Year, month and day
2. Collecting day-by-day temperature data corresponding to the dates;
and (4) acquiring meteorological data according to the acquired phenological period information, namely acquiring day-to-day temperature-averaging data of corresponding years. The effective accumulated temperature is calculated according to the following formula:
W d =W r -10
in the formula, daily mean temperature W r When the temperature is higher than 10 ℃, the effective accumulated temperature exists, and calculation can be carried out; day average temperature W r When the temperature is less than 10 ℃, the effective accumulated temperature W is in the day d Is denoted by 0, where W d Effective accumulated temperature in the same day, W r The data are temperature data.

Example 2
In order to better understand the scheme, the embodiment takes a leishan tea garden as an example for description, a main flow is shown in fig. 3, and specific technical contents are as follows:
the data are inquired, the picking start time of the spring tea in the three years of 2019-2021 is 3.12, and the end date is 4.23. Namely:
beginning of spring tea picking The picking of the spring tea is finished
Date 3.12 4.23
Sequence of the day 71 113
The daily average temperature data of three years in 2019, 2020 and 2021 are obtained through GSMaP meteorological satellite data, and the daily effective accumulated temperature is calculated by using a daily effective accumulated temperature calculation formula. And calculating to obtain the effective accumulated temperature sum of the sequences 1-71 and 72-113 in each year in three years.
2019 2020 2021 Average of three years
Sequence 1-71 12.993 62.306 28.033 34.444
72-113 in the sequence 189.47 123.498 164.396 159.1213
Then, the maturity index can be calculated as:
y=x/34.44 (x<34.44)
=1+(x-34.44)/159.12 (34.44<x<193.56)
in the formula, x is the effective accumulated temperature accumulated from the beginning of the sequence 1.
Taking this kind of tea as an example, suppose that the current obtained effective accumulated temperature accumulated value of the current year through the internet of things device is 28.5, and the daily average temperature forecast result of 7 days in the future can be obtained, there are:
days of the future 1 2 3 4 5 6 7
Average daily temperature 12.35 11.16 10.40 9.18 11.19 12.78 10.58
Effective accumulated temperature 2.35 1.16 0.40 0.00 1.19 2.78 0.58
Accumulated temperature accumulation 30.85 32.01 32.41 32.41 33.60 36.38 36.96
Degree of maturity 0.90 0.93 0.94 0.94 0.98 1.01 1.02
The data in the table illustrate that: the daily average temperature is obtained through the Internet of things equipment; the effective accumulated temperature is obtained by calculating the average daily temperature in an effective accumulated temperature calculation formula; the accumulated temperature is obtained by adding the effective accumulated temperature of the day to the accumulated value of the effective accumulated temperature of the year, for example, when the number of days in the future is 1, the accumulated temperature =28.5+2.35=30.85, when the number of days in the future is 2, the accumulated temperature =30.85+1.16=32.01, and so on; the maturity is calculated by substituting the accumulated temperature into a maturity index calculation formula, because the accumulated value of the effective accumulated temperature obtained in the current year is 28.5, the corresponding period of the tea is between the sequence of 1 and 71, the maturity of the current day is calculated by applying the formula in two intervals of 34.444 and 159.1213 according to the accumulated temperature of seven days in the future, and the day when the maturity first reaches 1 is determined as the exploitation period according to a defined threshold interval.
From the maturity count calculations in the table, it can be seen that, in this case, the future day 6 will be the leaf date of the garden in leishan county.
