The invention relates to the field of irrigation, and provides a greenhouse water and fertilizer integrated cluster irrigation method and irrigation system. The greenhouse water and fertilizer integrated cluster irrigation method and irrigation system comprises the following steps: determining the number of irrigation areas and the number of irrigation points in each irrigation area; determining the irrigation concentration of each irrigation area; starting irrigation from an irrigation point in the irrigation area corresponding to the minimum irrigation concentration in the order of increasing irrigation concentration; jumping to an irrigation point corresponding to the next irrigation concentration when irrigating to the last irrigation point corresponding to the concentration, and irrigating until retaining the last irrigation point corresponding to the irrigation concentration; and jumping to completing the irrigation of the last irrigation point corresponding to the minimum irrigation concentration in the reverse order of from large irrigation concentration to small irrigation concentration until completing the irrigation of the last irrigation point corresponding to the maximum irrigation concentration, and ending the irrigation. The invention can minimize the amplitude and number of jumps in target concentration in the process of irrigation and fertilization, so as to minimize the crop yield reduction caused by the fluctuation of the concentration of the output fertilizer liquid of a greenhouse water and fertilizer integrated machine.
Description
technical field [0001] The invention relates to the technical field of greenhouse water and fertilizer integrated irrigation, in particular to a greenhouse water and fertilizer integrated cluster irrigation method and an irrigation system. Background technique [0002] my country is a big country in the production and use of chemical fertilizers, and it is also a country with a high shortage of water resources. Vegetables and other horticultural crops with high added value have a low water and fertilizer utilization rate, and excessive fertilization and excessive irrigation are more common, resulting in a gradual increase in agricultural production costs, a continuous deterioration of the agricultural ecological environment, and a threat to the safety of vegetable products. [0003] As the function of precise fertilizer distribution and automatic irrigation, the greenhouse automatic water and fertilizer integrated machine is the core device that can be popularized and applie...
