発明の名称 (英語) VASCULAR SAP MEASUREMENT SENSOR AND PRODUCTION METHOD FOR VASCULAR SAP MEASUREMENT SENSOR
発明の概要(英語) The present invention provides a vascular sap measurement sensor in which a flow channel into which vascular sap flows is less susceptible to becoming blocked with plant tissue. This vascular sap measurement sensor (1) is provided with a collection probe (20) for collecting vascular sap, and a support part (10) for supporting the collection probe (20). The collection probe (20) has formed therein a collection flow channel (21) into which vascular sap flows, and an entrance opening (24) to the collection flow channel (21) is formed in a lateral surface of the collection probe (20). Due to this configuration, when the collection probe (20) is used to pierce a plant, the collection flow channel (21) is unlikely to become blocked with plant tissue.
従来技術、競合技術の概要(英語) BACKGROUND ART
The production of crops and plants and the like, from the viewpoint of productivity growth of the plants at an appropriate timing in accordance with the state required to perform supply irrigation or nutrients. Therefore, without affecting the growth of the plants, the growth condition can be accurately grasped becomes very important.
In general, many agricultural site, such as the non-rainfall days based on the experience and intuition to grasp the state of growth of the plants in the situation. However, growth of the plants by a method based on experience and manage the situation, such time and labor and requires skill. In addition, a reference index based on personal experience or the like. Therefore, the growth of the plants on the basis of experience as a method to grasp the state, it is difficult to conveniently carried out by anyone.
On the other hand, in recent years, plant crops and trees based on the biometric information for fertilization and moisture control of the variety of techniques have been developed. Granier in the measurement method using the method has attracted attention. In addition, a method of measuring the flow rate of the pulse signal causes a method has also been known (for example, Patent Document 1).
Is Patent Document 1, the master tree is formed by a drill or the like can be placed in the holes 3 of the rod 1 of the rod-like temperature sensor and a heater has been disclosed an apparatus. Then, in the Patent Document 1, a temperature sensor and a rod-shaped heater of the device formed in the side members of the tree and placed in the hole, after the lapse of a predetermined period of time based on the temperature difference between the two sensors in a tree which causes a flowing through the flow rate of the disclosed technology.
However, the apparatus of Patent Document 1, in the first place which causes a relatively large diameter stems in the tree in order to measure the flow rate of the flows have been developed and, used in the apparatus having a rod-shaped sensor of certain magnitude. Therefore, the apparatus of Patent Document 1, a small number of stalk diameter mm cannot be applied to the plant.
To grasp the state of growth of plants, plant directly measure the vascular flow rate of liquid is important. In particular, such as crops and plants to improve the productivity and quality is, the new plant fruit sugar terminal or the like, such as crops and plants located in the vicinity of the plant on the order of a few mm thickness in the vascular detail is possible to measure the kinetics of the liquid is very important.
Therefore, the present inventors, new sugar fruit or plant of the terminal such as the kinetics of the liquid flowing in the details of the vascular bundle can be measured (the dynamic water) water plant dynamic sensor (Patent Document 2) are contemplated. Patent Document 2 is, like sugar fruit and the new terminal can be formed to pierce the various sensor probes of the disclosed dynamic water plant. Probe is stuck into the details of the plant are arranged, by making use of water dynamics granier can be measured.
In addition, in Patent Document 2, the motion sensor of the plant into a vascular plant water will flow into the flow path is formed in a the collection probe is disclosed.
