Plant irrigation decision-making system and method

Abstract

The invention provides a plant irrigation decision-making system and a method. The plant irrigation decision-making system comprises water potential instruments, a power supply device, a liquid flow meter, a data collector and a processing terminal. The water potential instruments are fixed to the base end and the top end of a to-be-measured plant and the base end and the top end of a reference plant; the liquid flow meter is fixed on the to-be-measured plant and the reference plant; water potential and transpiration water consumption rate collected by the water potential instruments and the liquid flow meter are forwarded to the processing terminal after being collected by the data collector; and the power supply device supplies power to the water potential instruments and the liquid flow meter. According to the plant irrigation decision-making system and the method, the moisture condition of the plant can be accurately monitored for a long time under the condition that the plant is not destructively damaged.

Description

technical field [0001] The invention relates to the technical field of irrigation decision-making, in particular to a plant irrigation decision-making system and method. Background technique [0002] With the intensification of water demand from industry, environment, municipal and service industries, irrigated agriculture is under great pressure to reduce water use, while maintaining high yields. One strategy under current research is Regulated Deficit Irrigation (RDI), which aims to achieve higher water productivity through precise, differentiated irrigation throughout the crop growth period based on the drought sensitivity of the crop at each growth stage. [0003] Real-time and accurate monitoring of crop moisture status is crucial for implementing RDI to guide irrigation decisions and optimize irrigation regimes. Current methods for obtaining information on crop water status mainly rely on measurements of soil moisture or are based on simple methods to calculate crop w...

Problems solved by technology

[0006] The invention provides a plant irrigation decision-making system and method, which are used to solve the defects that the parameter measurement in the existing irrigation decision-making method will cause destructive damage to the plants and cannot accurately indicate the water status of the plants for a long time. The flow meter is a non-destructive sensor that collects the water potential and transpiration water consumption rate of the plant, and then determines the water status of the tested plant based on the collected water potential and transpiration water consumption rate of the tested plant and the reference plant, and adjusts the current irrigation strategy based on the water status
