When is the tomato field managed to be watered? What are the common methods?

When tomato field cultivation and management, it is necessary to constantly adjust the law and amount of watering, you can water from time to time in the early stage, and water more after the seedlings grow, and in the later stage, you can actually imitate the rain for irregular watering.

When watering tomato cultivation management, it is necessary to pay attention to watering thoroughly during the cultivation of seedlings, which will help the germination time to withstand relatively well. Then, after about a month or so, it is necessary to do a second watering.

It needs to be watered when planting, and it should be watered every five or six days to promote growth, and when it is time to bloom and bear fruit, the watering should be more active to ensure that the water is sufficient to make the tomato better.

It should be between 3 and 5 months of growing leaves, this time you should pay attention to watering, in order to grow particularly strong, the first method, is to use irrigation to water, the effect is very good, the second point, is to use a pump to water, the effect is also very good, the third point, you can buy a kettle, and then along the edge of the middle of the tomato field to water.

When tomatoes are already 3-4 bunches of fruits, they are generally watered with fertilizer water, that is, they will be mixed with a little water-soluble fertilizer at the same time as watering, not compound fertilizer, top dressing is generally water-soluble fertilizer, water-soluble fertilizer is full of nutrition, fast dissolution, high absorption and utilization rate, which can meet the high nutritional needs of pepper growth period, which can not be done by conventional compound fertilizer, and water-soluble fertilizer is also in line with agricultural development, water and fertilizer integration, water and fertilizer saving.

Tomato moisture management.

Watering when planting, can maintain the balance of water, prevent the plant from dehydration and death, this watering requires more water, to ensure the penetration of the planting soil, planting in winter and spring, has been watered dark water as well, can prevent the ground temperature from dropping more, planting in summer and autumn, generally using watering water, watering water consumption is large, keep moist for a long time, is conducive to slowing down seedlings.

When spring tomatoes are planted, the seedlings are generally older, and they are generally no longer watered during the period from the time of slow seedling watering to the first ear of fruit sitting. The seedling age of summer and autumn tomato planting is small, after slowing the seedling, it is necessary to promote the rapid growth of seedlings, timely watering, and pay attention to cultivation after watering.

Flowering period of water control squatting seedlings, flowering rarely watered, unless the drought is serious, this period is mainly to keep the soil loose, the surface dry, promote strong seedlings, to ensure that the root system expands downward, for the future plant vigorous growth, lay a good foundation.

When the fruit water sits 2-3 in the first ear of fruit, it should be watered in time to promote the fruit, pay attention to the watering time, the water is watered early, and the plant will often grow vigorously, the vegetative growth will be too vigorous, and it is not easy to set the fruit or delay the fruit setting period. After the watering is completed, the growth of the plant is stunted, and although there are many fruit sets, the leaves become smaller, the growth is slow, and the yield is reduced.

Watering in the full fruit period is carried out after the first ear fruit sits, at this time the tomato has entered the stage of flowering and fruiting, fruit expansion and maturity, the plant growth is large, the organs of each part have a large demand for water, generally watering once in the early 5-6 days of fruiting, so that the ground is dry and wet, and shallow hoeing can be carried out after watering, otherwise continuous watering is easy to cause ground plate knots, and the evaporation is large.

Watering is done to keep the soil moist and meet the plant's need to absorb water. In addition, it can improve the air humidity between the ground and the plants, and around noon in dry weather, sprinkler irrigation or sprinkling water on the plants can be carried out when conditions permit, and potassium dihydrogen phosphate can be used with Ribery Yanwo powder to reduce the temperature of the foliar surface and reduce the occurrence of sunburn and virus diseases.

Tomato field cultivation management, when do you need to water it? What are the commonly used methods? When to water tomatoes:

Squat down the tomato seedlings (the first fruit is the size of a walnut) and water. Generally, the seedlings are watered once at the seedling stage, and the water is controlled until the first spike grows to 2-4 cm of the straight stem of the young fruit, and then every 10-15 days according to the water content of the seedlings. Water 3-4 times throughout the growth period, and irrigate 60-110 cubic meters of mu each time.

Irrigation should be drip irrigation furrow irrigation, and flood irrigation is strictly prohibited to avoid rotten fruits and diseases. At the same time, tillage should be strengthened to prevent seedlings from freezing due to lack of water. For strip farmland with severe drought, it is advisable to open ditches to divert water as soon as possible to increase soil moisture.

The first irrigation is followed by the second irrigation, and then the third irrigation is carried out according to the management situation until the fruit expansion stage, and then the later irrigation is carried out according to the management situation.

Watering must be carried out according to the characteristics of different growing periods. In general, tomatoes are watered when planting, and then watered again 3 to 5 days after watering, until the first spike is as big as the yolk. As a result, the early planting area was small, the leaf transpiration was small, the number of fruits was small, and the ventilation was small.

In general, water every 7-10 days (the amount of water should be small). Subsequently, with the growth and development of plants, the number of fruit sets, the aeration increased, and the transpiration increased. The number of days between watering should be shortened and the amount of watering increased should be increased to keep the soil dry and moist (mainly moist).

During harvesting, the soil should be kept moist to increase the weight of the individual fruits.

Watering according to the characteristics of the stubble. For overwintering tomatoes grown in greenhouses with warm winters, watering is usually not required until the first panicle is in place, except for adequate planting water during planting and timely tillage to maintain soil moisture. After watering, it can be covered with plastic film to keep it warm and moist.

If necessary, pour a small amount of water under the film so as not to reduce the temperature of the ground. When the weather warms up, increase the amount of watering to meet fruit growth and development. Greenhouse tomatoes cultivated in early spring should be watered in time after fruit set to meet their water requirements.

Water according to growth. The plant is dark green in color, the leaves are shiny, the green is flat, and the heart leaves are stretched, showing uniform and moderate moisture. If the heart leaves shrink and not, the leaf color is dark green, and there is a slight leaf drooping on a sunny day, this is a sign of dehydration, so it is necessary to replenish water in time.

If the heart leaves are over-expanded, the leaves are large and thin, and the leaf surface spits out too much water, it is a sign of excessive water, and the water should be controlled to prevent overgrowth.

The amount of time you water in the greenhouse every day. During the growing season, water in the morning on sunny days, and ventilate and drain moisture after watering. It should not be watered in the afternoon, evening or rainy day, otherwise it is easy to cause excessive humidity in the shed and cause downy mildew and other diseases; It is also not advisable to water at noon, so as not to affect the physiological function of the root system with high temperature watering; In the middle and late stages, when the weather is hot, the greenhouse can be ventilated day and night.

It should be watered in the morning and evening to help with cooling. Water when picking fruits. Tomatoes should be watered before harvesting, which can increase the commodity value of the fruit.

Hello, the fertilizer and water management of tomato melon and fruit period depends on which variety you plant. Early-maturing varieties are generally watered when the fruit is set, and mid-late varieties are watered when the fruit grows to the size of egg yolk. Water every 4-6 days during the peak fruit period to keep the ground dry, promote the growth of seedlings and fruits, and facilitate the absorption of calcium and reduce the occurrence of umbilical rot.

Pay attention to drainage during the rainy season to prevent waterlogging.

Usually water properly, and a lot of watering is required when the first panicle of tomato grows to about one centimeter in diameter; The most common method we use is to irrigate directly in the form of sprinkler irrigation or flood irrigation.

Generally, you can water in the morning and evening, the temperature during these two periods is not particularly high, and the tomato can be better absorbed after watering. It can be watered with a watering can, or with a scoop.

It is generally best to water in the early morning or evening, and generally use potassium fertilizer to better cultivate tomatoes.

Tomatoes are a common vegetable, and in its growth process, watering is very important, which is directly related to the growth and development of tomatoes and the yield of tomatoes. Next, I will actually tell us how tomatoes should be watered to ensure the yield of tomatoes from planting to harvest. Tomato watering should not be carried out according to the length of time, but must be watered according to the growth and development of tomatoes, growth and development stage, weather conditions, etc., so as to ensure that the tomato yield profit is maximized.

Transplanting and watering: Tomato seedlings should be watered habitually after the time constant, and the temperature is usually watered once every 2-3 days. The amount of watering is dominated by less, the soil layer is moist and the most suitable is not to water too much, otherwise the tomato seedlings will take root and die very easily.

Watering is best done with a watering can that waters the flowers, as it is very easy to manipulate the flow of water. From the perspective of the regularity of tomato fertilizer demand, the amount of fertilizer at the seedling stage is small, but the nutrition is comprehensive. Abundant nutrients, beneficial to the growth and development of roots, stems, leaves and flowers.

From the time of transplanting to the first ear of fruit sitting, the amount of fertilizer increased and <>

In general, most of the basal fertilizer and soil nutrients can be achieved. If there is too much nitrogen, it is easy to cause madness. From the moment the first ear of fruit sits to the time it is obtained, the amount of nutrients absorbed by the plant surges, and sufficient fertilizer must be provided.

In addition, attention should also be paid to the hazards of environmental conditions to top dressing. In the case of drought, the demand for nitrogen increases; Clammy and cold, the need for potassium and phosphorus increases. The nutrients at the seedling stage of tomato are mainly provided by bed soil.

If the trace elements in the bed soil are abundant and the types are complete, the growth and development of seedlings can be healthy, promote early flowering, and grow and develop quickly. Tomato seedlings have a long seedling stage, and they usually do not produce enough nutrients in the middle and late stages of pregnancy. When something like this happens, it should be mixed with watering and <>

Top dressing is sufficient for manure or urea solution. If the seedlings are raised in greenhouses, carbon dioxide can be added to promote the growth and development of the seedlings. Fertilize as needed.

In tomato production, the intake of various nutrients by tomato plants is not only suitable, but also the highest. In general, when the absorption rate of trace elements reaches an appropriate pointThe plant growth and development are abundant, and the yield is the largest; However, when the intake is at the highest level, the maximum yield may not be obtained. Therefore, it is necessary to grasp the most appropriate situation when applying fertilizer.

When growing tomatoes. Be sure to pay attention to his lighting status. Tomatoes need enough sunlight to make the tomatoes grow better.

It is also necessary to ensure its temperature, if the temperature is lower than 15, the tomato will not be able to flower and pollinate normally. Do not let the temperature of the tomato be higher than 35, too high a temperature will also hinder its growth and reduce the yield of the tomato. In terms of soil selection, tomatoes do not have high soil requirements, but it is better to choose fertile soil.

Tomato roots need good air permeability, you can choose some soil with good air permeability for planting.

It is important to pay attention to the fruit management of tomatoes, and also to pay attention to temperature control. It is necessary to pay attention to the way of planting, the planting density, the management of the fruit, the prevention of diseases, the process and time of control, and the light.

Be sure to water properly, and also pay attention to the time of sunlight, do not expose to the sun for a long time, and pay attention to the proper use of fertilizer, be sure to prevent pests and diseases in advance.

5,000 kg of high-quality rotted mixed fertilizer is required as base fertilizer and concentrated fertilization accounts for 50% each, and organic fertilizers containing phosphorus and potassium such as superphosphate, bone meal, chicken and duck manure are added, which can not only obtain high yield, but also improve fruit qualityAfter 3-5 days of planting, the color of the heart leaves of the tomato changes from old green to tender green, and when the growth point begins to grow, it is necessary to water the seedlings once, which is called the water of the tree by our people. The amount of water to slow down the seedlings should be large to ensure soil moisture, promote the root system to take new roots as soon as possible, and take root in the soil.

After the land has been selected for the cultivation of tomatoes, it is necessary to fertilize the land, which is called base fertilizer, and the base fertilizer carried out here is mainly organic fertilizer (after fermentation of animal manure), and this amount is also based on experience, analysis of the soil. Extra-root fertilization, that is, foliar fertilization, can be applied once in milliliters of triacosanol, 1% potassium dihydrogen phosphate or superphosphate during the flowering period, and then applied again every 10 days. This increases fruit set, promotes fruit growth, and ripens up to 5 days earlier.

Small water watering (avoid flood irrigation), fertilizer with water (balanced water-soluble fertilizer + biological regulation function water-soluble fertilizer in Mumei soil), swelling period, leaf spray Aomeijia chelated calcium + borax + potassium dihydrogen phosphate, root chong high potassium water-soluble fertilizer + Mumei soil biological regulation function water-soluble fertilizer through rotary tillage to mix organic fertilizer and soil evenly, rotary tillage depth to 20 cm is appropriate. After rotary tillage, the ridge width is 60 cm, the height is 20 cm, and the distance between the two ridges is 80 cm. The two-row planting mode of one ridge was used for cultivation on the ridge, and two drip irrigation pipes were laid on each ridge.

It is necessary to achieve the principle of water and fertilizer synchronization (water and fertilizer integration), apply water-soluble fertilizers of good quality, and filter irrigation to prevent drip hole blockage from affecting the use of irrigation equipment. The life of tomatoes goes through the germination period, seedling stage, flowering period, fruiting period, and more than 200 days of growth period, and the amount of fruit is large, can you not need a lot of fertilizer? Therefore, in production, most of them are based on organic fertilizer, and they also pay attention to the application of nitrogen, phosphorus and potassium.

The soil must be moist, and the water and fertilizer must also be nutritious, and it must be properly treated, which is a reasonable requirement, and in this way, the tomato can become more and more vigorous.

After planting tomato seedlings for 5 days, the seedlings should be watered once, before the tomato bears fruit, watered every 8 days or so, in the fruit expansion period of the tomato seedlings, it should be properly watered, you can water every 6 days or so, and the tomato grows slowly in winter should be watered less. During fertilization, organic fertilizer was applied at the seedling stage, nitrogen fertilizer and phosphorus and potassium fertilizer were mainly applied during the growth period, and superphosphate was mainly applied at the fruiting stage.
