42results about How to "Maximize fertilizer efficiency" patented technology

The invention discloses a preparation method of an organic fertilizer and a preparation method of an organic-inorganic biochar compound formula fertilizer. The preparation method of the organic fertilizer provided by the invention comprises the following steps: (1) mixing organic matters and biochar to obtain a premix; (2) controlling the water content of the premix to be 10%-50%; (3) adding an organic matter degrading enzyme into the premix treated in the step (2); (4) adding a biodegradation agent into the mixture obtained in the step (3); and (5) carrying out composting fermentation on the mixture obtained in the step (4) to obtain the organic fertilizer after the fermentation is finished. According to the compound formula fertilizer disclosed by the invention, plant-source and animal-source organic matters are mixed and fermented, and the raw materials are subjected to innocent treatment to form biochar, so that the adsorption effect of the biochar is exerted, and a clean organic fertilizer is produced; nitrogen, phosphorus and potassium fertilizers are balanced and reasonably formulated according to organic matters from different sources, so that the fertilizer efficiency is maximized.

A farmland balance regulation system and an agricultural wetland circulation system. The invention relates to the technical field of eco-agriculture. The farmland balance regulation system includes, in a successively communicated manner, an irrigation water pretreatment system, a farmland shallow water wetland system, an ecological ditch, and a region multi-pool system. The irrigation water pretreatment system includes, in a successively communicated manner, a primary settling tank, a mixing and blending tank, and a lifting and water distribution system. A detection system is arranged in the mixing and blending tank. The agricultural wetland circulation system includes farmlands and a water distribution system. The water distribution system includes a water inlet pipe, a water distribution pipe system, and a water outlet pipe. The water inlet pipe is communicated with the water distribution pipe system. The water distribution pipe system and the water outlet pipe are arranged in the farmlands. The water outlet pipe is provided with a water level control valve. The ecological ditch includes a bottom wall, a first side wall, and a second side wall. Aquatic plants are planted on the bottom wall. Baffle plates are arranged in the ecological ditch at interval in the water flowing direction. A water flowing gap is formed between the bottom wall and the baffle plates. The region multi-pool system includes a plant facultative pool. The agricultural wetland circulation system includes the farmland balance regulation system. The two systems can achieve recycling utilization of irrigation water, thereby saving water source.
