保护性耕作体系及配套机械系统的研究

Research on Protective Cultivated System and its Supporting Mechanical System

保护性耕作是相对于传统耕作的一种新的耕作技术,是以作物秸秆还田和免耕、少耕技术相结合来进行农业生产的。松嫩平原纬度较高,种植制度多为一年一熟制,主要作物为小麦、玉米、大豆和水稻。为此,在探讨松嫩平原旱田秸秆还田模式的同时,对配套机械进行实验分析,并提出了相应的建议。

Protective cultivation which combines crop straw backing-field with no-tillage and mini-tillage technology to carry out agricultural production, is a new cultivated technology related to traditional cultivation. Songnen Plain is located in higher latitude area, in which the planting system is bringing in one harvest a year, and its main crops are wheat, corn, soybean, and rice. Hence, this paper discusses the straw backing field mode in dry farmland in Songnen Plain, and provides some advices based on analyzing its supporting machinery.
