Water-fertilizer-integrated irrigation system for container plant factory

Abstract

The invention discloses a water-fertilizer-integrated irrigation system for a container plant factory. The water-fertilizer-integrated irrigation system comprises a fertilizer sucking system, a fertilizing system and a control system, wherein the fertilizer sucking system comprises a stock solution storage device, a fertilizer sucking device and a mixing device; the fertilizing system comprises afertilizing power device, a fertilizing pipeline and a plant growth rack which are connected with one another; the fertilizer sucking device comprises a fertilizer sucking pipeline and a Venturi fertilizer sucking valve arranged on the fertilizer sucking pipeline; a flow metering device is arranged in the mixing device; the control system comprises a man-machine interaction computer, a detecting module and an executing module, the detecting module is arranged in the mixing device, and the executing module controls the on and off of the fertilizer sucking system and the fertilizing system. Thewater-fertilizer-integrated irrigation system has the advantages that the Venturi effect is utilized to provide fertilizer sucking power; the water-fertilizer-integrated irrigation system is high in durability, low in maintenance cost, small in floor space and suitable for the limited and narrow space of the container; by the control system, man-machine interaction is achieved, and the irrigationprocess is intelligent and controllable.

Description

technical field [0001] The invention relates to the field of agricultural facilities, in particular to a water and fertilizer integrated irrigation system for container plant factories. Background technique [0002] Water and fertilizer integration technology is a new agricultural technology that integrates irrigation and fertilization. It can formulate reasonable irrigation solutions according to the water and fertilizer requirements of crops, and carry out irrigation operations. It can effectively achieve a uniform ratio of water and fertilizer, on time and in volume Irrigate crops efficiently, meet the water demand of crops, and at the same time realize water-saving irrigation. The currently used plant irrigation systems have disadvantages such as easy to cause blockage, low degree of intelligence, and inaccurate nutrient ratio. Contents of the invention [0003] The technical problem to be solved by the present invention is that the present invention provides a new co...
