近十年来,国内外以紧凑型为特点的玉米杂交种不断涌现,并在生产上取得了明显的增产效果。生产实践证明,紧凑型比平展型玉米品种有着显著的增产潜力。发展紧凑型杂交种,是“八五”期间全国粮食生产的重点,也是调整种植业结构,开发粮食和饲料生产的一项重大措施。本文着重分析两类玉米杂交种在不同水肥条件下的表现,旨在探讨紧凑型玉米杂交种适推区及与之配套的栽培技术,为加速推广紧凑型玉米杂交种提供理论依据。
In the past ten years, hybrid corn varieties characterized by compactness both at home and abroad have been emerging continuously and remarkable yield-increasing effects have been achieved in production. Production practice has proved that compact than the flat-type corn varieties have a significant yield potential. The development of compact hybrids is the focus of national food production during the “Eighth Five-Year Plan” period. It is also a major measure to adjust the planting structure and develop food and feed production. This paper focuses on the analysis of the performance of two types of maize hybrids under different water and fertilizer conditions, aims to explore the compact maize hybrids and their matching cultivation techniques, in order to accelerate the promotion of compact corn hybrids provide a theoretical basis.
