谷子不同机械化收获方式比较试验白晓雷1柴晓娇1王显瑞1付颖1沈轶男1张姼1刘丹1郑添玮2李彩银3冯晓娟3宋青山3（1赤峰市农牧科学研究所，内蒙古赤峰024000；2赤峰市经济研究和投资促进中心，内蒙古赤峰024000；3巴林左旗鑫达种业有限公司，内蒙古赤峰025450）摘要针对谷子机械化收获过程中籽粒损失、谷壳破损、含杂质及对小米品质有负面影响等问题，本文以金苗K1谷子为试验材料，设置了不同机械一段式联合收获和谷子刈割后晾晒不同天数再机械化捡拾收获等7个收获方式处理，以籽粒损失率、含杂率、谷壳破损率及小米品质为衡量指标进行比较，并对刈割晾晒过程中谷粒含水量的变化进行观测。结果表明：谷子成熟时用稻花香4SX-3300稻麦割晒机割倒晾晒5d后，用雷沃GM100（4LZ-10M6）谷物收获机捡拾脱粒分段收获方式的效果最优，不但损失率最低，而且对小米色泽和口感品质的负面影响最小。关键词谷子；机械化；收获；品质；损失率中图分类号S515文献标识码A文章编号1007-5739（2023）07-0005-04DOI：10.3969/j.issn.1007-5739.2023.07.002开放科学（资源服务）标识码（OSID）：ComparativeExperimentofDifferentMechanizedHarvestingMethodsofMilletBAIXiaolei1CHAIXiaojiao1WANGXianrui1FUYing1SHENYinan1ZHANGShi1LIUDan1ZHENGTianwei2LICaiyin3FENGXiaojuan3SONGQingshan3(1ChifengInstituteofAgricultureandAnimalHusbandry,ChifengInnerMongolia024000;2ChifengEconomicResearchandInvestmentPromotionCenter,ChifengInnerMongolia024000;3BairinLeftBannerXindaSeedIndustryCo.,Ltd.,ChifengInnerMongolia025450)AbstractInviewoftheproblemsofgrainloss,huskdamage,impuritiesandnegativeimpactonmilletqualityduringthemechanizedharvestingofmillet,thispaperusedmilletJinmiaoK1asthetestmaterialtotestsevenharvestingtreatmentmodes,suchasone-stagecombinedharvestingthroughdifferenttypesofmachine,mechanizedpickingandharvestingaftermilletcuttinganddryingfordifferentdays,whichwerecomparedbyusingthegrainlossrate,impurityrate,chaffdamagerateandricequalityasindicators.Changesingrainmoisturecontentwereobservedduringtheprocess.Theresultsshowedthateffectofstagedharvestingwasthebest:themilletwascutdownbyDaohuaxiang4SX-3300riceandwheatwindrowerwhenmatureanddriedfor5days,thenitwaspickedupandthreshedbyLovolGM100(...
