| 摘 要： | 研究旨在探讨有效降低再生稻头季机收对蓄留稻桩的碾压损伤,提高再生季产量和生产效益。通过收割机履带窄幅化改制及宽窄行配套栽插大区比较试验,调查分析了宽窄行栽插对再生稻头季生物量的影响,验证了窄幅履带的减损效果。结果表明：相比等行距栽插,宽窄行栽插有效增加头季稻群体生物量、成穗率和产量;同时,宽窄行栽插有效降低履带对蓄留稻桩的碾压面积,减少机收碾压对再生季产量损失,实现增产增效。使用窄幅履带机收配套宽窄行栽插可实现两季总产量16309.22 kg/hm2,比对照增产2206.2 kg/hm2、增幅15.64%;宽窄行栽插实现再生季产量5897.87 kg/hm2,比对照增产807.41 kg/hm2、增幅15.86%;使用窄幅履带机收较宽履带减少再生季产量损失1288.16 kg/hm2,损失率下降了19.8%。该试验形成了相关的技术模式,具有成本低、易操作、效果好等特点,适合丘陵山区再生稻生产区推广应用。

| Abstract: | The purpose is to effectively reduce the rolling damage to rice stubble caused by mechanized harvesting in the main-crop (MC), and to improve the yield and productivity effect in the ratoon-crop (RC). Through the large area comparison test of narrowing harvester track and wide-narrow row planting, the effect of wide-narrow row planting on the biomass of the main-crop was investigated, and the damage reduction effect of narrowing harvester track was verified. The results showed that, compared with equal row planting, wide-narrow row planting effectively increased the biomass, panicle rate and yield of rice in main-crop. At the same time, wide-narrow row planting could effectively reduce the rolling area of the harvester track on residual stubble, reduce the yield loss of ratoon-crop caused by harvester rolling, and realize yield and efficiency increase simultaneously. The total yield of 16,309.22 kg/hm2 in the two seasons (MC+RC) could be achieved by adopting narrowing harvester track and wide-narrow row planting, which was 2,206.2 kg/hm2 higher than that of the control, with an increase of 15.64%. The yield of wide-narrow row planting in ratoon-crop was 5,897.87 kg/hm2, which was 807.41 kg/hm2 higher than that of the control, with an increase of 15.86%. Using narrowing harvester track could reduce the yield loss of ratoon-crop by 1288.16 kg/hm2 compared with the wide harvester track, and the damage rate decrease was 19.8%. The technical model established by the study is of low cost, easy operation and good effect, and suitable for promotion in ratooning rice production areas in hilly and mountainous areas. |
