Problems solved by technology

[0004] Due to the different water requirements of crops in different growth periods, each time quantitative irrigation is used, there will be problems such as too much water irrigation in a certain period and water waste, and a large water demand in a certain growth period and insufficient irrigation, that is, the existing water output of sprinkler irrigation and micro-irrigation It cannot meet the water demand of each growth cycle of precise crops, and the irrigation effect is poor

Abstract

The invention discloses an irrigation method and device based on crop growth cycle water use features. The irrigation method is characterized in that whether crops are short of water or not in the growth process is judged according to actually measured soil water content, the water demand of the current growth stage of the crops and the rainfall of the coming day, the actual water demand of the crops is calculated if the crops are short of water, a water pump is started in a self-adaptation manner to supply water for the crops according to the relation between the reserve of a reservoir and the actual water demand, and management staff are notified when the reserve of the reservoir is insufficient. By using the method to water the crops, each growth stage the crops can have sufficient water to achieve the optimal growth state of the crops so as to finally increase the yield of the crops, and the safety of a water pump can be guaranteed at the same time.

Description

technical field [0001] The invention relates to agricultural irrigation technology, in particular to an irrigation method and device based on water characteristics of crop growth cycle and real-time weather. Background technique [0002] Water plays an important role in the growth of crops. However, for each growth period of different crops, there are large differences in their water requirements, and the external rainfall only accounts for the required water in the entire crop growth cycle. About a quarter. [0003] At present, when watering crops in China, there are mainly sprinkler irrigation and micro-irrigation (drip irrigation, micro-spray irrigation, small tube outflow irrigation and seepage irrigation), and these two irrigation methods are generally opened manually according to the weather conditions for irrigation, or set to Every set time, automatically start the irrigation equipment for pouring. [0004] Due to the different water requirements of crops in differ...
