The best time to water the seedlings and the best time to water the grapes

The best time to water grape seedlings is really in the evening, the root system of grape seedlings is not developed, the temperature is high at noon and the watering is easy to hurt the root system, watering in the evening, moisturizing overnight, so that the grape seedlings get sufficient nutrients, which is conducive to the vigorous growth of seedlings.

The grapes transplanted in winter should be watered, and the water should be replenished in time after planting to avoid drought and wilting. Precautions: water temperature control, pay attention to the water temperature when watering, consistent with the ambient temperature, to prevent frostbite; Suitable temperature, weak cold resistance, suitable temperature 12 15, the lowest ground temperature is 10 13, the north can be transplanted indoors, and the south is recommended to build a wind shield; The best time to do this is when the vines are warm-hearted, and transplanting in April or September can improve survival.

Although the transplanted grapes need to be watered in winter, although they will enter a dormant state, the transplanted seedlings need to be replenished with water in time to prevent the lack of water from causing drought damage to the roots and wilting of the bud spots, which will affect the germination and growth of the shoots after the temperature rises in spring. It is recommended to water once every 10 days or so to keep the soil moist, pay attention to the amount of water when watering, and avoid stagnant water.

1. Water temperature control

The growth of grape vines is inseparable from water, like a slightly humid growth environment, winter transplanted seedlings need to pay attention to the water temperature when watering, to be consistent with the ambient temperature, to prevent frostbite, each time without affecting the soil insulation under the premise, the roots can be watered thoroughly. The water quality is precipitated well water or rainwater, and if tap water is used, it needs to be left in the sun for 2 days until the chlorine gas is completely volatilized.

2. Suitable temperature

In winter, the temperature is very cold, and the grapes are weak in cold tolerance, and transplanting at this time is easy to freeze to death at low temperatures. The suitable growth temperature is at least 12 15, the minimum ground temperature is 10 13, the north can be heated indoors, and control the appropriate temperature, the south is recommended to maintain in the greenhouse, or build a wind shield, do a good job of keeping warm.

3. The best time

The vines are warm-loving, so it is recommended to transplant them in April in the spring or September in the autumn, as the temperature is suitable and the wound heals quickly, helping them to adapt to the new environment faster and resume their growth as soon as possible. In the subsequent fruit growth period, the temperature difference between day and night is large, which is conducive to its development and coloring. The resistance of seedlings decreases after transplanting, and it is necessary to do a good job of preventing pests and diseases.

Before the grapes bud break is an important time for watering, watering this time can play a role in the purpose of germination, can meet the needs of bud breaking. If you do not water in time after unearthing, you may be affected by dry wind, resulting in poor budding and even dry branches.

10 days before flowering and 10 days after the flowers fall, these two periods need to be watered thoroughly. Before flowering, new shoots and inflorescences grow rapidly, and transpiration is very strong, and the water requirement is relatively large. After the flowering, the new shoots have gradually thickened and grown, the leaves can also increase rapidly, and the root absorption is relatively vigorous, which is a critical period of water and fertilizer.

The peak of growth is when the berries begin to color, when the growth is rapid, the inflorescence develops rapidly, and sufficient fertilizer and water supply is required, otherwise the yield and quality will be affected.

During the ripening period of berries, if the moisture in the soil is appropriate, the fruit can grow and develop well, the yield can also be high, and the sugar content will be high. If the water supply is difficult, the development of the berries will be problematic, so it is necessary to water in moderation, but not excessively, otherwise the sugar content will also decrease.

1. Watering during germination. The effect of watering grapes before excavation to germination and branch pulling, and continuous irrigation of germination water after the application of germination fertilizer is better. 2. Irrigation and watering before and after the flowering period.

Irrigate about 10 days before and after flowering, and water once each. 3. Watering during the berry expansion period. When the berries grow to the size of soybean grains, the new shoots are also growing and closing Sun Sheng, at this time, the temperature is rising, the water evaporation of the leaves is getting larger and larger, and nutrients and water are urgently needed, and each is irrigated with water.

3. Watering during the berry expansion period. When the berries grow to the size of soybeans, the new shoots are also growing vigorously, and the temperature is rising, and the amount of leaf water is getting bigger and bigger, and nutrients and water are urgently needed. 4. Watering after fertilization in autumn.

After the fruit is harvested, it is necessary to prepare for autumn fertilization, and at this time, watering in combination with basal fertilizer can promote the accumulation of nutrients in the tree, which plays an important role in the growth and fruiting of the next year.

Grape seedlings refer to the seedling period of grapes, when watering grape seedlings, you need to follow the principle of "seeing dry and wet", pay attention to each watering must be watered thoroughly, spring and autumn can be watered once in 3-5 days, summer needs to be watered twice a day, winter 10-15 days can be watered.

How often should the seedlings be watered.

Grape seedlings refer to the seedling period of grapes, when watering grape seedlings, you need to follow the principle of "see dry and wet", pay attention to each watering must be watered thoroughly, you can use rainwater, river water, tap water for watering, these water contains minerals and certain nutrients, is very suitable for the growth of plants.

1. Watering in spring

The seedlings are poised in the spring, which should be watered about every 3-5 days, because the plants prefer a moist growing environment.

2. Watering in summer

In summer, when the temperature is high and the humidity is low, you can generally water twice a day to keep the soil moist, but not to produce stagnant water.

3. Watering in autumn

The seedlings grow rapidly in autumn, so they are watered about the same frequency as in spring, about once every 3-5 days.

4. Watering in winter

Grape seedlings need to be watered once before winter, because the growth rate of the plants in winter is slow, usually once every 10-15 days.

Precautions for watering grape seedlings.

1. If it is an arid area, it is necessary to water the grape seedlings 15 days before flowering, which is more conducive to the leakage of rotten fruits of the plants.

2. Grape seedlings have a certain drought tolerance, and there is no fixed watering frequency, which needs to be flexibly adjusted according to soil conditions and weather conditions, usually 3-5 days to water a round of leakage.

Grapes cannot be watered during flowering.

Watering will reduce the soil temperature, which can easily lead to flower drop, which will affect the fruiting rate. Usually about 10 days after flowering, water is rehydrated to make the soil slightly wet, which can promote the growth of young fruits. Pay attention to the amount of watering must be controlled, the soil can be slightly wet, and there should be no water accumulation.

Grapes consume more nutrients during flowering than clumps, and in order to meet the needs of flowering and fruiting, they should be topdressed both before and after flowering. It is advisable to spray boric acid before flowering to increase its fruit set. In addition, it is necessary to harvest the topping in time to reduce nutrient consumption.

Grapes are sensitive to temperature during flowering and prefer warm conditions. It is best to control the temperature at about 28 degrees during the day and between 16-18 degrees at night, so that the environment can promote better flowering. Note that if it is cultivated in a greenhouse, it is necessary to ventilate the pin beams frequently, and do not provide an airtight environment.

Grapes should be thinned 10 days before flowering, to ensure that there are more than two inflorescences on each fruit branch, and the weak inflorescences should be cut off, leaving only the good inflorescences.

Precautions for viticulture

During the planting of the vines, the vines need to be watered every week to keep the soil moist. The soil requirements of the vine are not high, but in order for the vine to grow and develop normally, it is best to choose a sandy loam or light loam soil with a loose soil, permeability, drainage and good fertility with a weak acidic to slightly alkaline bulk density.

The vines are usually planted in March-April, but also in September-October. In the spring, you need to prune properly, and you only need to leave two stronger buds at the beginning.

After the grapes have budded, when 4 or 5 new leaves appear in the new shoots, top dressing is carried out, human manure and urea can be used before June, nitrogen, phosphorus and potassium compound fertilizers are used in July and August, and fertilization is applied when the weather conditions are good.

Newly planted grape seedlings are usually watered once when planting, so that the soil is kept moist and packed, and then wait for 5-7 days to water again, do not water too much, because for the newly planted grape seedlings, the root system does not recover growth, too much watering can not adapt, there will be water and rotten roots. When the grape seedlings adapt to the new environment, they can be watered normally, maintain a slight humidity, and can be watered frequently in summer, but there should be no stagnant water, and a certain humidity must be ensured.

Knowledge expansion. Soil: Grapes can be grown in most soils, but they grow best in loam and sandy loams, and the soil should not be too heavy and should have good air permeability.

Temperature: During the grape growing period, the temperature should not be too low, the minimum ground temperature should be 10-13, the flowering temperature should be 20, and the fruit growth and expansion temperature should be between 20-30.

Sunlight: During the grape growing period, there should be sufficient sunshine conditions, but the intensity of sunlight should not be too high to avoid sunburn, but it should not be left without light for a long time, which will reduce the fertilization rate.

Grape watering schedule:

1.Irrigation before flowering: Generally carried out 5 to 7 days before flowering, this irrigation is called pre-flowering water or flowering water. This is also a critical watering period to create a favourable moisture condition for the grapes to blossom and set fruit and to promote the growth of new shoots.

2.Water control during flowering: During the 10 to 15 days from the first flowering to the last flowering, the vineyard should stop supplying water, otherwise it will be affected by irrigationA large number of flowers and fruits are dropped, large and small grains appear, and even the yield is seriously reduced.

3.Irrigation during berry expansion period: from 10 days after flowering to before fruit coloring, the fruit expands rapidly, the branches and leaves are vigorous, the outside temperature is high, the leaf transpiration loses a lot of water, and the plant needs to consume a lot of water, and it should generally be irrigated once every 10 15 days.

Grape Overview:

Among the many fruit trees, grapes are more resistant to drought than apples, pears, peaches and other fruit trees. Many dryland vineyards are able to achieve high yields. Although drought resistance is strong, timely irrigation can ensure high yield and high quality of fruit.

When the soil moisture content is 60% to 70%, the root system and new shoots grow best. If the water holding capacity exceeds 80%, the soil is poorly aerated and the ground temperature is not easy to rise, which is not conducive to the absorption and growth of the root system. When the soil moisture holding capacity drops below 35%, the new shoots stop growing.

The long-term moderate drought also helps to control vegetative growth, promote flower bud formation and improve grape quality. Irrigation of the vineyard takes into account the physiological characteristics of the grapes during their growth and development phases.

Several critical periods for watering grapes:

Pre-bud break: Pre-bud break is the first critical period. At this time, the grapes will bud break, the new shoots will grow rapidly, the inflorescences will develop, and the root system will also be in the vigorous activity stage, which is one of the critical periods when the grapes need water. The spring drought in the north, the grapes have been covered with moist soil for a long time, and after the soil is unearthed, they are not watered immediately, and they are susceptible to dry winds, resulting in poor budding and even dry branches.

Flowering period: 10 days before the grapes bloom, which is also a critical watering period. During this period, new shoots and inflorescences grow rapidly, and new roots begin to occur in large numbers in the root system, with strong assimilation, transpiration gradually increases, and more water is required.

During the flowering period of grapes, the water is generally controlled, because watering will reduce the ground temperature, and at the same time, the soil moisture is too high, and the new shoots are too vigorous, which is not conducive to the fertilization of grapes. In sandy areas with strong permeability, such as dry weather, proper watering during flowering can sometimes increase fruit set.

About 10 days after the fall of the grapes, it is the third critical period. During this period, the new shoots grow rapidly, the base begins to lignify, the leaves increase rapidly, the new inflorescence primitives are rapidly formed, a large number of new lateral roots occur in the root system, and the root system absorbs water in the soil to the most vigorous degree, and the first growth peak of berries comes, which is the key period of fertilizer and water demand.

Coloring period: The beginning of berry coloring is the second peak of berry growth, when the berry grows extremely fast and sugar begins to accumulate in the berry. The new shoots grow thicker and begin to lignify, and the inflorescences develop rapidly, and the supply of suitable fertilizer and water at this period can not only improve the yield and quality of the current year, but also have a good effect on the next year's yield.

Ripening period: When berries are ripe, soil moisture is generally sufficient in areas with good irrigation or water retention. Irrigation is required if there is insufficient rainfall, poor soil water retention, or if fertilization is high. The berries are ripe with proper soil moisture, good fruit development, high yield, and high sugar content.

If the moisture is large, the berries can also ripen well, but the sugar content is reduced, the fragrance is reduced, the fruit is easy to crack, and it is not resistant to storage.

Overwintering: When the grapes are buried in the soil to prevent cold, if the soil is dry, it is inconvenient to bury the soil, so a small amount of water is needed before burying the soil. In the arid areas of winter and spring in the north, there is a habit of pouring frozen water in winter.

As for the water deficit index of grape plants, the standard of irrigation can be used according to the growth condition of young shoots, and the sharp and bent tips are normal growth phenomena; If the young shoots are erect and soft, it is a sign of dehydration and should be irrigated immediately. Excerpt from "Red Flag Gardening".

The vines are watered before budbreak, flowering, after flowering, coloring, ripening, and overwintering.

Watering at noon when the temperature is low in winter, the water temperature should not be too low, any time in spring and autumn, watering in the morning or evening in summer, pay attention not to dry and do not water, watering to water thoroughly.
