英文摘要： The applied project plans to study the soil-hole-drilling component and soil-fertilizing component with biomimetically geometrical structure and ultra high molecular weight polyethylene (UHMWPE) learning from the geometrical structure and hydrophobic nature of the cuticle of soil-burrowing animals in order to reduce soil adhesion and forward resistance premise the quality of soil hole by soil-hole-drilling component and injecting quality for component for injecting fertilizing liquid in soil. So, this study will be of an important theoretical value and practical significance. The two type of components consist of subsoiler for soil-hole-drilling component and its expander or the injecting part for injecting liquid. Biomimetic drag reduction theories and techniques of subsoiler and anti-adhesion and drag reduction techniques of the expander for soil-hole-drilling component and the component for injecting liquid in soil will be established. The research work is an important extension of efficiency-high and energy-saving biomimetic theories and techniques of soil-engaging components of agricultural machinery. The research route is clear and innovative; the application of biomimetic technique in agricultural machinery has its self feature; the research results of the project will have specific utilization. This project puts forward compositive anti-adhesion and drag reduction techniques of biomimetically geometrical structure and UHMWPE utilizing in the soil-hole-drilling component and soil-fertilizing component and, so, the research content is innovative; the techniques for soil-hole-drilling component and soil-fertilizing component have compositive innovation and are in foreland of the anti-adhesion and drag reduction of biomimetically geometrical structure of agricultural machinery.
