This test selection in Tonghua Guanghua Town and rhyme Pastoral Co., the 4th bionic operational areas for cultivation experiment , the use of CI-340 -type photosynthesis system , diurnal variation through photosynthesis , light response curve , CO 2 response curve , photosynthesis environmental factors , the role of each influencing factor on photosynthesis and its related physiological effects testing, analysis Schisandra cultivation methods and the bionic artificial cultivation of photosynthetic physiological adaptations of two modes . In addition, in imitation of ecological cultivation mode by fertilization, research fertilizer N, P, K its high growth impact . This test is intended for Schisandra bionic mode photosynthetic physiological adaptation to explore , and through improved forest soil cultivation experiment related to the environment , thereby increasing their height growth . The main conclusions are as follows : 1. Artificial cultivation mode Schisandra a \(2) Light and CO 2 and related physiological response curve test data show that eco- culture model and imitation artificial cultivation mode compared to the LSP, LCP, CSP, CCP and SLM downward trend, while AQY and Chla / b upward trend , indicating that the photosynthetic physiology in terms of Schisandra bionic cultivation patterns showed strong photosynthetic adaptability . 3 main environmental factors affecting photosynthesis to light intensity (PAR), ambient CO 2 concentration , leaf temperature and relative humidity . Artificial cultivation mode of its net photosynthetic rate each factor on the order of magnitude of the impact of air relative humidity > Environment CO 2 concentration > leaf temperature > light intensity (PAR), and its impact bionic cultivation model size order the light intensity (PAR) gt; environmental CO 2 concentration > leaf temperature > air relative humidity . 4.N, P, K effect on height growth effects were : N> K> P. Its N, P, K optimum fertilization was 10.38g / strains , 21.67g / 19.97g strains and strains that 1:0.72:1.3 .
