摘　　要：本试验以甜高粱品种中科甜438为材料,研究裸地、地膜覆盖2种方式下不施肥和施有机肥、无机肥、无机肥+复合微生物菌剂共4种施肥水平对甜高粱产草量、营养品质和经济效益的影响,旨在为盐碱地甜高粱高效种植提供理论依据与技术指导。结果表明:与CK相比,覆膜和施肥处理均能缩短甜高粱的生长周期,改善农艺性状,提高产量、品质和经济效益。各处理中,覆膜条件下无机肥+复合微生物菌剂配施(MF;)增产增收效果显著,青贮产量、粗蛋白含量、相对饲用价值和经济效益分别为61.92 t/hm;、 8.15%、134.05、12 709元/hm^(2),均高于其它处理,比CK分别增加157.14%、23.67%、20.94%和175.86%,均达显著水平。综合认为,覆膜条件下无机肥+复合微生物菌剂配施是黄河三角洲盐碱地区甜高粱高效优质生产的适宜组合栽培措施。In this experiment, sweet sorghum(Zhongketian 438) was used as test material, and four fertilization levels of no fertilizer, organic fertilizer, inorganic fertilizer, inorganic fertilizer+compound microbial agent were set under two cultivation methods of film free and mulching film to explore their effects on grass yield, nutritional quality and economic benefit of sweet sorghum. It was expected to provide scientific guidance for efficient planting of sweet sorghum in saline-alkali land. The results showed that mulching film and fertilization could shorten the growth cycle of sweet sorghum, improve the agronomic characters and increase the yield, quality and economic benefits. In each treatment, inorganic fertilizer+compound microbial agent under mulching film(MF;) had significant effects on increasing yield and economic benefit. The silage yield, crude protein content, relative feeding value and economic benefit were 61.92 t/hm~2, 8.15%, 134.05 yuan/hm~2 and 12 709 yuan/hm~2, respectively, which were higher than the other treatments and significantly increased by 157.14%, 23.67%, 20.94% and 175.86% compared with CK. In conclusion, inorganic fertilizer + compound microbial agent under mulching film was a suitable planting mode for high-efficiency and high-quality production of sweet sorghum in the Yellow River Delta.
