Abstract
The invention discloses a method for promoting the growth of tomatoes by a using a light-emitting diode (LED) light source. The LED light source is red light with the central wavelength of 655nm and the bandwidth of 30nm; and the LED light source is an area light source or a line light source and is arranged within the height range which is 1 to 1.5m away from seeds. The irradiation time and the irradiation intensity of the LED light source are automatically controlled. The method can effectively improve the production quality and the yield of the tomatoes, solve the problem of low production efficiency of the tomatoes, and meet the demand of daily life of people better.
Description
Technical field
The present invention relates to a kind of vegetable growth method, more particularly, relate to a kind of method of utilizing led light source to promote the tomato growth.
Background technology
Tomato is rich in various vitamins, and its nutritive value is very abundant, and it can be cooked and can eat raw, is one of vegetables that people use always in the daily life, is subjected to very much popular favor.Therefore, in the growing tomatoes process, how can further improve its output and quality, improve its production efficiency, just seem of crucial importance.
Summary of the invention
The present invention provides a kind of led light source to promote the method that tomato is grown for solving the problems of the technologies described above, and can effectively improve the quality of production and the output of tomato, overcomes the low problem of tomato production efficiency, better meets the demand of people's daily life.
For achieving the above object, the technical solution used in the present invention is as follows:
Led light source promotes the method for tomato growth, it is characterized in that: described led light source is that centre wavelength is 655nm, bandwidth is the red light of 30nm, and described led light source constitutes area source or line source, and it is installed in apart from seed in 1 meter to 1.5 meters altitude range.
The irradiation time of described led light source and exposure intensity adopt automation control.
Described led light source is that centre wavelength is 655nm, and bandwidth is the red light of 20nm.
In the booth of plantation tomato, employing centre wavelength is 655nm, and bandwidth is that the red LED light source of 30nm shines it, and this led light source can be made area source, also can make line source.The light of this spectral range is in the photosynthetic absorption band of tomato, under the situation of the nutritive value that does not damage tomato, can promote the tachyauxesis of tomato, improves its output.According to the growth rhythm of tomato, the exposure intensity of led light source and irradiation time are carried out remote computer control very convenient use automatically.
Description of drawings
Fig. 1 is a red LED light source light spectrogram among the present invention;
Embodiment
Choose the kind of tomato, soak seed, vernalization, and the soil of plantation tomato is carried out the nutrition preparation.The tomato seeding and growing seedling in soil, is after planting added a cover plastic film.In the booth of plantation tomato, the soil of distance sowing seed is evenly installed some led light sources at 1 meter to 1.5 meters altitude range with certain spacing, this led light source selects centre wavelength at 655nm, and bandwidth is the red light of 30nm, spectral distribution graph as shown in Figure 1.This led light source adopts linear array to arrange.Keep soil temperature more than 20 degrees centigrade, in order to emerging.
Following table be in the tomato process of growth to the rule that requires of temperature:
| Period | Day is warm | Night temperature | Ground temperature |
| Before emerging | 25-30℃ | 16-20℃ | About 22 ℃ |
| Emerge the back to two leaves wholeheartedly | 20-25℃ | 10-15℃ | About 20 ℃ |
| Divide seedling to slow seedling | 25-28℃ | 18-20℃ | About 20 ℃ |
| Slow seedling to seven leaf wholeheartedly | 20-25℃ | 10-15℃ | About 18 ℃ |
| Field planting | 18-22℃ | 5-10℃ | About 14 ℃ |
According to above-mentioned growth rhythm, the irradiation time and the exposure intensity of led light source are carried out automation control by remote computer.
