Definitions
- the present invention relates to a farm work support method and a farm work support apparatus.
- Crop crops are planted according to the customary cultivation calendar suitable for each harvest season.
- the farmer makes a plurality of planting plans assuming the target harvest time and performs actual cultivation. For example, in order to shift the harvest time, the cultivation start time is shifted to a plurality of times, and the cultivation is performed.
- an object is to calculate a cultivation start time that can suppress a deviation from the plan with respect to an interval between harvest times of a plurality of cultivations.
- the computer executes a process of determining today as the start date of the second cultivation.
- cabbage of variety M is adopted as a specific example of the agricultural product.
- the cabbage of variety M is hereinafter referred to as “cabbage M”.
- FIG. 1 is a diagram showing an example of a cultivation plan for cabbage M in the embodiment of the present invention.
- the cultivation plan A shown in FIG. 1 regarding the cabbage M, three cultivations of cultivation 1 to cultivation 3 whose planting dates are different from each other are planned.
- “cultivation” refers to a unit of work in which various operations are performed in common during a period from the start of preparation for cultivation to the harvest of the crop regarding the same type of crop.
- the fixed planting date is represented by a white circle
- the harvest date is represented by a black circle.
- FIG. 1 shows the contents of the cultivation plan A when the cultivation plan A is planned.
- the fixed planting date for cultivation 1 is March 1st.
- the interval between the harvest date of cultivation 1 and the harvest date of cultivation 2 is 7 days.
- the interval between the harvest date of cultivation 1 and the harvest date of cultivation 3 is 14 days.
- the interval between the harvest date of one cultivation and the harvest date of another cultivation is hereinafter referred to as “harvest interval”.
- the predicted harvest date is a predicted value of the harvest date.
- the predicted harvest date for each cultivation is calculated using the effective integrated temperature, which is an example of weather conditions.
- the effective integrated temperature is the integrated value of the temperature that contributes to the growth of each day.
- the effective integrated temperature is the integrated value of the temperature that contributes to the growth of each day.
- the average daily temperature exceeds 5 ° C.
- 12 ⁇ 5 7 ° C.
- Average temperatures below 5 ° C are not added to the effective integrated temperature.
- “° C./day” is a unit of effective integrated temperature at the daily average temperature.
- the average temperature of each day until the effective accumulated temperature is reached is unknown. Therefore, a predicted value is used for the average temperature of each future day.

This is because the period according to the cultivation plan A is a period in which the rate of increase in effective integrated temperature increases daily. That is, this is because the number of days required to obtain the same effective integrated temperature is a period in which the number of days decreases in each day.
- the planting date can be determined by determining the harvest date.
- the weather conditions are not the same every year, and the planted plants grow by experiencing the temperature of the year.
