Description

  The present invention generally relates to a method for managing planted plants. More specifically, the present invention relates to a plant management method using an IC tag.

  It is known that the productivity of crops and trees used for agriculture and forestry varies greatly depending on the variety. Moreover, even if it is the crop of a same kind or a tree, the productivity is influenced by the growth conditions, such as the site conditions and climate where a crop or a tree is planted. Therefore, in order to increase the productivity of crops and trees, the cultivar obtained by selection or transfer is tested for genetic excellence and adaptability to the land actually used, and is suitable for planting land. Work to select crop varieties is required. The verification involves actually planting the plant on the managed land and judging its growth potential.

In particular, when a plant to be planted is a woody plant such as a tree for planting, a test forest called a next generation test forest has been provided so far in order to determine growth potential. However, a large number of next generation certified forests are required according to various location conditions, and the growth of woody plants is extremely slow. The time and effort required for sex testing is tremendous.
Furthermore, as a population used for selection of varieties, several tens to several hundreds of varieties are planted, but as the number of varieties increases, the number of samples required for testing becomes enormous. When testing such a large number of samples, it is particularly necessary to accurately and reliably track the sample and manage the relevant information.

  For many plants of the same variety, for example, select a large number of excellent trees with excellent growth, etc., and when taking out a large number of cuttings and seedlings with each excellent tree as the mother tree, plant the seedlings randomly. Therefore, in order to investigate the relationship between the growth data and the parent tree line, it is necessary to identify the parent clone of the individual.

Usually, identification of varieties and strains is done by attaching tags such as tags and bar codes with individual information such as varieties, etc. to planting points or plants. There is a problem that information or tags themselves are easily lost.
In recent years, it has been reported that the use of DNA markers is effective as a method for discriminating plant varieties / lines (see Patent Documents 1 and 2). In this method, DNA is extracted from the planted plant and the individual is identified from the difference in the base sequence. However, in the identification system using DNA, it takes time, labor, and cost for identification, and there is a problem that the amount of information necessary for judging a good tree cannot be accumulated sufficiently, and the identification ability of the system is guaranteed 100%. The problem is that the reproducibility of the test is not perfect.
Japanese Patent Laid-Open No. 2003-079375 JP 2002-291475 A JP 2002-319006 A Japanese National Patent Publication No. 11-513518 JP 2002-169952 A

  An object of the present invention is to provide a plant management method that identifies plant varieties / lines that cannot be determined by appearance, records information such as growth potential of planted plants easily and without error, and can determine land adaptability, etc. It is.

In order to solve the above problems, the present invention employs the following configurations (1) to (10).

(6) The plant management method according to (2), wherein the individual identification is performed to identify the variety.
(7) The plant management method according to any one of claims 1 to 6, wherein the individual identification number is recorded on the IC tag in a read-only and non-rewritable state.
(8) The plant management method according to (7), wherein management is performed by storing the individual identification number, individual information corresponding to the individual, and growth information in an information storage memory area of the computer main body.
(9) The plant management method according to (8), wherein the individual information is a plant variety or genotype.
(10) An IC tag reading function is added to a portable terminal having a wireless communication function, an individual identification number is read from a plant individual, and information on the result of observation of the plant individual is input to the portable terminal, and the wireless communication function The plant management method according to (8) or (9), which is transmitted to a computer main body.

  According to the present invention, it is possible to manage and analyze a huge number of plant growth information and the like with a computer at a plantation site or a head garden. Measurement and recording of the growth state can be performed with little effort, and the possibility of erroneous data entry is greatly reduced.

  When the information to be identified is a variety, it is possible to accurately identify the variety that has been randomly planted in a large number of planting areas without requiring advanced techniques and knowledge locally. By associating the identified cultivar information with the growth potential at the planting site, it is possible to obtain detailed information on the interaction between various location conditions and varieties, and to determine the excellent varieties. High productivity can be secured by selecting excellent varieties and planting them on farmland, forest land, and the like. In addition, for the selected excellent varieties, the location factors of the planting land and the growth data are correlated to clarify the influence of the location factors on the growth of the superior varieties, thereby planting the excellent varieties on new land. You can make growth predictions when you do.

Hereinafter, the present invention will be described in detail.
In the present invention, the IC tag attached to the plant body may be any known IC tag, either a contact IC tag or a non-contact IC tag such as a radio frequency identification (RFID). But you can use it. In the case of application to afforestation, it is assumed that an IC tag exists on a tall tree, so a non-contact method is preferable.
Examples of the shape of the IC tag include a microchip, a card type, a button type, a stamp size, and the like, but are not limited thereto.
There are an electromagnetic induction method and an electrostatic coupling method as a method for generating an electromotive force at the time of data exchange, and any of them can be used in the present invention.
The electrostatic coupling method is developed by Motorola, and the technique disclosed in Patent Document 4 can be used. In this method, the distance of radio waves can be increased by expanding the extension antenna.

In order to transmit information from the IC tag, there are a passive method in which an electromotive force is generated by an external radio wave and an active method in which the IC tag has a power source. In the active method, it is possible to use radio waves in the 300MHz band without a license, measure the distance between the IC tag and the receiver, and allow radio waves to travel over 30m. Is possible.

Hereinafter, the electromagnetic induction type that is most often used and communicates by passive radio will be described.
The radio frequency used for IC tag communication is not particularly limited, and any of short wave (13.56 MHz), medium wave (below 135 KHz), UHF (860 960 MHz), microwave (2.45 GHz), etc. can be used. . Among them, when the height of the tree is large, UHF or microwave having a long flight distance is preferable, and microwave is particularly preferable from the viewpoint of miniaturization of the tag.
As the tag or the chip of the material, those commercially available from Infineon of Germany, Magellan Technology of Australia, Matrix of America, NEC Electronics of Japan, etc. can be used. Since all of the above are about 1 cm to 5 cm in size, a smaller tag is required for use in embedding in a tree or attaching to a very small seedling.
In recent years, IC chips of 0.5mm square or 0.4mm square, such as Muchip (trademark: Hitachi, Ltd.) and MM chip (trademark: FCC Co., Ltd.), are also available. There is no problem even if it is attached to.
In addition, the above-mentioned electrostatic coupling IC chip (Bistatixs: registered trademark) of Motorola is also very light and small, and can be attached to a small seedling.

  The plant to which the IC tag is attached is not particularly limited, but for example, herbaceous monocotyledonous plants include rice, barley, wheat, rye, onion, corn, sorghum, etc., and herbaceous dicotyledonous plants include soybean, Legumes such as peas, green beans, alfalfa, solanaceous plants such as tobacco, tomatoes and potatoes, cruciferous plants such as rapeseed, cabbage and mustard, cucurbits such as melon, cucumber and pumpkin, celery such as carrots and celery Family plants, Arabidopsis thaliana, etc., and woody plants include eucalyptus, acacia, poplar, pine, cedar, cypress, beech and the like.

  Examples of the method of attaching the IC tag include a method of adhering to the surface of the plant with an adhesive, a method of binding a string attached with the IC tag to the plant, a method of embedding in the plant, and the like. As the string to which the IC tag is attached, a string in which the IC tag is sandwiched between two thin plastic tapes is preferable from the viewpoint of protecting the IC tag.

  It is desirable to assign an individual identification number corresponding to one number to one plant individual to the IC tag. The IC tag may be in a state where only the individual identification number is recorded. It is preferable that the information of the individual identification number is in an unrewritable state. An IC tag that can be rewritten by radio waves is not convenient, but there is a risk that information may change due to unintended radio waves over a long period of time, and it is particularly inconvenient that the individual identification number changes. is there.

  In the plant management method of the present invention, a reader device and a computer main body for reading information recorded on the IC tag are required. The reader device is preferably of a portable type, but can be used even if it is not of a portable type when used in a spike or garden.

  When walking in a plantation and observing the growth of trees and recording the information on the computer itself, a portable terminal (for example, a mobile phone) having a wireless communication function is equipped with an IC tag reading function, and the individual plant to individual It is preferable that the identification number is read and information on the result of observation of the plant individual is input to the portable terminal and transmitted to the computer main body by a wireless communication function (see Patent Document 5). By doing so, there is no mistake in entering information, and the trouble of transferring information can be saved.

  The computer main body has a memory area for storing information. In this area, an individual identification number corresponding to one plant body, individual information, and other information are recognized and stored as one record and are managed. The above information is stored for all plants. Other information other than the growth information is also stored in the same manner.

Here, the individual information is information unique to the plant individual, and is information that has not changed since planting. Examples include varieties, lines (parent trees), genes, base sequences, and the like. Moreover, the management history, such as fertilization before planting, damage history, such as disease and insect damage, etc. are also mentioned.
Typical information of other information is growth information such as weight, volume, tree height, volume, fruit or grain yield.
Other information other than growth information is environment-related information other than individual-specific information, such as planting location information required by GPS (Global Positioning System), precipitation, rainy season, topography, slope, soil Examples include, but are not limited to, physical properties (soil properties, soil color, particle size distribution, presence of bedrock, etc.), soil chemistry (pH, electrical conductivity, organic matter content and composition, inorganic matter content, inorganic ion content, etc.) Is not to be done.
Individual information or other information may be stored only in the computer main body, but a part thereof may also be stored in the IC tag. Since it is stored in the IC tag, it can be referred to locally, which is convenient.

  When recording the individual identification information on the IC tag in a non-rewritable form, it is affixed to paper or plastic tape at regular intervals or supplied to the writer device in a wound state It is preferable. Alternatively, a so-called electronic component carrier tape, which is a paper or plastic tape in which IC chips are inserted at regular intervals, the IC chips are accommodated therein, and then covered with tape.

The writer is controlled by a computer and preferably stores individual identification information and corresponding individual information as a table in advance, and records the individual identification number and individual information on the IC tag accordingly. It is preferable to print an individual identification number at the position by an ink jet method or attach an adhesive label. Since the individual identification number is displayed, there is no need to read and confirm the contents of the IC tag when attaching to the plant body.
As another method, in the case of a tag having an ID region for individually identifying an IC tag and a recorded ID symbol when the IC tag is manufactured, the ID symbol can be used as an individual identification number of the present invention. In that case, it is convenient for various collation operations by separately assigning individual numbers starting from 1, and making the correspondence between the ID symbol and the individual number on the computer main body.

When the tape holding the IC tag is used as it is by adhering or tying it to the plant as it is, it is convenient to use the recording work that is protected by sandwiching the IC tag between two plastic tapes. is there. Further, by printing on a plastic tape with conductive ink, an extended antenna can be formed and the distance of radio waves can be increased.
For example, a metal plate serving as a tree height measuring marker or a radio wave transmitter for measuring tree height may be attached to the plastic tape.
Further, when taking out IC tags one by one and embedding them in a plant body, it is convenient to transport and use in the form stored in the electronic component carrier tape.

  EXAMPLES Hereinafter, although an Example demonstrates this invention further in detail, this invention is not limited to these Examples.

<Example 1>
Selection among growth factors among the interspecific hybrids of the woody plants Acacia mangium and Acacia auriculiformis A. Conn. Ex Benth. For the 20 cultivars, the cultivar name, clone cultivar number, selection data, growth data, and material data for identifying the cultivar were recorded on a computer and used as data for verification using an IC tag as a key.
From each mother tree, cut out branches that have been newly grown and hardened since the spring of that year, remove the lower leaves, and leave 5 to 15 cm long ears, leaving only two leaves at the tips. 150 were prepared.
About half of the tips of the two leaves included in the cuttings were excised, and the base of the cuttings was cut back with a knife. A total of 3000 cuttings were inserted into vermiculite previously packed in a plug tray and moistened.
The plug tray was placed on a bench in a room with controlled temperature (23-25 ° C.) and illuminance (15,000 lux), and the entire plug tray was covered with an acrylic container to maintain high humidity. Irrigation was performed once every two days with a 15-minute water supply. 100 seedlings rooted and growing without problems at the time when 7 weeks passed after insertion were selected for each mother tree and used as a plantation sample.
A string attached with an IC tag on which the species-specific information was recorded was tied to the total of 2000 plantation samples. Five plantations were set, and in each plantation, 20 clones of 20 varieties were planted in total, with a total of 400 clone seedlings planted in a mixed state. The following IC tags were used.
At least for each cultivar to be verified in the same plantation by reading the variety information with the IC tag reader from the attached IC tag 4 years after planting in the plantation planted with the Acacia hybrid tree with the IC tag attached Identify 10 planted trees.

  At this time, the planting position of the Acacia hybrid tree is measured by GPS, and it is confirmed from the location environment information acquired in advance that there is no significant difference in location environment between the planting points of the planted tree. The effects of environmental factors on the location were reduced by excluding planted trees with differences from the survey targets. The tree height of the planted trees of each identified variety is measured with a tree height meter. For the same plantation, the average value of the tree height for each variety is calculated from the measured tree height data, thereby identifying an Acacia hybrid tree variety suitable for the plantation. In addition, the average height of planted trees identified for each variety was analyzed with data and statistical analysis of precipitation, topographic slope, soil properties, nitrogen and phosphorus content in the soil, and statistical analysis. To clarify these effects on the growth of tree varieties.

<Creation of IC tag>
Infineon's inlay (with an antenna circuit made of aluminum on a PET base material and connected to Infineon's SRF55V02P type IC chip) was sandwiched from the front and back with a thin polyester sheet and bonded with adhesive Uses RFID tags.
Reader / writer device: The reader / writer module antenna unit TR3-A301 manufactured by Takaya Co., Ltd., an outer shape of about 50 mm × 15 mm, and a thickness of 10 mm were combined with the controller unit TR3-C201 manufactured by the same company.

<Example 2>
Ten individual trees (elite trees) with relatively high growth potential were selected from Eucalyptus grandis . These 10 trees were used as mother trees, and mother tree numbers from 1 to 10 were assigned.
From each mother tree, cut out new branches that have grown and hardened since the spring of that year, remove the lower leaves, and leave only 2 to 10 cm long cuttings leaving only the pair of leaves at the tip of each tree. Twenty were prepared.
About half of the tips of the two leaves included in the cuttings were excised, and the base of the cuttings was cut back with a knife. At the base of the cutting head, the concentration of sucrose is 2% and the concentration of benomyl [methyl-1- (butylcarbamoyl) -2-benzimidazole carbamate] wettable powder (trade name: Benlate, DuPont) is 500 times. It was immersed in an aqueous solution for 24 hours. A total of 200 cuttings were inserted into vermiculite previously packed in a plug tray and moistened.
The plug tray was placed on a bench in a room with controlled temperature (23-25 ° C.) and illuminance (15,000 lux), and the entire plug tray was covered with an acrylic container to maintain high humidity. Irrigation was performed once every two days with a 15-minute water supply. Ten seedlings rooted at 7 weeks after insertion and growing without problems were selected for each mother tree and used as a plantation sample.

On the computer itself, 100 records were created with the seedling individual number, mother tree number, plantation, and seedling height as fields. In the individual number column, individual numbers from 1 to 100 are entered as serial numbers, and in the mother tree number column, data of mother tree numbers 1 to 10 are arranged for each 10 records. There were two plantations, and five seedlings from each mother tree were assigned to each plantation, and data for plantations A and B were input.
Next, a plastic tape (IC tag tape) having a width of 2 cm and a length of 10 cm prepared by the following method was bonded to each seedling with a thread.
In this way, we planted 50 trees in both AB plantations, and measured the height of the tree, the thickness of the trunk, etc. while taking a portable reader / writer, and recorded it on an IC tag. It can be managed by transferring it to the computer.

<Creation of IC tag tape>
As the IC tag, NETLABEL (trademark: NEC Electronics, EEPROM 1024 bits) was used, and the ID symbol (non-rewritable ROM data) stored in the individual ID area of the IC tag itself was adopted as the individual identification number. A high-density polyethylene film with a total thickness of 25 μm having a 5 μm-thick ethylene / vinyl acetate copolymer layer as a heat-seal layer is cut into 2 cm wide and 10 cm long to form a strip, and the IC chip is placed in the center of the heat seal layer side. Then, the same strip was placed so that the heat seal layers face each other, and the portions other than the portion of the IC tag were sealed with ironing, and 100 IC tag tapes were produced.
Each IC tag tape was read with a reader / writer (manufactured by NEC Electronics, using 2.45 GHz microwave, reading distance of about 1.3 m), and the ID symbol was recorded on a record of the computer main body. The individual number of the computer main body corresponding to it was recorded on the IC tag. Further, an adhesive label on which numbers 1 to 100 were printed one by one was attached to the IC tag tape so as to match the individual number.
