Solar-driven control of water, fertilizer and gas integrated gap steady flow soaking irrigation system

Abstract

The invention relates to a gap steady flow wetting irrigation system with integration of water, fertilizer and gas driven and controlled by solar energy. A solar photovoltaic panel is installed above the push-pull type micro car rack, a liquid fertilizer bucket, a storage battery, a micro draught fan and an electrically controlled micro booster pump which is used for applying liquid fertilizer are arranged in the rack body, a variable flow state adding fertilizer and adding gas special pipe communicated with the micro booster pump an outlet of the micro draught fan behind the micro car, field water-saving irrigation water ducts are installed at the two ends of the variable flow state adding fertilizer and adding gas special pipe in a connected mode, and multiple field irrigation pipe network branch pipes, an irrigation pipe network capillary tube and a gap type steady flow irrigation emitter are connected to the field water-saving irrigation water ducts in sequence in a subordinated mode to form a complete gap steady flow wetting irrigation system with the integration of the water, the fertilizer and the gas driven by replenishable charging with solar energy and a big power grid. The gap steady flow wetting irrigation system with the integration of the water, the fertilizer and the gas driven and controlled by the solar energy is simple in structure, convenient to operate, mobile or fixed to use, and applicable to wetting irrigation systems of fruit trees or water-fertilizer-saving micro irrigation of soil at roots of other crops.

Description

technical field [0001] The content of the invention belongs to the technical field of water, fertilizer and gas integrated irrigation system for facility agriculture, and relates to a comprehensive water-saving irrigation system that uses renewable energy to drive and control water, fertilizer and gas. Integrated crevice steady flow soaking irrigation system, its products are suitable for water-saving and fertilizer-saving micro-irrigation of fruit tree soaking irrigation system or root soil of other crops. Background technique [0002] In order to improve the modernization of agricultural production, save water and fertilizer resources and promote production increase, in recent years, the national agricultural water conservancy department is vigorously advocating and supporting the integrated technology of water and fertilizer. Faster and more types. According to the survey, the currently known equipment for adding liquid fertilizers for planting vegetables and orchards in...

Problems solved by technology

The above-mentioned various types of water and fertilizer mixing equipment and water-saving soaking irrigation and micro-sprinkler irrigation systems have different advantages, but there are still some shortcomings in application, which cannot meet the actual needs of today's production. For example, many farmers have responded that due to the long agricultural production cycle and low profit , the current electric-driven large and medium-sized water and fertilizer mixers are large in size, single in function, and troublesome to move, and most of them are powered by agricultural power grids, and need to pull special power supply lines, resulting in expensive prices and high investment costs. The area is large, and it is not suitable for sub-contracting orchards of different scales; although there are some small-scale immersion irrigation and micro-sprinkler irrigation systems, due to the low water pressure of such systems, the water flow rate in the pipe is relatively slow, for example, differential pressure injection liquid fertilizer or Venturi tube suction immersion irrigation and micro-sprinkler irrigation systems, etc., the fertilization is not stable

[0003] On the other hand, according to the theoretical analysis of atmospheric water evaporation and climate correlation, many fruit and vegetable gardens in Northwest my country are located in arid or semi-arid areas. Due to the lack of design for adding air to the water-fertilizer mixture in the pipe, the existing section When the drip irrigation of the water micro-irrigation system drops water droplets, oxygen is automatically released in the air, which is equal to no air addition, and the drip irrigation water droplets are very small, dripping on the ground, because the sun and dry areas are affected by the dry climate, the surface water is easily evaporated, resulting in waste , the above-mentioned problems are also problems that the majority of farmers are eager to solve
