Abstract

Abstract:

The purpose of this study was to explore the feasibility of interplanting silage maize in summer in alfalfa field in Huang-Huai-Hai region, in order to improve the forage productivity of alfalfa field and to explore a new planting pattern for efficient forage planting. In our study, silage maize was interplanted in two-cutting alfalfa field, which was the third year of sowing in Huang-Huai-Hai region. After interplanted silage maize in alfalfa field, the forage productivity, its influence on weeds and economic benefits before and after interplanting were studied. Compared with monoculture alfalfa, interplanting silage maize significantly increased the total forage yield, land equivalent ratio and total economic benefit of alfalfa field. Interplanting silage maize with alfalfa can effectively reduce the species of weeds and inhibit the growth of weeds in alfalfa field in high temperature and high humidity season in summer. This study provides a theoretical basis for interplanting silage maize in alfalfa field in summer in Huang-Huai-Hai region, and puts forward an efficient planting and application pattern of alfalfa planting.

Key words: alfalfa, silage maize, productivity, economic benefits, weed
