油菜机械化收获方式的选择

我国油菜机械化收获主要有两种方式-分段收获和联合收获,两种收获方式的选择恰当与否是影响油菜机械化生产的重要因素.而收获方式的选择,受到油菜种植方式、气候条件、适宜的收获期等条件的影响.为此,在全面考虑收获条件及适应性、经济性、作业质量等影响因素的基础上,对两种收获方式进行了优、缺点比较,进而对我国南、北方油菜产区机械化收获方式进行了选择.分析表明:我国油菜机械化收获需要因地制宜地采取适当的收获方式,而不应是全部采用联合收获;分段收获方式具有适应性强等多种优势,应加强研究,开发相应的机械装备.

The Choice of Rape Mechanized Harvest Methods

There are two main methods of rape mechanized harvest in China:subsection harvest and combine harvest.The choice of harvest methods will greatly influence the output of rape mechanized production and is decided by planting,climate and adaptive harvest period.In the perspective of adaptability,economical efficiency,and operational quality,this paper compared the advantages and disadvantages of different harvest methods.It put forward the proposal of rape harvest method in South and North China.After analysis,it made the conclusion that we need to adjust measures to different local conditions in the rape mechanized harvest,subsection harvest extend adaptive harvest period that result in directly operation area.And we need to develop relevant mechanical equipment.
