Water and fertilizer integration technology is a new agricultural technology that combines fertilization and irrigation. It is a watering device that is installed on the final pipeline through a low-pressure pipeline system and a water-filler installed on the final pipeline. The water containing soluble fertilizer can be directly and accurately delivered to the soil surface or soil layer near the root of the crop at a small flow rate. Water and nutrients are directly supplied to crops according to crop growth requirements, quantitatively and regularly. Its characteristic is that it can accurately control the amount of irrigation and the amount of fertilizer applied, and significantly improve the utilization rate of water and fertilizer. Compared with the traditional technology, the technology saves 30% to 35% of vegetables and 40% to 45% of fertilizers; the orchard saves 40% and the fertilizer is 30%. Vegetable production increased by 15% to 22%, and fruit production increased by 9% to 15%.
1. Plan and configure micro-irrigation and fertilization system equipment according to the area and shape of the plot. Micro-irrigation and fertilization system consists of water source (according to GB5084-92 "land water quality standard for farmland irrigation"), first hub (pump, power machine, fertilization system, filtration equipment, control valve, etc.), water distribution network (including main pipe, branch pipe, capillary tube) Three-stage pipeline), emitter (divided into dripper, drip irrigation pipe, micro-nozzle, small pipe emitter, seepage pipe, water spray belt, etc.) and flow, pressure control components and measuring instruments.
2. The fertigation program is determined. According to the crop and its growing conditions, the irrigation system (including irrigation quota, irrigation time, irrigation period, irrigation times and total irrigation amount) and fertilization system (adding time, quantity, proportion, number of fertilizers and total amount) are determined.
3. Select the applicable fertilizer variety. One is a liquid fertilizer with a suitable nutrient content, the other is a solid fertilizer for micro-irrigation, and the third is a solid solid fertilizer with good solubility. According to the reaction with irrigation water, configure the proportion and quantity of fertilizer.
4. According to the climate, crop growth, etc., refer to the fertilization program, implement irrigation and fertilization in a timely manner, and strengthen field management.
