| 摘 要： | 针对东北垄作区春季玉米免耕播种时施肥量大，正位垂直施肥易烧种，侧位施肥易堵塞的问题，研究设计了一种并列组合式种肥分施防堵装置。在玉米碎秆覆盖地试验结果显示，该装置土壤扰动量为17．8％，播种平均深度为44mm，施肥平均深度为78mm，种肥水平间距为32mm，垂直间距为34mm，种肥间距合格率达93％，提高了播种质量。与正位垂直施肥和前后侧位深施肥方式相比，该装置防堵能力强，种肥分施效果好。

| Abstract: | In view of the exist those main problems in the area of northeast ridge during the spring corn planting,such as large quantity of fertilizer,seed burned easily by the vertical fertilizing while lateral fertilization easily plugs openers,an undynamic anti-blocking mechanism and a paratactic separate application of fertilizer and seed mechanism were designed.The experiment in the field that covered with broken stalks of corn showed that the soil disturbance was 17.8%,planting depth was 44 mm,depth of fertiliz... |
