摘要
按照生态条件及品种特点,进行了适宜齐齐哈尔地区青贮玉米品种及配套栽培技术的研究,并开展了青贮玉米适宜种植密度、玉米螟生物防治及适宜肥料3个方面的试验。结果表明,适宜齐齐哈尔地区种植的青贮玉米品种有3个,分别为:龙牧6号,适宜种植密度为6.75万株/hm^(2);龙巡32,适宜种植密度为6万株/hm^(2);阳光1号,适宜种植密度为6.75万株/hm^(2)。推荐选用赤眼蜂防治青贮玉米玉米螟,推荐使用常效肥作为青贮玉米肥料。
According to the ecological conditions and variety characteristics,this study carried out research and selection of suitable silage maize varieties and supporting cultivation techniques in Qiqihar area,and carried out three experiments of suitable planting density of silage maize,silage corn borer biological control technology,and suitable fertilizer for silage maize.The silage corn varieties suitable for planting in Qiqihar area were selected as Longmu No.6,with a suitable planting density of 67,500 plants/hm^(2);Longxun 32,with a suitable planting density of 60,000plants/hm^(2);Yangguang No.1,with a suitable planting density of 67,500 plants/hm^(2).Use Trichogramma biological control technology to control silage corn borer,and it is recommended to use normal fertilizer as a suitable fertilizer for silage corn.
