大垄侧深分层施肥装置的设计与试验
Design and Experiment of Lateral Deep Layered Fertilization Device of Big Ridge
摘要
Abstract
In view of the problems such as excessive furrow width and uncontrolled stratified fertilizer amount during the operation of mechanical parts of fertilization.A lateral deep layered fertilization device of big ridge was designed.The structure and key components of the device were designed according to the operation requirements.The grooving disc was optimized to be a corrugated grooving disc with strong hardness,wear resistance and corrosion resistance.The grooving depth was in the operating range of 150-280 mm.The ditch width of the hook was 20 mm,and the mechanism mainly ensures the width of the ditch and protects the effect of layered fertilization from being squeezed and deformed by the soil.The test results showed that:in the application of layered fertilization,the width of the trench opened by the device was smaller than that opened by the existing trench,which reduced the disturbance to the soil structure.The coefficient of variation of shallow layer was 3.7%at different speeds,and that of deep layer was 7.9%,which was less than 10%of the coefficient of variation required by the national standard.The working speed had no significant effect on the fertiliza-tion ratio of the layered fertilization device,and the depth of fertilization was 90 mm in shallow layer and 200 mm in deep layer,which met the design requirements of the layered fertilization depth.This study provided reliable technical equip-ment for fertilization ditching and fertilizer layering,and had certain popularization and application value.关键词
