What does a chrysanthemum look like?
In the golden autumn season, chrysanthemums light up the color of the season with their various flower shapes. As a famous traditional flower in China, chrysanthemum not only carries cultural connotations, but also attracts plant lovers with its unique biological characteristics. Let us discover the mystery of chrysanthemums through 6 real-shot illustrations and master the secrets of scientific maintenance. Analysis of morphological characteristics of chrysanthemum, stem structure characteristics, the stem of chrysanthemum shows upright growth characteristics, with a height range of 60-150 cm, and the young stem shows a two-color gradual change of tender green and transparent brown. Mature plants have obvious differentiation between aboveground stems and underground stems. After the aboveground stems wither in winter, the underground stems will germinate new buds in the spring of the following year, showing tenacious vitality. Leaf growth form Alternate leaves are ovate or lance-like, with a leaf length of 5-15 cm matched with thick serrated edges, and the back of the leaves is densely covered with white pilose to form a natural protective layer. This special structure not only reduces water evaporation, but also protects against the invasion of some pests. The inflorescences constitute the mystery. The head inflorescences are composed of hundreds of small flowers arranged in precision. The outer involucral bracts are in a green protective form, and the inner ligulate flowers are specialized to form the ornamental body. The colors cover white, yellow, red, purple and other color spectra. The petal shapes have evolved into three categories: single petals, flat petals, and spoon petals. They form a visual feast when they bloom from September to November every year. Guide to Scientific Conservation of Chrysanthemum Substrate ratio plan What does Chrysanthemum look like?
A slightly acidic sandy loam with a pH of 5.5 -6.5 is preferred, and the ratio of humus: perlite: vermiculite =5:3:2 is used to ensure that the substrate has both fertilizer retention and drainage properties. High temperature disinfection is needed before planting to prevent soil-borne diseases. As a typical short-day plant, photoperiod control needs to ensure more than 14 hours of light per day to promote nutrient accumulation during the growth period. The flower bud differentiation period is adjusted to 8-10 hours of light, which can accurately control the flowering period through shading treatment. The rhythm of water and fertilizer management adopts the watering principle of "seeing dry, seeing wet", which is watered once in the morning and evening in summer, and is coordinated with leaf spray to cool down. A balanced nitrogen, phosphorus and potassium fertilizer (NPK 20-20-20) is applied every 10 days during the growth period, and a high phosphorus fertilizer (NPK 10-30-20) is used during the bud appearing period to promote flower bud development.
