Abstract: In order to solve the existing problem of the repeat labor in multistage cultivating process, realize mechanized farming, lower labor intensity and increase productivity. Based on the theoretical analysis as well as experimental explore, YS-1GVFM-125A type combine machine of ridging, fertilizing and film covering has been developed matching the DF-151 or GN-121 type walking tractor. This machine is used to form ridge by up-cut rotary tillage, apply fertilizer by mixer, and cover film by pressure slot, and it could realize one off combined operation of ridging, fertilizing and film covering. The performance test and experimental verification showed that the performance indexes of this machine are accord with tobacco agricultural requirements, and it could very significantly increase productivity, lower labor intensity and activity cost, and had no significantly influence on yield and quality of Nicotiana tabacum. The operation of this machine doesn’t need to adjust the flue-cured tobacco fertilization measures about nitrogen rate, dressing tobacco and so on, and the predate time of the operation is inaptitude to exceed 30 days before transplantation, and the requirement of the soil moisture is slightly higher than general ridger.
