Paddy rice blast and leaf blast condition forecast information collection device and forecast method

Abstract

The invention discloses a rice blast and leaf blast condition forecast information collecting device which comprises a stand column and a mounting box body, wherein the mounting box body is arranged on the upper portion of the stand column, the stand column is further provided with a mounting frame, and the mounting frame is provided with a sunshine duration sensor used for collecting sunshine duration, a temperature and humidity sensor used for collecting temperature and humidity data, and a rain gauge that is used for collecting rainfall; a solar power supply assembly is arranged on the mounting box body and is used for continuously supplying power to the sunshine duration sensor, the temperature and humidity sensor and the rain gauge. The invention further discloses a rice blast leaf blast condition forecasting method, according to the method, the rice blast leaf blast condition index is forecasted through a formula, so that the rice blast leaf blast disease grade is judged, managers can scientifically prevent and control rice blast according to the disease grade, unnecessary pesticide application is reduced, pesticide residue is effectively reduced, the pollution to the environment is reduced, and the rice blast prevention and control management efficiency and the rice planting benefit are effectively improved.

Description

technical field [0001] The invention relates to the field of crop disease prevention and control, and relates to the prediction and forecasting of rice plant diseases and insect pests, in particular to a device and a forecasting method for information collection device and forecasting method of rice blast leaf blast disease condition. Background technique [0002] Rice is one of the most important food crops in the world, and plays a very important role in world food production and food security. The planting area of ​​rice in my country accounts for 26% of the total arable land area, and its output is 43% of the total grain output. It is the largest grain crop in my country and an important basis for the country to implement the food security strategy. [0003] Rice blast is one of the common diseases in rice production, which can lead to an average annual loss of more than 5% of rice yield. From 1964 to 2013, rice blast occurred 13 times in Heilongjiang Province, with a lo...
