Corn high temperature risk level calculation method based on temperature data

Abstract

The invention relates to a method for calculating the high temperature risk level of corn based on air temperature data, comprising: collecting and recording the ambient temperature every predetermined time interval; comparing with the preset temperature and recording the difference of the ambient temperature value greater than the preset temperature; The daily high temperature index is obtained by summing the difference between the ambient temperature value of the set temperature and the duration of the ambient temperature value greater than the preset temperature; the daily high temperature index is graded and quantified to obtain the high temperature index grade. The present invention calculates the high temperature duration and the number of high temperature days by hourly temperature data, obtains the high temperature index of the next day, compares the high temperature index classification standard and the high temperature index reclassification standard, obtains the final high temperature index grade of the day, and obtains the daily high temperature index grade through interpolation analysis. The high temperature risk distribution map of month, quarter and year can quickly obtain the distribution of severe high temperature areas, provide support for the avoidance of agricultural disasters, provide evidence for agricultural activities, and improve the efficiency and accuracy of farming.

Description

technical field [0001] The invention relates to the field of agricultural information technology, in particular to a method for calculating high temperature risk levels of corn based on air temperature data. Background technique [0002] This section introduces readers to background technologies that may be related to various aspects of the present invention, and it is believed that useful background information can be provided to readers, thereby helping readers to better understand various aspects of the present invention. Accordingly, it is to be understood that the descriptions in this section are for the purposes stated above and do not constitute admissions of prior art. [0003] With the warming of the global temperature, high temperature in summer often occurs, and the high temperature weather is earlier than in previous years, and the high temperature lasts for a long time, which is prone to extreme weather. Obviously, as well as the difference in soil moisture, th...

Problems solved by technology

[0004] Some stages in the growth period of corn, such as the flowering stage of corn, are sensitive to heat damage. Once subjected to high temperature and heat damage, the growth and development of corn will be seriously affected, and phenomena such as corn empty stalks, bald tips, missing grains, and missing rows will appear, resulting in corn The decline in yield and quality will seriously affect the harvest yield and economic income of farmers, so a simple and efficient high temperature risk assessment method is needed for quick calculation
