| titleOfInvention | Negative water pressure irrigation and fertilization system and control method |
| abstract | The invention relates to the technical field of agricultural irrigation, and in particular relates to a negative water pressure irrigation and fertilization system and a control method. The negative water pressure irrigation and fertilization system comprises a water source, a fertilizer solution control device and a negative water pressure device, wherein the fertilizer solution control device comprises a fertilizer solution box, a display screen, a sensor and a surfing pump; the fertilizer solution box is communicated with the water source; the display screen is arranged out of the fertilizer solution box; the sensor and the surfing pump are respectively arranged in the fertilizer solution box; the negative water pressure device comprises a liquid storage bucket, a pressure control pipe, a gas collecting bottle and a plurality of ceramic plates; the liquid storage bucket is communicated with the fertilizer solution box; one end of the pressure control pipe is connected with the liquid storage bucket; the other end of the pressure control pipe is connected with the gas collecting bottle; and the gas collecting bottle is communicated with the plurality of ceramic plates. The negative water pressure irrigation and fertilization system is capable of simultaneously supplying moisture and nutrients, and supplying fertilizer solutions with different concentration according to the change of the growth period of the crop, and meets the integrated requirements of growth and development of crops on moisture and nutrient, so that high quality and high yield of the crop are realized. |
