摘要
以西南生态区34个主栽品种为试验材料,采用间比法设计,通过不同生态区9个点的试验,在5 000株/667 m~2种植密度下,分析不同品种的特征特性、青贮产量及品质等性状,筛选出产量超过对照雅玉青贮8号8%以上的品种5个,分别是渝青506、渝青386、雅玉青贮988、迪卡008和北农青贮368,这些品种不仅产量高、品质优,且抗病抗倒性好,综合性状优良,适宜在西南地区作为青贮玉米推广种植。
Using 34 cultivars in southwest China as experimental materials, through 9 experiment places in different ecological areas in southwest China, the characteristics, silage yield and quality of different cultivars were analyzed under planting density of 5 000 plants/mu. Five cultivars with yields exceeding 8% of the control Yayu Silage 8 were selected, which were Yuqing 506, Yuqing 386, Yayu Silage 988, Dika 008 and Beinong Silage 368. These varieties not only have high yield and good quality, but also have good disease resistance, lodging resistance and comprehensive properties. They are suitable for planting as silage maize in southwest China.
