[0028] Step 1: Investigate the data of jasmine's stable flowering period for many years;

[0029] The survey of the stable flowering period of at least 1,000 mu of jasmine in the same area for more than 10 consecutive years obtained through model user monitoring or other means;

[0030] Step 2: Prepare meteorological data;

[0031] Meteorological data use the daily meteorological data released free of charge by the nearest national weather station. Generally, there are national weather stations or county-level weather stations within 100 kilometers. Historical weather data can be traced back decades; meteorological data indicators include: Daily maximum temperature, average temperature, minimum temperature, average relative humidity, minimum relative humidity, precipitation, sunshine hours.

[0032] Step 3: Determine the suitable meteorological conditions for flowering of jasmine;

Abstract

The invention discloses a construction method of a jasmine flower yield regional forecasting model based on meteorological conditions. The construction method comprises the following steps: step 1, investigating data of stable flowering periods of jasmine flowers for many years; step 2, preparing meteorological data; step 3, determining meteorological conditions suitable for flowering of the jasmine flowers. In step 1, the stable flowering period survey of at least more than 1000 mu of jasmine flowers in the same area for more than 10 years is obtained through monitoring of a model user or other modes. The regional meteorological condition discrimination model for jasmine flower suitable for blooming is simple and practical, parameters are easy to obtain, the prediction precision is high, the jasmine flower suitable blooming period is discriminated based on day-by-day meteorological conditions, field planting technology regulation and control and market price expectation are predicted in advance. On the basis of the temperature parameters of the jasmine flower suitable for the flowering period, field facilities are set to regulate and control field micrometeorological conditions and water and fertilizer management measures, and the optimal micrometeorological conditions are created for high yield.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for constructing a regional forecast model of jasmine flower yield based on meteorological conditions. Background technique [0002] The output of jasmine in Hengzhou City, Guangxi Zhuang Autonomous Region accounts for 60% of the world and 80% of domestic production. At present, the cultivation technology is very mature, but there is a lack of quantitative research work to determine the regional meteorological conditions suitable for flowering of jasmine through data mining methods, especially in the case of unfavorable conditions. The weather conditions will seriously affect the formation of production. This patent analyzes the regional meteorological conditions suitable for flowering of jasmine, directly provides a scientific basis for the regulation of micro-meteorological conditions in the field and water and fertilizer management, and also provides a refere...
