How often do greenhouse tomatoes need to be watered?

How do you water tomatoes properly? What time is the right time to water tomatoes?

It is understood that tomato is a common vegetable and fruit product that is favored by consumers. In order to maintain the high quality and yield of tomatoes during the winter months, it is necessary to do a good job of growing and managing tomatoes. So how to water tomatoes correctly, let's take a look!

How do you water tomatoes properly?

1. The number of watering times and the amount of watering.

Due to the different stages of tomato growth, the appropriate watering time and watering time should be mastered. Generally, in severe winter, when the temperature and ground temperature in the shed are low, the amount of water should be small, the interval should be long, and the irrigation should not be flooded, so as to prevent low temperature and high humidity from causing tomato root degumming. When planting seedlings, they should be watered slowly in time, and the water should be properly controlled during the growth period of low-temperature tomatoes. When the first fruits of tomatoes begin to swell, the water content should be gradually increased so that the soil moisture content in the greenhouse is not less than 20%.

Peak periods. 2. The choice of watering time.

On sunny days in the morning, you should choose the time of watering and try to use well water. Avoid afternoons, even cloudy days.

or cause illness because of excessive humidity in the shed.

3. There should be a difference in watering on cloudy and sunny days.

The amount of water should be gradually increased on sunny days with high temperatures, and less irrigation on cloudy days or no irrigation, and no watering on continuous cloudy snow days. When the weather changes from sunny to cloudy, the amount of water should be gradually reduced, the time should be extended, it is a combination of watering and fertilization, and the ventilation after fertilization should be reasonable.

4. Watering according to different growth periods.

Under normal conditions, tomatoes are planted at the time of watering, and after 3 to 5 days of watering, the seedlings are watered again. When planting seedling water or planting water, water and soil should be used to promote rooting and strengthening. It will be poured again. In the early tomato stage, leaf transpiration.

Small, small number of fruits, small amount of ventilation. Usually, water can be poured in 7 to 10 days, and the amount of water should be very small.

Later, with the growth and development of plants, the number of fruit spikes increases, the aeration increases, and the transpiration increases, the watering interval should be shortened, the water should be increased, and the soil should be kept dry and moist (mainly wet), generally watering for 5 7 days, and the harvest period should keep the soil moist, or to increase the weight of a single fruit. When watering, you can also properly apply water-soluble fertilizer to supplement nutrients.

Tomatoes have different water requirements at different stages and different time periods of watering.

Under normal circumstances, tomatoes are watered while planting, and then watered again after 3 to 5 days after watering, until the first ear of fruit sits down such as egg yolk size and then watered again, the result is that the early planting is small, the foliar transpiration is small, the number of fruits is also small, and the ventilation is also small, generally 7 to 10 days to water a water, and then with the growth and development of the plant, the number of fruits increases, the ventilation volume increases, the transpiration increases, the watering interval should be shortened and the amount of watering should be increased, the soil should be kept dry and wet, and the soil should be kept moist during the harvest period to improve the weight of a single fruit. In addition, greenhouse tomatoes should also pay attention to fertilization management, and the growth period is 7-10 days old, and the water-soluble fertilizer is applied to Bica, which has a good effect.

Summary. Hello, glad for your question. The amount of tomato watering in the greenhouse in the medium is 75%-80% humidity.

Watering according to the growth period: tomato requires soil relative humidity of about 80% in the germination period, because seeds need to absorb a lot of water during germination, and soil relative humidity is required to be about 60% at the seedling stage. However, if it is too dry, it will also affect the differentiation of flower buds, and it is generally controlled watering after planting, but it should not be excessive, and the minimum should not be less than 60%.

Generally speaking, tomatoes are watered while planting, and then watered again after 3-5 days of planting, until the fruit yolk is the size of the egg. As the plant grows and develops, if the number of fruits is large, the amount of ventilation increases, and the transpiration will also increase, so it is necessary to control the humidity at about 75-80% and increase the amount and frequency of watering.

Hello, glad for your question. The amount of filial piety in the middle of the greenhouse tomato is 75%-80% in the pin hole. Watering by growth period:

Tomato requires soil relative humidity of about 80% in the germination stage, because seeds need to absorb a lot of water in the germination process, and soil relative humidity is required to be about 60% at the seedling stage, so it is necessary to control the water at this time, which is conducive to the growth and development of the root system. However, if it is too dry, it will also affect the differentiation of flower buds, and it is generally controlled watering after planting, but it should not be excessive, and the minimum should not be less than 60%. Generally speaking, tomatoes are watered while planting, and then watered again after 3-5 days of planting, until the fruit yolk is the size of the egg.

As the plant grows and develops, if the number of fruits is large, the amount of ventilation increases, and the transpiration will also increase, so it is necessary to control the humidity at about 75-80% and increase the amount and frequency of watering.

How many days do you pour it?

How many cubic meters is the amount of water?

Water once every 7-10 days. Use 10-15 square meters of water per acre.

Dapeng tomatoes generally use the watering method under the inter-ridge film, this watering method can reduce the disease of Dapeng tomatoes, when the temperature is low in winter, it is necessary to water less greenhouse tomatoes, and the watering time is suitable for sunny mornings, pay attention to the need for more watering in high temperature weather, less watering in rainy weather, and do a good job of ventilation and drainage after watering.

1. Watering method

Greenhouse tomatoes can be watered under the ridge film, covered with plastic film or dry wheat straw and straw between the ridges, and then water is poured into the plastic film, watering using this method can increase the low temperature by about 5, and can also reduce the air humidity, so that the greenhouse tomatoes can reduce the disease.

2. The number of waterings

Tomatoes in different seasons and different growth periods have different water requirements, when the temperature is low in winter, it is necessary to reduce the number of watering, and the watering interval should be longer, otherwise the high temperature and low humidity environment is easy to make the tomatoes root, and the soil moisture content should not be less than 20% during the greenhouse tomato fruiting period.

3. Watering time

Watering greenhouse tomatoes, you need to pay attention to the watering time, generally in the morning of a sunny day watering is the best, should not be watered in rainy weather, otherwise the humidity in the greenhouse tomatoes is too high, tomatoes are easy to produce diseases, watering after the need to do a good job of ventilation and moisture drainage, so that tomatoes can grow healthily.

4. Precautions

Watering tomatoes in greenhouses should be based on the weather and soil and soil moisture, when the temperature is high on sunny days, pay attention to watering more, rainy weather, it is best to water less or not watering, if there is water in the soil, it is necessary to drain it in time, and watering can also be combined with fertilization.

Tomatoes should be watered once every 3-5 days after planting.

Tomatoes are in the seedling stage, grow fast, need a lot of water, generally water once every 1 to 2 days, keep the soil moist, be careful not to accumulate water, so as not to root the roots. Watering is sufficient once every 3 to 5 days after the fruit setting period. Tomatoes should be watered in the morning or evening, not at noon.

Tomatoes can tolerate drought, but not waterlogging, and the soil requirements are not very strict, so in order to obtain high yields, it is necessary to choose a deep soil layer, loose and fertile, and strong water and fertility retention. In the middle and late stages of plant growth, the lower old leaves can also be appropriately removed to improve ventilation and light transmission; It is necessary to top in time to improve the fruit setting rate and promote fruit ripening.

Tomato cultivation techniques

1. Prepare the seeds.

There are many varieties of tomatoes, so you can choose your favorite varieties and prepare full, full, healthy, and high-quality seeds. Before sowing seeds, the seeds should be sterilized, wrapped in gauze, soaked in 50 water for 10 minutes, or can be soaked in 10 sodium phosphate solution for 20 minutes, and then the seeds should be cleaned and soaked in 30 warm water for 23 hours, which can promote the germination of seeds as soon as possible.

2. Sowing seeds and raising seedlings.

The temperature suitable for the development of tomatoes is 24 26 , which can be sown in the spring, and within the suitable temperature range, it can promote the germination of tomato seeds. Prepare loose nutrient soil, sow the seeds evenly into the soil, cover with thin soil, maintain the moisture of the soil, wait for the seeds to take root and germinate, under normal maintenance, the seeds will germinate in about 3 4 days.

3. Carry out colonization.

When the tomatoes grow two or three true leaves, they can be planted, and the ground temperature needs to be stable at more than 10 when planting, which can be conducive to root growth and improve the survival rate. Tomato seedlings are removed from the soil, carefully planted in the soil, sprinkled with appropriate water and kept in the sun.

Water once every 3-5 days.

It can play a role in slowing down the seedlings, and then water them again when the first ear fruit sits. As a result, it can generally be watered every 7-10 days in the early stage, and can be watered every 5-7 days as the tomatoes grow and develop.

Tomatoes do not have a fixed number of days to be watered, and generally follow the watering principle of seeing dry and wet. Watering is carried out according to the characteristics of tomatoes in different growth periods, and in general, tomatoes are watered while planting.

Tomatoes are available in the following types:

1. Xia Fan (Jiangsu): extremely early maturing variety, self-capping type, high round fruit, good pink quality. The weight of a single fruit is 180-200 grams.

High resistance to tobacco mosaic virus disease, medium resistance to cucumber mosaic virus disease, resistance to wilt, resistance to cracked fruit, resistance to transportation, yield of 5000 kg per mu, suitable for off-season early maturing cultivation and overwintering cultivation.

2. Wanfen No. 2: early-maturing variety, 3-5 inflorescences capped, the 5th-6th node of the first flower, the fruit is high round, pink, and the weight of a single fruit is about 300 grams. It has strong disease resistance, with a yield of 6500 kg per mu, and is suitable for dense cultivation in greenhouses in spring and autumn.

3. Powder Queen (Beijing): early maturity, unlimited growth type, high resistance to tobacco mosaic virus disease, medium resistance to cucumber mosaic virus disease and resistance to tomato leaf mold, the fruit is nearly round, pink, wide adaptability, and can achieve high and stable yield in different types of protected areas and open field cultivation.

4. Dahong No. 1: Introduced from the United States, medium-ripe variety, with many ventricles, thick walls, thick skin, not easy to crack the fruit, high solid content, not easy to flow juice, and red fruit is resistant to storage and transportation. Infinite growth type, the fruit is many and large, the fruit is round, the average weight of a single fruit is about 400-600 grams, the maximum can reach 1225 grams, and the yield per mu can reach 8000-12000 kg.

This variety is resistant to early blight, virus disease, low temperature and low light, and is suitable for cultivation in protected areas in winter and spring.

Tomatoes need to be watered every 3-5 days after planting, after the end of the slow seedling, the first time the ear fruit grows out in the watering once, now the plant is not big, the leaves are small so the watering is not too much, as the plant grows a little more, it will be watered once in 3-4 days, and the tap water and river water can be used when watering.

After the tomato seedlings bear fruit, the first fruit is like the size of a walnut and begin to water, a sedan chair like a seedling stage to transplant the seedling water, control the water until the first ear of the fruit swells to the young fruit straight stem 2-4 cm when watering two water, and then irrigate every 10-15 days depending on the moisture of the seedlings.

Tomatoes can be watered under the film according to the need, so as not to reduce the ground temperature, with the growth and development of the plant, the number of fruits increases, the amount of ventilation increases, the amount of transpiration increases, the watering interval should be shortened and the amount of watering should be increased, keep the soil dry and wet or wet watering principle.

Tomatoes are watered with what water.

Tomatoes should be watered with unpolluted water, or natural rainwater, in addition, watering it should be done not only to pay attention to the method, time, but also to the water quality.

1. Well water: During the rainy season, it is very suitable to collect the water and use it to water the tomatoes. Rainwater is neutral water with a high oxygen content, which prevents soil from compacting and allows plants to grow stronger.

2. DrainageIn the rainy season, it is necessary to pay attention to draining the stagnant water, if there is stagnant water for a long time, it is easy to infect fungi, and it is also easy to cause root rot, which will affect the growth.

What to do if the tomatoes are watered too much.

1. Potted plants: If it is planted in a pot, move it to a ventilated place, and strengthen the light to promote the evaporation of water as soon as possible.

2. Ground planting: If it is planted in the ground, it should be drained. Usually loosen the soil, but also more ventilation, so that the water will evaporate faster, reduce the damage to it, if the water is more serious, it is recommended to add new soil to help absorb water.
