粮食作物生产过程中,收获是一个很重要的环节,季节性强,劳动强度大,农业技术要求高,作物成熟后,如不及时收获将造成很大的损失,以至丰产不丰收。改革开放以来,特别是“九五”期间,我国收获机械发展很快,我们拟从本期起对小麦、水稻、玉米收获机械分期作简略介绍。 In the process of food crop production, harvesting is a very important link. Seasonal, labor-intensive and high-tech agricultural requirements, if crops are not ripe enough, they will cause great losses and will not be bumper crops. Since the reform and opening up, especially during the Ninth Five-year Plan period, the harvesting machinery in China has developed rapidly. We intend to introduce the staging of wheat, rice and corn harvesting machinery briefly from this issue.
