Abstract:

The production of silage from soybean and maize is increasingly valued in the development of animal husbandry in Jiangsu Province. To explore the suitable silage soybean varieties for maize and soybean strip intercropping, 76 soybean materials were compared with corn Kehua 666 in a ratio of 2∶2 strip intercropping mixed silage with soybean and maize single cropping single storage. The flowering period, plant height, and yield per unit area of soybean silage were analyzed, and suitable soybean varieties were selected. The results showed that under intercropping conditions, the flowering period of soybean had a relatively small impact, and the plant height was increased to varying degrees due to the influence of shading. The silage yield of late flowering soybean significantly increased, and the total silage yield significantly increased. In summary, the mixed cropping and harvesting silage model of silage soybean and silage maize not only improves land use efficiency but also increases silage yield, which has good prospects for promotion and utilization.
