged, which are fleshy, white or yellowish in the early stages of formation.

The white part of the young root has root hairs, which use root pressure, osmotic pressure and transpiration on the ground to absorb water and nutrients to supply the needs of all parts of the plant. As the surface of the young roots gradually becomes corked, the epidermis turns brown, and the absorption zone becomes a grooming part. Young roots also have a symbiotic effect with the mycelium of soil fungi, producing endomycorrhizae and ectomycorrhizae, which have a strong absorption function.

When the old and new root systems alternate, the absorption of water and nutrients mainly depends on mycorrhizae.

This is aerial rooting.

1. Aerial roots refer to roots that grow from the ground trunk in the air. Generally, when the humidity is high, the grapes are prone to aerial roots when they grow vigorously. In general, aerial rooting does not adversely affect the growth of grapes.

2. Not only will the vines take root when they touch the wet soil, but even in the humid air, many aerial roots will grow on the old vines. It's just that different grape varieties have different degrees of rooting, and general cultivars are easier to root, which is also a prerequisite for cuttings propagation and strip propagation in viticulture.

1. Waterlogging leads to root rot.

Under the condition that the grapes are in excessively wet soil, the root system lacks infiltration and oxygen, resulting in root rot. Therefore, for the flooded vineyards, ditches should be opened in time to remove the water in the orchards, and if possible, drainage and irrigation facilities can be used to drain the water, so as to prevent the orchards from being flooded for too long.

Two: Excessive results lead to rotten roots.

In case of excessive fruiting, resulting in vines.

The tree has reduced nutrients and rots roots. Young leaves should be removed in time, tender and slight, and the secondary branches with vigorous growth should be removed, so as to reduce nutrient clusters or consumption, and promote the recovery of the tree.

Three: irrigation at high temperature causes root rot.

During the irrigation of the vines, if the vine is dry, the irrigation at high temperatures will cause the temperature difference to be too large and the roots will rot. Therefore, irrigation should be carried out at noon or around 4 p.m.

Four: Drought can also lead to root rot in grapes.

In some vineyards, the plants next to the canal or in the low-lying area grow normally, while the grapes in other fields will generally rot roots, indicating that this is the root cause of grape root rot caused by long-term drought due to root weakness or death, so proper irrigation is the main measure to solve root rot Grape root rot control.

For the more moist soil should be sprayed with lime on the ground, soil disinfection, to the soil is dry, the soil is more compacted garden to loosen the soil, increase air permeability, in order to prevent root deficiency caused by root rot, should also apply phosphorus and potassium fertilizer, root preservative to promote the root to promote new, improve disease resistance.

Generally, it is easy to cause insect pests after waterlogging, so it should be prevented and controlled in time and treated with pesticides.

Give it plenty of water and cut off some old branches for him to sprout.

Viticulture management:

1. Select suitable varieties for planting.

1. When planting grapes, you should choose varieties according to your location, and the varieties that are often seen by hand are giant roses, Clensen, beauty fingers, etc., if you plant grapes in the black soil of the northern region, then you can choose ordinary varieties to plant, because the soil nutrients in the north are relatively high.

2. During the period, the grapes should be watered frequently, and the grapes should not be drought, if the grapes lack water, it will lead to the thin fruit of the grapes, and the soil in the southern region needs to be planted with strong vitality varieties, because most of the soil in the south is acidic.

2. Strengthen water and fertilizer management.

1. After grape planting, the management of water and fertilizer should be strengthened, if the soil is dry and lack of water will cause the fruit of grapes to be thin, watering and fertilization are conducive to promoting the healthy growth of grapes, a small amount of fertilizer should be carried out many times when fertilizing grapes, and fertilizer can be applied once when the grapes have just grown seedlings, and fertilization can be used to soluble fertilizer for emerald water, and timely supplement the nutrients required for grape growth, so that the main stem of grapes can develop more robustly.

2. After the grapes bloom, fertilize the grapes again, fertilization at this stage can promote the grape fruit to become more shiny, so as to improve the quality and yield of the grapes, while fertilizing the grapes, it is necessary to properly water the grapes, watering can promote the rapid growth of grapes, and has the effect of diluting fertilizer.

3. Prune branches and leaves properly.

1. Proper pruning of grape branches and leaves is conducive to brightening the yield of potatoes and grapes, if the branches and leaves are very lush, it will cause the main trunk of grapes to not absorb sunlight.

2. Therefore, at this stage, the grape vines should be pruned and branched, and the disease-free branches and leaves of the main trunk of the grapes can be retained, and the branches and leaves with diseased branches and leaves and excess branches should be cut off, and the wounds of the branches and leaves should be smeared after pruning to avoid the invasion of viruses.

Fourth, build a climbing frame.

If there are no climbing objects around the vine, it is not conducive to the survival of the vine, so it is necessary to build a climbing frame around the vine and wrap the vine branches around the climbing frame.

5. Spraying agents.

In the later stage, when the flowers of grapes have grown, they absorb more nutrients, and over-dense growth will lead to insufficient nutrients and poor fruit quality, so it is necessary to cut off half of the over-dense parts of grape flowers, and then spray pesticides on grapes to prevent the occurrence of pests and diseases.

Grapes need to absorb water and mineral nutrients from the soil during the year, and the importance of roots is self-evident. In recent years, the problem of grape root uplift has become more and more serious, and the reasons for the grape to keep up with the rise are:

1. The groundwater level of the vineyard is high or the drainage is poor.

Therefore, such orchards are prone to suffocation of grape roots, which forces the grape roots to grow to the surface, causing the grape roots to float.

2. The fertilization method is not scientific.

Grape roots are water-oriented, such as spreading fertilizer on the ground for a long time, without enough water to dissolve the fertilizer and make it penetrate downward, which can easily cause the grape roots to float.

3. The choice of fertilizer is unreasonable.

Grapes prefer loose and deep soils, such as long-term partial application of chemical fertilizers, ignoring the application of organic fertilizers, which can easily lead to soil compaction and poor air permeability, thus forcing the grape roots to float.

Font grapes belong to the Vitis vinifera. The fruit is spherical or oval in shape, up to 2 cm in diameter. It blooms in April-May every year, while its fruiting period is August-September.

The lowest branch is more developed. It is an ancient tree species that can prevent blood clots, detoxify and prevent cancer. Grapes are widely distributed in China, Yinchuan in Ningxia, Wuwei in Gansu, Turpan in Xinjiang, Shihezi in Xinjiang, Maitreya in Yunnan, and the Yellow River.

Grape origin. Grapes** were generally stable. The cheapest grapes are the Jufeng grapes from Beizhen, Jinzhou City, Liaoning Province. The currency price bureau is cautious.

Grape origin.

Grapes are generally grown in some warmer regions, mainly between 23-52 degrees north latitude in China. The grape producing areas in Northwest China are centered on Xinjiang, including Shaanxi and Gansu, and Turpan is a concentrated grape producing area. Grape growth characteristics: Grapes need to be grown at the right temperature.

The minimum temperature they can tolerate is between 12 and 15 degrees Celsius, and the temperature is kept around 20 degrees Celsius during flowering.

Where the grapes are grown.

Grapes are generally grown in the summer. During maintenance, the temperature should be kept between 12-15 degrees, and the minimum temperature should not be lower than 10-13 degrees. During flowering, the temperature should be kept at 20 degrees. Always have plenty of sunlight and a good ventilation environment.

Grapes are grown in**.

Grapes are native to Western Asia and are widely distributed in the world. The main production areas in China are Xiaoxian County in Anhui, Zhangjiakou, Xuanhua and Changli in Hebei, Turpan and Hotan in Xinjiang, Dalian, Xiongyue and Shenyang in Liaoning, Yantai in Shandong, Quanmin and Lumiao in Yifeng in Henan.

Grape growing environment and conditions.

1.Temperature: Grapes are not cold-tolerant.

The minimum temperature required for growth is about 12 to 15 degrees, 20 degrees for flowering and 20 to 30 degrees for fruit development. If there is a large temperature difference between day and night, the quality of the fruit will also improve. 2.

Moisture: Grapes need a lot of moisture during the growing season. Strict control of soil moisture is a prerequisite for growing good grapes.

Sunlight: Grapes like a sunny environment, which can carry out photosynthesis and accumulate more nutrients, which will make the appearance of the grapes more beautiful and shiny, and the sugar content of the fruit will also be improved, and the quality will be superior. 4.

Soil: Although grapes are well adapted to the soil, they grow best in loam and fine sandy loam soils with good drainage, fertilizer and water retention, and loam soils are best between sandy and clay. Manuscript acres.

Grape growth process:

1. At the end of March and the beginning of April, the alliance buds began. The young leaves of goose yellow have a layer of small white fine hairs on them.

2. Flowering and pollination around June. Clusters of creamy yellow buds bloom and then flowers, which produce very small grapes when they fall.

3. In July, the leaves of the grapes grow particularly vigorously, and the bunches of green grapes are as big as fingernails, hard and hard, and the grapes at this time are particularly sour.

At the end of the month and the beginning of October, the grapes are ready to be harvested without increasing sugar content.
