Plant watering decision system and method

Abstract

The invention provides a plant irrigation decision-making system and method, comprising: a water potential meter, a power supply device, a liquid flow meter, a data collector and a processing terminal, wherein the water potential meter is fixed on the base end and the top end of the plant to be measured, and a reference The base end and the top of the plant; the liquid flow meter is fixed on the plant to be tested and the reference plant; the water potential and the transpiration water consumption rate collected by the water potential meter and the liquid flow meter pass through the data collector The collected data is forwarded to the processing terminal; the power supply device supplies power to the water potential meter and the liquid flow meter. The system and method provided by the invention realize long-term and accurate monitoring of plant water status without destructive damage to plants.

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
