摘要：【中文】本发明公开了一种甘蔗、青贮玉米、小米3种作物轮作和间套作的方法，该方法是在一片土地上间套作甘蔗和小米或青贮玉米，每隔3‑5年就对宿根甘蔗地进行翻新，在原来种甘蔗的区域轮作小米或青贮玉米，在原来种小米或青贮玉米的区域轮作甘蔗，种小米或青贮玉米的区域是每种一茬小米后轮作一茬青贮玉米。因小米和青贮玉米的生长周期短，基本上可以实现每种植一期甘蔗就可以实现种植一茬小米和一茬青贮玉米，即实现每年收获一期甘蔗、一期小米和一期青贮玉米。因此，本发明的方法结合了轮作和间套作两种种植模式，使土地得到了轮作，避免了连作障碍，同时使土地得到了充分利用，提高了土地产出量，降低了土地成本，实现了甘蔗、青贮玉米和小米3种作物的丰收。 【EN】The invention discloses a method for crop rotation and intercropping of 3 crops of sugarcane, silage corn and millet, which comprises intercropping sugarcane and millet or silage corn on one land, renovating the land with perennial root sugarcane every 3-5 years, rotating the sugarcane in the original sugarcane-planting area, rotating the sugarcane in the original millet-planting area or silage corn-planting area, and rotating the corn after each round of millet-planting area or silage corn-planting area. Because the growth cycle of the millet and the silage corn is short, the planting of one batch of the millet and one batch of the silage corn can be basically realized for each period of planting the sugarcane, namely, the one-period sugarcane, the one-period millet and the one-period silage corn can be harvested every year. Therefore, the method combines two planting modes of crop rotation and intercropping, so that the land is rotated, continuous cropping obstacles are avoided, the land is fully utilized, the land output is improved, the land cost is reduced, and the harvest of 3 crops such as sugarcane, silage corn and millet is realized.
