Orchid cultivation technology lighting
The use of electric light sources to artificially supplement the light is a good way to improve the cultivation of orchids and achieve high yields and fine orchids. Through the beginning of the experiment, the best conditions for the artificial supplemental lighting required for the development of Chunlan have been found, and the budding rate is better than natural environmental protection. It is twice as high and has improved the appreciation value of Lanyin.
1. Artificial supplemental light source design;
The first category is to add light sources for mutual assistance. Four 20-Watt fluorescent tubes can be installed at 200mm above the orchid plant and applied before sunrise, sunset and lack of sunlight. The second category is the light source to kill germs. A 30-watt ultraviolet (2,537 angstrom) tube was installed and installed at a height of 400 millimeters above the bluegrass, once a week for 15 minutes.
2. Extended light mutual aid time;
The proper addition of light is particularly beneficial to the nutrient development of orchids, but the duration of light cannot be too long. The resume of the author is: Daily light hours, 4 hours in the spring, 2 hours in the summer, 3 hours in the spring, 5 hours in the summer, and the light is added for about 3.5 hours every day throughout the year.
3. The best light intensity for mutual assistance;
Although Chunlan is a shade-tolerant plant, it also requires a certain amount of light intensity to develop normally. Its best light intensity is 2000 lux. Light is too strong and too weak orchids can not be normal development and development.
