The growth cycle of canna leaves The reasons why canna leaves change The practical value of canna leaves change In the vibrant plant world, canna has become a favorite in many gardens and flower beds with its unique posture and bright flowers. In addition to the eye-catching flowers, the leaves of canna are also full of changes. Their changes not only reflect the growth laws of plants, but also contain the secrets of life in nature. This article will take you into the leaf world of canna and find out. Growth cycle of canna leaves The leaf growth cycle of canna canna can be divided into three stages: germination stage, growth stage and maturity stage.
1. Germination period During the germination period of Canna japonica, the leaves show a bright green color, the leaves are thin, and the texture is soft. The leaves are mainly responsible for photosynthesis and provide nutrients to the plant. According to relevant data statistics, the germination period of Canna japonica japonica takes about 10-15 days.
2. After the growth period enters the growth period, the leaves of canna begin to grow rapidly, gradually becoming thicker, and the color changes from tender green to dark green. The leaves at this stage are the main organ for photosynthesis of canna, providing sufficient nutrients for the plant. According to industry reports, the leaves of canna can reach 30-50 cm long during the growth period.
3. Maturity period When the leaves of Canna indica enter maturity, the color of the leaves becomes brighter and the texture becomes more tough. The leaves have completed most of the photosynthesis tasks and begin to gradually age. According to statistics, the leaves of Canna japonica will take about 60 to mature. -90 days. The main reasons for the changes in canna leaves are as follows: 1. Light intensity Light intensity is a key factor affecting the growth of canna leaves. In a sunny environment, canna leaves grow faster and the color is brighter. In the shade, the leaves grow slower and darker.
2. Water supply Water is an important condition for the growth of canna leaves. When there is sufficient water, the leaves grow vigorously and are bright in color. On the contrary, the leaves grow slowly and are dull in color.
3. Soil nutrients Soil nutrients also have a great impact on the growth of canna leaves. Soil rich in organic matter is conducive to the growth of canna and makes the leaves brighter.
4. Plant varieties Different varieties of Canna indica have different leaf growth rates and color changes. Varieties with faster growth rates and bright colors have more obvious leaf changes. Practical value of Canna leaf changes Understanding the process of Canna leaf changes is of great significance to maintaining Canna. The following are some practical suggestions: 1. Reasonable watering According to the growth characteristics of Canna leaf, reasonable watering is to ensure its healthy growth. The key is to ensure that the soil is moist during the germination and growth periods; appropriately reduce the number of watering times during the maturity period.
2. Reasonable fertilization According to the growth needs of Canna indica leaves, reasonable fertilization can promote their growth. During the germination and growth periods, appropriate amounts of nitrogen fertilizer can be applied; during the maturity period, appropriate amounts of phosphorus and potassium fertilizer can be applied.
3. Pruning the leaves of canna at a timely time can promote plant growth and improve ornamental value. During the growth process, sick and weak leaves should be removed in time to keep the plant ventilated and transparent.
The change of Canna's leaves is a charming growth process. Understanding its changes will help us better maintain Canna's leaves and let this beautiful plant bloom in our lives.
