Abstract
The invention discloses a red and blue light quality composition facilitating lettuce growth. The red and blue light quality composition is characterized in that lettuce seeds are placed in a 72-hole tray for seed germination and seedling growth, and LED lamps composed of red light and blue light in different proportions are manually supplemented. By supplementing 7 kinds of red light and blue light in different proportions, the optimal light quality composition is selected out, and thus the optimal lettuce growth effect is achieved, wherein the optimal light quality composition is obtained when the proportion of red light beads to blue light beads is 8:1, and the adopted lettuce variety is Roman Lettuce and purchased from Beijing Beinong Seed Industry Limited Company; by manually supplementing the LED lamps composed of the red light and the blue light in different proportions, lettuce growth is accelerated, and the problem that lettuce growth is poor in dim light is effectively solved.
Description
Technical field
The present invention relates to the red blue light matter composition that is improved Growth of Lettuce, specifically a kind of LED be made up of the red blue light of different proportion artificial supplementation promotes the culture technique of romaine lettuce growth of seedling.
Background technology
Luminous environment is one of environmental factor important in furnished equipments, and it is not only the important sources of photosynthesis of plant energy, is also one of key factor affect fruit formation simultaneously.Compared with open country normal production conditions, facilities environment often because of covering and skeleton structure existence and cause intensity of illumination to reduce, add that winter-spring season intensity of illumination and time are obviously not enough, especially overcast and rainy snow sky, intensity of illumination is even lower than light compensation point, have a strong impact on growing of horticultural crop, caused the continuous decline of yield and quality, constitute the bottleneck problem of China's industrialized agriculture sustainable development.Large quantity research shows, light quality affects the growth and development dynamics of plant.Wherein, the research of Most scholars confirms, the combination that ruddiness closes blue light is more conducive to plant strain growth, but ruddiness and the appropriately combined of blue light more could be conducive to plant strain growth.Romaine lettuce contains minerals and vitamins comparatively horn of plenty, one of important vegetable variety of Ye Shi China cultivation.Although it also can adapt to more weak illumination, the low light level is then unfavorable for its high yield, have impact on the enthusiasm of peasant planting.Therefore, the blue proportioning light quality combination of research Different Red is a kind of effective ways improving romaine lettuce seed germination and growth, meanwhile, further for its applying in furnished equipments provides theoretical foundation.
Summary of the invention
The present invention proposes a kind of red blue light matter composition being conducive to Growth of Lettuce.The present invention is achieved in that a kind of red blue light matter composition being conducive to Growth of Lettuce, it is characterized in that: described romaine lettuce seed is positioned over growth in 72 hole dishes, and the LED be made up of the red blue light of different proportion artificial supplementation realizes.By the red blue light light filling process of 7 kinds of not ratios, select best light quality combination, make romaine lettuce growth of seedling effect optimum, for: the light pearl ratio of ruddiness and blue light is the combination of 8:1; Supplemented the means of specific light quality by external source, effectively facilitate Growth of Lettuce.
The invention has the beneficial effects as follows: under low light condition, artificially feed can promote growing of plant significantly.But the impact of the radiation of different wave length on plant is different.By this research, specify that the light quality combination needed for the growth of applicable Xiaoqinling Nature Reserve.The achievement of this patent can be applicable in the light filling light fixture of industrialized agriculture and plant factor, and for providing theoretical foundation by light quality regulating plant growth; In addition, this patent achievement also can be applicable in the light filling light fixture of Household balcony vegetable plantation, thus realizes the high-quality of home gardening, efficient and standardized production.
accompanying drawing illustrates:
Fig. 1 is experiment LED used;
Fig. 2 is the impact of different light medium light filling on Growth of Lettuce form.
Embodiment:
1, the customization of LED
The LED that this patent uses is purchased in profit Electronic Science and Technology Co., Ltd. of West Germany of Shenzhen, and the power of every lamp is 45W, and operating current is 300mA.Ruddiness (R) and the ratio of blue light (B) are respectively 2/1,4/1,8/1,12/1,1/2,1/4,1/8 (red and blue LED lamp pearl number ratio), and white light is contrast;
2, medical record is tested:
Sprouting test: soak seed seed in warm water 6 ~ 7h, is divided in by the seed soaked and is covered with in the culture dish of two layers of filter paper, uniform discharge 30 in each culture dish, be sowed at after seed shows money or valuables one carries unintentionally in 72 hole dishes, indoor temperature is 28 DEG C.Each process repeats for 3 times, test repetition 3 times;
8 process are established in experiment altogether, are respectively ruddiness (R) and are respectively 2/1,4/1,8/1,1/2,1/4,1/8 with the ratio of blue light (B), and white light is contrast.The light application time of every day is 7:00-19:00, and the average intensity of each process is 250 μm of olm
-2s
-1, temperature is 30 DEG C/20 DEG C, and relative moisture controls about 70%;
The formula of nutrient solution is with reference to Huo Gelan formula.The pH value of nutrient solution controls at 6-7.
Claims (3)
1. one kind is conducive to the red blue light matter composition of Growth of Lettuce, it is characterized in that: the romaine lettuce seed of described growth in 72 hole dishes, through supplementing, the LED that is made up of the red blue light of different proportion realizes, wherein with the most applicable Growth of Lettuce of combination that the light pearl ratio of ruddiness and blue light is 8:1.
2. the red blue light matter composition being conducive to Growth of Lettuce according to claim 1, it is characterized in that: the seed of the 6 ~ 7h that soaks seed in warm water is divided in and is covered with in the culture dish of two layers of filter paper, then be placed in 72 hole dishes and carry out growth test, the LED be made up of different light medium carries out light filling process, the light intensity of each process of strict control, makes it be consistent.
3. the red blue light matter composition being conducive to Growth of Lettuce according to claim 1 and 2, is characterized in that: the romaine lettuce seed be positioned in 72 hole dishes carries out different light medium process, and the light intensity of each process is 250 μm of olm
-2s
-1, wherein with the most applicable Growth of Lettuce of combination that the light pearl ratio of ruddiness and blue light is 8:1.
