摘要
草田轮作是提高作物产量和改良土壤性状、实现土地可持续生产的重要措施。我国的草田轮作从魏晋南北朝开始就有记载。近年来的研究主要集中在草田轮作潜力及重要性、轮作效益、轮作模式及对土壤影响等方面。草田轮作既提高了粮食产量,又为家畜提供了充足的饲料,促进了养分循环,是实现农牧民增收及我国生态、经济和社会可持续发展的有效途径。
Forage and crop rotation are commonly recommended for sustaining crop production and enhan cing soil quality. Effects of forage and crop rotation in crop systems have been reported by many research ers from the Wei, Jin and Southern and Northern Dynasties period to present. Recent researches were focused on the potential, significance, profitability, mode and soil fertility of forage and crop rotation in China. Forage and crop rotation has numerous economic, ecologic and social benefits in the farming sys tem, which can increase crop and forage yields, enhance nutrient cycles and improve the living standard of farmers.
