Application device of color sensor in three-black and three-yellow cultivation method of late rice

Abstract

The invention relates to an application device of a color sensor in a three-black and three-yellow cultivation method of late rice, belonging to the technical field of application of Internet of things of new energy. A color sensor insert rod is inserted into a soil layer of a rice seedling bed, the color sensor which is mounted at the top of the color sensor insert rod is pointed at late rice seedlings and used for sensing three alternate changes in leaf blade colors, namely dark (black) and light (yellow) caused by application of a fertilizer water management measure in a paddy field, images of the leaf blade colors, which are captured by the color sensor are converted to electric signals, a transmitting antenna mounted on the color sensor is used for sending the electric signals into the sky, a receiving antenna is used for receiving the electric signals and then inputting into a computer processer to perform seedling observation colorimetric diagnosis by comparing with the experience in a three-black and three-yellow late rice management method of Chen Yongkang, fertilizer water management opinions are printed out by pieces of the paddy field and submitted to management staff of the paddy field to implement, and robust rice plants are cultivated by scientifically controlling the three changes in the leaf blade colors from the tillering stage to the booting stage of the late rice so as to increase the yield of paddy rice.

Description

technical field [0001] The invention relates to an application device of a color sensor in a method for cultivating three blacks and three yellows in late rice, and belongs to the technical field of new energy Internet of Things application. Background technique [0002] In 1951, Chen Yongkang, a rice farmer in Songjiang County, Jiangsu Province (now Songjiang District, Shanghai), created the country’s highest rice yield of 716.5 kg per mu at that time. During the cultivation, according to the three alternating changes of leaf color from the tillering stage to the booting stage, the thick 'black' and light 'yellow' changes, the corresponding fertilizer and water management measures are taken to achieve the goals of strong stems, large spikes, and full grains of rice plants, and to obtain the rice's high yield. Chairman Mao and Premier Zhou met Chen Yongkang many times and affirmed his experience in high-yield rice cultivation. [0003] After Chen Yongkang was transferred t...

Problems solved by technology

Some people want to learn from Chen Yongkang's three-black-three-yellow method of managing late rice. Due to insufficient production experience, they cannot intuitively grasp the alternating black and yellow leaves during the rice growth process.
