摘要
在低投入农业系统中,特别是在地中海盆地,一年生饲料豆科植物和禾草混合种植是支持可持续饲料供应的一种常见策略。在埃及北部进行的一项为期两年的实地研究中,采用3个重复的分割区设计,研究了四组不同混合率的苜蓿、小黑麦和燕麦的生产力和营养价值,分别作为单一栽培和豆类-草二元混合栽培。试验混合速率为:1;2. 0%草(G) + 100%三叶草(BC)25% g + 75% bc, 350% g + 50% bc, 4。75% G + 25% BC, 5。100% g + 0% bc。三叶草与小黑麦混合在三切鲜产量上最高,而BC与燕麦混合在一切和二切鲜产量上都较好。粗蛋白质(CP)含量以BC单株和三叶草-小黑麦混合液最高(75%:25%)。总体而言,禾草改善了混合饲料中干物质积累和碳水化合物成分,其中小黑麦优于燕麦。可消化有机质(DOM)最高的是纯BC林分和75% BC混合林分。值得注意的是,被测试的草在第三次修剪后没有再生;因此,第四次切割仅由BC组成。DOM的变化最依赖于CP含量的变化。结果表明,BC与小黑麦在75%:25%的混合比例下,产草量高,品质优于其他混合比例。
Mixture cropping of berseem clover with cereals to improve forage yield and quality under irrigated conditions of the Mediterranean basin
Mixture cropping of annual forage legumes and grasses is a common strategy to support sustainable forage supply in low input agricultural systems, especially in the Mediterranean basin. In a two-year field study, conducted in Northern Egypt, productivity and nutritive value of four cuts of berseem clover, triticale, and oat, cultivated as monocultures as well as legume-grass binary mixtures, with variable mixing rates, were investigated using a split plot design in three replicates. The tested mixing rates were: 1. 0% Grass (G) + 100% Berseem clover (BC), 2. 25% G + 75% BC, 3. 50% G + 50% BC, 4. 75% G + 25% BC, and 5. 100% G + 0% BC. Berseem clover mixtures with triticale produced the highest significant 3rd cut fresh yield, while BC mixtures with oat were superior at the 1st and 2nd cut's fresh yield. Crude protein (CP) content was highest in BC monocultures and clover-triticale mixture (75%:25%). Grasses, in general, improved the dry matter accumulation and carbohydrate components in the forage mixtures, with triticale being superior to oat. The significantly highest digestible organic matter (DOM) was a character of the pure BC stands, and mixtures with 75% BC. Noticeably, the tested grasses did not regrow after being cut for the third time; thus, the fourth cut was composed only of BC. Variations in DOM were most dependent on variations in CP content. Results revealed that mixtures of BC with triticale at 75%:25% mixing rate produced high forage yield with improved quality than the other mixtures.
