Packaged stem sap-flow measuring device with protective structure

Abstract

The invention provides a packaged stem sap-flow measuring device with protective structure, comprising a package body, tension springs and binding through holes; the package body includes two portionsin tubular symmetric structure; the lateral edges of the rear ends of the two portions of the package body are rotationally connected together through a hinging shaft; two stem sap-flow sensors are mounted at the upper and lower ends of the package body respectively in symmetric manner; a protective cover connected outward is fixedly connected to the outer edge of each of the upper and lower endsof the package body. The packaged stem sap-flow measuring device with protective structure has the advantages that jacket bands and the protective covers are provided, the jacket bands are made withpolyethylene fiber, and therefore, the weight of the whole device can be reduced, and stress upon a stem can be reduced; seven buffer posts in arc shape are connected between the outer edges of the protective covers and the jacket bands, a stress buffer space is formed outside the stem sap-flower sensors, and the stem sap-flow sensors can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, and more specifically relates to a packaged navel orange stalk flow measurement device with a protective structure. Background technique [0002] During the transpiration process of plants, the water absorbed by the root system from the soil is continuously transported to the leaves through the stem flow of the plant, and finally emitted to the atmosphere through the stomata of the leaves. During this process, the liquid in the stem of the plant is always in a state of flow , and the size of plant stem flow can reflect the change of plant transpiration, so the method of measuring plant stem flow can determine the transpiration water consumption of plants. There are many methods to measure plant stem sap flow with marker tracer, the more common ones are isotope tracer method and thermodynamic method. [0003] In the navel orange planting environment requirements, the suitable annual...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the present invention provides a wrapped navel orange stalk flow measurement device with a protective structure. Through structural and functional improvements, the stalk flow meter in the prior art mostly uses a plug-in method to measure stalk flow. , not only damage the navel orange stem, but also easy to fall off during use, and because the navel orange grows faster, the load on the branches is also increasing, and the collision between the branches and the navel orange on the device is inevitable, which may easily cause damage to the exposed stem flow sensor Or fall off, resulting in inaccurate data measurement
