How can Cycas bloom?
Cycas usually bloom in summer and are dioecious. If it wants to bear mature fruit, it needs successful pollination. If you want Cycas to blossom as soon as possible, you need to provide a suitable growth environment first, and then carry out scientific maintenance and management. Only when a plant reaches a certain age and meets the conditions of flowering can it see its flowering scene.
First, the quality of basin soil is high. Because the roots of Cycas are mostly fleshy fibrous roots, it is necessary to ensure air permeability and water permeability when mixing soil, to ensure that its roots can breathe smoothly, and to avoid root rot caused by excessive watering. But also acidic plants, so the soil we prepare should be slightly acidic. Generally speaking, we can make a mixed matrix with humus soil, pastoral soil and coarse sand in the ratio of 3: 2: 1. Of course, 0.5% ferrous sulfate can also be added to adjust soil acidity. In this way, we have prepared fertile, loose, breathable and permeable slightly acidic sandy soil for it, which is very beneficial to its growth.
Second, sufficient light Cycas is a tropical sunny plant, and sufficient light is one of the prerequisites for its healthy growth. Because the more sunlight, the stronger photosynthesis, the more nutrients formed, and the better plant growth. However, when the light is too strong in summer, shading measures should be taken in time to provide only enough scattered light. In other seasons, it is necessary to get more sunshine to ensure sufficient illumination, so as to lay a good foundation for its future flowering and growth.
Third, the temperature is suitable. Because Cycas is a tropical tree species, it naturally prefers to grow in a higher temperature environment, and usually has a certain high temperature resistance. However, cycads are not cold-tolerant. In winter, measures must be taken to keep warm and keep out the cold in time to avoid freezing injury and affect the normal growth of plants. In general, it is necessary to provide 20? C-30？ C, and the lowest temperature in winter should not be lower than 6? C, this can ensure that plants can survive the winter safely.
Fourth, water the right amount of Cycas to fight drought and not waterlogging. It is necessary to avoid excessive watering and try to be "dry and wet, dry and thorough". At the same time, we also need to pay attention to maintaining proper air humidity, because if the air is too dry, especially in summer, the leaves of plants are easy to become smaller and wither. Generally, it is more appropriate to water every 3-6 days in spring and autumn. In Xia Dong, increase or decrease is considered according to the specific situation, but in summer, the frequency of watering every morning and evening can generally be maintained; Water is usually poured once every 7- 10 in winter.
5. The nutrient-rich root system of Cycas is very developed, but the fleshy root is also very fragile. Although it likes fertilizer, it needs to control its concentration to avoid burning its roots due to fertilizer damage. In addition to applying sufficient base fertilizer, rare organic liquid fertilizer or compound fertilizer can be applied once a month in the growing season to supplement nitrogen, phosphorus and potassium nutrients. Generally, Xia Dong does not need deliberate fertilization in season, but only needs to manage the temperature, humidity and ventilation.
6. Pot-turning and soil-changing Cycas generally need a pot-turning and soil-changing treatment on a regular basis after two years of potted plants, combined with root pruning. Moreover, it is best to turn over the pots and change the soil in spring, which is more conducive to the survival of plants in the pots. When pruning the root system, in addition to pruning the old, weak, sick and disabled roots, we should try our best to keep the strong roots. At the same time, it is necessary to provide a high-quality flowerpot for plants, regardless of material or size, which should be suitable for the growth of cycads; In the case of basin soil, slightly acidic sandy soil with rich air permeability and strong water permeability is still used.
Seven, shaping and pruning The shaping and pruning of Cycas is not only very important for modeling, but also conducive to promoting plant growth and accelerating its flowering. Pruning is usually done once every two years when the pots are turned over and the soil is changed, mainly to cut off the old, weak, sick, residual branches and dead leaves produced by the plants. This can not only save a lot of nutrients, but also make the plant look more beautiful, grow more vigorously and bloom more easily in the future.
Eight, pest control The common pests and diseases of Cycas are mainly leaf spot and scale insects. Once plants are found to be infected with pests and diseases, they should be sprayed in time. At the same time, it is necessary to improve the conservation environment in time, because the diseases and pests of Cycas are often caused by the deterioration of the conservation environment. In the case of good pest control management, we can better ensure that plants can grow normally and grow more vigorously, and provide the necessary guarantee for future flowering.
