白鹤玉米是“辽字号”品种,我省引进栽培,主要用于刈割、青贮,作为牲畜饲料。由于该品种生育期长(辽宁省当地为135～140d),在我省制种受地理纬度限制,很难满足生育期积温要求,常规栽培管理进行种子繁殖均未获得成功。 为探讨白鹤玉米在我省自繁制种问题,我们这些年来进行跟踪试验和多点调查,重点探讨在生氏季节内缩短生育期情况下的栽培技术,达到
Crane corn is “Liao font” varieties, the introduction of cultivation in our province, mainly for cutting, silage, as livestock feed. Due to the long growing period of this variety (135-140 d in Liaoning province), the seed production in our province is limited by the geographical latitude, so it is difficult to meet the requirement of accumulated temperature during growing period. Conventional cultivation and management of seed breeding has not been successful. In order to investigate the problems of white crane corn in the province since its birth, we conducted follow-up tests and multi-point surveys over the years, focusing on the cultivation techniques that shorten the growth period within the growth season and achieve
