In spring, it is better to water the grapes in the arch shed and water them in a small way

At the same time, we should also pay attention to the use of medium and micro fertilizers, supplement boron, zinc, silicon and other elements, and make grapes sweeten and increase color, and increase yield.

Summary. The correct way to water the vines.

1. Watering at the germination stage.

When the vines enter the bud break period in spring, it is necessary to replenish water in time, and water the soil after it thaws, and water it thoroughly to keep the soil moist, so that the vines can accelerate their growth.

2. Watering during the growing season.

During the growing season, the grapes should be watered frequently, 2-3 times a week, if the local climate is dry, you can do this, if the rain is more frequent, then you can reduce the watering appropriately, and the soil is slightly wet.

3. Water the fruit set.

The vines bloom in the spring and begin to set fruit after flowering, so keep the soil moist at this time, but not accumulate water, and try to avoid overwatering.

4. Water the fruit.

After fruit set, it is necessary to avoid soil drought, otherwise it is easy to drop fruits, so it is necessary to water the vines regularly, and the vines planted in the greenhouse should always keep the soil slightly moist, and the vines planted in the open field should be watered according to the climatic conditions.

What is the best position to water the vines during the bulging season?

The correct way to water the vines 1, the germination period of the balance of the grapevines watering the spring into the bud stage, at this time to give it timely water, after the soil thaws, to water thoroughly, keep the soil moist, so that the vines can accelerate growth. 2. Watering the grapes during the growing period should be diligent, watering 2-3 times a week, if the local climate is dry, you can water it like this, if the rain is more diligent, then you can appropriately reduce the watering of the limbs, and the soil is slightly wet. 3. Watering fruit setting water Grapevines bloom in spring, and begin to set fruit after flowering, at this time the soil should also be kept moist, but not waterlogged, try to avoid excessive watering.

4. After watering strong fruit water, it is necessary to avoid soil drought, otherwise it is easy to drop fruits, so it is necessary to water the vines regularly, and the grapevines planted in the greenhouse should always maintain the state of soil slightly wet, and the vines planted in the open field should be watered according to the climate conditions.

Have helped you find the fruit of the knot: Hello, normally, grapes need to be watered within 24 hours after using bulking agents. This is because the bulking agent is able to absorb water and make the grapes fuller, but if they are not watered in time after using the bulking agent, it may cause the grapes to lose water, affecting the quality and yield of the fruit.

It is advisable to water within a few small grandchildren after the application of the bulking agent to ensure that the grapes are able to absorb the water adequately. Hope mine is helpful to you<>

If the lack of water is not severe, it is better to water it in the evening.

Watering in the evening, evaporation is small; Watering in the morning, evaporation is large.

Common melons are: pumpkin, winter melon, zucchini, etc.

Zucchini cultivation techniques.

Fertilization of the land. Mainly organic fertilizer, generally Huichangyu applies 2000 kg of decomposed organic fertilizer, 75 kg of cake fertilizer, 40 kg of compound fertilizer, and 80 kg of plant ash per mu. Spread the fertilizer evenly on the ground, turn it 30 cm deep and level the ground.

Ditching and furrowing. Deep furrows and high furrows are used for cultivation, and plastic film is used to cover cultivation. Generally, the furrow is 100 cm wide, the furrow is 20 cm high, and the furrow is 25 to 30 cm wide.

The furrow surface should be leveled again and herbicide sprayed before capping. When covering the film, it must be tightened and flattened, so that the plastic film and the furrow cover are tightly attached, and the surrounding area of the film is compacted with soil. After fertilizing the land as a furrow cover film, use 45% chlorothalonil fumes with 1 kg of fumigation per mu before planting, and close the greenhouse for about 7 days of suffocation.

Colonization. Generally, it is planted in mid-March, and when the seedlings are just 3 leaves, 1 heart or 4 leaves, the seedlings are planted at about 30 days. Small varieties are planted in double rows according to plant spacing of 40 to 40 cm, with about 1800 plants per mu.

Large varieties are planted in double rows according to the plant spacing of 50 to 50 cm, with about 1600 plants per mu. 1 day before planting, the seedbed will be watered thoroughly, select strong and fast closed seedlings, good seedlings, try to make the roots more with soil transplanting, planting should let the root system stretch normally, after planting watering the root water, and the planting hole with fine soil to cover tightly, after watering 1 time a day, until the seedlings survive.

Temperature. The slow seedling stage is not ventilated, which increases the temperature of the shed and promotes rooting. The temperature of the shed should be kept at 25 to 28 during the day, 18 to 20 at night, and when the temperature of the shed exceeds 30 at noon on a sunny day, it can be properly ventilated.

After slowing the seedlings, the greenhouse temperature is controlled at 20 to 25 during the day and 12 to 15 at night, which is conducive to the differentiation of female flowers and early sitting melon. After sitting on the melon, keep the temperature to 22 to 26 during the day, 15 to 18 at night, and the minimum is not less than 10, increasing the temperature difference between day and night, which is conducive to nutrient accumulation and the expansion of the melon.

Fruit preservation. In early spring, when the temperature is low, it is necessary to take artificial pollination, generally before 9 a.m., pick the male flowers that bloom that day, remove the corolla, and gently apply it on the stigma of the female flower. or use plant hormones such as anti-falling hormone and zagolin according to the instructions for use.

Fertilizer water. Water according to soil moisture. When there is a shortage of fertilizer in the later stage, 10 to 15 kg of compound fertilizer per mu can be applied or foliar fertilizer can be sprayed.

Harvest broadcast.

Zucchini is mainly edible tender melon, and is harvested when it meets the requirements of commercial melons. Plants with weak growth should keep less melons and pick melons early. Do not damage the main vine when picking, and try to leave the melon stalk on the main vine.

How much does the temperature stay at night after the grapes have been puffed?

Greenhouse grapes should be watered in winter. Generally, after the shed begins to heat up before watering permeable, then according to the soil moisture in time, do not wait until the drought is serious before watering, otherwise it will cause flowers and fruits, and the yield is not high.

If you water too much before the greenhouse shouts acres of grapes, it will rot the roots.

When and how to water the grapes

1. Watering time.

1. Watering during germination. After mid to late March, when the soil has just thawed, the grapes sprout and are watered once after they are put on the shelves. At this time, irrigation can promote the germination of buds, and the buds of Xinling jujube grow faster after germination, laying the foundation for this year's growth fruit, often referred to as the second irrigation.

Sprout water. Irrigation requires a single pass, avoiding multiple watering to reduce ground temperature and affect germination rates.

2. Watering during the flowering period. In late May, watering is carried out 10 days before flowering to meet the large amount of water required during the flowering period, and the fruiting rate increases.

3. Watering during the fruiting period. The rapid expansion period of the fruit after flowering is the period when most of the water is required and should be watered immediately to allow the fruit to grow properly.

4. Winter watering. Winter branching and budding are closely related to autumn and winter drought, and the cold water before freezing the grapes can prevent winter and spring droughts, which is conducive to safe wintering. When the rain falls for a long time, drainage work is required.

Second, the watering method.

1. Germination stage: A large amount of water is urgently needed, and water needs to be injected 1 to 2 times to penetrate the roots. However, it is not advisable to over-watering to avoid affecting the temperature rise.

2. Before flowering: In arid areas, it should be watered about 15 days before flowering, which is beneficial for flowering and fruit set.

3. Berry swelling period: from the end of physiological decline to 50 to 80 days before fruit coloring, it is the berry swelling period. During this time, new shoots grow vigorously and the fruit begins to swell rapidly.

This is the peak time for grapes to absorb fertilizer and water. In addition, the temperature is high, and the leaf evaporation is large, and water is generally sprayed every 10 to 15 days.

4. After the application of autumn fertilizer: from the harvest of the fruit to the second year before germination, it is necessary to apply high-quality organic base fertilizer, which is generally called autumn base fertilizer. When fertilizing, the depth of the ditch needs to be up to meters.

Organic fertilizer and soil amendment are mixed with the topsoil and backfilled, then filled with water to allow it to sink to prevent air from passing through.

5. Before grape burial and cold protection: In the northern region, grapes should be watered once 10 days before the winter soil is buried to prevent frost resistance and early spring drought.
