How to reproduce pineapple? when is the best time to sow pineapple / sowing in April?

Pineapple is a fast-growing plant, which is often cultivated as an annual plant, so after planting for a period of time, florists need to consider reproduction. Pineapple is also very characteristic in reproduction, it can reproduce through self-sowing, but family breeding generally needs artificial cultivation, so how to reproduce pineapple? Let's take a look at the breeding method of pineapple.

How does pineapple reproduce?

Wild pineapple will be self-sowing, but artificially cultivated pineapple will generally use two propagation methods, namely sowing and cutting, in which sowing is more common, but we must pay attention to skills when sowing, such as seed collection, time selection, and so on. Let's take a look at the specific operation methods.

Sowing and propagation of pineapple

1. When will pineapple be sown

The editor suggests that we sow seeds in April every year, because it is easy for seeds to take root at this time, but seeds are not collected in April, but are picked along with ripening, because the ripening time of its fruit is different, and it is easy to fall off after ripening, so pay attention to observe the ripening time and collect it as soon as it is ripe.

2. Sowing method of pineapple

⑴, how to reproduce pineapple when sowing? Generally use a seedling tray to sow seeds, sow collected pineapple seeds on the seedbed, then cover 1-2 cm thick fine soil, soak from the bottom of the basin, keep the temperature between 20-25 degrees, and then emerge 4-7 days later.

⑵ needs to be cultivated for a period of time after emergence, and it generally takes 45 days to wait for it to grow new branches for transplanting. After transplanting, maintenance and management should be carried out according to the planting method of pineapple, and attention should be paid to avoid entanglement of vines during the period of seedling cultivation, and to ensure that the soil is moist and not dry, otherwise the seedlings are easy to die.

3. Points for attention

When selecting seedlings, we must pay attention to planting red and white separately, because pineapple flowers have both white and red, need to collect seeds separately and sow separately, must not be mixed together, otherwise it is easy to cause sowing failure.

Cuttage propagation of pineapple

1. Can pineapple be cut

Cutting is a common way of propagation when planting a lot of plants. Because pineapple is an annual plant, can pineapple be cut? At present, some flower friends think that it can be cut, but some botanists think that it can only be propagated by sowing, so there is some controversy. Let's share the methods of flower friends who have tried cutting.

2. How to cut pineapple

Generally, cuttings are carried out in early spring, and the more robust branches on the plant are used as cuttings. When making cuttings, cut the branches into 5-15 cm long segments, retain more than 3 leaf nodes, the lower cut should be flat, and then leave it in a cool place to dry.

The cuttings are cut in the prepared substrate, which is made of a mixture of culture soil and fine sand, compacted and poured through water, ensuring that the temperature is 20-30 degrees Celsius, putting it in a cool place, spraying properly when the temperature is high, and ensuring that the humidity is about 75%. It can take root after a period of time.

Propagation method and planting of pineapple when to sow pineapple

Pineapple originated from Mexico, also known as Milosong, commonly known as pentagram flower, liongrass, introduced into England in 1629, and later introduced into China. The propagation methods of pineapple include sowing propagation, cuttage propagation and striping propagation. When will pineapple be sown by sowing and breeding? Next, let's learn about the relevant information.

The introduction of pineapple

Pineapple, native to Mexico, is also known as Miloson, commonly known as pentagram flower and lion grass. The Book of songs says, "if you give it to the pines and cypresses, it means that brothers and relatives are dependent on each other." Both of them are parasitic on pines and cypresses. The shape of the pineapple is quite similar to that of the female pineapple, so it is named after the pineapple pine (almanac, botanical dictionary), feathered pineapple, Jinpingfeng (map of higher plants in China), golden thread (Guangxi), dragon grass, and dragon flowers.) The florescence is long, from April to November every year in China, Anhui, Hubei and Hunan. The demand for soil fertilizer is not high, sowing seeds on wet soil can germinate, and the germination rate is more than 95%.

1. Morphological characteristics

Summary: pineapple is an annual weak twining herb, glabrous.

Leaves: leaves of pineapple ovate or oblong, 2 × 10 cm long and 1 × 6 cm wide, simple leaves alternate, leaf lobes slender as silk, pinnately parted to midrib, with 10-18 pairs of linear to filiform spreading lobes, lobe apex acute; petiole 8-40 mm long, base often with pseudostipules.

Flowers: inflorescences of pineapple axillary, made up of Cymes of a few flowers; total pedicel mostly exceeding leaves, 1.5 × 10 cm long, flowers erect, pedicel longer than calyx, 9 × 20 mm long, thickened into a stick when fruiting; sepals green, slightly unequal, elliptic to oblong spoon-shaped, outside 1 slightly shorter, ca. 5 mm, apex obtuse and small convex. Corolla salverform, ca. 2.5 cm long, crimson, glabrous, tube weak, distally slightly inflated, limb spreading, ca. 1.7 × 2 cm in diam., 5-lobed; stamens and style protruding; filament base hairy; ovary glabrous. On several pentagonal star-shaped flowers, the color is deep red and bright, in addition to red, there are white.

The flowering period of pineapple is from early July to late September. One batch of pineapple opens every day and wilts in the morning and afternoon.

Fruit: pineapple capsule ovate, 7 × 8 mm long, 4-loculed, 4-valved, septum persistent, transparent. Seeds 4, ovate-oblong, 5-6 mm long, dark brown. The slender, smooth trailing stem of pineapple, which can be up to 4cm long, is soft and full of climbing, making it an ideal hedge plant. The ripening period of pineapple is from September to November.

2. Ecological habits

Pineapple likes light, likes warm and humid environment, grows in an area of 0 to 2500 meters above sea level, is not cold-resistant, can self-sow (usually introduced by artificial cultivation), and requires fertile soil.

Pineapple has strong resistance and easy management. The capsule contains 4 seeds, which, after maturity, falls to the ground and grows in the following year. If sown artificially, it will be sown in March. The seedlings were transplanted with a length of 10 cm. In order to bloom more, it should be planted in the fertile soil in the sunny place. Potted plants should stand on brackets for winding, and they are extremely slender and beautiful when they bloom.

When will the pineapple be sown?

It was introduced into England in 1629 and then into China. Pineapple should be propagated with seeds. Sowing in early April, after sowing, you should pay attention to shade, keep the seedbed moist, and seedlings can emerge after about a week.

First, the cultivation of pineapple is relatively simple:

1. Open field planting

It is appropriate to select places with leeward and sunny direction and good drainage. In addition to applying base fertilizer, liquid fertilizer should be applied twice before flowering. When planting, be sure to water thoroughly, and then only need to water once a week. (note that pineapple is not suitable for transplanting after it has grown into a big seedling.)

2. Potted pineapple

When putting on the basin, a little base fertilizer should be put into the bottom of the basin, and then liquid fertilizer should be applied once a month. Water at the right time, but do not accumulate water.

3. Thinning vines and leaves properly

It is not only conducive to ventilation and light transmission, but also make the plant shape beautiful. After the flower fades, the residual flowers should be picked in time to prevent it from bearing seeds, so that nutrients can be concentrated for new branches to blossom and prolong the flowering period.

Because pineapple is native to the tropics, it likes warmth, avoids cold, is afraid of frost, and grows very slowly when the temperature is low. The suitable temperature for seed germination is 20-25 ℃. In sunny environments, most species are not strict about the number of hours of sunshine, but Quamoclit lobata needs less than 12 hours of sunshine before it blossoms. It is not strict with the soil, but it grows well on the rich and loose soil.

The seed weight of a thousand seeds is about 139, and the seed can be used for 3 to 4 years. The ripening period of the fruit is inconsistent, and it is easy to fall off after ripening, so it should be picked with ripening. Each fruit contains 3-4 seeds. If there are both red and white flowers, seeds should be collected separately.

The method of propagation of pineapple

1. Sowing and reproduction

Spring seedlings in the protected field, after the final frost planting in the open field for about 45 days, not too long, otherwise the vines of the seedlings will be intertwined.

The seedlings can grow well by sowing and cultivating seedlings with ordinary nutritious soil. Sow seeds on a seedling tray. The seeding rate per square meter is about 100g, and the fine soil 1.5cm is covered after sowing. It should not be too thin, otherwise it is easy to be unearthed with seed coat. The ground temperature was controlled at 20-25 ℃, and the seeds were dried for 4 days to emerge. The seedlings of pinnacle and maple are shown in figure 7. Pineapple seedlings are easy to emerge, but they are often irregular, so they should be carefully selected so that the seedlings are neat. The author observes that pineapple seedlings are very afraid of drought and will die when the drought is slightly severe, and it is difficult to recover even if watering, which should be paid special attention to when raising seedlings. Because it is a straight-root plant, it is best to grow seedlings in a plastic seedling bowl with a diameter of 8cm, and the seedlings are moved only once, and one seedling is planted in each container. It can also be cultivated into seedlings with 72-hole hole trays, and attention should be paid to the supply of water during the period of cultivation. The soil moisture was moderately controlled in the middle and later stage of seedling cultivation. Full light should always be seen at the seedling stage. If the seedlings are large and the vines are intertwined, they should be separated as soon as possible, and the seedling bowl should be moved away at a certain distance if necessary.

Red flowers are more gorgeous than white flowers, and most people prefer red flowers. But even if all the red flower seeds are harvested, most of the offspring may separate white flowers. Seeds are not easy to distinguish, but they are easy to distinguish at seedling stage. The stem color of red flowers is dark red, while the stem color of white flowers is green, which can be well distinguished by careful observation. If the seeds are carefully selected every year, and pay attention to isolation, the offspring will be less and less mixed.

Cultivation management: planting after the final frost, in areas where the night temperature is still relatively low, generally speaking, early planting is not recommended. Pineapple has strong self-sowing ability, and self-sowing seedlings can also be used in the second year of cultivation if it does not care about the time of flowering, but because there is no seed selection and emergence late, the greening effect is poor. Pineapple has a large growth, so it should be fully fertilized, spread evenly and turn deeply. Planing hole planting, remove the plastic seedling bowl, plant the seedling in the hole, 1 plant in each hole, cover the seedling tuo with fine soil, then water, cover the soil to seal the hole. The plant spacing of single-row planting is about 35cm, the plant spacing of seedling cultivation or fertile soil should be larger, and the self-sowing seedling emergence is late, the growth is delayed, and the plant spacing should be smaller. Timely watering can promote the growth of stems and leaves, but be careful not to grow too much so as not to delay flowering. In the early stage, artificial assistance is introduced to scaffolding, fences, trees or other supports. In the middle and later period, the plant itself has a strong climbing ability, in addition to modeling, do not care about it, let it climb and winding. Potted plants should be watered and fertilized frequently. It can also be planted indoors in winter, but we should pay attention to room temperature, light and other conditions.)

In northern families, pineapple can also be cultivated in winter. After heating at home, the "tissue culture" (also known as seedling promotion) is used to promote pineapple seed germination in a short period of time. When the seeds show buds, sprinkle them into a flowerpot and attach 1~1.5cm soil to ensure the growth of pineapple. After a week or so, pineapple will take root and sprout, so pineapple seedlings must be treated with caution. Due to the lack of light in winter, it is necessary to manually select a place with sufficient light to cultivate pineapple, it is recommended to put it in the house facing south, and the flowerpot should be placed closer to the heating to ensure a suitable temperature.

2. Cuttage propagation

It is often used for softwood cutting in late spring and early autumn, or old wood cuttings with branches from last year in early spring.

When the tender wood cuttings were carried out, the sturdy branches of the current year were selected as cuttings when the plants were growing vigorously from the end of spring to early autumn. After cutting off the branches, select the sturdy parts and cut them into segments 5-15 cm long, each with more than 3 leaf nodes. When cutting cuttings, it should be noted that the upper cut is cut flat at about 1 cm above the uppermost leaf node, and the lower cut is about 0.5 cm below the lowest leaf node, and the upper and lower cut should be flat (knife should be sharp). When hardwood cuttings are carried out, after the temperature rises in early spring, last year's robust branches are selected as cuttings. Each cuttage usually retains 3-4 nodes, and the cutting method is the same as that of softwood cuttings. Reasonable management after cuttage

Temperature: the optimum temperature for rooting of cuttings is 20: 30 ℃, which is lower than 20 ℃, and it is difficult and slow for cuttings to take root. When the temperature is higher than 30 ℃, the upper and lower cuttings of cuttings are susceptible to bacterial infection and rot, and the higher the temperature is, the greater the proportion of rot is. When there is a low temperature after cutting, the heat preservation measure is mainly to wrap the flowerpot or container used for cutting with thin film; when the temperature is too high after cutting, the cooling measure is mainly to shade the cuttings, to cover 50-80% of the sun, and at the same time, spray the cuttings 3-5 times a day, with more times of spraying when the temperature is higher in sunny days, lower temperatures and higher temperatures in rainy days, but less or no spraying times.

Humidity: the relative humidity of the air must be kept at 750.85% after cutting. The basic requirement for cuttings to take root is to ensure that cuttings are fresh and tender and can be used to produce rooting substances before they take root. However, cuttings without rooting can not absorb enough water to maintain their water balance, so it is necessary to reduce the water evaporation of cuttings by spraying: under shaded conditions, the cuttings are sprayed 3-5 times a day. The higher the temperature in sunny days, the more the times of spraying, the lower the temperature in cloudy and rainy days, the less or no spraying. But with excessive spraying, cuttings are easy to be infected by bacteria and rot, because many kinds of bacteria exist in the water.

3. Striping propagation

Select a strong branch and peel off the bark from about 15cm to 30cm below the top. The width of the peeled wound is about one centimeter, and the depth is limited to just peeling off the skin. Cut a piece of film 10 cm 20 cm long and 5 cm 8 cm wide, put some wet garden soil on it, and wrap it around like a wound. The upper and lower ends of the film are tightly tied and bulged in the middle. Take root in about four to six weeks. After taking root, cut off the root system along the edge of the branch to form a new plant.

Sowing method and time propagation method of pineapple

Pineapple is a kind of herb, the flowers are crimson, there will be white, from a distance, like a small red trumpet, take a closer look, the flowers are red pentagram, bright, all there are many places called pentagram flowers. So do you know how to plant pineapple? Let's go with the editor to learn about the planting method of pineapple.

Sowing method and time of pineapple

Sowing time of pineapple: pineapple is suitable for sowing in early spring from March to April, early in the south and postponed for a period of time in the north.

The method of sowing pineapple: pineapple can be direct seeded in the open field or sown in a shallow pot. The seedlings grow and are pulled by string to make all kinds of bonsai with flower racks. Sow 5-7 seeds in the basin, cover about 0.5 cm of soil, keep the soil moist, and grow seedlings in about 10 days. after half a month, the seedlings are weak and strong, and 3-4 pineapple seedlings are retained. Seedling height 8-10 cm coring, promoting multiple branches and multiple flowering.

Propagation method of pineapple

1. Sowing and reproduction

The emergence of pineapple is easy, and artificial sowing is also very simple. In spring, sowing and raising seedlings, the flower seedlings of pineapple should be transplanted and cultivated when they grow to the right stool.

First of all, sow seeds on a seedling tray. Sprinkle pineapple seeds on the seedbed and cover it with a layer of fine soil. The temperature of seed germination is between 20 and 25 ℃. If the temperature is maintained, the seedlings can emerge 4 days after sowing, and continue to grow for a period of time after emergence. The seedlings can be transplanted in about 45 days. It should be noted that the vines of the seedlings should not be intertwined.

The seedlings of pineapple should be well watered when they are cultivated. They should not be dry. Once they die, they cannot be remedied. In the seedling stage, it is necessary to ensure sufficient light and keep a certain distance between the seedlings in order to grow vigorously.

One thing to pay attention to is the seedling selection of pineapple. Because pineapple has red and white, most people prefer red because of the bright color of red pineapple. Be careful when planting to avoid mixed colors in future generations. In general, the seedlings of pineapple, the stems of seedlings with red flowers are dark red, and the stems of seedlings with white flowers are green, which is easy to distinguish.

2. Striping propagation

Striping is a common method of flower reproduction. When making strips to propagate pineapple, select the sturdy branches of pineapple, select a section of 15 to 30 centimeters, and remove the peel of the branches in the right position. Wrap a piece of film with a length of 10 cm to 20 cm and a width of 5 cm to 8 cm, and wrap it up like a wound to cover the peeled part of the pineapple, allowing it to take root. It can take root in four to six weeks. After taking root, cut off the branch and the growing root system together to form a new plant. It's ready to plant.

Matters needing attention in the culture of pineapple

Although this plant likes to be wet and is not tolerant to drought, it is also afraid of waterlogging, so it cannot accumulate water. Even at the peak of evaporation in summer, do not water too much to soak the roots of the soil in water.

In the summer high temperature season, in order to replenish enough water, in addition to the appropriate increase in the amount of water, you can also replenish water by humidifying the air or spraying wet leaves. Even in winter, you can sprinkle some water on the leaves to make them look cleaner.

In the rainy season, if the plants are left outdoors, drainage should be done in time.

The growth habits of pineapple

Pineapple likes sunshine and is suitable for growing in a warm and humid environment. It is not cold-resistant and can sow itself. It is not strict with the soil, but when cultivated in fertile soil, the flowers are brighter and the stems and leaves are more luxuriant. Strong growth, usually management, can be more extensive. You can sow and reproduce.

Pineapple looks soft and weak and usually grows with twining. The branches are slender, the leaves are ovate, and the lobes of the leaves are as slender as silk and feathery. The flowers are small, five-pointed star-shaped, dark red in color, just like dots and have a unique flavor. The flowers will bear seeds when they bloom.

As mentioned above, pineapple is a very beautiful flower plant, not only beautiful flowers, bright colors, but also its florescence is very long, deeply loved and sought after by everyone. Do you like beautiful pineapple?
