Reservoir ecological scheduling method considering suitable growth of downstream agricultural crops

Abstract

The invention discloses a reservoir ecological scheduling method considering suitable growth of downstream agricultural crops. A specific crop growth suitability model is established according to statistics of tracking and monitoring data of a specific crop growth period in a reservoir area. Then, the main drainage pipelines of the reservoir are subjected to classified transformation and control.According to the height difference between each drainage main pipe and the planting area, water pumps are installed on the corresponding low-water-level drainage main pipes, electromagnetic valves orwater pumps are installed on the high-water-level drainage main pipes, electromagnetic valves or water pumps are installed on the drainage branch pipes of the planting areas of all the reservoir areasrespectively, the opening degrees of the water pumps or the electromagnetic valves of the different drainage main pipes are controlled, and control over the water temperature and the flow of the drainage main pipes is achieved. According to the optimal temperature and humidity adjustment parameters of different growth periods of crops, different gradients and different water temperatures of the reservoir are regulated and controlled and then injected into the planting area, and then the purpose of regulating and controlling the temperature and humidity of the planting area as the growth environment is achieved. And ecological scheduling of planted crops is carried out through reservoir resources.

Description

technical field [0001] The invention belongs to the technical field of ecological regulation of reservoir resources, and in particular relates to a control technology for realizing favorable growth of crops in the reservoir area by means of regulation and regulation of reservoir water resources. Background technique [0002] The purpose of reservoir construction is irrigation and flood control. Among the various methods of ecological regulation of reservoir resources, most of them aim to achieve ecological regulation by controlling the release of water from the reservoir to improve the living conditions of aquatic organisms in the downstream river. Regarding the use of reservoirs for agricultural irrigation and for the prevention and control of diseases and insect pests, there are no related ecological regulation technology literature records and related application examples. When the reservoir is used for farmland irrigation, the existing irrigation method is mainly to draw...

Problems solved by technology

Low temperature often limits the distribution range of some diseases and insect pests. After the temperature rises, the distribution area of ​​these diseases and insect pests may expand, thus affecting the growth of crops

At the same time, the warming of the ambient temperature also prolongs the growing season of some pests and diseases, increases the number of reproductive generations of pests, prolongs the damage time in a year, and may aggravate crop damage.
