Method for establishing yield monitoring and early warning model based on northern japonica rice

Abstract

The invention relates to the technical field of japonica rice yield monitoring and early warning, in particular to a method for establishing a yield monitoring and early warning model based on northern japonica rice. The method involves a yield monitoring system. The yield monitoring system is used for collecting image information of japonica rice within monitoring time and sending color images ofmature japonica rice as distinguishing image data to the data processing center; and the yield monitoring system is used for sending the average meteorological processing data in the monitoring areain each time period to the data processing center as meteorological data, and the yield monitoring and early warning model determines a prediction result of plant diseases and insect pests in the detection area according to the meteorological data and a predetermined meteorological data condition corresponding to the plant disease and insect pest model. A second database is established according to the yield statistical data and the real-time unit price, so that the predicted value of the total yield price in the detection area is determined according to the product of the average value of thestatistical data and the real-time unit price, the rice field yield can be effectively detected and early warned, and rice planting is facilitated.

Description

technical field [0001] The invention relates to the field of yield monitoring and early warning of japonica rice, in particular to a method for establishing a yield monitoring and early warning model based on northern japonica rice. Background technique [0002] Japonica rice is a variety of rice. Japonica rice needs short sunshine time, but has a long growth period, is relatively cold-resistant, has strong stickiness, short and round grains, high protein content, and good taste. The rice milled from japonica rice is called "japonica rice". In some places, "japonica rice" is called "rice". In fact, japonica rice is just a variety of rice. [0003] However, the yield of the existing japonica rice can only be determined when it is harvested. The monitoring and early warning equipment for japonica rice is not highly automated, and the yield of japonica rice cannot be estimated according to the meteorological environment and the environment in the paddy field. In view of this, w...

[0003] However, the yield of the existing japonica rice can only be determined when it is harvested. The monitoring and early warning equipment for japonica rice is not highly automated, and the yield of japonica rice cannot be estimated according to the meteorological environment and the environment in the paddy field. In view of this, we propose a Yield monitoring and early warning model based on northern japonica rice
