LED灯模拟作物间作套种群体内光环境的设计与应用
Design and effect of LED simulated illumination environment on intercropping population
摘要
Abstract
Simulating effectively illumination environment indoor for the compound crop population is the basis for further study on molecular mechanism of intercropping system. Therefore a light-emitting diode (LED) lamp was designed as the light source for cultivating plant indoor. Three high powered LEDs, blue, red and far-red light which has most impact on crop growth were selected to compose the LED panel by a ratio of 1:3:3 in order to provide an uniform lighting; cooling fin, air passage and fan were used to cool the LED panel; PWM method was adopted to regulate the radiation intensity continuously and respectively. Moreover, maize-soybean relay strip intercropping system was employed to test the performance of the LED lamp by imitating two different light environments in line with the natural and two-crop-compound light environment in field while the light environment and crop growth indexes were measured; and the results show that the light environment of relay strip intercropping system was simulated suitably with the LED lamp; the light was uniform; the soybean grew in order and exhibited typical shade-avoidance responses.关键词
