How long does it take for pineapple flowers to bloom? How long does it take for pineapples to be pla

Temperature is the most important ecological factor affecting the growth, yield and quality of pineapple. According to research, pineapple can grow in 15 40, 28 32 is the most suitable, 10 slow or stop growing, continue to be less than 5 that is cold damage, 1 2 stay 1 2 days can survive, too long is serious damage. Compared with other tropical herbaceous fruit trees (e.g. banana and papaya), pineapple has a strong tolerance for low temperatures and brief frosts.

Different pineapple varieties react differently to temperature when the average temperature of the day is around 13 and only begin to bloom at 16 o'clock. Drought and heat can also inhibit flower blooming or cause incomplete flowering. The length of the fruit ripening period and the quality of the fruit are also closely related to the temperature.

The average temperature from budding to maturity increased by 1, and the number of days at maturity decreased by about 5 8 days. If the temperature is high, the sunshine is strong, and the moisture is sufficient, the ripening period is short and the quality is good. Therefore, summer and autumn fruits generally have a shorter ripening period than winter and spring fruits, and the flavor is good.

Pineapples are a relatively drought-tolerant crop. According to research, the evapotranspiration of pineapple is about millimeters per day, even if the original water content of the soil is relatively high, as long as there is no precipitation for 3 or 4 weeks, the water in the soil can be exhausted, so the proper water should be paid attention to in the growth and development of pineapple, in order to ensure its normal growth and development. However, pineapple is a shallow-rooted aerated crop, too much water, too much soil moisture, will cause poor soil aeration, hinder nutrient absorption and utilization, and seriously cause root rot and death.

It has been reported that pineapples are more suitable for growing in places with annual rainfall of more than 1000 to 1500 mm and a relatively uniform distribution of precipitation time (monthly rainfall of 100 mm). The water table of 30-50 cm is conducive to root growth. The short-term drought in autumn and winter is conducive to the differentiation of flower buds and the enhancement of the cold resistance of plants, but excessive drought will cause the plants to become yellow, the fruit stalk will dry up, and the core of the fruit will crack, which will also lead to early maturity, small fruit, not full, light flesh color, less moisture, poor flavor, and induce wilt, which can reduce the yield by about 20%.

If the low temperature and drought in winter and spring are long, it will lead to the reduction of cold resistance of plants, which is not conducive to flower bud differentiation, poor flower bud development, and even stagnation. Therefore, when the monthly rainfall is less than 50 mm, irrigation is required to replenish water.

Guangdong April September is the rainy season, there are often heavy rains, often due to poor drainage caused by floods, mountainous areas are prone to cause serious soil erosion, therefore, should do a good job in the construction of pineapple orchard drainage and irrigation projects, pay attention to do a good job of water storage and soil and water conservation work.

Although pineapples originally grew in the semi-shady environment of tropical rainforests, they are sensitive to light requirements after long-term artificial domestication. The intensity and amount of light directly affect its growth and development, yield formation and quality. Proper light can increase yield and improve quality and flavor; Insufficient light, the leaves become elongated, the fruit is small, and the fruiting rate is low.

A 20% reduction in natural light has been reported to reduce the yield of spiny-free pineapple seeds by 10%. Pineapple likes diffuse light, afraid of direct strong light, high temperature and strong light in summer, will make the leaves turn red and yellow, young buds and fruits are also easy to be damaged by sunburn, which can reduce the yield by 3 5%, so shade and sun protection measures should be taken.

Ornamental pineapple (hereinafter referred to as pineapple) is commonly known as pineapple flower or pineapple flower, its plant is graceful, the color of the flower is bright and bright, and the viewing time is long, and it is quite popular in the market in recent years.

In their natural state, pineapples bloom naturally when they have a sufficient number of leaves, are of the right age, or are exposed to low temperatures. In large-scale greenhouse production, it is necessary to formulate a detailed production plan and do a good job in promoting flowering, so that pineapples can bloom during the hot market period. 1.

Preparation before flowering, some preparations need to be made before flowering, so that pineapples become sensitive to "flowering" to achieve the ideal flowering effect. First, switch to a high-potassium and low-nitrogen mixed fertilizer; Secondly, 3 weeks before flowering, stop applying any fertilizer and only water water; In addition, when officially promoting flowering, the stagnant water in the pineapple leaf cup needs to be emptied. 2.

The most commonly used method of flowering is to use acetylene saturated solution for flowering. This method can be used for all ornamental pineapples except for the genus Tielan. How to deal with it:

First, a bottle containing acetylene gas is connected to a conduit with a "stomatal stone", and then the acetylene gas is slowly released into the water with Pa's pressure. Pay attention to the pressure should be appropriate, too low pressure will prolong the dissolution time, too much pressure may cause calcium carbide to escape. At the same time, the acetylene gas in the bottle should not be used too cleanly, too clean will also cause calcium carbide to escape.

Calcium carbide can damage pineapple leaves, causing brown spots on the leaves, causing them to swell. 200 litres of water can be aerated for at least 2 hours to reach saturation, at which point there will be a strong smell in the water. Secondly, connect one end of the watering pipe to the self-priming pump and put it into a container filled with acetylene saturated solution, and the dosage should be just filled with leaf cups.

The pressure of the self-priming pump is larger during operation, and the water flow and water pressure can be adjusted by installing a plurality of water outlets at the self-priming pump pipe position, and the number of watering pipes can also be set according to the need. Remember: In the process of flowering, be sure to keep the container and watering pipe clean and clean, if there is residual fertilizer, liquid, etc., it will affect the effect of flowering.

Do not close the acetylene gas valve while promoting flowers, because acetylene gas is easy to evaporate from water, if you close the gas valve, the acetylene concentration in the water will gradually decrease, affecting the effect of flower promotion. Flowering is generally repeated 3 times, with an interval of 2 to 3 days each time, the flowering temperature should be controlled at about 20, and the light should not be too strong, so it is best to do it in the morning. After the flowering is over, only water is watered for 3 weeks.

After the start of fertilization, potassium fertilizer should be more on the side, and the light can be slightly strengthened, which is good for the coloring of pineapples, and can avoid dull flower color and uneven coloring. The time it takes from the end of flowering to the emergence of pineapples varies depending on the variety, ranging from 3 to 6 months.

It usually takes 2 years to grow, and it can bloom after 30-40 leaves. However, pineapples do not bloom easily, and sometimes they need to be urged to bloom.

Temperature has a great impact on pineapple flowering, pineapple varieties are different, its flowering response to temperature is different, the average temperature is about 13 will not bloom, generally 16 o'clock before the beginning of flowering. Drought and heat inhibit pineapple blooming or cause flowering to be missing.

Pineapples are planted using sucking sprouts (i.e., new seedlings growing from pineapple roots), and if managed well, the fruits can be harvested in about 14 months.

Pineapple blooms from January to February and bears fruit from April to May, blooms from March to April and bears fruit from June to July, blooms from July to August and bears fruit from October to November, and blooms from September to October when the finch matures between December and January of the following year.

1. Time

Pineapples generally have four harvesting seasons, spring fruits bloom in January and February, and bear fruit in April and May, and are also known as summer fruits, which bloom in March and April and bear fruit in June-July, and autumn fruits bloom in July and August and bear fruit in October-November, and winter fruits bloom in September and October, and can only bear fruit and ripen between December and January of the following year, and this time is not completely fixed.

2. Plant characteristics

Pineapple belongs to one of the representative plants of the bromeliad family bromeliads, is a perennial herbaceous fruit tree plant, generally planted as a cash crop, its growth rate is extremely fast and the production cycle is relatively short, under the right conditions can grow and develop and flower and bear fruit throughout the year, any time period may bear fruit.

3. Temperature conditions

Pineapple is a typical tropical plant, only in a warmer environment can grow and develop and flower and bear fruit, so during its growth and development, to stabilize its surrounding environmental temperature at about 20 degrees Celsius, flowering and fruiting period is best to ensure that between 22-25 degrees Celsius, the temperature difference between day and night is not too large to lead Qi dust.

4. Precautions

Pineapple is a plant that can bloom and bear fruit all year round, but it does not bear fruit until it is not old, and it usually takes about 3-4 years to produce fruit after planting, and it can bloom in the second year of growth, but it does not bear fruit until the third year of the next year.

Homegrown pineapples generally bloom in 2-3 years. After planting, if the maintenance conditions are suitable, the pineapple can flower and bear fruit in 1 year at the earliest, but it is generally about 2-3 years, and the maintenance will be delayed if it is not good, so as to ensure sufficient water and fertilizer**, sufficient light, and stable temperature can flower and bear fruit as scheduled.

- About 3 years

It takes about 2-3 years for pineapples to bloom from the beginning of planting, and the growth and development of pineapples is relatively fast, if they are well maintained and the surrounding environment is very suitable, they actually only need 1 year to bloom, but they usually need to wait until 2-3 years to bloom and bear fruit.

2. Light control

If you want to make the pineapple bloom and bear fruit as scheduled, it is necessary to have enough light time, and after receiving sufficient light, the pineapple can convert nutrients into nutrients, and then promote the flowers to start to grow and bloom, so it is impossible to bloom in a dark environment for a long time.

3. Temperature control

If the pineapple wants to bloom, it is also important to control the temperature. Pineapple is a plant that grows healthier in a warmer environment, so the ambient temperature around it should not fall below 15 degrees Celsius at the lowest time, otherwise the growth rate of the plant will decrease significantly.

4. Water and fertilizer**

With sufficient water and fertilizer, pineapple has the ability to flower and bear fruit, otherwise if it is not watered for a long time and does not top dress, the plant will enter a state of growth and development even if it does not dry up, and even maintaining life in this state is a big problem, and it is impossible to flower and bear fruit, so watering and fertilization should be moderate and appropriate.

1. Pineapple can bloom four times a year, and the flowering time is January-February, March-April, July-August and September-October, so its ripening time is April-May, June-July, October-November and December to January of the following year. Pineapples are best planted in autumn because seedling pineapples need sunlight, but they are afraid of strong sunlight, and the autumn sun is just right. It has a long growth cycle, generally taking 2-3 years to flower and bear fruit.

2. Before flowering, the center of the top leaf of the pineapple slowly turns red, and a reddish-brown inflorescence grows, shaped like a pine ball, about 8 cm long, the petals are oval shaped, the top is purple-red, the bottom is white, and the flowering period is long, which can last from summer to winter. Pineapples bloom once a year and die when they bloom.

3. After the end of the flowering period, the flowers begin to dry and turn red, the inflorescence gradually expands, becomes a fruit, the top grows overlapping new leaves, the top of the leaf is red, the bottom is green, the pineapple fruit is green at the beginning, and then begins to ripen slowly and becomes yellow, and the fully ripe fruit is dark yellow to orange, beautiful in appearance and rich in fragrance.

Pineapples bloom, ornamental pineapples can last from summer to winter, but they only bloom once in their lives, they are pink or bright red, they die after the flowering period ends, and the temperature needs to be maintained at around 16 35 in order for them to bloom. And the plants that produce pineapples take 2 to 3 years from seedling to flowering to bloom for the first time.

Many people should wonder if pineapples bloom, in fact, they do bloom, the flower color is pink or bright red, and pineapples have a long flowering period, which can last from summer to winter. In order for it to bloom, the temperature needs to be maintained at around 16 35. However, many ornamental pineapples only bloom once in their lifetime, and the plant dies after the flowering period ends.

The plant used to produce pineapple needs to go through 2 to 3 years of maintenance from seedling to flowering, and during this period, it needs to be continuously supplemented with a lot of fertilizer and water, and its branches and leaves should be pruned regularly, and the weak branches, diseased branches, and dead branches will be cut off, so that the nutrients will be more concentrated and the rapid growth of the plant will be promoted.

After the pineapple blooms, the fruit will also expand rapidly, which will consume a lot of nutrients, and it needs to be supplemented with potassium fertilizer in time to make the flowers bloom more vividly and the fruit fuller. After the flowering period, it is necessary to add potassium fertilizer once, and about 80 grams of fertilizer per pineapple plant.

During this period, it is also necessary to control pests and diseases, especially leaf spot, black rot, anthracnose, scale insects, aphids and red spiders, etc., every 10 15 days spray 1000 times of nongdile and 800 times of methyl tobuzin mixture, spray 2 3 times in a row.

The flowering period of pineapple is generally about 18 months, and pineapple is also one of the tropical fruits, which is called Wang pear in Taiwan and Fujian, and yellow pear in Singapore and MalaysiaAnd there are more than 70 varieties. In fact, pineapples have their own special growth habits, and most pineapples have rosette-like leaf clusters. And there is a small leaf tube at the bottom that can store water, so that the water needed for the growth and development of pineapple will not be stored in the mesophyll, and it will generally be from it in the middle of the night.

The doctor should also water the leaf tube frequently so that the leaf tube has enough water so that the pineapple can thrive. At the same time, this is also a special habit of pineapples, many pineapples also have a special habit, that is, they can only bloom once in their lives, and the mother plant will die after flowering for a period of time. At the same time, pineapples like to be warm, and generally grow at an average of 24 to 27 years a year, and stop growing when planting.

The depth of planting is probably no more than 1 5 of the bud length, and the soil inside the pot must be kept at a dry temperature. <>

The soil is watered and the pineapple is very drought tolerant, but it also needs a lot of water to grow. It grows in areas with an annual rainfall of 500 to 2800 mm, and when the soil is short of water, the pineapple plants can self-regulate. It can reduce and slow down breathing and save reserve water, so as to maintain life movement.

And when there is a severe shortage of water, the leaves will be red and yellow, so you must irrigate in time to prevent the leaves from drying out. <>

When there is too much rainwater, the soil will be very moist and will cause the root system to rot gradually, so it is important to remember to drain the water in time after heavy rain or heavy rain. Therefore, it is also necessary to understand that pineapple is still very adaptable to the soil, but in the process of breeding, we must pay attention to looseness and grasp the amount of drainage. In this way, it is conducive to the better growth of pineapples and can also achieve the effect of high yield.
