【摘要】：農(nóng)業(yè)的生產(chǎn)活動與光有著密切聯(lián)系，傳統(tǒng)的農(nóng)業(yè)照明光源有著效率低、高功耗、利用率低等缺點(diǎn)，尋找新型替代光源成為農(nóng)業(yè)領(lǐng)域急需解決的問題。近些年LED技術(shù)飛速發(fā)展，LED紅光、藍(lán)光等大功率LED器件生產(chǎn)成本的下降，專家學(xué)者圍繞LED光源在農(nóng)業(yè)中應(yīng)用，進(jìn)行了不懈的研究，并取得了突破。LED光源相比與傳統(tǒng)農(nóng)業(yè)照明光源有壽命長、體積小、耗能低、波長固定與低發(fā)熱等優(yōu)點(diǎn)，而且LED光源光譜可配置能夠滿足植物生長需求。通過研究LED光源在農(nóng)業(yè)上的應(yīng)用，為LED植物生長照明光源的改進(jìn)以及LED光源在植物培育以及現(xiàn)代農(nóng)業(yè)生產(chǎn)中的的應(yīng)用具有重要意義。 根據(jù)目前我國植物生長LED照明市場的現(xiàn)狀，植物生長LED照明技術(shù)相發(fā)展相對滯后，在前人研究的基礎(chǔ)上，從植物生理學(xué)需光性分析出發(fā)，植物主要吸收紅橙光(波長595nm~700nm)，，藍(lán)紫光(波長370nm~435nm)用于光合作用。根據(jù)植物生長需求選用1W大功率LED器件。并運(yùn)用TracePro軟件建立LED植物生長燈模型，進(jìn)行仿真觀察植物生長LED控制照明系統(tǒng)在照度分布，光強(qiáng)分布上的特點(diǎn)。運(yùn)用照度公式結(jié)合斯派羅法則計算確定符合均勻光照的LED燈間距。根據(jù)仿真結(jié)果以及計算結(jié)果設(shè)計LED植物生長照明模塊。選用穩(wěn)定高效的智能驅(qū)動IC，并結(jié)合STM32主控芯片移植嵌入式操作系統(tǒng)對所設(shè)計的LED植物生長照明系統(tǒng)進(jìn)行手動調(diào)光以及模擬日升日落模式控制。將設(shè)計好的LED植物生長照明系統(tǒng)用于油菜培養(yǎng)實驗，探求該LED植物生長照明系統(tǒng)在植物照明領(lǐng)域的效用，最終達(dá)到提升植物品質(zhì)，降低植物培育的運(yùn)行成本。 通過手持光譜儀對該LED照明模塊進(jìn)行光譜測試與光照度測試，通過測試結(jié)果可以得知，植物生長LED照明系統(tǒng)的光譜范圍與植物葉綠素吸收光譜范圍完全吻合。功耗方面較傳統(tǒng)農(nóng)業(yè)照明燈具更低。 在油菜的培育實驗中可以看出，采用該照明系統(tǒng)培育出的油菜與自然光培育下的油菜基本無差別，從而說明該植物生長LED照明系統(tǒng)能夠應(yīng)用于植物生長照明領(lǐng)域。
[Abstract]:Agricultural production activities are closely related to light. Traditional agricultural lighting sources have the disadvantages of low efficiency, high power consumption, low utilization rate, etc. In recent years, the rapid development of LED technology has led to the rapid development of LED red light, blue light and other high-power LED devices production costs decline, experts and scholars around the LED light source in agriculture, This paper has made unremitting research, and has achieved the advantages of long life, small volume, low energy consumption, fixed wavelength and low heating compared with the traditional agricultural lighting source. And the spectrum of LED light can be configured to meet the needs of plant growth. By studying the application of LED light source in agriculture, It is of great significance for the improvement of LED light source for plant growth and the application of LED light source in plant cultivation and modern agricultural production. According to the current situation of LED lighting market in China, the development of plant growth LED lighting technology is lagging behind. Based on the previous studies, the light requirement of plant physiology is analyzed. The plant mainly absorbs red orange light (wavelength 595 nm) and blue violet light (wavelength 370 nm ~ 435 nm) for photosynthesis. According to plant growth requirement, 1 W high power LED device is selected. The model of LED plant growth lamp is established by TracePro software. The illumination distribution of plant growth LED controlled lighting system was observed by simulation. The characteristics of light intensity distribution. Using illumination formula combined with Spiro's rule to calculate the spacing of LED lamp with uniform illumination. According to the simulation results and calculation results, the LED plant growth lighting module is designed, and a stable and efficient lighting module is selected. It can drive ICs and transplant embedded operating system with STM32 master control chip to control the designed LED plant growth lighting system by manual dimming and simulating sunrise and sunset mode. The designed LED plant growth lighting system is used in rape culture experiment. The utility of the LED plant growth lighting system in the field of plant lighting was explored to improve the plant quality and reduce the operation cost of plant cultivation. The LED illumination module is tested by the hand-held spectrometer, and the results show that, The spectral range of plant growth LED illumination system is in good agreement with the absorption spectrum range of plant chlorophyll, and the power consumption is lower than that of traditional agricultural lighting lamps. In the experiment of rapeseed cultivation, it can be seen that there is no difference between the rape cultivated by this illumination system and the rape cultivated by natural light, which shows that the LED illumination system for plant growth can be applied to the field of plant growth lighting.
