Abstract

Aiming at the problems of low land utilization and serious water waste in the existing wheat planting pattern, a two-high and two-low wheat high-low border spaced apart planting mode was proposed, and a high and low borders wheat no-till planter that can finish stubbing, fertilization, border construction, seeding and other tasks was designed. The design and analysis of the ship-type ridging device were carried out, and the construction process was simulated to determine the optimal parameters. A field test was carried out, the average sowing depth was 3.17 cm, the qualification rate was 95%, the standard deviation was 0.38 cm, and the coefficient of variation was 12.06%. The average value of the width of the seedling belt was 9.40 cm, the qualification rate was 91.67%, the standard deviation was 0.29 cm, and the coefficient of variation was 3.09%. The average height difference between the high and low borders was 9.26 cm, the pass rate was 100%, the standard deviation was 0.35 cm, and the coefficient of variation was 3.83%. The average width of the borders was 52.18 cm, the qualified rate of the border width was 100%, the standard deviation was 1.00 cm, and the coefficient of variation was 1.93%. The differences between each index and the theoretical design are small and meet the agronomic requirements.

Abstract in Chinese

针对现有小麦种植模式土地利用率低、水资源浪费严重的问题,本文提出了一种两高畦两低畦间隔分布的小麦高低畦种植模式,并设计了一种可一次性完成灭茬、施肥、构畦、播种等工作的高低畦小麦免耕播种机。对船式构畦器进行了设计和分析,并对构畦过程进行了仿真,确定了最优参数。田间试验表明,播种深度的平均值为3.17cm,合格率为95%,标准差为0.38cm,变异系数为12.06%;苗带宽度的平均值为9.40cm,合格率为91.67%,标准差为0.29cm,变异系数为3.09%;高低畦的高度差平均值为9.26cm,合格率100%,标准差为0.35cm,变异系数为3.83%;畦面宽度平均值为 52.18cm,合格率是100%,标准差是1.00cm,变异系数是1.93%,各项指标与理论设计差异较小且符合农艺要求。
