Problems solved by technology

Different plants have different ability to absorb nutrient solution, and the amount of transpiration or transpiration rate is also different, and the water lost through transpiration in the process of plant growth still accounts for a large proportion. Water replenishment is of great significance, but now there is a lack of accurate, effective and reasonable transpiration measurement methods and equipment

Embodiment Construction

[0039] The technical solutions of the present application are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0040] In order to measure the transpiration of plants, the in vitro weighing method is traditionally used. Cut part of the branches and leaves of the plant away from the parent body, use the principle of plant transpiration to lose water and reduce weight, and use a load cell to measure the water loss of the branches and leaves in a certain leaf area within a certain period of time, so as to obtain the transpiration rate. However, with the above method, on the one hand, since the branch...

Abstract

The invention discloses a plant irrigation and drainage amount metering system, and the system comprises a workbench which is of a groove-shaped structure and is used for containing a potted plant; the supporting frame is arranged below the workbench; the weight detection module is arranged on the supporting frame, and the weight detection module supports the bottom of the workbench and is used for detecting the weight of the workbench and the weight of substances on the workbench; the liquid discharge pipe is connected with one end of the workbench; and the flow metering device is arranged below the liquid discharging pipe and is used for measuring the liquid discharging amount. According to the plant transpiration amount calculation method and device, real-time measurement and continuous monitoring are carried out, the reliability of the calculated plant transpiration amount is higher, the numerical value is more accurate, and the plant transpiration amount calculation method and device have important guiding significance for reasonable irrigation of plants.

Description

technical field [0001] The present application relates to the technical field of agricultural irrigation, in particular to a plant drainage and irrigation measurement system. Background technique [0002] The premise of agricultural modernization is agricultural informatization. The real-time digital collection, analysis and processing of crop holographic information (growth environment, physiological, biochemical information, etc.) is of great significance for improving the level of agricultural information management and guiding agricultural production. [0003] In the field of crop irrigation, a reasonable amount of irrigation contributes to the biomass accumulation of plants and is crucial to the growth of plants. Different plants have different absorption capacity for nutrient solution, and the amount of transpiration or transpiration rate is also different, and the water lost through transpiration in the process of plant growth still accounts for a large proportion. ...
