野生大豆与青贮玉米混作对饲草产量及品质的影响

The Influence of the Mixed Intercropping of Wild Soybean(Glycine soja) and Silage Maize on the Yield and Quality of Forage Grass

通过在辽宁地区对2个野生大豆品系与青贮玉米进行混作栽培,研究其对饲草产量和营养成分的影响。结果表明:野生大豆与青贮玉米混作可显著提高饲草产量,二者混作收获物青贮后营养成分较玉米单播均有所增加,野生大豆品系LYD140116与青贮玉米在混播密度6.75万株/hm2条件下,饲草产量和品质可达较佳水平。

The current research was aimed to determine the effects of the mixed intercropping of wild soybean(Glycine soja)with silage maize on the yield and nutrient composition of forage grass in Liaoning area.The two G.soja varieties LYD140116 and LYD140916 and the maize variety Dongke301 were used as experimental materials.The results showed that the mixed intercropping of G.soja and the silage maize significantly improved forage yield and nutrient contents in mixed G.soja and maize silages as compared with their counter parts in the maize sole cropping system.Under the condition of the mixed sowing density of 67,500 strains/hm^2,the mixed intercropping of the G.Soja variety LYD140116 with maize achieved a higher yield and quality of forage grass.
