多年来,四川汉川县农民摸索了用换沟移厢的办法种植棉花(在麦茬行中开新沟,将土搬过棉行填平旧沟),较好地解决了肥土流失、棉株倒伏、不耐旱等问题。但是用人工换沟移厢劳动强度大,工效低,特别是春耕生产、麦收季节,农活争劳力,群众迫切需要一种换沟移厢机械。去年汉川县农机所初步研制出“棉田换沟移厢机”。该机与工农-12手扶拖拉机的牵引座相挂结。有换沟、灭茬、埋肥、移厢及改善土壤结构的作用。
Over the years, Hanchuan County, Sichuan Province, farmers fumbled with the method of shifting ditches to grow cotton (in the stubble row to open a new ditch, the soil moved across the cotton line fill the old ditch), a better solution to the loss of soil, cotton Lodging, no drought and other issues. However, the manual labor to change the box for the labor intensity, low efficiency, especially in spring production, wheat harvest season, agricultural labor struggle, the masses urgently need to change a groove moving box machine. Last year, Hanchuan County Agricultural Machinery initially developed The machine and workers-peasants -12 tractor traction phase hanging. There are trenches, stubble, buried fertilizer, moving the box and improve the role of soil structure.
