Irrigation management system based on irrigation water requirements of corn at different stages and irrigation method

Abstract

The invention relates to an irrigation management system based on irrigation water requirements of corn at different stages. The system comprises a data management module, a data prediction module, acorn variety information base module, a sensor module, an agricultural climatic resource calculation module, an irrigation water requirement calculation module, a year harvest prediction module, a real-time monitoring module, an irrigation strategy generation and execution module. The data management module is connected with the data prediction module, the data prediction module, the corn varietyinformation base module and the sensor module are connected with the agricultural climatic resource calculation module separately, and the agricultural climatic resource calculation module is connected with the irrigation water requirement calculation module; the irrigation water requirement calculation module is connected with the year harvest prediction module, the real-time monitoring module and the irrigation strategy generation and execution module, and the year harvest prediction module and the real-time monitoring module are connected with the irrigation strategy generation and execution module. According to the irrigation management system based on the irrigation water requirements of the corn at the different stages, the agricultural water-using efficiency can be improved, the system helps to reasonably arrange the agricultural production activity, the basic income of farmers is increased, and the system has the important effect on ecological environment protection.

Description

[technical field] [0001] The invention relates to the field of development and utilization of water resources, in particular to an irrigation management system and irrigation method based on the calculation of water demand for corn staged irrigation. [Background technique] [0002] At present, the burning of a large amount of fossil fuels, deforestation and other human activities and industrialization processes have caused serious deterioration of the earth's environment and global changes marked by climate warming, including the retreat of glaciers, the drying up of rivers, the shrinking of lakes, the intensification of desertification, The loss of biodiversity, especially the increasing frequency of drought, has become one of the most common natural disasters in the world. Corn is one of the most widely planted food crops in the world, and it is an extremely important food, feed, and economic crop in China. As one of the most common natural disasters in the world, drought...
