What should be paid attention to when watering eggplant in greenhouses in autumn

Watering as long as keep the soil moist, not too much, do not ditch irrigation, it is best to use drip irrigation, if there is no drip irrigation can only ditch irrigation, but also can only irrigate horse water, that is, after the ditch is filled with water, after a few minutes immediately put away. In addition, do not irrigate in the evening to prevent excessive humidity at night and easy to occur.

Timely topdressing] After the plant survives, urea can be used in the early stage or with decomposed thin manure water and combined with spraying of new high-fat film to improve the effective utilization rate of fertilizer, and carry out tillage and weeding. In the flowering and fruiting stage, the fermented peanut bran or rapeseed cake can be mixed with superphosphate and potassium chloride, combined with soil on both sides of the furrow, and applied in a shallow ditch. In the peak fruit period, due to the poor soil fertility in the south, coupled with many years of continuous planting, the plant is prone to premature aging, in addition to topdressing fast-acting fertilizer, it can also be topdressing outside the roots, and combined with the spraying of vegetable fruit Zhuang Tiling to enhance the pollen fertilization quality of fruit vegetables, strong cycle fruit setting rate, promote fruit development, no deformity, no empty shell, no grains, good uniformity, improve quality, and make vegetables and fruits produce abundantly.

Water management] the southern winter is the dry season, less rainfall, dry climate, low soil moisture, should pay attention to irrigation drought prevention, irrigation before the weather conditions, can be ditch irrigation or use watering, but not flood irrigation. When irrigating, do "one shallow, two urgent and three cool", one shallow is the irrigation does not exceed the height of the furrow 2 3 3 4, the second urgent is the rapid irrigation and rapid drainage, and the third cool is the cool soil, cool temperature and cool water. In case of heavy rain and heavy rain, it should be drained in time, and spray the soil surface with 600-800 times of the new high-fat film, which can protect moisture and waterproof evaporation, sunscreen and drought resistance, heat preservation and anti-freezing, and prevent soil layer compaction.

Management method of eggplant after planting in winter greenhouse.

1. Control of greenhouse temperature: The suitable temperature within a week after the planting of eggplant seedlings should be about 30 degrees during the day and more than 15 degrees at night, so as to promote the occurrence of new roots of eggplant seedlings. After a week, when the new leaves of the eggplant seedlings begin to grow significantly, the temperature is kept at about 25 degrees Celsius during the day and 12 degrees Celsius at night to prevent the plants from growing too vigorously.

2. Control of greenhouse humidity: When the air humidity in the greenhouse is too high, it will aggravate the disease, and the ventilation management of the greenhouse should be strengthened. During the day, when the temperature inside the greenhouse rises to 25 degrees Celsius or more, ventilation is also carried out when the temperature outside the greenhouse does not drop below 15 degrees Celsius at night.

Cloudy days and a few days after watering, the air humidity in the greenhouse is also prone to be high, so the ventilation time should be extended, and when the temperature in the greenhouse is low during this period, it is also necessary to carry out short-term ventilation and dehumidification.

3. Light adjustment of eggplant shed: Eggplant shed generally adopts polyethylene drip-free film. In order to improve the light transmittance of the greenhouse film, 100 grams of flour can be used to spray 15 kg of water, spray the inside of the greenhouse film with a sprayer, once a week, in order to reduce the condensation of the greenhouse film and improve the light intensity.

Fourth, the shed eggplant fertilizer and water management: when the eggplant begins to swell and grows to the size of an egg, watering the stuffy shed, watering in the morning on a sunny day, it is advisable to fill the small ditch, pay attention to the temperature and moisture, and water the second water after half a month. Starting with the second watering, fertilizer should be watered according to the growth of the plant.

Combined with watering, 15 kg of diammonium phosphate, 10 kg of urea, kg of boron magnesium fertilizer, 1 kg of potassium dihydrogen phosphate, and about 100 kg of rotted chicken manure were applied each time.

Fifth, the greenhouse eggplant adjustment: winter warm greenhouse eggplant cultivation, the use of hanging seedlings (one plant two hanging rope) two branches to retain the method of two branches, retain the main branch and inflorescence under the leaf axils of a more powerful side branch, the rest of the side branches erased, into the middle of the fruit plant sealing, the lower part of the old leaves and yellow leaves in time to take out of the shed and bury. Only one fruit is left in each inflorescence, the rest of the flower buds are removed, and two branches of each plant grow side by side, and the branches should be erased in time.

6. Smearing flowers and fruits: In order to improve the fruit setting rate of greenhouse eggplant, smearing flowers is generally used. The time of use is to be in bud or just opened, and it is advisable to apply it today and bloom the next day.

Use a concentration of 20-30ppm, use a high concentration when the temperature is low, and reduce the concentration when the temperature is high. Be careful not to splash the liquid on the leaves or stems to avoid pesticide damage, and do not concentrate too much to prevent fruit cracking.

Should eggplant cultivation be heavily watered? What are the precautions for eggplant seedling?

1.You can water a lot, but not flooding, in the process of watering the eggplant, be sure to water the roots, and water thoroughly, to ensure that all roots can absorb water evenly. Because the root system has no taproot or taproot, and the root system is weak, furrow irrigation can be used to avoid soil erosion, and flood irrigation or direct irrigation with water pipe cannot be used.

2.Pay attention to the time of seedling divisionWhen eggplant seedlings grow 2 or 3 true leaves, it is the best time to divide seedlings. Before the seedlings are divided, the seedlings must be tempered.

About 5 days before seedling, the temperature should be reduced by about 5 degrees, mainly to ensure that eggplant seedlings can adapt to the temperature of the seedbed after seedling, promote slow seedlings, and improve the survival rate after transplanting. Especially in the hotbed and greenhouse seedlings, the ventilation openings should be appropriately increased during the day to extend the indoor ventilation and lighting time, so that the seedlings can quickly adapt to the new growth environment.

3.Pay attention to the seedbed to water the seedbed in the afternoon before seedling, and increase soil moisture appropriately to facilitate digging seedlings. When digging seedlings, pay attention to try not to hurt the roots, and transplant with soil.

After digging the seedlings, they are graded according to size and then transplanted separately. At the same time, care should be taken not to hurt the stems and leaves of the seedlings, so as to ensure that the root system of the seedlings can be fully stretched in the soil and avoid the root system being squeezed into a ball and curled and kinked. Then, care should be taken to prevent the seedlings from wilting in the sun.

Therefore, when the seedlings are divided, it is necessary to cover the film and shade the light. Watering immediately after transplanting and watering again the next day is conducive to slowing down the seedlings.

4.Attention should be paid to include nutrient soil, it is best to be able to implement the nutrient bowl seedlings, because the nutrient bowl can play a role in guaranteeing eggplant seedlings, and after planting, its survival rate can be almost 100%. If it is divided into seedbeds and seedlings, it is mainly planted in holes or furrows.

Dig a small trench in the seedbed according to the row spacing of up and down 12 cm, and maintain the depth of the ditch at about 4 cm, and then water a small amount of water in the ditch. When the water gradually penetrates into the soil and retains a little water, the seedlings are planted at a distance of 10 cm.

In the afternoon before the seedlings are divided, we should water the seedbed to increase the moisture of the soil appropriately and make it easier to dig the seedlings. When digging seedlings, be careful not to hurt the roots and transplant with soil. After digging the seedlings, they are graded according to their size and then transplanted separately.

At the same time, it is also necessary to pay attention not to hurt the stems and leaves of the seedlings, to ensure that the roots of the seedlings can be fully stretched in the soil, and to avoid the roots being squeezed into a ball and curling and kinking. Then care should also be taken to prevent the seedlings from wilting when exposed to the sun. Eggplant cultivation does not require a lot of watering, proper is fine.

When watering eggplants, be sure to do it in the evening, generally after 4 p.m. and not too early, if you encounter continuous rainy days, you should drain the water in time, and do not overdo it when watering; When dividing eggplant seedlings, we must pay attention to the time of seedling, do a good job of refining seedlings in the first 4 days of seedling, and water the seedbed in the afternoon of the day before seedling.

Eggplants need a lot of fertilizer water during their growth! The water requirements of eggplants vary depending on the stage of growth. The water requirement is less in the early growth stage, and the water requirement is increased in the flowering and fruiting stage, and the water requirement is the most before and after the full fruiting stage.

Irrigation should be carried out in a timely manner to ensure water supply. In production, according to the characteristics of eggplant that likes water and is afraid of water, we should pay more attention to water in spring and autumn, and pay attention to drainage in rainy summer. Watering method Eggplant watering process, water at the root system, watering should be thorough, to ensure that all roots can absorb water evenly.

Since the root system has no taproot or no obvious taproot, and the root system is weak, furrow irrigation can be used to avoid soil erosion, instead of flood irrigation or direct irrigation with water pipes.

There are skills in eggplant cultivation, and moisture is the key! Remember these two points, there are a lot of achievements, and you look good! When planting eggplants on the sowing date, it is necessary to pour enough "root water".

First of all, the planting area can be watered once to keep the internal soil moist for a long time and to dry the surface so that the water remains in the permeable layer. If you water too often, the relative humidity of the soil will increase, leading to the onset of disease in the later stage of the seedling stage. After transplanting eggplant seedlings at the seedling stage, they are generally not watered to make the seedlings adapt to the environment, promote the root system to absorb water and receive nutrients.

But don't let the seedlings die because of lack of water. One week after transplanting, the seedlings returned to normal growth. Water should be irrigated once to ensure that the leaves swell for photosynthesis, so as to produce the necessary nutrients for their own growth.

Bedding and watering are good for the growth of the root system.

The importance of water and fertilizer management at the seedling stage of eggplantWhy is water and fertilizer management so important for eggplant? This is because eggplants need a lot of nutrients to maintain normal growth when rooting, so they need to be fertilized in moderation. Old farmers who have planted eggplants know that a large amount of organic fertilizer should be used as a base fertilizer before planting, because the fertilizer efficiency of organic fertilizer is relatively slow.

In this way, the eggplant can remain green for a long time, or grow vigorously, and the yield and quality will be greatly improved. So how should water and fertilizer be managed after that? Growing eggplants this way can slow down the seedlings very quickly, and there are no pests!

The experience of this old farmer is worth collecting, how to drip irrigate the vegetable garden? We need to pull some tubes while laying the plastic film to prepare for our early fertilization. Remember, there is a difference between pulling a tube in a greenhouse and in the open air.

For example, our simple open-air can be double-laid pipe. Pull the tube to the middle, or you can pull two tubes. The plumbing here refers to the drip irrigation pipe.

Farmers can buy it in agricultural material stores or building materials stores. If your garden area is relatively large, you can also go to a special pipe laying agency, come to your site, and design the thickness, diameter, and length of the pipe according to the water consumption, water storage, and pump pressure of your community. After repairing the pipeline, let's talk about how to manage water and fertilizer.

How do you water eggplant's root? We know that eggplant seedlings need to be watered after transplanting, so it is very important to pay attention to the root water. Especially when you plant seedlings, we recommend bringing some nutrient soil.

In addition, when watering the roots, it is better to add some insect repellent. For example, if you used to have nematodes on the land, add some insect repellents. Of course, underground insect medicine is also essential, otherwise underground grubs, grubs and other pests will bite the seedlings, and if there is a wound, it is very unfavorable to the slow seedlings of eggplant.

Immediately after planting eggplants, do not water them for the first 5 days, and be sure to look at the weather when watering, and never water them after rainy days. Be sure to drain the stagnant water after the rain. When watering, you should choose around 5 p.m., so that it will play a certain role.

When watering, it is best to water once every two days, and be sure to water the ground thoroughly in the morning, so that the vitality of the watered eggplant is very tenacious, and the eggplant is also particularly nutritious.

You should use the habit of watering a small amount at a time, but often so that the eggplant soil can retain enough water.

An irrigation system can be set up in the greenhouse, so that the eggplant can be watered regularly and quantitatively, and the amount of watering can be controlled.

Hello dear dear, it is a pleasure to serve you: the greenhouse eggplant is watered once every 3 to 4 days in the early stage; 1. Water the eggplant once every 3-4 days. 2. According to the soil moisture and the outside weather temperature, it is generally watered once every 7-10 days.

3. Watering skills of eggplant: 3-4 days after planting, water a slow seedling water, start squatting seedlings after slow seedlings, and start to irrigate the dark ditch when the door eggplant stares (about 13 days of envy), and after the ground temperature reaches 18 °, the light and dark ditches can be irrigated. 4. Watering once 3-4 days after eggplant planting, start squatting seedlings after slowing down the seedlings, and after the ground temperature reaches 18C, the light and dark ditches can be irrigated.

5. Generally, 7 10 days to water once, the specific situation is based on the weather conditions and field moisture. 6. According to the weather conditions, it is generally 7-10 times to pour once. I wish you a happy life!

Hope mine is helpful to you ha.

7 to 10 days before planting, the eggplant seedlings were refined at low temperature to adapt to the environmental version with low temperature and large temperature difference between day and night in the greenhouse in early spring. When the shed temperature is not lower than 10, and the ground temperature of 10 cm is stable above 12, choose a sunny day to plant in the morning. After planting, it is best to carry out multi-layer mulching such as small arches.

After the door eggplant is harvested, the outside temperature rises, and the ventilation time should be appropriately advanced, and the vent should be from small to large. When the outside night temperature reaches more than 15, ventilate day and night, and when the outside temperature is stable above 22, you can gradually remove the greenhouse film or leave only the top film, and cover the greenhouse film with a shade net. It is necessary to remove the old leaves and axillary buds below the root eggplant in time.

After the four door buckets, some areas in the "eight-sided wind" after the big buds, leave 2 3 leaves in the upper part of the flower buds to pluck the top, which is conducive to early maturity, high yield and upper fruit expansion, and timely removal of axillary buds, in the middle and late stages of picking off the lower disease, old, yellow leaves, in order to facilitate ventilation and light, reduce nutrient consumption, and promote fruit growth and development. Eggplant planting in spring greenhouse is early, the temperature is often below 15, and the lack of light is easy to cause flower drop and bud fall and form deformed fruits. At the time of flowering, 30 40 mg of 2,4-d solution or 40 50 mg of tomatoline solution are applied to the calyx or flower stalk with a brush to prevent flower fall and promote fruit expansion.

The application of flower-preserving and fruit-preserving agents can add 1% Suclin or 1% chlorothalonil to the solution, which has a certain control effect on gray mold, sclerotinia and cotton blight in fruits.
