摘要
[目的]研究宽幅精量播种对小麦形态特征、产量及产量结构的影响.[方法]采用大田试验示范方式,以苏麦188为材料,设2个处理,不重复,随机取样.[结果]宽幅精量播种处理播种深度一致、播量均衡;出苗快、整齐、苗数均匀;通风透光好,有利于控制基部节间长度和提高秸秆坚实度,增强抗倒伏能力;分蘖能力强,成穗率高,能提高有效穗数实现增产.[结论]宽幅精量播种可提高小麦播种质量与产量,但农机农艺配套技术需进一步研究.
Abstract
[Objective] To study effects of wide precision sowing on wheat morphological characteristics,yield and yield structure.[Method]Using field experiment demonstration way,taking Sumai 188 as test material,setting 2 treatments,Not repeating,Random sampling.[Result]Wide precision sowing treatment,consistent planting depth,seeding rate equalization;Emergence fast,neat,uniform number of seedlings;Good air and light,which will help control the length and improve basal stalk firmness,enhance the lodging resistance;Tillering ability,panicle rate,increase output and improve effective panicle.[Conclusion] Wide precision sowing can improve the quality and yield of wheat sowing,but supporting agricultural agronomic technology needs further study.
