块状紫山药新品种苏蓣2号选育及全程机械化栽培技术

摘要

The new bulk purple yam variety Suyu 2, which had high quality, efficien-cy and was suitable for production in a highly mechanized cultivation, was bred by special and was suitable for whole-course mechanized cultivation. Integrated with agricultural machinery and agricultural trait, four kinds of machines produced by two factories from Jiangsu and Shandong could complete 10 kinds of main production processes, including rotary til age, ridging, sowing, intertil age, topdressing, drug de-livery, weeding, hil ing, vine cutting and harvest. The work efficiency of single ma-chine was 4-5 hm2/d, and the production pattern got the cost saving and effective-ness increasing in the main yam producing area. The benefit reached over RMB 37 500 yuan/hm2 in special vegetable area. It was simple, feasible and easy to popu-larize the mechanization cultivation technique.%利用辐射诱变育种技术筛选出优质、高效、专用并适于全程机械化栽培的块状紫山药新品种———苏蓣2号。农机、农艺融合，应用苏鲁2个厂家生产的4种机械可完成旋耕、起垄、播种、中耕、追肥、施药、除草、培土、切蔓和收获等10种主要生产工序。单件机械的作业效率为4~5 hm2/d，山药主产区、特菜区节本增效为3.75万元/hm2以上。该全程机械化栽培技术操作简单，切实可行，易于推广。
