| 摘 要： | 根据田间玉米籽粒含水率来确定最佳机械粒收的时间，能为定边区域春玉米机械粒收技术的推广应用提供依据。通过不同时间收获取样，进行称重、脱粒和测定，了解当地主栽玉米品种的籽粒含水率变化。定边区域春玉米成熟后，经过田间站杆脱水时期，籽粒含水率可以控制在17%~22%之间。每年十月中下旬收获，可保证玉米机械粒收质量。

| Abstract: | Deciding optimal time for grain collection by machinery according to water content in maize can provide a basis for the extension and application of technology for spring maize grain harvest.The samplings of different harvest time were weighed and threshed,and then the change of water content in local maize was measured. After maturity of spring maize and dehydration period of standing stalks in Dingbian, the water content in grains could be controlled between 17% and 22%. Annual harvest in mid to late October, can ensure the grain quality of mechanical harvest. |
