Studies Coptis Chinensis Franch Of Different Illumination On The Impact Of Quality And Yield

Coptis chinensis Franch is a kind of Like-shady plant,most of the periods of its growth for manual growing needs overshadow.it con not be Shined by Direct sunlight, and with increasing of growth time, the demand for light- Strength will be changing. That is front time for like-shady, late time for like_sunshine..Light is the most important factor for environment.as the major Energy Source for Photosynthesis,light not only provides enery for plant , also change of Irradiance , Photoperiod and Light quality could affect its Growing metabolic . So far ,effect of light quality on quality and yield and Physical features of coptis chinensis Franch has never be Reported. in view of the present situation, by processing Coptis chinensis Franch of three year for different light quality, different shading and different shade modes, the paper has researched effect on growth , physiology ,quality and yield in different conditions, so as to find the technical measures that how to improve quality and yield, providing theory evidence for high qulity and yield of Coptis chinensis Franch.Here is the main research issue.1. Effects of light quality on quality and yield of coptis chinensis Franch.: Dealing with it under redlight , three kinds of Alkaloid Content has greatly improved, the menace action is appropriate. And The growth speed is higher, also the yield of roots is higher, there is no significant difference in plant yield as contrast.2. Effects of light quality on quality and yield of coptis chinensis Franch: if dealing it with Shade net(80%) ,the yield is higher than other ways, Alkaloid Content is also higher. By comprehensive comparison, the most suitable condition for three year coptis chinensis Franch growing is 80%Shade net.3. Effects of different shading on quality and yield of coptis chinensis Franch :the mode for highest yield is Fructus schisandrae shading systems , middle is Shade net 80% mode,there is no significant difference between undergrowth mode and Shade net 80% coverage mode. For alkaloids concentration , Fructus schisandrae shading mode is the most high, then the undergrowth mode, there is no significant difference between undergrowth mode and Shade net 80% coverage mode.In short, the best choice for planting mode of Coptis chinensis Franch in zhenPing is ecological cultivation, i.e.,using Fructus schisandrae shading systems, by each other forward intercropping, to produce higher economic benefit and higher qulity ,higher yield of Coptis chinensis Franch.and during the years of not -gained for Coptis chinensis Franch, harvest for Schisandra chinensis could efficiently make up the defect of Coptis chinensis Franch long Growth Circle. Before Schisandra chinensis's Groups-growth, you could also choose shade net (80%) take the place of Fructus schisandrae shading ,until Schisandra chinensis's Groups-growth,you can remove the shade net; in some areas unfit for planting Schisandra chinensis, it could direct ly use shade net (80%) for Coptis chinensis Franch planting. For choosing shade net, it can be red ,for improving quality and yield of Coptis chinensis Franch further more, it's not a good suggestion for undergrowth or Simple shading, so as not to damage the ecological environment .
