2. Temperature: The suitable growth temperature of Cycas brasiliensis is 20 ~ 28℃, the dormant temperature is 65438 03℃, and the overwintering temperature is 5℃. If the temperature is too low, chloasma will appear at the tip and edge of the leaves, and in severe cases, the shoots or the whole plant will be frozen. Therefore, it is necessary to move into a greenhouse for maintenance in the northern winter. If it is placed indoors, it should be placed in a sunny place, and the room temperature should be kept above 6℃ to 8℃. When the temperature is low at night, you can put on a plastic bag to keep warm. When the sun comes out during the day and the room temperature rises, it is necessary to take down the plastic bag in time to cool down and prevent suffocation.
3. Illumination: Brazilian iron has a wide range of adaptability to illumination, but the strong light note from May to1October causes the leaves to turn yellow or the tip to turn yellow, so it is necessary to pay attention to shading and give bright scattered light; Although it is also shade-tolerant, too shaded environment will make the leaf color dim, especially for variegated varieties, the markings on the leaves are easy to disappear, which reduces the ornamental value.
4. Humidity. Cycas brasiliensis doesn't need much water, but it needs high humidity. After the basin is lifted, water the foot root and place it in a bright room or a cool shed for maintenance. The basin soil should be kept moist, and the leaves should be sprayed with water frequently to improve the air humidity of the surrounding environment, but the basin soil should not accumulate water to avoid root rot caused by poor ventilation.
5. Watering: After the potted plants are put away, water their feet and put them in a bright room or shade shed for maintenance. The basin soil should be kept moist, and the leaves should be sprayed with water frequently to improve the air humidity of the surrounding environment, but the basin soil should not accumulate water to avoid root rot caused by poor ventilation. Cycas brasiliensis should be maintained in the growing season of spring, summer and autumn. Water 1 time every 2 ~ 3 days in sunny days, and water 1 ~ 2 times per day is appropriate for the leaves. After the end of autumn, it is advisable to control the amount of watering and keep the basin soil slightly wet. Water should be controlled in winter, and the basin soil should be kept half dry and half wet. If it is drenched too much, the roots and leaves will rot.
6. Fertilization: Cycas brasiliensis needs to consume some of its own nutrients during its growth. If fertilization is not timely, it will lead to insufficient stamina and gradual degradation. During the growth period, organic fertilizer should be buried at the base or edge first, and then liquid fertilizer or compound fertilizer should be applied12 times every 15 ~ 20 days to ensure the flourishing growth of branches and leaves. Thin fertilizer should be applied instead of thick fertilizer, and the fertilization period is from May to 10 every year. Stop fertilizing in winter and move indoors for the winter. For striped varieties, attention should be paid to reducing the proportion of nitrogen fertilizer when fertilizing, so as not to cause the white leaves to grow, leading to the darkening or even disappearance of stripes.
Cycas brasiliensis plants are tall and straight, elegant and full of tropical atmosphere. Several stems of different heights were planted into large potted flowers to decorate the venue. The living room and lobby are dignified and elegant, full of natural interest. Small potted plants or hydroponic plants decorate the windowsill, study and bedroom of the living room, which is more beautiful and generous.
Cycas brasiliensis has a temperature of 16 ~ 18℃ and a relative humidity of 80% ~ 90%, and can endure 15 days in the dark. However, plants with temperature lower than 8℃ are vulnerable to freezing injury during storage and transportation, and low air humidity will cause serious necrosis of leaf margin tissue.
