多年生作物的研究进展

Research Progress of Perennial Crops

多年生作物是指生活周期年复一年,能多年生长,或地上部分在冬季枯萎,来年继续生长和开花结实的作物。多年生作物对于保持和改善农业生态系统,提高粮食产量有着重要作用。阐述了多年生作物在农业生产中的优势,探讨了多年生作物在农业生态环境中的利用价值,综述了多年生作物的创造途径,提出了多年生作物研究所面临的问题和实现的可能性,并对多年生作物的未来进行了展望。

Perennial crops that life cycle is year after year are many years of growth, which aerial parts are withered in winter, and the coming year is to continue growth, flowering and fruiting. Perennial crops have an important role to maintain and improve the agricultural ecosystem as well as increasing food production. This paper described the advantages of perennial crops in agricultural production, discussed the use value of perennial crops in the agro-ecological environment, summarized the creating ways of perennial crops and proposed the facing problems and tile possibilily of realization. At last, the future of perennial crops was prospected.
