Embodiment 1
[0044] Taking rice at the seedling stage in Northeast China as an experimental crop, the system provided by the invention is used to solve the problem of automatic fertilization according to changes in the crop growth environment. The system includes a crop growth environment change detection module, a central analysis control module and an automatic fertilization module; wherein the crop growth environment The change detection module measures the information value of the crop growth environment, including as an environmental temperature detection device. The central analysis control module includes an environmental temperature change result analysis module, an operation module, and an input module. The input module is connected to the environment temperature change result analysis module and the operation module; The environmental temperature change result analysis module receives the environmental information value and compares it with the environmental temperature standard va...
Embodiment 2
[0050] Taking wheat at the seedling stage as the experimental crop, the environmental soil humidity was detected to be 2%; the standard value humidity of wheat at the seedling stage was 5%, and the environmental change result E was obtained through the central analysis and control module. Standard value, where crop-related information P = (10 mu, seedling stage, wheat)
[0051] The operational formula in the central analysis control module is: Said W = water supply per mu is 2m 3 ; said T=60 minutes; said M=water pipe sprinkler irrigation; the above-mentioned water supply information is transmitted to the automatic irrigation module, and the automatic irrigation module irrigates the crops according to the water supply information, and sprays water to the seedling wheat.
[0052] When the soil moisture is reduced to the semi-lethal humidity of the crops, the wheat mortality rate is 4% through automatic irrigation of an appropriate amount of water, which greatly reduces the whea...
