Chemical fertilizer is the important measures to increase crops’ income. Our country is the large agricultural nation. But land per capita resource shortage.Precision agriculture in China is a sure way of agriculture.Variable fertilization is an important component of precision agriculture.Xinjiang is China’s major cotton production base.Cotton variables of fertilization of China agricultural research has important significance.At present there are many researchs for variable rate fertilization in our country.But many of them are research in control system.There is little research for cotton variable fertilization machine. So for the key technology of variable machinery equipment research and to cotton variable fertilization devices to have the important meaning.Can make better implementation of the variable rate fertilization.Because the variables fertilization device is variable fertilization system implementation parts, directly affecting the precision of variable rate fertilization fertilization.Decision variables fertilization system overall performance.Therefore, the variable fertilization cotton variable fertilization key technology and device research has important meaning and strategic significance.This paper in cotton variable machinery as the research object, According to the whole of the cotton variable machinery formed. Key components-row is fat,design. Through the experiment data. The main contents include:1The material properties of solid fertilizer, solid material properties of chemical fertilizer in FeiLiang influence.1Study the physical characteristics of the chemical fertilizer to row solid FeiLiang influence.Analyzing different physical state variables of the regulation of fertilizer fertilization row, research variables and fertilizer fertilization physical characteristics of the relationship.One solid fertilizer physical properties including loose sex, hygroscopicity, bonding, aerial sex, etc.; The method is used to study.2Establish virtual prototype, kinematics and dynamics analysis and computer simulation.3The control of variable rate fertilization system mechanical components wheeled row for the slot of fat structural parameters optimization and design.4The prototype test and trial.Certain geometrical dimensions of row of the different species, the fat conveying different proportion of the fertilizer, row fat the shaft speed and row between FeiLiang have different corresponding relation. Therefore on row fat device (slot wheel test, calibration, the use of various ratio compound fertilizer experiment data, through the curve fitting, obtains the ratio of compound fertilizer fertilizer the shaft speed and row row of the relationship between FeiLiang mathematical equations.Through this paper research work, Hope for cotton variable machinery cotton variable fertilization key technology and device research provides some help and theoretical basis. To provide technical reference cotton variable machinery.
