摘　　要：试验选用2个野生大豆品种与青贮玉米进行混播栽培,研究其对青贮玉米饲草的产量及发酵后品质的影响。研究表明,野生大豆与青贮玉米混播可显著提高饲草产量,与对照组相比,饲草产量分别显著提高15.34%、16.53%;混播可提高饲草品质,可显著提高饲草粗蛋白质含量,与对照组相比,饲草粗蛋白质分别提高17.51%、23.52%。随着发酵时间的延长,粗蛋白质含量呈先升高后降低的趋势,粗脂肪的含量也随着发酵时间的升高,可溶性糖含量和粗纤维含量在发酵期间呈逐渐降低趋势,钙含量和磷含量在发酵期间无明显变化。Evaluated the current research was aimed to determine the effects of the mixed intercropping of two wild soybean(Glycine soja)with silage maize on the yield and nutrient composition of forage grass.The results showed that the mixed intercropping of wild soybean 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.Compared with the contrast,the forage yield was increased by 15.34%and 16.53%respectively;The crude protein content increased by 17.51%and 23.52%respectively compared with the contrast.With the gradual extension of fermentation time,the crude protein content increased first and then decreased.The content of crude fat also increased with the fermentation time.Soluble sugar content and crude fiber content decreased gradually during the fermentation period,while calcium content and phosphorus content did not change significantly during the fermentation period.
