Three Taboos in Chrysanthemum Cultivation
Plant knowledge section, sharing with you the related knowledge of chrysanthemum, a plant of the Compositae family. There are three taboos in chrysanthemum cultivation. The following editor will explain in detail for you.
The ecological characteristics of chrysanthemum determine that it is not suitable for continuous cropping. Continuous cropping of chrysanthemum leads to a decline in soil fertility, and the soil structure and nutrients cannot adapt to or meet the growth and development of chrysanthemum. Chrysanthemums that have been continuously cropped often show plants that are thin and old, leaves that are small and yellow, flowers that are small and not bright in color, and serious diseases and pests. Therefore, it is best not to plant chrysanthemums on the land where chrysanthemums have been planted for two to three years, and the soil used for potted chrysanthemums must not be used to plant chrysanthemums next year. In one sentence, do not plant chrysanthemums continuously.
Firstly, avoid using uncomposted organic fertilizer
Organic fertilizer refers to human and animal waste, cake fertilizer, and barnyard manure, etc. Organic fertilizer is commonly used and the main fertilizer for cultivating chrysanthemums. The nutrients in organic fertilizer are in a slow-release state and must be decomposed and matured to be converted into an effective state for plant absorption. Uncomposted organic fertilizer also contains various pathogens and parasite eggs; it can also produce fermentation heat and organic acids. After use, chrysanthemums will be severely affected by diseases and pests; there will be phenomena of burning the leaves and damaging the roots. Therefore, when using organic fertilizer, it must be fully composted to fully utilize its fertilizer effect and avoid negative effects.
Secondly, avoid splashing mud on the leaves of chrysanthemum
The quality of chrysanthemum leaves is an important condition for evaluating the ornamental value of chrysanthemum. Therefore, extra care should be taken to protect the leaves and avoid damage from human and natural factors as much as possible.
Prevent rain from splashing mud on the leaves, and if the leaves are stained, they should be washed with clean water promptly after the rain.
When applying fertilizer, prevent the fertilizer water from contaminating the leaves to avoid the shedding of the lower leaves.
Watering should be careful to prevent mud from splashing on the leaves to avoid disease and leaf shedding.
Thirdly, avoid waterlogging and浇 "half-watering"
As the saying goes, "dry orchids, wet chrysanthemums," "wet chrysanthemums" is a comparison with orchids, not the more water the better. Chrysanthemums prefer moist conditions but dislike waterlogging. If the soil remains too moist for a long time, it will severely affect the respiration of the chrysanthemum roots, leading to oxygen deficiency and root rot. Therefore, it is necessary to remove accumulated water in time during rainy days and prevent waterlogging by倾斜 the pot.
When watering chrysanthemums, it is not appropriate to let the soil be too dry or too wet, nor half-dry and half-wet. Chrysanthemums need sufficient water and must not be watered with "half-watering," which means that only the surface soil is moist, and the roots in the deep soil are still in a dry state. If this continues, the lighter cases will result in the aging and leaf shedding of the plant, while the severe cases will cause the whole plant to wither and die. Therefore, when watering chrysanthemums, the principle of "thoroughly wet and sufficient" should be followed.
That is a detailed introduction to the three taboos in chrysanthemum cultivation. Do you understand now?
