本文总结了玉米品种丰大928的选育过程、栽培特征特性,分析了其高产栽培技术。该品种是以自交系LP6WC为母本,FGK01为父本杂交选育而成的早熟宜机收玉米品种。其在多年多点的区域和示范试验中,均表现出良好的稳定性和广适性,生育期128 d,株高273.4 cm、千粒重345.5 g;区域试验平均单产12 180~13 236 kg/hm²,抗倒伏性强,中抗茎腐病和丝黑穗病;籽粒粗脂肪含量4.05%、粗淀粉含量73.35%。其高产栽培技术包括抢墒早播,播深4~5 cm;适度密植,东北、华北地区种植密度以7.5万~8.5万株/hm²为宜;施肥以有机肥+氮磷钾肥为主,增施硼肥提高产量;病虫草害需综合防治,播后封闭除草,苗期防虫,大喇叭口期防治螟虫,授粉期防叶斑病;籽粒乳线消失后机械收获,以增产提质。本文为该品种推广种植提供参考。

The breeding process, cultivation characteristics, and high yield cultivation techniques of maize variety Fengda 928 were summarized. This variety was developed by crossing the inbred line LP6WC (female parent) with FGK01 (male parent), resulting in an early-maturing maize hybrid suitable for machine harvesting. In multi-year, multi-location regional and demonstration trials, it exhibited excellent stability and broad adaptability, with a growth period of 128 days, plant height of 273.4 cm, and 1 000-grain weight of 345.5 g. The average yield in regional trials ranged from 12 180 to 13 236 kg/hm2. It demonstrated strong lodging resistance, moderate resistance to stalk rot and head smut, and grain compositions of 4.05% crude fat and 73.35% crude starch. Key high yield cultivation techniques included: early sowing with sufficient soil moisture at a depth of 4-5 cm; moderate planting density of 75 000-85 000 plants/hm2 in Northeast and North China; fertilization based on organic manure combined with nitrogen, phosphorus, and potassium, supplemented with boron to enhance yield; integrated pest, disease, and weed management, including pre-emergence herbicide application, insect control at seedling stage, stem borer prevention at the bell stage, and leaf disease control during pollination; and delayed mechanical harvest after the milk line disappearance to maximize yield and quality. This article provides a reference for the promotion and cultivation of this variety.
