[目的]介绍2BDQ-8型水稻直播机的研制与应用,为水稻机械化生产提供理论依据。[方法]将2BDQ-8型水稻直播机在江苏省几个县市地区进行田间生产性示范推广试验,并与人工插秧和机械化插秧相比较,考察其生产和经济状况。[结果]2BDQ-8型水稻直播机作业效率高,使用成本低,机直播作业比机插秧和人插秧节省约30%,综合效益显著。[结论]采用2BDQ-8型水稻直播机进行芽种直播是节本增效的水稻生产技术,值得推广应用。
[Objective] The research and application of 2BDQ-8 rice direct seeding machine were introduced in order to provide theoretical basis for rice mechanization production. [Method] The 2BDQ-8 rice direct seeding machine was used in field demonstration in several counties and cities in Jiangsu Province. Compared with artificial transplanting and mechanized transplanting, the 2BDQ-8 rice direct seeding machine was investigated for its production and economic status. [Result] The 2BDQ-8 rice direct seeding machine had the advantages of high operation efficiency, low using cost, saving about 30% of machine-transplanting and seedling transplanting with machine direct seeding operation, and the comprehensive benefit was remarkable. [Conclusion] Using 2BDQ-8 rice direct seeding machine for direct seeding of buds was a cost-effective rice production technique, which deserved to be popularized and applied.
