What are the main points of the culture method of pineapple?

Pineapple is one of the most popular varieties of indoor ornamental plants. Its leaves are colorful and its flowers are colorful and attractive. Therefore, many families use it to decorate their homes. So, what is the culture method of pineapple? What are the main points?

Pineapple, a genus of the pineapple family, native to jungles from Mexico to southern Brazil and northern Argentina, with about 50 species, mostly geophytic. The leaves are sickle-shaped, the upper part is inclined downward, and there are 5-8 rosette-shaped leaves arranged in a tubular shape. At present, the flower has become a strong ornamental flower and foliage plant, especially can be cultivated indoors, as a family horticulture with high taste.

1. Lighting

Pineapple habits like semi-overcast, should prevent the hot sun exposure, put half-shaded place or bright window, indoor. The original state of the pineapple is parasitic under a tree in the tropical rain forest, so it does not have a great demand for sunlight. When the sun is exposed to too much time, it will produce part of the leaves yellowing, and then the flower tip is a little dry. If cultivated outdoors, it should be properly shaded in spring, summer and autumn, especially 70% shading in summer.

2. Temperature

The optimum growth temperature of cultivated pineapple is from 20 ℃ to 30 ℃, the highest temperature should not exceed 35 ℃, the lowest temperature is 14 ℃, and freezing injury may occur at any time when the temperature is lower than 10 ℃. It's best not to put it under the heater in winter.

3. Moisture

Pot soil watering to basin soil surface slightly dry, that is, the soil surface 1 "2 meters dry, and then water the second time, too wet easy to soak the root. All plants of the pineapple family have a leaf tube at the root of the leaf, and the leaf tube has a sink. It is necessary to ensure that there is often water in the tank, which cannot be cut off. After a period of time, for example, about ten days, the water in the leaf tube should be replaced to avoid smelly water. Usually, you can also spray some foggy water on the surface, leaves, and flowers. The optimum air relative humidity is 70% to 80%, not less than 50%.

4. Using soil

Potted plants should choose a mixed substrate with good drainage, such as peat, perlite and sand, the proportion of which is: 1 cubic meter of peat: 4 to 5 kilograms of perlite: 0.15 cubic meters of sand. The PH value remains between 5.5 and 6.5. If you can put a small amount of rotten chicken manure, cake powder or bone meal and other base fertilizer in the bottom of the basin, it will grow better.

5. Fertilization

During the growing season from April to September every year, liquid fertilizer should be applied every two weeks, fermented organic fertilizer can be applied, 0.1% urea and 0.2% potassium dihydrogen phosphate solution can be sprayed on both sides of the leaves, and some extremely thin liquid fertilizer can be injected into the blade tube. Absorbed by its basal scales, the ratio of nitrogen, phosphorus and potassium is 10: 15: 20.

6. Reproduction

It is usually propagated in separate plants. at present, tissue culture is often used for mass propagation, and seeds are used for breeding. The tiller buds of the adult mother plant can be divided and planted in spring, and the young leaves are mostly used as explants in tissue culture, which are induced by callus to differentiate buds, then rooting and seedling formation, and it takes about 4 months from inoculation to seedling transplantation. flowering 2-3 years after planting.

It seems that the cultivation of pineapple is not easy and needs careful maintenance. Perhaps it is for this reason that this kind of flower can show people with its bright and dazzling appearance, and perhaps for this reason, its ornamental value is higher.
