Abstract

The invention discloses a metering irrigation device based on water requirement of crops. The device comprises a water storage tank and a mixing box; the top wall of the mixing box is provided with amotor, a screw feeder, a chemical fertilizer melting tank, a feeding hopper and a water pump with high lift and high flow rate; the outlet section of the feeding hopper extends into the mixing tank, and a flow meter is arranged at the outlet section; the water inlet end of the water pump is connected with a first water inlet pipe extending to the middle and lower part of the purification tank, andthe first water inlet pipe is connected with a second water inlet pipe; the water outlet end of the water pump is connected with a main water delivery pipe through a first water outlet pipe; the connection part of the first water outlet pipe with a sedimentation box and the connection part of the main water delivery pipe with the sedimentation box are both provided with a flow meter; two side surfaces and the top surface of the main water delivery pipe are all provided with water outlet holes; the water outlet on the top of the main water delivery pipe is connected with a water spraying pipe;and the two sides of the main water delivery pipe are connected with burettes, and the bottom surface of each burette is provided with a dripping hole. The irrigation device can realize watering, fertilizing and pesticide spraying, and can accurately measure the total amount of a solution flowing into the main water delivery pipe.

Description

technical field [0001] The invention relates to a crop irrigation system, in particular to a metering irrigation device based on the water demand of crops. Background technique [0002] Irrigation means watering the land with water. The principle of irrigation is that the amount of irrigation, the frequency of irrigation and the time should be determined according to the characteristics of water demand of plants, growth stage, climate and soil conditions, and should be timely, appropriate and reasonable. Its types mainly include irrigation before sowing, irrigation for seedlings, irrigation during the growth period, and irrigation in winter, etc. At the same time, irrigation is a technical measure to supplement the water required by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requiremen...
