Application And Theory Research On The Furrow-ridge-opener Of Water-application-furrow Seeder

Furrow-ridge-opener is the main working part of water-application-furrow seeder,The key requirement to the new design is the furrow opening,ridging,watering and fertilizing of soil completed at a time.In this paper,the structure and main parameters of furrow-ridge-opener are analyzed. The soil load characteristics of the ridge-opener were measured in the soil bin;The regression equation of the traveling force resistance was formulated.The working performace and characteristics of the water-application-furrow seeder unit were analyzed. The mathematical model of planting depth stability of the unit with linkage was established. The results introduced can be used for designing water-application-furrow seeder.The paper compares three kinds of watering and fertilizing ways,and finds the best way watering and fertilizing below the seeds. By the experiments,some main factors influenced watering effect were analyzed. The results show that watering volume,initial soil water content,and width of water ditch influenced the watering effect differently.
