Abstract: Short-day Plants: Types, Growth Characteristics, and Management Techniques
The growth and development of plants are greatly influenced by the photoperiod. Among them, short-day plants can only carry out growth processes such as flowering when the daylight duration is less than 12 hours. These plants are generally distributed in mid-to-high latitude regions outside the tropics. When grown in greenhouses or indoors, special attention must be paid to the control and management of sunlight. This article will introduce some common types of short-day plants, their growth characteristics, and management techniques.
Azalea
Azalea is a typical short-day plant that requires less than 12 hours of daylight to bloom, usually in late spring or early summer. When grown in a greenhouse or indoors, the light duration should be controlled, and attention should be paid to ventilation and moisture retention.
Chrysanthemum
Chrysanthemum is also a short-day plant that requires less than 12 hours of daylight during its growth period and can bloom in autumn. When grown in a greenhouse or indoors, the light duration should be controlled, and attention should be paid to drainage and fertilization.
Begonia
Begonia is a relatively easy-to-grow short-day plant that requires less than 12 hours of daylight during its growth period and can bloom in autumn. When grown in a greenhouse or indoors, the light duration should be controlled, and attention should be paid to proper pruning and increased humidity.
Jasmine
Jasmine is a common short-day plant that requires less than 12 hours of daylight during its growth period and can bloom in spring or autumn. When grown in a greenhouse or indoors, the light duration should be controlled, and attention should be paid to keeping the soil moist and fertilizing.
Clematis
Clematis is a relatively cold-hardy short-day plant that requires less than 12 hours of daylight during its growth period and can bloom in spring or autumn. When grown in a greenhouse or indoors, the light duration should be controlled, and attention should be paid to maintaining ventilation and increasing humidity.
Lily
Lily is a relatively shade-tolerant short-day plant that requires less than 12 hours of daylight during its growth period and can bloom in summer. When grown in a greenhouse or indoors, the light duration should be controlled, and attention should be paid to maintaining soil aeration and fertilizing.
Calamus
Calamus is a relatively warm-loving short-day plant that requires less than 12 hours of daylight during its growth period and can bloom in summer. When grown in a greenhouse or indoors, the light duration should be controlled, and attention should be paid to keeping it moist and applying moderate fertilizer.
Narcissus
Narcissus is a common short-day plant that requires less than 12 hours of daylight during its growth period and can bloom in winter. When grown in a greenhouse or indoors, the light duration should be controlled, and attention should be paid to maintaining ventilation and applying moderate fertilizer.
Light Control
When growing short-day plants in a greenhouse or indoors, the light duration and intensity should be controlled according to different varieties and growth stages. Generally, this can be done by adjusting the height of lamps and using shade nets.
Ventilation and Humidity
Ventilation and humidity are issues that require special attention when growing short-day plants. Ventilation can prevent pests and diseases and improve air quality, while maintaining humidity can increase air humidity, which is beneficial for plant growth.
Soil Management
When growing short-day plants, the quality and nutrition of the soil are very important for plant growth. Soil with good aeration and rich in organic matter should be selected, and regular fertilization and pruning should be carried out.
Pest and Disease Control
Short-day plants are susceptible to pests and diseases, so regular inspection and cleaning are necessary, and timely control measures should be taken to ensure healthy plant growth.
Water and Energy Saving
When growing short-day plants, attention should be paid to water and energy saving. Methods such as drip irrigation and sprinkler irrigation can be used to reduce waste, while the use of lamps and temperature adjustment can be optimized to reduce energy consumption.
Common Problems and Solutions
When growing short-day plants, some common problems may be encountered, such as yellowing leaves and withered flower buds. For these problems, factors such as light, water, and fertilizer should be adjusted in a timely manner, and corresponding measures should be taken.
When growing short-day plants in a greenhouse or indoors, it is necessary to pay special attention to the control and management of sunlight, while also paying attention to ventilation, humidity, soil management, pest and disease control, etc. Through scientific planting techniques and management methods, these beautiful plants can grow and bloom indoors.
