摘要：

研究旨在探究黄淮海地区苜蓿田夏季套作青贮玉米的可行性，以期提高苜蓿田牧草生产力，为牧草高效种植发掘新的种植模式。在黄淮海地区播种第三年的苜蓿田刈割两茬后套作青贮玉米，探究在黄淮海地区苜蓿套作青贮玉米的牧草生产力、对苜蓿田杂草的影响及套作前后的经济效益。与单作苜蓿相比，苜蓿套作青贮玉米显著提高了苜蓿田的总产草量、土地当量比和总经济效益；苜蓿套作青贮玉米可有效减少夏季高温高湿季苜蓿田杂草的种类，抑制杂草的生长。为黄淮海地区苜蓿田夏季套作青贮玉米提供理论依据，提出了一种苜蓿高效种植推广应用模式。

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.
