Scope

Scope: Liu Yan, Yao Liu Liang, Wang Jian, Zhang Dapeng, Guo Xingwen, and Xu Zhenbin; Main technical content: 1. Integrated water and fertilizer application technology requirements 1.1 Composition of the micro-irrigation fertilization system The micro-irrigation fertilization system consists of water sources, primary hubs, water supply and distribution pipelines, and irrigation nozzles. 1.1.1 Water sources include groundwater, reservoir water, and river water. 1.1.2 Primary hubs include pumps, filters, fertilizers, control equipment, and instruments. 1.1.2.1 Pumps: Select suitable pump types and power according to the water source and irrigation area. For water sources requiring storage or with high sediment content, it is often necessary to build storage tanks. 1.1.2.2 Filters: For groundwater used as an irrigation water source, sieve filters and pleated filters are typically used. The filter size is determined based on the total flow of the drip irrigation pipes in the greenhouse. A single greenhouse should use 3.3 cm or 5.0 cm diameter filters. 1.1.2.3 Fertilizers: Differential pressure fertilizer tanks, Venturi injectors, injection pumps, and open-type waste tanks are used. A single greenhouse should use 30L fertilizer tanks and 4.0 m diameter Venturi injectors. 1.1.2.4 Control equipment and instruments: Valves, flow and pressure regulators, flow meters or water meters, pressure gauges, safety valves, and air inlet/outlet valves should be installed in the system. 1.1.3 Water supply and distribution pipelines The water supply and distribution pipelines are composed of main pipes, branch pipes, and micro-pipes according to the system design. Inside the greenhouse, they consist of branch pipes and micro-pipes, with PE hoses used for branch and micro-pipes. The branch pipe wall thickness is 2 mm - 2.5 mm, with diameters of 32 mm or 40 mm. The micro-pipe wall thickness is 0.2 mm - 1.1 mm, with diameters of 8 mm - 16 mm. 1.4 Irrigation nozzles In
