Abstract

Water hyacinth, also known as water hyacinth aquatic plants native to tropical America. Water hyacinth fibrous roots developed reproductive tillers, landscaping, water purification. Their breeding too quickly, causing serious harm to the ecological environment. On the other hand, the water hyacinth is rich in nutrients and has a very high economic value. Starting from the angle of resource utilization, the combination of the water hyacinth characteristics by analysis of the water hyacinth resource ingredients and organic fertilizer process, developed a series of organic fertilizer high value-added products, and research through the pot and field experiments The biological effects of water hyacinth made of organic fertilizer and application mechanism. The main findings are as follows: 1. Resources component of the water hyacinth analysis results show that the heavy metals in water hyacinth contains rich NPK elements and organic matter, the test taken by water hyacinth plant samples (either stems or roots) within the limits of the range of content in provisions. Ultrasonic extraction of total flavonoids in the water hyacinth, the highest concentrations of up to 43.2 mg / g. Water hyacinth through the the hydrothermal degradation process and made organic fertilizer with a higher amount of humic acid (the highest amount of up to 38.29%) and N, P and K nutrient content (total nutrient content higher than 4.1%), which is a class good ecological organic fertilizer, the development and utilization of value. The the potted test results show that the liquid manure of water hyacinth, water facilities can improve cabbage biomass, nutrient content, Vc and chlorophyll content. Application of water hyacinth mixed fermentation developed organic fertilizer can significantly improve the yield of kidney bean, to effectively improve kidney bean quality, the mainly soluble sugar, crude protein and Vc content, reduce nitrate content. 4. Organic and inorganic fertilizer application developed by mixed fermentation of water hyacinth can promote tomato, radish plants robust growth, significantly increase the yields of tomato, radish, improve the quality of the tomato, radish flavor better. The. Daejeon test results show that the application of water hyacinth can promote organic and inorganic fertilizer Sam the Kom shoot the pumping hair, the performance of Sam Kom total tip amount, average shoot length, branching rate increased significantly. Organic and inorganic fertilizer application of water hyacinth, Ponkan per plant, yield per plant, yield rate were significantly improved compared with the control. Organic and inorganic fertilizer application of water hyacinth in the Sam mandarin fruit mast beneficial to the enlargement of growth, thereby enhancing its fruit weight.
