Problems solved by technology

[0003] However, the existing technology has the following technical problems: the real-time performance is poor, the forecast data of the topic is issued according to a certain frequency, but the weather changes very fast, and there will be problems due to the lack of timely update of the weather data before the current topic and the next topic The resulting judgment is inaccurate; more suitable harvest time suggestions cannot be given based on different varieties. Variety is one of the important factors in determining the harvest time. Different varieties take different times to mature, so the harvest time is also different.

Embodiment 1

[0082] see figure 1 , a schematic diagram of a crop harvest time prediction method provided in the embodiment of the present application, as shown in figure 1 As shown, the method includes steps S101 to S106:

[0083] S101. Determine the first accumulated temperature value from the historical database;

[0084] S102. Determine the second accumulated temperature value according to the weather forecast data for W days in the future;

[0085] S103. Determine a first maturity date according to the first accumulated temperature value and the second accumulated temperature value;

[0086] S104, calculating the grain moisture value of the crop;

[0087] S105. Determine the second maturity date according to the moisture value of the grain;

[0088] S106. Determine the harvest time of the crop according to the weather forecast data and the second maturity date.

[0089] Wherein, W is a positive integer greater than or equal to 1. As a preferred example, W is 15 or 40, that is, th...

Abstract

The invention discloses a crop harvest time prediction method and device and a storage medium, which are used for predicting the crop harvest time, reducing the harvest cost and improving the harvest quality. The crop harvest time prediction method disclosed by the invention comprises the following steps: determining a first accumulated temperature value from a historical database; determining a second accumulated temperature value according to weather forecast data of the future W days; determining a first mature date according to the first accumulated temperature value and the second accumulated temperature value; calculating a grain moisture value of the crop; determining a second ripening date according to the grain moisture value; determining the harvesting time of the crop according to the weather forecast data and the second mature date; wherein W is a positive integer greater than or equal to 1. The invention further provides a crop harvest time prediction device and a storage medium.

Description

technical field [0001] The present application relates to the field of agriculture, in particular to a method, device and storage medium for predicting crop harvest time. Background technique [0002] In the field of agricultural production, predicting the best harvest time of crops is the guarantee of high yield and good harvest, and it is of great significance to improve the quality of crops. In the existing technology, the local meteorological bureau will give thematic weather forecasts of rainfall, frost, sunny weather and other weather processes based on the maturity period of crops with large local planting areas every year. Judge the appropriate harvest time, and then the surrounding growers follow suit. [0003] However, the existing technology has the following technical problems: the real-time performance is poor, the forecast data of the topic is issued according to a certain frequency, but the weather changes very fast, and there will be problems due to the lack...
