【摘要】 研究了沃得旋龙4LZ-3.0E等7款收割机机型,"Ⅲ"字形等3种收割作业行走路线,23%～32%分4个等级收割前土壤容积含水量,10～40 cm分5个等级留桩高度对机收再生稻再生季产量的损失差异;同时对4个因素的综合影响程度进行了比较分析。结果表明,土壤容积含水量和收割作业行走路线主要影响碾压比重和碾压行稻桩的萌芽及成穗,留桩高度影响再生季有效穗数形成,收割机机型(履带宽度、碎草装置)影响碾压比重和碾压行的产量贡献。4个因素对再生季产量损失影响程度依次降低,集成采用26%、留桩高度15～25 cm收割、按"Ⅲ"字作业行走路线、使用35 cm窄幅履带能使机收再生稻碾压产量损失率由41.7%降低至25.1%,减损效果明显,同时该技术还有继续研究优化空间。更多还原

【Abstract】 Experimental study on the Uuanlong Wode 4 lz-3.0 E 7 harvester models, and "Ⅲ" glyph three harvest homework walking routes, and 23%-32% in four grades before harvest soil volumetric water content, and the difference between the yield loss of the first season and the yield loss of the regeneration season was investigated with the pile height of 10-40 cm divided into five grades. The comprehensive influence of four factors on the basis of the comparison analysis was carried out, the results showed that the soil volumetric water content and harvest walk route mainly affected the proportion of RCC and germination and panicle formation, pile height affected the regeneration of season, harvester models(track width, broken grass machine) affected the rolling and rolling production line contribution proportion. Four factors, in turn, less impact on the regeneration season production losses, integrated use 26%, leave a pile height 15-25 cm to harvest, according to the word "Ⅲ" walking routes, 35 cm narrow tracks could make their ratooning rice rolling yield loss rate decreased from 41.7% to 25.1%, and the loss effect was obvious, at the same time the technology had room for continued research and optimization.更多还原
