松嫩平原中南部不同基因型玉米品种宜机收特性研究

Study on the Characteristics of Mechanic Harvest of Different Genotype Maize Varieties in South Central of Songneng Plain

玉米机收是玉米生产发展的必然趋势,适宜机收的玉米品种是实现玉米机收的前提和基础。为促进黑龙江省松嫩平原中南部玉米实现粒收和构建节本增效栽培模式,本研究以松嫩平原中南部不同基因型玉米品种为研究对象,对比分析了不同基因型品种的出苗质量、植株和籽粒宜机收特性。结果表明:京农科728与和育187的粒收产量、机收籽粒破损率、籽粒含水量等机械化粒收相关性状最为合理,更利于直接进行机械化籽粒收获。

Mechanic harvest of maize is the inevitable development trend of maize production and the suitable maize varieties are the precondition and foundation of maize mechanic harvest.In order to promote the realization of grain harvest and establish the cultivation model of saving cost and increasing efficiency of south-central Songnen plain,the seeding quality and mechanic harvest characteristics of plant and grain of different genotype maize varieties were analyzed using different genotype maize varieties.The results showed that the characteristics related to mechanized grain harvest of Jingnongke 728 and Heyu 187,such as grain yield,breakage rate and moisture content were the most reasonable,which is more conducive to mechanized grain harvest directly.
