雅玉青贮8号引种高产栽培技术研究

Introduction and High-yield Cultivation Technology of Yayuqingzhu 8

为促进十堰地区青贮饲料生产发展和服务养殖产业,通过引进青贮玉米品种雅玉青贮8号,从种植密度和追肥量2个方面研究其高产栽培技术。试验结果表明,雅玉青贮8号在十堰市适宜种植密度为67500株/hm2;在施足底肥条件下,追肥量为苗肥150kg/hm2、穗肥300kg/hm2时,生物产量最高,为67041.8kg/hm2。

To promote the development of silage production in Shiyan Area, and to service the cultivation industry, we introduced the maize silage variety Yayuqingzhu 8, and researched its high-yield cultivation technology from two aspects of planting density and dressing dosage.Results showed that the proper planting density of Yayuqingzhu 8 was 67 500 plants/hm 2 in Shiyan City.Under the condition of full base fertilizer, the biological yield was the highest (67 041.8 kg/hm 2) when topdressing was 150 kg/hm 2 seedling fertilizer and 300 kg/hm 2 ear fertilizer.
