Description

Technical Field

[0001] The utility model relates to the field of drip irrigation and fertilization, in particular to a water-fertilizer integrated device capable of quantitative drip irrigation and fertilization. Background Art

[0002] Integrated water and fertilizer means that with the help of a pressure system (or natural terrain height difference), soluble solid or liquid fertilizers are mixed according to the soil nutrient content and the fertilizer requirements and characteristics of the crop type, and the fertilizer liquid is mixed with irrigation water through a controllable pipe system to supply water and fertilizer. After the water and fertilizer are mixed, drip irrigation is formed through pipes and drippers to evenly infiltrate the crop root development and growth area.

[0003] However, most of the integrated water-fertilizer devices now only have the function of fertilizing during use, and cannot fertilize in a quantitative manner. If too much fertilizer is applied, it will cause a waste of resources and damage the soil structure. If too little fertilizer is applied, it will cause insufficient nutrition for crops and affect the growth of crops. In addition, excessive chemical fertilizers will cause overnutrition for crops, causing crop necrosis and affecting crop yields.

[0004] Therefore, we propose a water-fertilizer integrated device that can perform quantitative drip irrigation and fertilization in order to solve the above-mentioned problems. Utility Model Content
