Construction method of citrus yield area forecasting model based on meteorological condition

Abstract

The invention discloses a construction method of a citrus yield area forecasting model based on meteorological conditions. The construction method comprises the following steps: 1, preparing citrus yield data; 2, preparing meteorological data; and 3, determining a citrus yield area forecasting model. In the step 1, monitoring data of at least 1000 mu of oranges in the same area for more than 10 years is obtained by a model user through monitoring or other modes. The citrus yield area forecasting model based on the meteorological conditions is simple and practical, parameters are easy to obtain, and forecasting precision is high; the regional citrus yield can be forecasted in real time, and field planting technology regulation and market price expectation are forecasted in advance; on the basis of citrus yield area forecasting model parameters, field facilities can be set to regulate and control field micrometeorological conditions and carry out real-time water and fertilizer management, and optimal management conditions are created for high yield.

Description

Technical field [0001] The present invention relates to the field of crop cultivation techniques, and in particular, a construction method of a quarter-based regional prediction model of meteorological conditions. Background technique [0002] Citrus is the largest fruit tree in Guangxi. Current cultivation techniques have matured, but citrus production is affected by meteorological conditions. The output fluctuations between different years are around 30%, forming size. However, there is currently no quantitative prediction model to achieve evaluation of citrus production. This patent is based on early forecast production in advance, providing scientific basis for the regulation of field water fertilizer management and micro - gas conditions. [0003] Any condition or a combination of several conditions in the existing cultivation techniques cannot achieve a region, a plot, a tree of citrus production, including land conditions, tree, water fertilizer management, production (spa...
