How to water vegetables Whether to water a little bit a day or once a thoroughly

Vegetables are tender and juicy plants, and their growth and development processes require a large amount of water. Therefore, watering has become an important part of cultivation management.

Vegetable seedlings do not need much water, but they need careful management ability to cultivate strong seedlings of appropriate age. Before sowing, you must water enough seedbed water, sow after the water seeps down, and do not water the head water after sowing. At the seedling stage, it is usually necessary to keep the seedbed moist.

If the seedlings grow, they can be watered modestly to enhance the seedlings. Some vegetables should not be watered too much at the seedling stage, such as coriander, green garlic, open-field autumn cucumber, etc. Some seedlings with small and shallow roots, such as leeks, cabbage, amaranth, etc., should be watered lightly and frequently.

1 week before the seedlings are planted, the water should be controlled, the seedlings should be refined, and the roots should be strengthened; Before the seedlings rise, the furrow should be watered thoroughly to reduce the root damage when the seedlings are raised; When planting, seedlings are raised, planted, and watered at the same time. 4-5 days after planting, water the seedlings once a time. After the seedlings are slowed down, the water is properly controlled to enhance the rooting.

For some vegetables that use fruit as a commercial organ, it is usually not suitable to water from the early flowering stage to before fruit set, such as loofah, bitter gourd, lentils, peppers, etc., and should be watered when a batch of fruits is sitting. Some vegetables (green leafy vegetables, cabbage, etc.) that require more water during the growing season should be watered frequently to maintain their lush vegetative growth. For example, within 2 months after celery planting, it is advisable to water frequently, otherwise, the growth will be delayed.

In the middle and late stages of vegetable growth, the watering area should be judged according to the root-shoot ratio, such as chayote should be watered within 3-4 meters from the plant. For vegetables that continue to be picked (such as fungus, leeks, celery, etc.), do not water immediately after each harvest, because the wound is not healed, and watering is easy to cause erosion. Vegetables that need to be stored after harvest (Chinese cabbage, potatoes, green onions, etc.) should be watered less before harvest to improve their storage resistance.

In addition, when planting temperature-loving vegetables for watering in the cold season, it is necessary to choose a sunny day to water in the morning, and not in the afternoon or rainy and snowy days. Usually poured with warm water (6-10). In order to reduce the air humidity in the shed, you can take the film to pour dark water, to water enough with small water, not with small water.

For overwintering vegetables cultivated in the open field, it is advisable to pour enough overwintering water before the soil freezes. Planting cold vegetables in the hot and dry season, watering should be "cool weather, cool ground, cool water" when watering, that is, watering in the morning and evening, can be watered well water or shady river water. In the summer, after the rains, the well water should be poured to avoid the appearance of rotten roots.

Watering is actually quite simple!! Many plants can be kept slightly moist, but they must not be good at stagnant water, and their roots will rot. Then it is not to water in drought, watering can generally see the color of the soil, (1) when watering is slightly tan, when slightly damp it is light brown, if the surface of the potting soil becomes light yellow and a little whitish it is almost, (2) then you combine the softness and hardness of the soil (gently press with your hands), or twist the soil by hand, if the soil is powdery, then combine the two points - the result is good watering!

Watering If it is a small potted plant, you can take a large water basin, put the flowers in it and soak it after fetching water (note: the water level of the fleshy plant should not exceed the mouth of the pot, there should be a hole at the bottom of this, and then take it out for about 5 minutes and put it on the ground to drain the water.) If it's another plant, the water level can exceed the spout, and if it's dry, it will bubble, and when it stops bubbling, stop for 10 seconds and take it out).

So if yours is a big pot of plants, hehe, go and water it honestly, watering until you leak from the bottom of the pot may not be watered thoroughly, if it is very dry, the potting soil and the edge of the pot are separated, so it leaks quickly!! This kind of watering has to be done slowly, watering some and waiting, the soil absorbs it, and then watering it a little.

Watering can be done along the perimeter of the plant's roots, and if the pot is edged, very little soil will be absorbed.

Okay, typing is really tiring, I hope it helps you, I hope you raise flowers and flowers beautifully!

If you have plants to share, you can also do it.

His house-raised potted plants are fine.

Vegetables do not need to be watered every day in the non-vigorous growth period, and it is better to water once a day at a general interval of about three days, and once a day in summer if the weather is hot, and once a week in winter.

Vegetables are generally best watered in the sultry evening, and this time is also the time when Zhishiqiao and plants need water replenishment the most, so it is good to water the soil thoroughly at one time, so that the soil can be kept moist, and watering tap water can grow well.

The correct way to water vegetables.

1. Newly planted vegetables.

When vegetables are just planted in the soil dissipation, try to avoid overwatering, because the rhizome part of the plant is not fully developed, it is easy to appear because of too much water in the soil, resulting in difficulty in breathing of the plant.

2. Change the pot of vegetables.

When changing pots and transplanting vegetables, it is also necessary to avoid watering too much in the first few days, when the mature plant roots have just entered the new soil environment, and there needs to be an adaptation period to allow the plants to grow better.

3. Water quality. In the process of growing vegetables, they do not need too much water for high nutrition, so they can be watered with the most common tap water, and it is best to put the tap water in the sun for a while before use.

4. Watering frequency.

During the growing season, the water requirement of vegetables will increase greatly due to the rapid growth of the plants, and it is possible to water them once a day, or even twice a day.

Vegetables are overwatered.

If in the process of planting, the vegetable is overwatered, the vegetable can be moved to the sun, so that the vegetable receives full sunlight, the heat energy of the sun is used to evaporate the water, and the photosynthesis of the plant can be accelerated, and the water in the soil can be quickly discharged by the plant itself.

<>1. Vegetables are generally watered once every 2-3 days, and most of the vegetables have a relatively large demand for water, especially in the stage of small seedlings, as long as the soil is dry, there will soon be wilting and lack of water, so the chain needs to keep the soil slightly moist.

2. It should be noted that the water evaporation rate in the environment of the high-temperature shed in summer is also fast, and it can be watered in the morning and afternoon, or twice a day.

Vegetables are watered once a few days.

Generally, there are many kinds of vegetables, and most of them lack water in summer. Generally, you can water them once every two days to let them have enough water to grow, but in winter, you don't need too much water, and you can water them once every ten days. Before watering vegetables, you should check if the soil is dry.

If it is wet, you should not water it. In addition, do not water the leaves of vegetables when watering, as it will affect the growth of vegetables.

What kind of water to water the vegetables well.

1.Rain: Generally, when it rains, if there is no greenhouse, vegetables can be drenched in rain.

Proper rainwater is fine, but if there is too much rain, you need to build a shed for it. 2.Tap water:

Watering vegetables with tap water is very suitable. Generally, after its soil is dry, it can be properly watered, which is conducive to accelerating the growth of vegetables.

What to do if the vegetables are watered too much.

1.Ventilation: If there is moisture in the roots of vegetables, it needs to be ventilated in time, and faster air circulation can make the water evaporate faster.

2.Sanding: Generally, if you accidentally overwater a vegetable, you need to spread a layer of sand with good absorption capacity on its soil, and then let it fully absorb the water before removing the sand.

Vegetable seedlings do not need to be watered every day, and they can be watered every 3-5 days in spring and summer. When the temperature gradually drops in autumn, the frequency of watering can be gradually reduced, and once every 4 days is just right. In winter, when the weather becomes cooler, the vegetable seedlings grown in the greenhouse can also be watered once every 3 days.

Watering of vegetables depends on the humidity of the soil and the weather. Generally, the watering time can be extended in rainy days or low temperatures in winter, and it can be watered once every 2-3 days. Other times it is possible to water daily.

Try to choose before 9 a.m. and after 4 p.m., and the water sources are mainly well water and river water.

The correct way to water vegetable seedlings.

1.Freshly planted vegetable seedlings should not be watered immediately as if they were transplanted seedlings. That's because the root system of the vegetable is still fragile at this time, and because transplanting will be damaged, you can wait 3 days before watering.

2.Water vegetable seedlings appropriately during the growing season, as long as the soil can be kept moist, but do not wait until water is available. If watered too much, moist soil can cause poor respiration in the plant's root system.

Vegetable seedlings are overwatered and treated.

If there is water accumulation in vegetable seedlings, it is necessary to drain the water in time, dredge the field ditch as soon as possible, remove the water in the field, reduce the groundwater level, and shorten the time when the vegetables are flooded. If the vegetable seedlings are lodging, the lodging vegetables should also be straightened in time to reduce mutual squeezing, and the sediment on the vegetable stems and leaves should be washed off with water to prevent clogging the pores and cavities.

1. The planting water should vary from time to time.

In autumn, seedlings are generally transplanted in the afternoon or evening, and after planting, they should be watered closely, and if they are not watered thoroughly, they can be watered again in the early morning of the next day. When the temperature is low, it is necessary to pay attention to the weather changes at any time, and generally choose to transplant in the morning after bad weather. Usually watering should choose the cold tail and warm head period.

2. When to water"Three looks"

First of all, look at the growth of the plant to judge the water demand. For example, when the cucumber growth point shrinks into a ball, the stem is not stretched in a circle, the leaf color is dark green, the melon strips are dull, and the tip is pointed, it means that the plant has symptoms of water deficiency;

Secondly, look at the degree of dryness and wetness of the soil. Ensure that the soil is dry and wet, the early stage of growth is mainly based on appropriate water control, and the roots are taken down, and after entering the fruiting period, the plant water and fertilizer demand is large, and the number of watering should be increased.

Then it depends on the weather. This should be divided into two to see, one is to pay attention to weather changes in time, do not water before the rainy day, choose sunny days to water in the morning, reduce the situation of excessive humidity at night caused by watering in the afternoon, after watering on the same day, increase ventilation the next day, and reduce the humidity in the shed as soon as possible; The second is that the seasons are different, and the watering is different. At present, the plants have a lot of evaporation and a lot of watering, so the soil should not be too dry.

How to water vegetables in autumn.

1. Determine the variety.

When planting vegetables in autumn, it is necessary to water according to the varieties and growth characteristics of vegetables, for cabbage, cucumbers, cabbage and other vegetables with shallow roots and large leaves, it is necessary to water frequently, and the principle of not drying the furrow surface is to tomatoes, eggplants and other vegetables with deep roots, it is necessary to see dry and wet watering.

2. Master the period.

For the vegetables planted in autumn, it is necessary to water according to different growth periods, the water demand is large in the germination period of the seeds, and the bottom water should be irrigated after sowing, and the soil should be kept moist during the vigorous growth period of the root system, but not waterlogged, generally less watered or not watered, and the vegetables should be cultivated once after watering during the mature period.

3. According to the shape.

Before watering vegetables in autumn, it is necessary to determine whether to replenish water according to the shape change of leaves, the length of stem nodes, the thickness of wax powder and other appearance factors, such as open-field cucumbers, if the leaves droop and wilt at noon, it means that the plant is short of water, and it is necessary to replenish water immediately.

4. Observe the soil quality.

After planting vegetables in autumn, you can water through the dry and wet conditions of the soil, soil moisture is an important factor in deciding whether to water, when there is a lack of moisture, you should water immediately, when the moisture is suitable, cultivate and protect moisture, and pay attention to draining the stagnant water in the field when black moisture.
