Among the cereal crops, whole-crop wheat (Triticum aestivum L.) has become a common silage material in many countries of the world. However, there was little information about its planting methods. In order to obtain a optimum planting and utilization methods, this research investigated the effects of wheat-legume cultures on the fermentation quality and protein degradation of silage. In the present research, wheat, alfalfa (Medicago sativa L.), common vetch (Vicia sativa L.), milk vetch (Astragalus sinicus L.) and smooth vetch (Vicia villosa L.) were planted by monoculture and mixture of wheat with other one, and they were ensiled. There were no significant differences in pH value, lactic acid, acetic acid and butyric acid contents among all silages with wheat, either monoculture or mixture with legume (p > .05). The wheat-legume silages had higher lactic acid and lower butyric acid contents than their corresponding legume silages (p < .05). The non-protein nitrogen and peptide-N contents of wheat silage were significantly lower than those of wheat-legume silages (p < .05). Aminopeptidase and acid proteinase activities of monoculture legume and wheat-legume silages were significantly higher than those of wheat silage (p < .05). Overall, the chemical composition of forage has a greater influence on the fermentation quality and protease activity of silage compared to epiphytic microbes. The wheat-legume cultures could effectively improve the fermentation quality of silage compared to monoculture legumes and wheat.

小麦-豆科植物对青贮饲料发酵品质和蛋白质降解的影响

在谷类作物中，全麦（Triticum aestivum L.）已成为世界许多国家常见的青贮饲料原料。然而，关于其种植方法的信息很少。为了获得最佳的种植和利用方法，本研究调查了小麦-豆科植物培养对青贮饲料发酵品质和蛋白质降解的影响。在本研究中，小麦、紫花苜蓿（Medicago sativa L.）、紫云英（Vicia sativa L.）、紫云英（Astragalus sinicus L.）和紫云英（Vicia villosa ）L.) 采用单作和小麦与其他小麦混合种植，青贮。所有青贮与小麦，无论是单作还是与豆类混合，pH值、乳酸、乙酸和丁酸含量均无显着差异（p  > .05）。小麦豆类青贮比相应的豆类青贮具有更高的乳酸和更低的丁酸含量（p  < .05）。小麦青贮的非蛋白氮和肽-N 含量显着低于小麦豆类青贮（p  < .05）。单作豆类和小麦-豆类青贮的氨肽酶和酸性蛋白酶活性显着高于小麦青贮 ( p < .05)。总体而言，与附生微生物相比，草料的化学成分对青贮饲料的发酵质量和蛋白酶活性的影响更大。与单一栽培豆类和小麦相比，小麦-豆类培养能有效提高青贮饲料的发酵品质。
