[cultivation of pineapple] how to raise pineapple

Pineapple is a highly ornamental flower and leaf plant, especially can be cultivated indoors, as a family horticultural ornamental is very high taste, let's enjoy and understand the pineapple flower:

I. cultivation of pineapple flowers

Pineapple is an epiphyte, native to the tropical rain forests of Central America. From the original environment of pineapple, most pineapples prefer semi-shaded environment and avoid direct sunlight. Generally speaking, the suitable photometric environment of pineapple is about 18000lux, and the relative humidity needs to be maintained between 68ml and 75%. In terms of temperature, it is required to be around 22mi 28C in the daytime, and it is best to maintain it at about 20mi 21C at night. Pineapple flowers are very sensitive to relative humidity (RH). Under strong light or drying, when the humidity is less than 50%, the leaves will curl inward or cannot be extended. Therefore, in an environment with high light intensity, we should properly match the humidity above 75%. Although pineapple likes humid environment, it is easy to cause insufficient ventilation during the period of high temperature and humidity in summer, which hinders growth and is easy to attract diseases and insect pests, so it is necessary to maintain ventilation. Under strong light, the air humidity is less than 65%, or the air is well ventilated when dry, which can also cause the leaf tip to wither. It should be noted that if the spike is exposed to high temperature (30 degrees), the color of the spike will fade and the florescence will be shortened.

Second, the propagation method of pineapple.

Sowing and reproduction

It is appropriate to sow seeds under aseptic conditions. After picking the ripe but uncracked fruit, rinse the 15min with clean water, scrub the pericarp with 75% alcohol, sterilize the 12min with 10% hydrogen peroxide, then rinse the fruit with sterile water for 3 times, cut the fruit, take out the seeds, and sow the seeds in the solid medium, the medium is 1pm 2ms 2% sucrose + 1% activated carbon. Using this method to sow seeds, taro can be sprouted in about a month, and the germination rate can reach more than 80%. When the true leaves of the plant grow to about 5, they can be transplanted in a bottle.

Ramet propagation

After appreciating the flowers of the pineapple, multiple sucking buds will be produced in the axils of the basal leaves. The suitable period for ramets is usually from April to June. When the sucking bud grows to about 10cm and has 3-5 leaves, the whole plant is removed from the basin first, some basin soil is removed, one hand grasps the mother plant, the thumb and index finger of the other hand tightly clamps the base of the sucking bud, and the suction bud can be broken off by oblique force. The wound is slightly dried after disinfection with fungicide and inserted in perlite and coarse sand. Keep the matrix and air moist and shade properly. After 1-2 months, the new roots can be transferred to normal management.

Third, the culture method of pineapple.

Cultivate good pineapple, mainly to understand its growth habits, pineapple is native to the American tropics, considering the tropical high temperature and humid environment, so, family culture should also try to create its primitive growth environment, such as sunshine, water, air, etc., pineapple flowers can grow well between 15 colors and 20 degrees, and water can be sprayed to the leaves every day to increase air humidity.

The root system of pineapple is not well developed, and cutting stem cuttings or bud transplanting are often used, which can greatly improve the survival rate. If pineapple flowers are to bloom vigorously, attention should be paid to the non-accumulation of water in the pot during flowering, and proper measures to avoid light can effectively prolong the flowering period.

In the pineapple growing season, it is necessary to appropriately increase the amount of water, and if necessary, you can also pour some water into the leaf tube, but change the water in time to avoid smelly water. From May to September, it is the growing period of pineapple flowers. At this time, you can apply one flash of nitrogen fertilizer a week and apply phosphorus and potassium fertilizer once a week before flowering to make the flowers big and colorful.

The most important thing to plant Phoenix pear flower is to maintain it according to its growth law, which can prolong its flowering period. The above are the pineapple culture methods and matters needing attention. I hope it will be helpful to you who read the article.
