Environment Evaluation and Analysis of Multi-span Plastic Greenhouse for Tobacco Floating Seedlings in Guizhou
摘要
Abstract
To control the environment factors and set artificial light scheme reasonably in multi-span plastic greenhouse used for tobacco seedling, based on the environment needed by flue-cured tobacco seedlings in different growth periods, the inside and outside environment factors and the light intensity change between seedling frame layers were tested and analyzed in Guizhou typical tobacco floating seedling plastic greenhouse. The result showed that the highest temperature could reach 25℃in sunny day, but in cloudy day, it was only 15.3℃, the relative humidity changed from 40%to 90%, and the light intensity range was 50 to 5000μmol/(m2·s), which were fit for tobacco seedling growth. When using the three-dimensional seedling frame with 6 layers, the light intensity range of the first to the fourth layer was 5-90μmol/(m2·s), and light intensity of the fifth and the sixth layer reached 40-350μmol/(m2·s), which showed that the natural light on the top two layers was enough for seedling growth, but added artificial light was needed from the first to the fourth layer. This experiment can provide theoretical proof for reasonable environment adjustment and artificial light scheme.关键词
