Where do pineapples grow?
Among many tropical fruits, pineapples often arouse people's curiosity about how they grow due to their unique appearance. This kind of fruit with its own crown does not hang on branches like a coconut, nor does it crawl on the ground like a watermelon. Its growth method contains the special wisdom of the plant kingdom. When you look closely at the pineapple plant, you will find that sword-shaped leaves are surrounded at the top of the short and thick stems. These leathery leaves are arranged in a spiral structure to form a natural water storage system. After 18-24 months of vegetative growth, purple-red inflorescences will emerge from the top of the stem. After 150-210 days of development, the familiar pineapple fruit is born from this receptacle made up of more than a hundred small flowers. Scientific maintenance method for pineapples precise temperature control As a typical tropical plant, pineapples grow most vigorously at 25-32℃. It is worth noting that controlling the temperature difference between day and night to within 8 ° C can promote sugar accumulation, which is also an important reason why Hainan pineapples are particularly sweet. When the temperature is lower than 15℃, it is recommended to build a simple greenhouse for protection. Intelligent management of light 6-8 hours of direct light per day allows the leaves to fully photosynthesis, but special attention should be paid during the fruit expansion period: when the peel begins to turn yellow, putting a fruit bag with a light transmittance of 50% can prevent sunburn spots. Produce and ensure normal conversion of sugar. The optimal configuration of soil for ideal planting substrates needs to meet three conditions: an acidic environment with a pH value of 4.5-5.5, a gravel content of more than 30%, and a humus content of more than 5%. Regular addition of pine needle soil or sulfur powder can effectively maintain soil acidity, which is a key point that many growers easily overlook. The scientific supply of water adopts the "wet-dry" alternating irrigation method: the soil moisture is maintained at 60% during the new leaf growth period, reduced to 40% during the flower bud differentiation period, and completely cut off water 30 days before fruit ripeness. Adjust the water supply by observing the condition of the leaves-the curling of the leaves indicates a lack of water, and the redness of the leaf base indicates water accumulation.
After mastering these core points, even if we use waste pineapples to top the crown for hydroponic cultivation on the balcony, we can harvest mini pineapples in about 3 years. This planting process, which has both ornamental and edible values, is allowing more and more urban people to experience the growth charm of tropical crops.
