Design and experiment of the ditching device for wheat seeders capable of ditching sloped drainage furrows in rice-wheat rotation areas
《International Journal of Agricultural and Biological Engineering》2025年第1期154-164,共11页Quanyu Wang Ming Peng Jin He Caiyun Lu Chao Wang Zhenwei Tong 
funded by the China Agriculture Research System of MOF and MARA(Grant No.CARS-03);supported by the 2115 Talent Development Program of China Agricultural University.
To solve the problem of field waterlogging during wheat sowing in rice-wheat rotation areas,which causes sticky and wet soil,thus affecting the growth of wheat,this paper proposed a sloped ditching method based on las...
