Abstract The key management measures such as land preparation before sowing， variety selection， integrated sowing， weed control， water and fertilizer management， disease and pest control， mixed harvesting and storage， etc. were elaborated in detail. The technology of strip intercropping and mixed harvesting and storage of silage corn/feed sorghum in Ningxia irrigation area and its application effect were evaluated to define the suitable area for the promotion and application of the technology.

Key words Silage corn; Feed sorghum; Strip intercropping; Mixed harvesting and storage

飼草生產是草食畜牧業(yè)發(fā)展的基礎，受天然草原封育禁牧、草地生產力退化等影響，人工飼草已成為家畜養(yǎng)殖飼草的主要來源，人工飼草的供應能力、產品種類及產品質量成為草食畜牧業(yè)發(fā)展最為關鍵的影響因素[1]。（剩余5996字）
