- 摘要:
- 为提高大豆育种试验的准确性,降低劳动强度,针对垄三栽培小区试验农艺技术要求,设计了一种与之配套的垄上双行插装式排种器,并以作业速度和株距为影响因素对其工作性能进行了测试。结果表明:当作业速度分别为3.6、4.5、5.4 km.h-1,双行株距为5 cm时,其粒距合格指数≥85.17%、重播指数≤11.11%、漏播指数≤4.24%、变异系数≤20.69%;当双行株距为7.5 cm时,其粒距合格指数≥85.26%、重播指数≤9.47%、漏播指数≤5.26%、变异系数≤18.17%。两种工况下,排种器均达到JB/T51017-1999《中耕作物精密播种机产品质量分等》优等品标准的要求。该排种器为垄三栽培模式配套大豆小区精密播种机的开发奠定了基础。
- Abstract:
- In order to improve the accuracy of breeding experiment,reduce labor intensity,and meet the agricultural technologic requirements of three-ridge cultivation,an insert-metering device for ridge-double line was designed.The performance of the metering device was tested with different travel speeds and plant spacing as the influential factors.The results of the experiment indicated that when the travel speed was at 3.6,4.5 and 5.4 km·h-1 respectively and the plant spacing of double lines was 5 cm, the acceptability rate of plant spacing was equal to or greater than 85.17%,the multiples rate was equal to or less than 11.11%,the miss rate was equal to or less than 4.24% and the coefficient of variation was equal to or less than 20.69%;when the travel speed was at 3.6,4.5 and 5.4 km·h-1 respectively and the plant spacing of double lines was 7.5 cm,the acceptability rate was equal to or greater than 85.26%,the multiples rate was equal to or less than 9.47%,the miss rate was equal to or less than 5.26%,the coefficient of variation was equal to or less than 18.17%.In both conditions,the insert-metering reached the superior product standards of the JB/T51017-1999 Quality Classification of Single(Precision)Seeder for Intertilled Crops.The metering laid the foundation for developing the soybean sub-district precision planter of the three-ridge cultivation model.
