How to manage pineapple in winter? How should pineapples be managed after flowering?

During the growth of pineapple in winter, sufficient sunlight should be given to avoid low-temperature frostbite in winter, and the temperature should be controlled between 5 and 10. If planted on land, it can be covered with a layer of plastic film, and the amount of watering can be controlled. It does not require fertilization of the plant and can also be properly pruned in winter to make it grow better.

Winter method of pineapple.

1.Plenty of light.

Pineapples are not very cold resistant. Generally speaking, during winter maintenance, it needs to be exposed to full sunlight so that pineapples can continue to photosynthesize and better promote their growth. It also prevents pineapples from getting frostbite at low temperatures in winter, helping pineapples survive the winter safely.

2.Temperature control and heat preservation.

In fact, the method of wintering pineapple is very simple. Not only does it usually need to be placed in full sunlight, but the growing temperature should be controlled between 5 to 10. If planted on land, it can be covered with a layer of plastic film, or it can be maintained with a shed, which allows for better growth.

3.Water control and fertilizer stopping.

Watering and fertilizing are also important if you want your pineapple to survive the winter safely. Don't water and fertilize blindly in winter. You can water the soil every half month. You don't need to fertilize the plant, otherwise it will affect the normal growth of the plant. You have to pay attention to the breeding in winter.

4.Trim properly.

In fact, during the winter propagation of pineapples, it can be pruned properly. When the climate gradually cools down in winter, all the dead leaves, old leaves and diseased leaves of the pineapple can be cut off, which can concentrate the nutrients in the soil and avoid frostbite of the pineapple root in winter, which is not conducive to the normal growth of the plant.

5.When potted pineapples are maintained in winter, they need to pay attention to adjusting the temperature, covering well, ensuring light and proper water control, the temperature should be above 5 degrees Celsius, and fertilization needs to be stopped in winter.

In short, as long as we understand the minimum temperature requirements of pineapples in winter, control the temperature and keep warm according to the habits of pineapples, and adopt correct and scientific management methods, we do not have to worry about the safety of potted plants for wintering. In spring, when the ground warms up, a pot of vibrant potted pineapples will appear in front of you. Pay attention to maintenance in spring and summer, and you can taste the sweet and sour fruity flavor of pineapple.

Pineapples are in bloom in winter, so they need to have enough fertilizer, usually every two weeks to apply thin organic liquid fertilizer, such as soybean cake, sesame sauce residue soaking, soybean soaking liquid or fermented rice washing water.

Pineapples should ensure that they have sufficient sunlight in winter, keep the temperature warm, and then water a little and stop fertilizing, so that pineapples can survive the winter smoothly.

Pay attention to the temperature, the temperature should be controlled at 23 degrees to 25 degrees, the branches and leaves should be pruned regularly, the ventilation work should be done, and when using pesticides, try to choose at 10 o'clock in the morning, when it rains heavily and when it snows, do not use pesticides.

After the pineapple blooms, the fruit swells rapidly, and it is necessary to remove the crown buds in time, strengthen fertilizer management and pest control, promote fruit expansion, and prevent pests and diseases, so as to improve yield and quality. The specific management technical measures are as follows. Pick the crown buds, about 20 days after the pineapple blooms, pick the official at the top of the pineapple fruit, gently twist it off with your hand, and pull it down.

Do not hurt the fruit, cloudy days.

Just do it. This reduces ineffective nutrient consumption, concentrates nutrients**, and provides what the fruit needs to grow and develop, so that the fruit expands quickly and fully.

Applying potassium fertilizer, pineapple is a high potassium fruit tree, potassium fertilizer is sufficient during the fruit expansion period, not only the fruit is large, but also the sugar content is high, sweet, the aroma is pure, the quality is good, and it is resistant to storage and transportation. Therefore, after the pineapple blooms, apply potassium fertilizer once, potassium chloride.

or 80-100 grams of potassium sulfate, sprayed after rain or sprayed with boiling water. Pest control, after pineapple flowering, it is necessary to prevent and prevent leaf spot, black rich disease, anthracnose, and heart failure.

Mites, mites, red spiders.

Every 10-15 days, 1000 times of farmland**, 800 times of methyl tophin mixture, 2-3 sprays in a row, wet leaves and fruits.

Bonsai fertilizer, combined with pest control, sprays elements and potassium dihydrogen phosphate in the liquid at the same time each time.

When 1000 times naphthalene acetic acid or 920 mixture, the fruit is fully expanded, satiety, peel, pulp, golden yellow, high sweetness, crisp flesh, good quality. It is advisable to plant pineapple flowers on mixed soils such as peat and cinders, keeping the growing environment between 20 and 35, and placing them in a position when ventilation is difficult. Watering once every 7 days, autumn rain, winter and flowering, do not store water in the leaf pond, and prune the flower stalk in time after flowering.

Pineapple flower propagation method, suitable soil. Pineapple flowers, also known as bromeliads, are more demanding on the soil. In general, it is possible to choose a mix of well-ventilated peat soils.

Raw soil, cinder, perlite.

Equal proportion of soil for planting, you can also buy pineapple flower special nutrient soil directly in the market.

Carry out planting. Proper temperature and light regulation is very important. The temperature suitable for the growth of pineapple flowers is between 20 and 35, and when it is lower than 10, the seat should be changed in time or heat preservation measures should be taken.

Pick the crown buds: About 20 days after the pineapple blooms, remove the crown buds on the top of the pineapple fruit, gently twist it down with your hand, do not hurt the fruit, and do it on a cloudy day. In this way, it can reduce the consumption of ineffective nutrients, concentrate the nutrients ** fruit growth and development needs, and make the fruit expand quickly and quickly.

It is necessary to pay attention to fertilization, but also to prevent pests during the flowering period, to watering, and to the management techniques of pineapples.

After the pineapple blooms, the fruit expands rapidly, and the crown buds must be removed in time, and the fertilization management and pest control work must be strengthened, and leaf fertilizer sprayed to promote the fruit expansion and prevent pests and diseases, so as to increase the yield and improve the quality.

How to survive the winter of pineapple, pineapple is one of the tropical fruits, and the sweet taste is deeply loved by people. Pineapple is rich in vitamins and minerals, which can supplement the nutrients needed by the human body and effectively promote human health. So how do pineapples survive the winter?

Let me share it with you.

1. How to survive the winter with pineapple seedlings

Pineapple seedlings have the worst cold tolerance, below 6 degrees Celsius will occur chilling injury, stop growing, such as cold will make pineapple seedlings lose their green, dry up, the most suitable temperature for cultivation is 20 30 degrees Celsius, to maintain 12 hours of light every day, stable temperature is conducive to the growth of pineapple seedlings, people with conditions can add light equipment at home, so that pineapple seedlings can thrive.

2. How to survive the winter of pineapple trees

The cold hardiness of pineapple trees is stronger than that of pineapple seedlings, the temperature of pineapple trees planted on land in winter is controlled between 6 and 10 degrees, and it can grow well on the warm shed, pineapple trees grow on land do not need watering, natural rain is enough, and pineapple trees are in the dormant period in winter, and they do not need to fertilize it, let it grow freely.

3. How to survive the winter with pineapple bonsai

Pineapple bonsai is not cold-tolerant, it must be placed indoors during the winter, and the indoor control can be above 10 degrees, and when the sun is full in winter, it is necessary to supplement the light and let the plants photosynthesize. Watering every half month in winter, it is best to choose to water at noon, no fertilization is required.

The minimum temperature for pineapples to survive the winter is 6 degrees

The minimum temperature of pineapple in winter is 6 degrees, below 6 degrees Celsius, the leaves will be yellow, lose green, and will die when the frost is severe. Although the pineapple is a hot fruit, the maximum temperature should not exceed 43 degrees, and too much heat will stop the pineapple from growing. Pineapples can be grown at temperatures ranging from 15 to 40 degrees, but they are best suited for it.

The growing temperature is between 24 degrees and 27 degrees.

1. Pay attention to temperature control

In order to prevent pineapple frostbite, it is advisable to control the temperature above 10 degrees, and if possible, it can be controlled between 15 degrees and 20 degrees.

2. Carry out reasonable lighting

Light is the best way to keep pineapples safe from the cold, put pineapples on the balcony at 10 o'clock every day for light, and put them back indoors at 4 o'clock, and do a good job of indoor temperature control.

3. Reasonable watering

For home potted pineapples, watering is very important, once every half a month in winter, do not choose to water in the morning and evening, the most suitable is noon, you can water it along the edge of the pot.

1. Planting time

The pineapple planting time should be determined according to the local climate, the south is generally in April to August each year, and the north is in March to September every year, and the use of the crown buds and descendant buds of the two fruits, as well as the buds collected when the garden is cleared for planting, can effectively improve the probability of sprouts taking root.

2. Seed treatment

Pineapple planting should select robust, disease-free seedlings, and then remove the yellow leaves and dead leaves at the bottom of the seedlings by hand before liquid, exposing the root point of the seedlings, so that the plants can quickly take root, if planted with buds, the bottom of the fruit tumor needs to be removed, and the roots are exposed before planting.

3. Planting code method

Pineapple planting in the soil can not be too deep, easy to make the soil splash into the heart of the plant, affect the subsequent growth of the plant, resulting in root and seedling rot, you can control the planting depth at about 3-4 cm, fill the gap by hand and compact, and water the soil, so that the soil and the roots and seedlings are closely attached, which is conducive to rapid rooting.

4. Soil requirements

Pineapple likes fertile, loose and breathable soil, which needs to be rich in organic matter, and can be mixed with peat soil, garden soil and perlite to make cultivation soil to promote the rapid growth of plants, and avoid using neutral and alkaline soil, which will affect the absorption of nutrients and water by plants.

When managing, we should pay attention to controlling the distance between them, and try to increase them as much as possible to ensure that all roots and seedlings can absorb the exposure of sunlight, and they should be watered more, and proper soil turning can also improve yield.

It should be planted in an area with a more suitable temperature, and attention should be paid to the scientific and technical management methods of jackfruit, and at the same time, attention should be paid to fertilization management.

Care should be taken to plant in spring (March to April) and autumn (September to November), which is the best climatic environment, and to manage it is important to remember to deal with weeds, prune unnecessary branches and leaves, etc.

First, the jackfruit is planted in the greenhouse, and the plant nutrient solution is cultivated, and then transplanted outside after they are alive.

When potted pineapples are being maintained in winter, care should be taken to regulate the temperature, pay attention to windproofing, ensure adequate light, and carry out proper water control. The temperature should be above 5. Ground plants should be covered with windproof warmth, ensuring they have adequate daily light hours and proper water control to prevent water from freezing.

Winter maintenance method for potted pineapples.

1.Thermostat. When maintaining potted pineapples in winter, the most important thing is to control the temperature. Pineapple is a plant that lives in the tropics, and as such, freezes easily in winter. It needs to be moved to a warm room.

The temperature should be above 18 and at least not lower than 5. When moving indoors in winter, it should be regularly exposed to full sunlight to ensure photosynthesis, promote growth, and prevent low-temperature frostbite. If you can't move indoors, at least cover it with plastic wrap to protect it from the wind and cold.

2.Pay attention to windproofing.

If you have a garden or yard, pineapples can also be buried in the soil along with potting soil for potting, and add some fertilizer to the soil appropriately to increase the ground temperature of the soil where the pineapple potting is located, and then wrap it with warm materials such as straw to keep warm from the wind.

3.Guaranteed light.

The light intensity is relatively weak in winter, and the pineapple itself is a light-loving plant. Therefore, it is necessary to provide it with enough light. The amount of light you spend each day is usually about a quarter longer than in spring and autumn.

If the light is low, it can receive light throughout the day, especially indoor potted plants.

4.Proper water control.

Pineapples are drought tolerant, and in winter, due to the relatively low ambient temperature, pineapples will also grow and develop at a slower rate and absorb less water. Therefore, the amount of water should be reduced when watering, and the moisture should be properly controlled to avoid freezing or rotting of its roots.

5. Water and fertilizer control: In order to survive the winter safely, you can not blindly water and fertilize in winter. You can water the soil every half month, but you don't need to fertilize it.

6.Proper pruning: Cut off all the dry old and diseased leaves of the pineapple before it gradually cools down in winter to ensure the concentration of soil nutrients and avoid frostbite on the roots.

It should be placed in a sunny place, on the balcony during the day, and indoors at night.

Potted pineapples can be moved back indoors in winter to keep warm, and the indoor temperature is generally higher than outdoors in winter, so moving the potted plants back indoors can effectively keep warm, but care should be taken to avoid potted plants being close to heat sources.

Hello, the management of pineapple fruiting recommends that you must apply heavy fertilizer after picking the fruit, because the bud growth of the mother plant requires more nutrients. Mainly apply fast-acting liquid fertilizer, 1000 kg of urea mixed with water 5 kg per mu, or 1500 kg of dilute human feces, apply into the base leaf axil, after fruit picking, cut off the old leaves of Jingxiaoxiao on both sides of the furrow, so that the young shoots can make full use of the sun, brighten the bridge to speed up the growth, and improve the disease resistance. The cut old leaves are covered on the furrow surface or between the rows, which can play a role in heat preservation and drought prevention.
