Potted pineapple-how to raise it in the south and north?

Pineapple plants native to the tropical rain forest of South America, are herbaceous epiphytic tropical plants, heat and early tolerance, more cold-tolerant. Although pineapple plants are huge and can be classified into more than 50 genera according to their morphological characteristics, they are favored by consumers as a commercial variety. Below, the editor of Tuliu.com will introduce to you how to grow potted pineapples.

1. Lighting

Most of the cultivated pineapples need less than 2000x light intensity, and some need 2500Lx, such as Magnolia and so on. However, in the process of actual production and cultivation, in order to achieve ideal leaf color and plant shape, the light intensity is usually controlled at 1200-20000Lx, especially in the suburbs or mountainous areas of Guangdong with strong ultraviolet rays, the active double-layer shading net should be used at noon and in the middle of summer.

2. Temperature

The most suitable growth temperature of pineapple is 20 ~ 30C, and the temperature difference between day and night should be kept above 6C. However, most varieties of the pineapple family can survive the winter safely above 5C, and some varieties can withstand short-term 1cm 2C, while some varieties can continue to grow at 35% C in summer. However, in the muggy and hot summer, we should pay attention to the ventilation of the culture place, otherwise it will affect the growth.

3. Humidity

The best growth humidity of pineapple is between 55% and 75%. If the humidity is less than 40%, it is easy to cause plant leaf tip drying and leaf curl. At this time, the spray in the war culture place should be strengthened to increase the humidity. In summer, high temperature and humidity should strengthen ventilation, while low temperature in winter should reduce water spraying.

4. Cultivation medium

The suitable cultivation medium should be selected according to each growth stage of pineapple, usually the finer medium is selected in the small seedling stage, and the thicker medium is selected in the large seedling colonization. In a word, the medium with stable structure, good water retention and drainage performance should be selected, and the pH value and EC value of the medium should be fully understood. In the actual production process, the performance of imported peat soil medium is ideal.

5. Water quality

Pineapple plants also have strict requirements for water quality. It is recommended to use Rain Water (as long as the area is not a seriously polluted area) and deionized water, because the pH value and EC value of Rain Water and deionized water can basically meet the needs of pineapple. Some enterprises use tap water, but tap water contains fixed salt and chlorine, and the EC value is unstable, especially in winter, which has a great impact on the growth of pineapple, so it should be treated carefully or used as appropriate after treatment, monitoring and adjustment.

6. Fertilization

The fertilizer supply of pineapple is realized by formula liquid fertilizer. At present, most production enterprises use special pineapple fertilizer, and most of them are imported fertilizer, which has a good effect on one or some varieties. In actual production, more than three kinds of formula fertilizers are recommended, but granular fertilizers or slow-release fertilizers are generally not recommended, because they are difficult to control the supply of nutrients. It should be noted that the fertilizer provided should not contain boron, while excessive phosphorus will cause the top of the plant to burn, and excessive zinc and copper will cause plant death; but all pineapple varieties need magnesium fertilizer, which will cause the old leaves to turn yellow when lacking, and the recommended dosage is 3% and 8%.

All right, this is how to breed potted pineapple plants brought by the editor of Tuliu.com. I hope you like it. So I'll see you next time.
