摘要
内蒙古玉米品种试验采用直收直脱方式,增设了宜机收指标,为筛选高产、早熟、抗逆、宜机收获玉米新品种提供了科学依据。通过对宜机收指标的分析,进一步明确了宜机收玉米品种的选择重点为:产量、收获期籽粒含水率、收获期倒伏倒折率、籽粒破损率等,并提出改进建议,为不断完善玉米品种试验技术和宜机收玉米品种选用提供服务。
In Inner Mongolia, machinery direct harvest has been adopted in maize variety test. The index to determine the proper machinery harvest may help breeders to select genotypes not only showing high yield and early maturity, also with resistance in machinery harvest. Through a comprehensive analysis of those traits might have an impact in machinery harvest, our focus could be put on the following key agronomic traits: yield, grain moisture content, lodging rate and kernel damage rate. Suggestions were proposed to constantly improve our technical service in the selection of machinery harvest maize varieties and variety test.
