Is accepted as the spraying amount R5.

The spray reception unit 35 associates the reception spray amount Pi for each section Qn with the divided data D2n corresponding to the section Qn of the second field map M2 (reception spray amount Pi for each section Qn = divided data D2n). That is, the reception spray amount Pi received by the spray reception unit 35 is associated with the division data D2n for each section Qn and the position information, and the division data D2n for each section Qn is an index of the reception spray amount Pi.

The display control unit 32 causes the second map display unit 52 to display the reception spray amount Pi for each section Qn received by the spray reception unit 35 as the second field map M2 corresponding to the position of the field. That is, the display control unit 32 causes the display unit 25 to display the setting screen T1 and displays on the screen the relationship between the reception spray amount Pi, which is the spray amount received by the spray reception unit 35, and the section Qn. The second field map M2 divides the division data D2n corresponding to the division Qn set by the spray reception unit 35 into preset groups, and information (numbers, characters) indicating the group of the division data D2n for each division Qn. , Color, etc.) is displayed on the setting screen T1.

In this embodiment, regarding the display of the divided data D2n, the divided data D2n is divided into a plurality of groups, and the information indicating the groups is displayed on the setting screen T1 to indicate the size of the reception spray amount Pi. Although the divided data D2n is displayed for each section Qn as an index, the value of the divided data D2n (reception spray amount Pi for each section Qn) itself may be displayed on the setting screen T1.

The spraying determination unit 37 determines whether or not the reception spray amount Pi, which is the spray amount received by the spray reception unit 35, is appropriate. As described above, the mesh setting unit 34 assigns data (field data) of any one of crop yield, taste, lodging degree, soil composition, soil depth, and tillage depth to the plot Qn in the field and disperses it. The reception unit 35 receives the spray amount for each section Qn, and the spray judgment unit 37 determines the relationship between the reception spray amount Pi and any of the yield, taste, lodging degree, soil composition, soil depth, and tillage depth of the crop. Based on this, it is determined whether or not the reception spray amount Pi is appropriate. In the following description, the section Qn that the spraying determination unit 37 determines that the reception spray amount Pi is appropriate is described as the first section Qa, and the section that the spray determination unit 37 determines that the reception spray amount Pi is not appropriate. Qn will be described as the second section Qb.

The spraying determination unit 37 determines whether or not the reception spraying amount Pi is appropriate based on a predetermined standard. In the present embodiment, the storage unit 30 stores a table T3 showing the relationship between the variety of the crop and the standard fertilizer application amount (standard application amount αm) corresponding to the variety, and the application determination unit 37 stores the table T3. The validity of the reception spray amount Pi is judged based on.
As shown in FIG. 5, the table T3 shows the relationship between the varieties of crops and the reference spray amount αm corresponding to the varieties. Specifically, the spraying determination unit 37 acquires the reference spraying amount αm from the table T3 of the storage unit 30 according to the variety of the crop in the field and the threshold value on the upper limit side from the standard spraying amount αm (first threshold value). βm) and the threshold value on the lower limit side (second threshold value γm) are calculated. The spraying determination unit 37 calculates the first threshold value βm and the second threshold value γm from the reference spraying amount αm based on a predetermined calculation formula. The spraying determination unit 37 calculates the first threshold value βm by multiplying the reference spraying amount αm by a preset value (first set value X1) (βm = αm × X1).

On the other hand, the spraying determination unit 37 calculates the second threshold value γm by multiplying the reference spraying amount αm by a preset value (second set value X2) (γm = αm × X2). The first set value X1 and the second set value X2 are values set via the management computer 1a and the like and stored in the server 1b. For example, the first set value X1 is 150% and the second set value X2 is 50%. That is, when the reference spray amount αm is 40 kg / 10a, the first threshold value βm is calculated to be 60 kg / 10a, and the second threshold value γm is calculated to be 20 kg / 10a.

Explaining the table T3 shown in FIG. 5 as an example, when the cultivar of the crop is "Hitomebore", the spraying determination unit 37 acquires the standard spraying amount α1 corresponding to the cultivar "Hitomebore" from the table T3. The spraying determination unit 37 multiplies the reference spray amount α1 by the first set value X1, calculates the threshold value on the upper limit side (first threshold value β1) (β1 = α1 × X1), and sets the reference spray amount α1 as the second set value. Multiply X2 to calculate the lower threshold (second threshold γ1) (γ1 = α1 × X1). When the cultivar of the crop is "Akitakomachi", the spraying determination unit 37 acquires the standard spraying amount α2 corresponding to the cultivar "Akitakomachi" from the table T3. The spraying determination unit 37 multiplies the reference spraying amount α2 by the first set value X1, calculates the threshold value on the upper limit side (first threshold value β2) (β2 = α2 × X1), and sets the reference spraying amount α2 as the second set value. Multiply X2 to calculate the lower threshold (second threshold γ2) (γ1 = α2 × X2).

The first set value X1 and the second set value X2 can be arbitrarily changed by operating the management computer 1a, and are not limited to the above-mentioned values. The first threshold value βm and the second threshold value γm are not configured to be calculated based on the reference spray amount αm as described above, but can be set by inputting arbitrary values by operating the management computer 1a. It may be configured. The storage unit 30 stores the model number of the spraying machine 2 and the maximum amount of the spraying amount of the spraying machine 2 in association with each other, and the spraying determination unit 37 sets the maximum amount of the spraying amount as the first threshold value based on the model number. It may be configured to be acquired as βm. Further, the storage unit 30 stores the model number of the spraying machine 2 in association with the minimum amount of the spraying amount of the spraying machine 2, and the spraying determination unit 37 stores the minimum amount of the spraying amount based on the model number. It may be configured to be acquired as two threshold values γm.

Further, when the reception spraying amount Pi is equal to or less than the first threshold value βm and equal to or more than the second threshold value γm (γm ≦ Pi ≦ βm), the spraying determination unit 37 determines that the reception spraying amount Pi is appropriate and sprays the reception. When the amount Pi exceeds the first threshold value βm or is less than the second threshold value γm (βm <Pi, Pi <γm), it is determined that the reception spray amount Pi is not appropriate.
The spraying determination unit 37 only needs to be able to determine the validity of the reception spray amount Pi, and the determination criteria are not limited to the above configuration. In the spray determination unit 37, the reception spray amount Pi is less than the first threshold value βm and the first is When the 2 threshold value γm is exceeded (γm <Pi <βm), it is determined that the reception spray amount Pi is appropriate, and the reception spray amount Pi is 1st threshold value βm or more or 2nd threshold value γm or less ( (Βm ≦ Pi, Pi ≦ γm), and the reception spray amount Pi may be judged to be inappropriate. Further, when the reception spraying amount Pi is equal to or less than the first threshold value βm (Pi ≦ βm), the spraying determination unit 37 determines that the reception spraying amount Pi is appropriate, and the reception spraying amount Pi sets the first threshold value βm. If it exceeds (βm <Pi), it may be determined that the reception spray amount Pi is not appropriate, and the validity of the reception spray amount Pi is determined based on one of the first threshold value βm and the second threshold value γm. It may have such a configuration.

The spray amount Pi can be modified. When the spraying determination unit 37 determines that the modified reception spray amount Pi is appropriate, the display control unit 32 hides the warning display unit 60.
In addition, the warning display unit 60 may show a warning by differentiating the display form of the second section Qb from the first section Qa among the plurality of sections Qn, and the display form is not limited to the above-mentioned form. For example, the warning display unit 60 is a display image in which the spraying determination unit 37 grays out the second section Qb, or a display image in which the outer periphery of the section Qn in which the reception spray amount Pi exceeds the first threshold value βm is bordered in red. It may be a display image or the like that borders the outer periphery of the section Qn in which the reception spray amount Pi is less than the second threshold value γm in blue.

Further, when it is determined that the reception spray amount Pi is not appropriate, the display control unit 32 may change the display form of the spray input unit 54c in addition to or instead of the warning display unit 60 to indicate a warning. .. In such a case, the display control unit 32 displays the input unit corresponding to the reception spray amount Pi, which is determined to be inappropriate, in a different display form from the first to fifth input units. For example, the display control unit 32 displays the background color of the input unit corresponding to the reception spray amount Pi determined to be appropriate in white, and the background color of the input unit corresponding to the reception spray amount Pi determined to be appropriate. Is displayed in red.

That is, as shown in FIG. 6, in the display control unit 32, the reception spray amount P5 corresponding to the fifth group G5 exceeds the first threshold value βm, and the reception spray amount P1 corresponding to the first group G1 is the second.
