为了研究水稻联合收割机收获紫云英种子的应用效果,对比分析了机械收种和人工收种两种方法的种子产量、劳动效率、收割成本和经济效益。结果表明,与传统人工收种方法相比,机械收种降低了紫云英种子的损失率,比人工收种产量增加了92.7 kg/hm2,增幅为16.3%;提高了劳动效率,一台收割机一天收获的紫云英种子数量相当于18~20人一天的收种量;节约了紫云英留种生产的劳动成本,提高了紫云英种子生产的经济效益,采用机械收获紫云英种子比人工收种直接降低劳动成本2 175~3 000元/hm2,增加经济收入3 307~4 099元/hm2。该技术的推广应用对缓解南方稻区紫云英种子的短缺问题以及加快紫云英绿肥作物的发展具有重要的作用。
In order to study the application effects of the rice combine harvester harvesting the seeds of Astragalus sinicus, the seed yield, labor efficiency, harvesting cost and economic benefits of mechanical harvesting and artificial harvesting were compared and analyzed. The results showed that, compared with the traditional manual harvesting methods, mechanical harvesting reduced the loss rate of Aster seedlings, which was 92.7 kg / hm2 more than that of artificial seed collection, an increase of 16.3%; increased labor efficiency and a harvest The number of seeds of Astragalus mongolica harvested one day is equivalent to the harvest of 18 to 20 persons per day; the labor cost of producing the seeds of Astragalus sinicus is saved, the economic benefits of the production of the seeds of Astragalus mongholicus are enhanced, Seeds directly reduce labor costs by 2 175-3 000 yuan / hm2, and increase economic income by 3 307-4 099 yuan / hm2. The popularization and application of this technology has an important role in alleviating the shortage of asparagus seeds in the southern rice area and accelerating the development of the green-succulent plantation of the milk vetch.
