Method and system for predicting irrigation flow according to climate change

Abstract

The invention relates to the technical field of irrigation prediction, and provides a method and a system for predicting irrigation flow according to climate change. The system comprises a historicaldatabase, a climate prediction database, an on-site acquisition sensor and an irrigation water volume prediction and correction module. The method comprises the following steps: obtaining weather prediction data from a network according to original historical irrigation water volume data; calculating predicted irrigation water volume, and correcting the predicted irrigation water amount by using the field environment data; finally, acquiring the actual irrigation water amount, adding climate change factors to the basis of the crop irrigation flow, predicting the irrigation flow of different crops, and designing intelligent irrigation flow prediction according to the climate factors, so the defects of existing consistent quantitative irrigation can be overcome, and water supply is more reasonable.

Description

technical field [0001] The invention relates to the technical field of irrigation forecasting, in particular to a method and system for forecasting irrigation flow according to climate change. Background technique [0002] In order to ensure the normal growth of crops and obtain high and stable yields, it is necessary to give sufficient water to the crops to promote growth. With the continuous strengthening of scientific and technological power, automatic irrigation of crops has been realized, which improves the disadvantages of manual irrigation, saves manpower, and improves irrigation efficiency. [0003] But not all crops need the same amount of water. Some crops will reduce their yield if they have too much water, and the change of climate environment is also inseparable from the amount of irrigation water. Therefore, for the change of climate environment and the crop itself It is very important to give proper irrigation flow rate according to the growth state. Content...
