我省大部分地区春旱失墒,除未秋耕的稻田、菜田需要进行春翻外,大多数旱田不宜春翻,不少地区在早春化冻时,采用缺口耙耙茬,碎土性能好,既不打乱表土层又能保墒.但是据1980年春调查,有的春耙作业不符合要求,严重影响了机械播种质量.经测查,用缺口耙耙茬的4块地选213个点,耙深1～6.5厘米的有52处,占24.4%,耙茬偏浅,特别是对漏风土,地硬,播种机开沟器不易入土.因此,有的生产队还得安排人站在播种机的播种斗和仿形架上,强制开沟器入土.耙深7～9厘米的有135处,
In most parts of our province, spring drought and no moisture, except for the unpolished rice fields and vegetable fields need to be spring-turned, most of the dry-land fields should not be spring-turned, and in many areas, they are not harrowed in early spring, , Neither disturbed the topsoil but also moisture, but according to the spring of 1980 survey, and some spring raking operations do not meet the requirements, seriously affecting the quality of mechanical sowing.After investigation, with the cut harrow stubble of the four selected 213 points , Raking depth of 1 to 6.5 cm of 52, accounting for 24.4%, rake stubble shallow, especially for leaking soil, hard, seeder opener is not easy to soil, therefore, some production teams have to arrange for people to stand Seeder sowing bucket and the contoured frame, forced opener into the soil rake depth of 7 to 9 cm 135,
