How can you keep a green pineapple in winter? It is native to the tropical rain forest area and likes warm and humid environment. The best growing temperature is 20 ℃ to 30 ℃. In winter, the weather is cold and the climate is dry, which is not suitable for the growth of green pineapple. Therefore, it needs skills to have a safe winter, so where is the secret of keeping green pineapple in winter? If you have green pineapple at home, you can have a look.
1. Pay attention to the light in winter. But in winter, in order to supplement the deficiency of temperature and photosynthesis, we should increase the illumination. The method is to put the green pineapple in the best indoor lighting place, or move to the sealed balcony at noon to bask in the sun, and at the same time, when the temperature is low, open the window as little as possible, because in a very short time, the leaves may be frostbitten.
2. Pay attention to the temperature in winter. In the north, when the room temperature is above 10 ℃, the green pineapple can survive the winter safely. When the room temperature is above 20 ℃, the green pineapple can grow normally. It is not a big problem for families to reach this temperature. It is necessary to avoid excessive temperature difference and pay attention to keep the leaves away from the heating equipment.
3. Pay attention to humidity in winter. Under the condition of ensuring normal temperature, increasing humidity is very beneficial to plant growth. To increase humidity, we can use the following methods: make plants close to humidifier, the humidifier's opening time is more than 5 hours a day, spray the spray to the leaves, stems and roots of plants with spray scales, spray water several times a day, maintain proper moisture in the flowerpot tray, and increase the local humidity of plants through evaporation. Wipe the leaves lightly with cold wet towel or toilet paper or apply the leaves lightly in a short time (1-2 hours a day); cover the plants with transparent plastic film to create the effect of small greenhouse, supplement the water of plants by evaporating the moisture in the soil, no more than 2 hours a day, too long time will affect the ventilation and Photosynthesis of plants.
4. Pay attention to watering in winter. The amount of water in winter should be strictly controlled according to the room temperature. After heating, do not water too much, water less to the basin, should be infiltrated by brown silk. In addition, water should also be sprayed on the air rooting part of the brown column to reduce the root water absorption caused by the rapid evaporation. The water poured in winter is better than the water after a day's drying, and it is easy to damage the root if it is too cold.
5. Pay attention to fertilization in winter. In winter, plants grow slowly and should be fertilized less. After winter, foliar spraying was the main way of fertilization. Foliar fertilizer should be special fertilizer. Ordinary inorganic fertilizer is not easy to be absorbed. You can use foliar fertilizer such as Peking University huhuashen series and Japan huayifan.
