Study of Light Enviroment and Fertilizer on Leafy Vegetable Growth

[[abstract]]Light environment and fertilizer condition are two important conditions for plant growth, this study leaf cultivation, for example, to plant small plants cultivated environment, respectively to medium soil tillage and planting different hydroponic leafy vegetables, observe and analyze these two conditions on plant growth. First, investigate the effect of ambient light on the leafy plant growth scenario, in two different wavelength LED light board to provide a combination of light needed for photosynthesis of plants were planted way medium soil tillage, planting leafy plant varieties of greens and the mainland sister, the irradiation time is 10 hours; secondly influence research Feipei leafy plant growth conditions on the circumstances, different lighting with a constant number of hours and the nutrient solution pH and is not constant observation light environment combined with the nutrient solution pH change impacts on plant growth, plant hydroponic way, planted leafy plant varieties for the mainland sister and dill spread. Experimental results show that the portion of the light environment, in order to compare the weight of leaf parameters, leaf different light qualityon plant growth, and indeed have a significant impact, with bok choy, for example, the difference of the value of 42%; sister to the mainland cases, the difference was 27%. The results also showed that in some fertilizer conditions, the same weight as a comparison parameter leafy mainland sister 10 hours of light, "the nutrient solution pH constant" than "not constant" weight difference of 15%, 16 h light mainland sister, "nutrient solution pH constant" than 10 hours, "the nutrient solution pH constant" difference of 25%; another 10 hours of light dill spread, "the nutrient solution pH constant" pH than the "non-constant" difference of 8% 16 h light dill spread, "the nutrient solution pH constant" than 10 hours, "the nutrient solution pH constant" difference of 11%. This study also extends leaf cultivation experiences and explore the feasibility of an artificial environment by planting latitude, climate limits the high economic value of herbal plants
