Problems solved by technology
However, the structure of the fertilization device is relatively complicated, it is not easy to manufacture, and it is troublesome to operate and use. On the other hand, the fertilization device does not accurately quantify the liquid fertilizer flowing out, and there are situations where the flow rate fluctuates, resulting in poor fertilization effect

The invention relates to a pressurized double-tank alternate quantitative fertilization device for drip / spray irrigation, which includes a sealed liquid storage tank and a pressurizing unit communicating with the inside of the liquid storage tank. The liquid storage tank extends out of the water pipe from the inside. There are two, the pressurization unit communicates with the two liquid storage tanks at the same time, the outlet pipes of the two liquid storage tanks are connected with the fertilization pipeline at the same time, and the fertilization pipeline includes a filter connected through the infusion pipe, a liquid regulating valve and a flow rate count. Compared with the prior art, the present invention can inject a quantitative amount of liquid fertilizer into the water pipe to control the amount of fertilizer application; it can realize the function of uninterrupted cycle fertilization, and after the liquid in one liquid storage tank is discharged, the other liquid storage tank is discharged At this time, filling the previous liquid storage tank with fertilizer liquid can make the device run uninterrupted, greatly save labor costs, and improve fertilization efficiency. The invention has the characteristics of simple structure, reliable performance, low cost and easy operation, and is suitable for the current actual conditions in most rural areas of our country.
Description
technical field [0001] The invention relates to a fertilization device, in particular to a pressurized double-tank alternate quantitative fertilization device for drip / spray irrigation suitable for farmers with small land areas. Background technique [0002] Water-soluble fertilizers refer to fertilizers that can be completely dissolved in water. Compared with fertilizers and slow-release varieties that are partially dissolved in water, such as calcium superphosphate and granulated compound fertilizers, they are quick-dissolving, high absorption rate, quick-acting, and residue-free. The obvious advantages such as convenient application have developed rapidly in China in recent years, especially in the face of the increasingly serious environmental protection and water shortage brought about by the greenhouse effect, the drip irrigation system and spray irrigation have significant advantages. New fertilization methods with water-saving functions have begun to be valued and pr...
