水稻机械旱直播，即麦收后直接采用稻麦条播机作业种稻。从1994年开始试验示范，经1994、1995、1996年的试验表明（见表1），机械旱直播具有较好的增产、增效、省工特点，与手工移栽、塑盘抛秧比较，成本分别减少1440无人m2和726元／hm2，产值分别增加1245元／hm2和855元／hm2 Direct rice mechanical drought, that is, the wheat harvest directly after the use of rice and wheat drill sowing rice. Experimental demonstration since 1994, the 1994, 1995, 1996 experiments show (see Table 1), mechanical drought direct seeding has a better yield, efficiency, labor-saving features, compared with manual transplanting, plastic tray thrown seedlings, The costs were reduced by 1440 m 2 and 726 yuan / hm 2, respectively, with an increase of 1245 yuan / hm 2 and 855 yuan / hm 2 respectively
