Bromeliad cultivation methods and precautions How to raise ornamental pineapple flowers

Cultivation methods and precautions for ornamental bromeliads, taking purple pineapples as an example:

1. Potting soil selection: When choosing a pot, you need to choose a plastic pot that is not transparent, and the size of the pot should be determined according to the size of the plant, which is generally slightly larger, which can meet the further growth of purple pineapple. The soil should be acidic, and the water retention and drainage should be better.

Peat soil is generally used, and some perlite, humus, vermiculite, etc., are mixed to make the soil breathable.

2. Light and temperature: Purple pineapples need sufficient light, and when the light is strong, maintain humidity and strengthen ventilation will make purple pineapples grow faster and bloom more gorgeously. Insufficient light will cause purple pineapple plants to grow and reduce ornamentality.

Therefore, purple pineapples need to maintain sufficient sunlight every day, but it should be noted that the light in summer should not be too strong and need to be properly shaded.

Purple pineapples grow at a suitable temperature of between 20 and 30, which can be reduced by shading and ventilation in the summer when the temperature is hot, and in the winter when the temperature drops, it needs to be kept warm.

3. Watering and fertilization: Purple pineapple needs certain nutrients and water to grow, summer and autumn are the peak growth seasons, need more water, you can water once every 1 to 3 days, watering to the center of the plant. Winter is the dormant period of purple pineapples, watering should be controlled, watering once a week, the potting soil is not dry or watered, and it cannot be too wet.

Fertilization should ensure the various nutrients needed for the growth of purple pineapples, and fertilize fertilizers with elements such as nitrogen, phosphorus and potassium according to a certain ratio.

Propagation method: The propagation of purple pineapple is mainly to plant basal buds, or sowing propagation.

Pests and diseases: Purple pineapples are susceptible to red spiders and clear points in the process of growth, and need to be sprayed with fruit butter.

1. Temperature.

Bromeliads, mainly in tropical rainforest areas, prefer to grow in high temperature and humid environments. If you need to breed indoors, you must grasp the factors such as sunlight, moisture, and air. Generally speaking, it is best to control the room temperature at 15-20, which is conducive to the growth of bromeliads.

From the point of view of temperature, bromeliads are suitable for indoor cultivation. In terms of soil, it is moist and suitable for the growth of bromeliads in the high season. Therefore, during the flowering stage, it is necessary to spray water all around it every day to increase the moisture in the air and soil.

2. Illumination. Bromeliads like semi-shade, so they should be avoided from the scorching sun, and it is recommended to put them in a window with light. Pineapple is parasitic in tropical rainforests, so it does not need much sunlight, and when there is too much light, some leaves will yellow, and then the tips of the flowers will dry out a little. If it is cultivated outdoors, you should pay attention to shade in spring, summer and autumn, especially in summer, direct sunlight will cause burns and scorched leaves, resulting in slower growth of leaves.

3. Fertilization. Bromeliads are parasitic plants, so the root system is underdeveloped, and there is no taproot, so it is not recommended to add too much fertilizer to the pot, which is the main reason why the leaves are yellow and the roots are rotten. For this reason, it is recommended to plant it in small pots, so that its roots are exposed to the air, and the soil will be better if it is mixed with a little pastoral soil, or peat in half.

4. Reproduction. Nowadays, the most common cultivation method is to propagate in large numbers and divide the plants in the spring. The culture mostly uses young leaves as explants, which are induced by callus to differentiate and cluster buds, and then induce rooting into seedlings. Generally speaking, it takes about 4 months from inoculation to transplantation, and after planting, it can bloom in 2-3 years.

5. Precautions for bromeliad breeding.

In the process of cultivating bromeliads, we must prune them in time, especially the dead branches and leaves, so as to maintain its beauty. In addition, after the bromeliad enters the flowering period, it is necessary to pay attention to the adjustment of water and fertilizer, and minimize the number of fertilization, keep the water sufficient, and effectively prolong its flowering period.

1. Breeding methods.

1) Wenkai Qi degree: its most suitable temperature is about 30, the lowest temperature should be between 12-20, not as low as 12, otherwise it will freeze the plant.

2) Watering: It is a water-loving plant, so it should be watered more and ensure that its soil moisture is high enough. When watering, you must be careful not to pour water on the leaf clusters, otherwise the leaves will rot and star.

3) Fertilization: It has high requirements for fertilizer and water, and must be fertilized frequently, but each time it is less fertilized, it must not be fertilized indiscriminately, and nitrogen, phosphorus, and potassium are too much fertilizer.

4) Potting soil: It can be mixed with sawdust, humus soil, sand river soil, etc., and the potting soil must be aerated to facilitate the growth of pineapples.

2. Precautions.

1) It is easy to get sick during the breeding period, so it is necessary to spray the drug every 15 days or so to prevent it.

2) It can absorb heat dissipation light and cannot be exposed to strong sunlight.
