Description

Efficient water and fertilizer integrated irrigation and fertilization system Technical Field The invention relates to the technical field of fertigation, in particular to a high-efficiency water-fertilizer integrated fertigation system. Background The integration of water and fertilizer is a new mode of agricultural irrigation, which pre-dissolves fertilizer in a water body and then irrigates. The water and fertilizer integrated technology is that the water and fertilizer integrated technology is used for fertilizing by an irrigation system, and crops absorb the nutrients while absorbing the moisture. The fertilization which is usually carried out simultaneously with irrigation is carried out by injecting a fertilizer solution into an irrigation water pipeline under the action of pressure. The irrigation water with fertilizer is sprayed onto crops or dripped into root zone via irrigator (nozzle, micro nozzle, dripper, etc.). In a broad sense, the fertilizer is applied after being dissolved, including spraying, watering, spraying, pipeline application and the like, and the novel agricultural technology integrating irrigation and fertilization is referred to. The water and fertilizer integrated method is characterized in that a pressure system (or natural fall of terrains) is used for integrating soluble solid or liquid fertilizer, the blended fertilizer liquid and irrigation water are supplied with water and fertilizer through a controllable pipeline system according to the fertilizer requirement rules and characteristics of soil nutrient content and crop types, after the water and fertilizer are fused, sprinkling irrigation or drip irrigation is formed through a pipeline and a drip irrigation head, the growing areas of crop root system development are uniformly, regularly and quantitatively infiltrated, the soil of the main root system is always kept loose and proper water content, meanwhile, according to the fertilizer requirement characteristics, soil environment and nutrient content conditions of different crops, the water requirement in different growth periods is designed according to the fertilizer requirement rule conditions of the crops, the water and the nutrients are regularly and quantitatively supplied to the crops in a certain proportion. The water-fertilizer integrated technology is a new agricultural technology integrating irrigation and fertilization, and is characterized in that a pressure irrigation system is used for accurately conveying a soluble solid or liquid fertilizer to the root soil of crops according to the nutrient content of the soil, the fertilizer requirement rule and the fertilizer requirement characteristic of the planted crops, and the blended fertilizer liquid and irrigation water together so as to meet the requirement of crop growth. In popular terms, the water and fertilizer integrated technology is irrigation and fertilization technology, and is designed according to the growth and development requirements of crops and is used for providing water and nutrients quantitatively, regularly and proportionally for the crops. The water and fertilizer integrated technology is implemented, a fixed water source which has good water quality and meets the micro-irrigation requirements, such as a river, a reservoir, a motor-pumped well and the like, and a complete pressure irrigation system, such as drip irrigation and spray irrigation, are required. The irrigation system has motor, water pump, filter, protector, water pipeline, fertilizer applicator and control and measuring equipment. The current water and fertilizer integrated technology is mainly applied to greenhouse, orchards, open-field vegetables and other crops with good economic benefits. The process by which fertilizer is introduced into the field along with irrigation water is called fertigation. The fertilizer is accurately supplemented and uniformly applied near the root system according to the nutrient requirements, the climatic conditions and the like of each stage of crop growth while irrigation is performed by drip irrigation, underground drip irrigation and the like, and is directly absorbed and utilized by the root system. The intelligent water and fertilizer integrated irrigation system can automatically detect, allocate and supply water and fertilizer according to the water and fertilizer requirement rules of different crops, soil environment and nutrient content conditions, and realize timing and quantitative control of irrigation and fertilizer application while improving irrigation water efficiency, so that water and fertilizer can be saved, labor investment can be reduced, and labor cost can be reduced. The current fertigation system generally combines main pipeline and lateral pipeline to realize the fertigation operation of large tracts of land crops, but the liquid manure is flowed more to the lower back flow, is difficult to guarantee that all crops obtain the fertigation of same degree and handles, c
