近年来随着中药材黄芪野生资源接近枯竭,人工种植产量低而不稳、品质差、利润低的问题,实现黄芪地膜覆盖机械精量穴播直播技术能够减少用工力度,精细用籽量,提高蓄水、保水、增温、提墒能力,促进黄芪生长发育进程,大幅提高黄芪的产量和质量,对定西区黄芪机械化生产、规模化种植及产业化发展提供参考。
In recent years, with the Chinese medicine Astragalus close to the depletion of wild resources, low and unsympathetic production yield, poor quality, low profit issues, to achieve mechanical precision of Astragalus Membrane Bunch broadcast technology can reduce labor intensity, the use of fine seeds, improve storage Water, water retention, warming, raising moisture capacity, promote the process of growth and development of Astragalus significantly improve the yield and quality of Astragalus, Astragalus Dingyuan mechanized production, large-scale cultivation and industrial development provide a reference.
