为了解决烟草耕整地与施肥、覆膜时多道工序重复用工的问题,实现机械化作业,降低劳动强度,提高生产效率。通过理论分析和试验探索,研制出与东风-151型或工农-121型手扶拖拉机配套的YS-1GVFM-125A型起垄施肥铺膜联合作业机。该机采用反转旋耕起垄、搅笼输送施肥、压槽盖土覆膜,能在平板田上进行一次性起垄、施肥、覆膜联合作业。通过性能检测和试验验证,该机作业效果基本能达到烟草农艺要求,能极显著提高作业效率、降低劳动强度和作业成本,且对烤烟产质量不产生明显影响;使用该机进行耕作,无需调整施氮量、氮肥基追肥比等烤烟施肥措施,提早施肥耕作时间不宜超过移栽前30天;但该机对耕作土壤水分要求较普通起垄机稍高。
In order to solve the problem of repeatedly using labor in multi-channel process of tobacco cultivation and fertilization and film mulching, mechanization operation, labor intensity reduction and production efficiency are improved. Through the theoretical analysis and experimental exploration, YS-1GVFM-125A ridge-type fertilizer and fertilizer combined operation machine matched with Dongfeng-151 or worker-peasant-121 walking tractor is developed. The machine uses reverse rotation Ridge ridging, stirring cage transport fertilization, pressure trough cover soil cover, in the flat field on a one-time ridging, fertilization, laminating joint operations. Through the performance testing and test validation, the machine can basically achieve the operational effect of tobacco agronomic requirements, can significantly improve operating efficiency and reduce labor intensity and operating costs, and the quality of the production of tobacco does not have a significant impact; the use of the machine for farming without adjustment Nitrogen fertilizer, nitrogen fertilizer top dressing ratio and other flue-cured tobacco fertilization measures, early fertilization tillage time should not exceed 30 days before transplanting; but the machine requirements of farming soil moisture slightly higher than ordinary ridging machine.
