Water and fertilizer medicine integrated control method with weather changes

Abstract

The invention discloses a water and fertilizer medicine integrated control method with weather changes. The water and fertilizer medicine integrated control method includes 1), acquiring meteorological data and judging whether agricultural activities are suitable or not according to the meteorological data; 2), extracting core meteorological elements from the meteorological data and calculating affecting weight of the meteorological elements on the specific agricultural activities; 3), according to the affecting weight, modifying default values of topdressing time, insecticide spraying time, water intake time and hydrating time set in each period of specified planting objects of the agricultural activities; 4), according to modified topdressing time, insecticide spraying time, water intake time and hydrating time, controlling opening and closing of an electric water valve to complete the control process. With the method, fertilizing, insecticide spraying and watering can be accurately realized by infusing meteorological information to the control process, so that the process is more refined and intelligent, and the influence of chemical raw materials on the environment can be reduced to the greatest extent.

Description

technical field [0001] The invention relates to an integrated control method of water and fertilizer, in particular to an integrated control method of water, fertilizer and medicine that changes with the weather. Background technique [0002] Water and fertilizer integration technology is a new agricultural technology that integrates irrigation and fertilization. The good effect of (increasing production, increasing income, and increasing efficiency) is the "No. 1 technology" for developing modern agriculture and accelerating the transformation of agricultural development methods. [0003] At present, the water and fertilizer integrated control unit on the market adopts the three-definite working mode of fixed parameter configuration, start timing, and fixed times; the method of using it is to store in the storage module the corresponding water consumption and consumption of different root system lengths of different crops during the growth period. Fertilizer quantity; the ...

Problems solved by technology

[0003] At present, the water and fertilizer integrated control unit on the market adopts the three-definite working mode of fixed parameter configuration, start timing, and fixed times; the method of using it is to store in the storage module the corresponding water consumption and consumption of different root system lengths of different crops during the growth period. Fertilizer quantity; the counter and timer are connected to the controller to realize the start of the water pump and the fertilizer pump at a fixed time and at a fixed number of times; once the fixed number and timing are configured, they cannot be adjusted in real time according to the change of the weather, even if there is an obvious precipitation process tomorrow , the whole process must also be completed according to the set method; this three-determined mode has to deal with different planting objects and different planting regions, etc., the control unit configuration information is large, and it is inconvenient to modify the control parameters on site

Moreover, it is also necessary to face the problem that users must modify and reconfigure parameters when changing varieties; in short, this mode adopts the control process and control scheme set in advance, and the operator starts it once and then automatically completes all the set work processes. ; This mode of working according to the pre-set process regardless of the constant changes in weather conditions and the actual conditions of crop growth, after years of practice, is becoming less and less suitable for the needs of modern agricultural development
