基于轻简化嫁接装置的冬瓜种苗嫁接试验研究OA

Large-scale production of grafted wax gourd seedlings relies heavily on professional grafting workers,resulting in high labor costs and difficulties in coordinating grafting schedules.To address these challenges,this study evaluated a low-cost,simplified grafting device that enables ordinary workers to perform grafting operations.The productivity,grafting success rate,healing and survival performance,and economic feasibility of the simplified grafting operation were investigated and compared with those of professional grafting workers.The experimental results showed that,after one week of training,ordinary workers using the simplified grafting device achieved a grafting productivity of 443 plants/h per operator and a grafting success rate exceeding 96%.Among the tested operating arrangements,a single operator using the simplified grafting device achieved the highest grafting productivity and approached the operational performance of professional grafting workers.The healing and survival rate of grafted seedlings produced by trained operators using the simplified devices exceeded 95%,showing no significant difference from that of seedlings produced by professional grafting workers.Furthermore,compared with the ground-covering method,the use of a healing room did not provide a significant improvement in the healing and survival rate of grafted seedlings.Economic analysis showed that replacing professional grafting workers with ordinary workers operating the simplified grafting devices could reduce labor costs by more than 50%.Under the conditions evaluated in this study,the investment in the equipment could be recovered within 1-2 years,with longer annual grafting periods resulting in shorter payback periods.Therefore,the adoption of low-cost,simplified grafting devices can reduce labor costs while improving the ability of seedling enterprises to independently manage grafted seedling production.It can also reduce dependence on external professional grafting teams,mitigate production disruptions caused by the unavailability of such teams,and improve the scheduling and quality control of grafted seedling production in large-scale nurseries.
