Pineapple management cultivation technology, pineapple planting technology management

When planting pineapples, it is necessary to raise seedlings for them, the seeds can be sown into a seedling bowl equipped with substrate, and the ambient temperature is controlled between 24-26 degrees to promote the rapid emergence of pineapples, and when the pineapples grow 3-4 true leaves, they should be transplanted into the soil rich in organic matter, and weeds should be pulled out in time to make pineapples grow healthily.

1. Seedling raising method

The seeds of pineapples are small and not easy to germinate, when planting pineapples, they need to be seedled, and they can be mixed with river sand, perlite and peat soil to make a cultivation medium, and then the cultivation substrate is sterilized at high temperature, and then the pineapple seeds can be evenly sprinkled in the seedling bowl filled with the substrate.

2. Suitable temperature

When raising pineapple seedlings, you need to use plastic film or glass to cover the seedling bowl to moisturize and keep warm, and the ambient temperature should be controlled between 24-26 degrees, which is the best growth temperature for pineapples, wait for about 7-14 days, pineapples can germinate, at this time you need to water every other week.

3. Planting method

When planting pineapples, it is necessary to transplant them into loose and breathable sandy loam soil when the plant grows 3-4 true leaves, and to apply enough base fertilizer to the soil, you can choose well-rotted organic fertilizer, calcium, magnesium and phosphorus fertilizer, and remove the dry and rotten pineapple seedlings in time to make them grow healthily.

4. Maintenance management

When breeding pineapples, it is necessary to apply potassium chloride and urea once for the plants after they are planted and survived, so that the growth rate of pineapples is accelerated, and weeds should be pulled out every half a month, so as not to rob the nutrients of weeds and pineapples, and during the development of pineapple inflorescences, magnesium sulfate and sulfuric acid should be applied to them to make the plants bear fruit quickly.

<>1, garden finishing: deep ploughing deep ploughing 25-30cm, 1500kg of rotting chicken manure per mu, 50kg of calcium, magnesium and phosphorus fertilizer, and then leveling to make furrows, furrow width 140cm, furrow spacing planting: to plant in April to May each year is appropriate, plant spacing is about 35cm, row spacing is about 35cm, planting 2500 plants per mu, if planting crown buds, the depth is 3-4cm, if planting descendant buds, the depth is 6-7cm.

1. Garden tidying

1. Select sandy loam soil with a slope below 20°, deep soil layer and acidic layer for planting.

2. After selecting the planting plot, plough it deeply about 25-30cm, and apply 1500kg of rotted chicken manure and 50kg of calcium, magnesium and phosphorus fertilizer per mu.

3. Leveling and making furrows, the width of the furrow is 140cm, and the distance between the furrows is 100cm.

2. Colonization

1. Generally, planting is carried out in March to September every year, and it is advisable to plant in April and May each year.

2. The plant spacing is controlled at about 35cm, the row spacing is controlled at about 35cm, and 2500 plants are planted per mu.

3. Before planting, peel off 2-3 leaves at the base, and then soak the base with 25% carbendazim 800 times for about 10 minutes, dry and transplant. When planting, the depth is 3-4 cm if the crown bud is planted, and 6-7 cm if the bud is planted.

3. Management

1. After the plant survives, urea plus 1% potassium chloride leaching solution is used for 2-3 times of extra-root topdressing.

2. In the spring and autumn of the second year, fertilize once, and apply 15kg of urea, 10kg of ternary compound fertilizer, magnesium sulfate, and zinc sulfate per mu each time.

3. When the heart of the plant is red and the inflorescence is differentiated and developed, apply pre-flowering fertilizer, and apply 800kg of rotted chicken manure, 15kg of urea, 15kg of potassium chloride, magnesium sulfate and zinc sulfate per mu.

4. After the fruit is harvested, 500kg of fire soil, 700kg of rotting chicken manure, 15kg of urea, and 10kg of ternary compound fertilizer are applied to each mu.

5. Before the arrival of winter, apply potassium fertilizer to enhance the cold resistance of the plant.

6. Remove crown buds, dig up when the buds grow to 3-5cm, or remove when the buds grow to 145-20cm. Except for the descendant buds, each plant retains 2 descendant buds close to the base of the fruit stalk, and the rest are all removed.

7. If you want to harvest before December of the same year, you should promote flowering from April to early July. If the flowers are harvested in September, they can be harvested in May-June of the following year. Flowering method: Use 30-50ml of ethephon solution per plant.

8. At the end of flowering, use naphthalene acetic acid to spray, and continue to spray once every 15-20 days or so to promote fruit development.

Hello, dear is happy to answer for you. 1. Substrate selection Pineapples generally like to grow in peat* and perlite substrates that are light, loose and have good water retention, and to keep the substrate acidic or slightly acidic, the substrate should be disinfected before planting. 2. Seedlings are divided into ramel seedlings and tissue culture seedlings, which must be disinfected before planting, and generally soaked in carbendazim solution for half a minute.

3. Light conditions: Pineapples like a cool environment and cannot be exposed to sunlight. 4. Fertilization management of pineapple mainly relies on leaf cups to absorb nutrients, and liquid fertilizer should be used. Because pineapples are sensitive to some fertilizers, copper and chlorine can cause the plants to turn black or even die; Zinc can dry out leaf tips; Boron causes the leaves to curl or fall off; Too much phosphorus will also cause the symptoms of pineapple poisoning, it is recommended to apply more magnesium and potassium fertilizers, which is very helpful for the leaves to stretch and brighten the color.

5, promote the flowering of pineapple under natural conditions, it takes a certain amount of time to flower, in the cultivation, in order to make the pineapple bloom consistently, the general use of artificial flowering, the acetylene gas through the water for 30 minutes to become acetylene saturated aqueous solution, and then each plant watered 100-200 ml, every 3 days 1 time, a total of 3 times, can achieve the effect of flowering, generally in the flowering period 2 months ago, can not be fertilized when flowering, and control the number of watering, keep the plant properly dry, the end of flowering, you can apply potassium fertilizer. 6. Pest control pineapples generally have Spodoptera litura, in addition, the water quality is too poor, it is easy to lead to heart rot, the base of the leaf banquet shed is black, the heart leaf rot is brown, easy to fall off, generally use the concentration of carbendazim solution for watering, once a week, usually strengthen ventilation, regular disinfection. To sum up, the introduction of pineapple high-yield cultivation management methods is here, dear, I hope mine can help you, if you are satisfied with my service, please give a thumbs up, I wish you all the best!

Ornamental pineapple is a perennial evergreen herb native to the tropical rainforests of the Americas. Its common characteristics are: the roots are extremely underdeveloped, the water and nutrient absorption mainly depend on the leaves, and they prefer warm and humid climates.

The base leaves of pineapple are closely arranged in a lotus-like leaf tube, and some of the centers are cup-shaped to store water without leakage, so they should be irrigated frequently during cultivation and management to keep the center and leaves moist. In order to make it grow robustly, a small amount of foliar fertilizer needs to be applied to the leaf tube every 1-2 weeks, such as spraying Shibao, and the specific amount is determined according to the instructions for use on the foliar fertilizer and the growth of the flowers. Pineapples only bloom once in their lives, and after flowering, one to several buds will grow at the base of the old plant, so it is not advisable to divide the plants too early.

Otherwise, it is not easy to survive, the method of dividing the plant is: first cut off the flower stem from the base, and then leave 5-8 cm of the old plant leaves, and the rest are all removed, and the base of the leaves left is just formed a cylindrical water storage, and do not touch the small buds when cutting. When the bud is about 10 cm high, then use a sharp knife to gently cut from the bud and the mother plant connection, plant the small bud into the potting soil prepared with humus, and after careful maintenance for a year, it can bloom gorgeous flowers.

Ornamental pineapples not only have beautiful flowers and leaves, but also have fewer pests and diseases. However, due to the long-term storage of water in the leaf tube, the roots and leaves are easy to rot, so it is necessary to pay attention to the use of clean water when adding water to the leaf tube, and then use 500 times of chlorothalonil disinfectant to clean the roots and leaves for a long time to prevent rotting.

Yingge pineapple is a tropical plant, and what is the way it is cultivated is beautiful when the flowers bloom.

To plant pineapples, you need to choose a location that is convenient for transportation to build a garden and select suitable seedlings for cultivation. April to May of each year is the most suitable for planting, and the survival rate is the highest. After planting, potassium chloride and urea can be used for top dressing, and organic fertilizer should be used to increase the number of florets during the fruiting period.

Weeding work should be carried out in spring and autumn, and the harvest period should be inspected frequently, and harvested in batches and in a timely manner.

Pineapple likes acidity, it requires the pH value of water to be between to, and does not like salt, especially calcium salt and sodium salt. If the pH value is higher than 7, the plant will be malabsorbed and malnourished, and high calcium and sodium will make it.

The leaves lose their luster, hinder photosynthesis, and are prone to heart rot and roots.

Rot. Hard water contains too much calcium and magnesium salt, so it should not be used; Tap water also often contains a lot of sodium and chlorine, so it should not be used. Groundwater will vary depending on the region, and should be used after water quality analysis.

The principle of selecting the medium for cultivation media should be: pH value between, good water retention and drainage, stable physical and chemical properties, slightly coarse texture, strong firmness, cheap and easy to obtain.

According to the above principles, peat soil is better to use in greenhouses, but not in open shades. Particle size 1 cm left.

The coconut shell fragments on the right are also a more suitable medium. Fertilizing ornamental pineapples is more suitable for using liquid fertilizer, and slow-acting fertilizer can also be used for liquid fertilizer formulation, which should meet the following requirements: pH value.

0；The ratio of various nutrient elements n—p2o5 k2o mgo should be . If flowering is promoted, nitrogen fertilizer should be removed 2 months before flowering. Liquid fertilizer is sprayed every 3 days, 30 ml per plant each time. The fertilizer can choose Bika water-soluble fertilizer.
