油菜收获机械化技术按作业方式不同分为机械分段收获和联合收获两种。1.分段收获机械化技术技术概述:油菜分段收获是一种先割晒再捡拾、脱粒的收获方式,是针对我国南方稻—油或棉—油两熟或三熟轮作地区,由于茬口紧张,油菜生产仍以育苗移栽为主(占60%以上)的现实情况而研究开发的新技术。该技术具有损失率低、适收期长、腾地时间早的优点,特别对于株型大、分枝多、成熟度一致性差、一次收获难度大的育苗移栽油菜以及直 Rape harvesting mechanization technology according to different operating methods are divided into mechanical harvesting and harvesting two. 1. Section harvest mechanization technology Overview: Section rape harvesting is a kind of first cut and then pick up, threshing harvest is for rice in southern China - oil or cotton - oil two or three rotation crop areas, due to crop tension , Rapeseed production is still transplanting seedlings (accounting for more than 60%) of the reality of the research and development of new technologies. The technique has the advantages of low loss rate, long harvesting period and early leaching time, especially for transplanted rapeseed with large plant type, many branches and poor maturity consistency,
