| China is a large country in population and agriculture.Rice is one of the main grain crops in China.The area of rice sown in China accounts for 1/4 of the total area of grain crops in the whole country.The annual output accounts for more than half of the total grain output of the whole country.With the improvement of people's living standard,the production and quality of rice need to be further improved.The traditional small farm production has encountered many bottlenecks to improve the output and quality.It is not guaranteed that the information of controlling temperature,fertilizer,water level and soil quality to achieve high yield is not guaranteed.However,with the development of science and technology,these bottlenecks can be solved by the systematization,mechanization and information of agriculture.Especially in recent years,the agricultural information technology developed greatly by the state has combined modern information technology with the agricultural industry,using computer,information storage and processing,communication and network.Information technology,such as artificial intelligence,has the characteristics of systematic,efficient development and utilization of agricultural technology to improve the stable growth of output and quality.Three key stages of agricultural informatization.It is the collection of all kinds of agricultural information,the accurate transmission of information and the processing of information.In addition,the research of special materials and all-optical control of nonlinear optics has become a hot spot in the field of optical research.In recent decades,the study of optical solitons has been a hot spot in the field of nonlinear optics.These research results are especially accurate transmission of all optical switches,beam control,nonlinear transmission and so on.It is of great reference value to lose the aspect.In this paper,the lossless transmission of agricultural information is studied by using nonlinear optical material control characteristics.In this paper,based on the nonlinear Schrodinger equation of optical information transmission,the transmission characteristics of agricultural light information in special nonlinear media are studied by numerical method.Optimize the accurate transmission of agricultural information.Firstly,the transmission characteristics of the negative refracting material in special transmission medium are analyzed theoretically.Secondly,the nonlinear Schrodinger equation is solved by the numerical analysis method.Some stable optical modes in the nonlinear transmission medium are discussed and obtained,and the dynamic mechanical problems of the transmission are studied.Finally,the negative refraction mediators are discussed.The control characteristics of the precise transmission of light information.There are two main aspects in this study:(1)the Schrodinger equation for the transmission of optical information in a nonlinear medium is analyzed,and the influence of the negative refraction medium on the information transmission is discussed.The dielectric constant and the permeability of the negative refraction medium are negative at the same time,and the refractive index of the medium is less than zero.A negative refraction occurs when a beam of light is incident from a conventional material(a medium with a positive refractive index greater than zero)to the interface of a negative refraction medium,and the refraction light is on the same side of the interface normals with the incident light.This leads to many characteristics that are conducive to the accurate transmission of optical information.(2)the distribution Fourier method is used to analyze the characteristics of optical information transmission in conventional material transmission and negative refraction materials.By changing the characteristics of the optical information waveform and the incident angle,it is found that the transmission characteristics in the negative refracting material are obviously superior to the conventional materials,and the accurate transmission of the optical information in the medium is improved.Lose.At the same time,the control characteristics of negative refraction material for optical information transmission are also studied.Through the analysis of the transmission of light information with special materials,the nondestructive transmission of the agricultural information of rice,such as light,temperature,water and pH value during the growth of rice,has been obtained,which is a guarantee for high quality and high yield of rice. |
