- the apparatus and the like according to the present invention model and use the cultivation strategy of a serious farmer.
- citrus is taken as an example, but the present invention is not limited to citrus and is intended for farm products in general.
- Attribute that determines the quality of citrus at the time of shipment is sugar content, acidity, size, color, etc. of fruit.
- the attribute value of each fruit is measured at the fruit selection field. Points are assigned to the attribute values. Fruits are graded according to the combination of points, and are shipped in boxes in grade units.
- L size fruits are classified into special grade L size, good grade L size, and normal grade L size. Only fruits with a specific range of sugar, acidity and color attribute values are selected for special grades.
- the purchase price of one fruit is determined by whether the fruit is classified as special L size, good quality L size, or average L size, and the total purchase price is the total sales at the time of shipment of a farmer ( Purchase amount).
- the farmer defines the “ideal” when shipping his crops.
- the definition is, for example, “sugar content is 14 degrees” or “size is LL size”. Then, the farmer takes measures to bring the growing fruit closer to its ideal form.
- the farmer has an image of crop growth prediction and takes care of cultivation accordingly.
- senior farmers have time-series changes in their growth based on past cases.
- the change is, for example, that a variety whose sugar content is 13 degrees in December is 12 degrees in November, 11 degrees in October, 10 degrees in September, and so on.
- the farmer feels that it is difficult to reach a sugar content of 13 degrees in December unless the sugar content is 11 degrees in October. Therefore, each farmer checks the past experience every month to see if the fruit is growing smoothly, and if it is too advanced or too late, corrects it.
- Atsushi Farmer compares the performance of his field with other farmers in the same production area.
- the farmer decides whether the performance of his / her field is progressing above the average, lagging or average, and changes the degree of growth promotion.
- the climate of the same production area is similar. If this year is colder than usual, it is likely that the growth rate of the other farms in the area of production is slow, not just those of the farmer. Conversely, in a warm year, any field in the production area will grow faster.
- a farmer's farmland is sunny and usually produces crops that are better than the average of the production area. The farmer will expect crops that are better than usual for the year, regardless of the climate.
- the apparatus of the present invention incorporates this strategic farmer's strategy model, defines the “ideal” in advance, and when “current crop status” is input during cultivation, it is performed at that time Generate and output the measures that should be done.
- the first premise is that in each production area, multiple farmers share information while managing independently. In general, farmers from the same production area are competing with each other, but also working together. The reason is that they ship with the name of the same production area. farmers share the state of crops in each field on a weekly and monthly basis. Alternatively, the agricultural cooperative that organizes the information makes it possible to refer to the state of the crop anonymously. This sharing of information is based on the premise that each farmer measures various attributes (sugar content, acidity, size, etc.) of the crop during the cultivation and can refer to the values mutually.
- FIG. 7 is a diagram of time series data of sugar content and citric acid content (acidity) actually measured in the production area. This data shows past cases. However, the same trend can be expected this year for the same variety in the same production area, so this data can be used as growth prediction data.
- the data as shown in FIG. 7 is often recorded by the prefecture's agricultural extension offices and agricultural cooperatives in each production area. However, the growth forecast map is not uniquely determined from the variety and production area.
- growth prediction diagrams for fruits with a sugar content of 14 degrees at the time of shipment For the same varieties and production areas, multiple growth prediction diagrams for fruits with a sugar content of 14 degrees at the time of shipment, growth prediction diagrams for fruits with a sugar content of 12 degrees at the time of shipment, growth prediction diagrams for fruits with a sugar content of 10 degrees at the time of shipment, etc.
- Each of the two graphs in FIG. 7 includes a plurality of broken lines. Each broken line can be regarded as a different growth prediction chart.
- the third premise is that, when the attribute value of each period is separated from the growth prediction chart, measures to correct it are recorded in advance by cultivation experts.
- the measure is, for example, “The sugar level in October is 11 degrees on the growth prediction chart, but if the current sugar level is 10 degrees, drain (restriction of irrigation)”. Or, the measure is, conversely, “If the current sugar content is 12 degrees, increase irrigation and focus on reducing the size and acidity”.
- each farmer expresses and records the value of the crop varieties and their attributes (referred to as goal values) when they ship at the start of cultivation.
- the goal value is, for example, “shipping with a sugar content of 13 degrees” or “shipping with a size set to LL (12 cm or more)”. Then, the farmer measures and records the attribute value periodically (monthly, weekly, etc.) during the cultivation.
- the device according to the present invention is based on the variety and goal value set by the farmer, with reference to the growth prediction diagram when achieving the goal value, in order to achieve the goal value at a specific time. Find out what attribute values should be taken. Then, the device or the like compares the value of the growth prediction chart with the attribute value of the current period, and if there is any separation, takes out a measure for eliminating the separation and presents it to the farmer (see FIG. 8). ).
- the apparatus of the present invention also includes a function for advising changing the goal value when there is a large difference between the current attribute value and the value of the growth prediction diagram.
- the device according to the present invention presents a measure for eliminating the separation to the farmhouse.
- the measure is registered in advance in the apparatus. As shown in Fig. 9, if you are within ⁇ (standard deviation) in the production area, you can see that you are in the average position of the production area. You can see that there is a situation.
- a measure for eliminating the divergence from the growth forecast map and a measure for eliminating the divergence from the average value or standard deviation of the production area are presented independently, the exact opposite measure may be presented.
- the measure "it is better to irrigate a little" may be shown.
- the sugar content of any farmer's crop may be higher than usual.
- a measure to “drain more water to increase the sugar content” can be presented. In this case, the two measures are the opposite.
- the device according to the present invention does not determine which one should be adopted when contradictory measures are generated. Which measure is to be adopted is determined by a farmer who is a user of the device according to the invention. If the two measures are the opposite, the farmer will think, “This is a situation where different judgments occur, and then we have to think about it properly.” And the farmer will judge carefully with nature.

When selecting a plurality of prediction data, the growth data selection unit 4 searches for a plurality of growth prediction data while gradually relaxing the search conditions. The number of growth prediction data to be selected is given to the cultivation support device 9 as a parameter. This number is usually several, but may be more. FIG. 6 shows an example in which three candidates are selected.
- the cultivation support device 9 stores, in the prediction data ID storage area 10 in the memory, the ID of the growth prediction data most suitable at the present time among the plurality of growth prediction data selected by the growth data selection unit 4.
- the most suitable prediction degree data is a record searched by the growth data selection unit 4 with the smallest degree of loosening while gradually relaxing the conditions.
- the current value storage unit 6 stores a set of records including the measurement value items described in the first embodiment.
- the record stored in the current value storage unit 6 further includes a prediction difference item that is a difference between the attribute value stored in the measurement value item and the estimated value item of the corresponding time of the plurality of growth prediction data. Includes multiple.
- the growth prediction data storage unit 3 since the growth prediction data storage unit 3 stores three growth prediction data, there are also three prediction difference items. This number is not limited to three.
- the prediction difference item is a work area that is required during the process, and the current value storage unit 6 may not be provided.
- the current value storage unit 6 includes a record including a difference accumulation item that stores a cumulative value from the difference at the start of measurement to the latest difference corresponding to each growth prediction data. (Cumulative value record) is also stored.
- the guidance content selection unit 7 is activated when, for example, the farmer periodically inputs the measured value of the crop from the current value collection unit 8 during the cultivation.
- the input measurement value is stored in the current value storage unit 6.
- the instruction content selection unit 7 calculates a difference between this measurement value item and each estimated value of the corresponding time of the plurality of growth prediction data stored in the growth data storage unit 5, and sets the corresponding prediction difference item. Store.
- the instruction content selection unit 7 accumulates the difference calculated for each of the plurality of growth prediction data in the accumulated value record in association with each of the plurality of growth prediction data.
- the guidance content selection unit 7 takes out the growth prediction data having the ID held in the prediction data ID storage area 10 from the growth data storage unit 5.
- the guidance content selection unit 7 further extracts a guidance unit item at the corresponding time in the growth data storage unit 5, extracts guidance content for eliminating the difference value, and outputs the guidance content to the terminal device 11.
- the processing of this part is the same as in the first embodiment. Therefore, in FIG. 6, description of the instruction part item is omitted.
- the guidance content selection unit 4 refers to a plurality of difference accumulation item values in the accumulation value record of the current value storage unit 6, and the growth prediction data indicated by the prediction data ID storage area 10 is most suitable for the measurement value. That is, it is checked whether the difference accumulation item value is the smallest. If the growth prediction data indicated by the prediction data ID storage area 10 is most suitable for the measured value, the process ends without doing anything. If not, the ID of the growth prediction data that is most suitable for the terminal device 11 is terminated. Output.
- the growth data storage unit 5 stores three growth prediction data. They are those of 15, 13, and 11 as prediction IDs.
- the prediction ID 15.
- the instructor of the agricultural cooperative said, “Your goal is a sugar content of 13 degrees, but the current state is behind the planned growth of 13 degrees and is between 11.5 degrees sugar and 10 degrees sugar. May be advised to lower it to 11.5 degrees instead of 13 degrees. If the instructor of the agricultural cooperative still has the means to raise the sugar content rapidly as of October, it may encourage them to do more draining and do their best to increase the sugar content.
- the cultivation support device 9 makes it possible to set an appropriate cultivation target value.
- the reason is that the growth data selection unit 4 stores a plurality of growth prediction data in the growth data storage unit 5 with respect to the designated attribute.
- the instruction content selection unit 7 outputs an identifier of growth prediction data in which the difference between the measured value and the intermediate target value is small.
- FIG. 11 shows the overall configuration of the cultivation support apparatus 92 according to the present embodiment.
- the cultivation support device 92 includes a growth data setting unit 42, a growth data storage unit 4, a guidance content storage unit 2, and a guidance content selection unit 7.
- the growth data setting unit 42 selects or generates a growth table including intermediate target values at a plurality of intermediate time points up to the shipping time determined from the cultivation conditions, including the cultivation region, variety, shipping time, and final target value. And stored in the growth data storage means.
- the instruction content storage unit 2 stores instruction contents according to the difference between the measured value and the intermediate target value for the crop to be cultivated.
- the instruction content selection unit 7 acquires the measured value of the crop to be cultivated at each of the plurality of intermediate time points, compares it with the intermediate target value at the intermediate time point, and determines the instruction content from the instruction content storage unit based on the difference between the two. Select to output.
- the cultivation support device 92 makes it easy to achieve a target value, for example, a target sugar content, at the time of shipment in the cultivation of agricultural products.
- a target value for example, a target sugar content
- the reason is that the growth data setting unit 42 selects or generates growth prediction data that matches a given target condition and stores it in the growth data storage unit 4. This is because the guidance content selection unit 7 determines and outputs the guidance content based on the growth prediction data.
