Abstract: In order to investigate the effects of mulching cultivation on production performance and nutritional quality of different varieties of maize, we conducted an experiment using a split zone experimental design, the main cultivation methods were film mulching and non-film mulching, with 7 silage corn varieties (‘Jingke Silage 932’‘Simon Silage 707’‘Heyu 36’‘Heyu 9566’‘Dika 625’‘Dika 667’ and ‘Beinong Silage 208’) as sub areas. The results showed that under mulching cultivation condition, the ear weight (324.00 g), fresh yield (61.71 t·hm-2), and CP (8.52%) and EE (2.76%) contents of the tested silage corn were significantly higher than those without mulching; ‘Heyu 36’‘Heyu 9566’ and ‘Beinong Silage 208’ showed higher production performance under mulching and non-mulching cultivation conditions compared to other tested varieties, and ‘Heyu 36’ and ‘Heyu 9566’ had significantly higher CP, EE content, and RFV values than other corn varieties, demonstrating significant variety advantages. The interaction between mulching and non-mulching in silage corn varieties: ‘Heyu 36’‘Heyu 9566’ and ‘Beinong Silage 208’ showed significantly higher fresh grass yield, CP content, and RFV value than other tested varieties. In summary, film mulching cultivation could improve the production performance and nutritional quality of silage maize, and ‘Heyu 36’ ‘Heyu 9566’ and ‘Beinong Silage 208’ had the best comprehensive performance under the condition of film mulching cultivation, and were suitable for promotion and planting in the arid plateau area of eastern Gansu.

摘要: 本研究采用裂区试验设计,以覆膜和不覆膜两种栽培方式为主区,以7个青贮玉米品种(‘京科青贮932’‘西蒙青贮707’‘禾玉36’‘禾玉9566’‘迪卡625’‘迪卡667’和‘北农青贮208’)为副区,研究覆膜栽培对不同品种青贮玉米生产性能和营养品质的影响。结果表明:覆膜栽培条件下青贮玉米的鲜果穗重(324.00 g)、鲜草产量(61.71 t·hm-2)以及CP(8.52%)和EE(2.76%)含量均显著高于不覆膜;‘禾玉36’‘禾玉9566’和‘北农青贮208’在覆膜与不覆膜栽培条件下的生产性能均高于其他参试品种,且‘禾玉36’和‘禾玉9566’的CP,EE含量和RFV值显著高于其他玉米品种;交互作用下,‘禾玉36’ ‘禾玉9566’和‘北农青贮208’的鲜草产量、CP含量和RFV值均显著高于其他参试品种。覆膜栽培能提高青贮玉米的生产性能,并改善其营养品质,且‘禾玉36’‘禾玉9566’和‘北农青贮208’在覆膜栽培的条件下综合表现最优,适宜在陇东旱塬区推广种植。
