邵阳市水稻机械有序穴播试验报告OA

In response to adjustments in planting industry structure and the strategy of"storing grain in technology,"Shaoyang City conducted a comparative experiment between rice mechanical orderly hill-drop seeding(wet direct see-ding)and traditional mechanical transplanting from 2021 to 2025.The experiment was carried out at three pilot sites u-sing a large-plot comparison method,with unified varieties and technical procedures.Over five consecutive years,yield,labor input,and costs were monitored.The results showed that the mechanical orderly hill-drop seeding model saved an average of two labor units per 0.067 hm2 and reduced total costs by 200 RMB,while its yield was comparable to or slightly higher than that of mechanical transplanting.Based on this model,the mechanized ordered hill-drop see-ding technology for single-cropping rice has achieved an upgrade and iteration from experience-based to technology-driven practice,and has been formulated into a Hunan provincial group standard.It is adaptable to the climatic and soil conditions of Shaoyang City and meets the demands of large-scale and simplified planting.It provides a scientific basis for the technological upgrading of mechanized ordered hill-drop seeding of single-cropping rice in similar regions,possesses promotion value,and is of great significance for promoting regional agricultural modernization.In summary,the mechanized ordered hill-drop seeding model for rice is of wide popularization value and plays an important role in promoting the development of regional agricultural modernization.
