小麦机播具有播期短,下籽均匀,播深一致,达到苗全苗壮的作用。现将机播下种量的计算方法做以下介绍: 1.计算公式: 播种机每亩转数=66.7米~2/传动轮直径(米)×π×种籽箱长度米 (1) 播种机每20转下种量(斤)=每亩计划下种量(斤)+3/播种机每亩转数×20 (2) 注:“3”为修正数。因播种机在地头上要出现重复播种,故在计划下种量中加大3斤;另外因机轮转数过少误差较大,故在此应用20转的下种量来核算每亩实际下种量。知道了每20转的下种量,再将播种机传动轮支起来,播籽铧下面铺一麻袋,将种籽倒入
Wheat machine sowing sowing a short, uniform seeds, sowing the same line, to achieve the full seedling Zhuang Miao role. Now the sowing method of planting the amount of the following description: 1. Calculation formula: sowing machine per mu = 66.7 m ~ 2 / drive wheel diameter (m) × π × seed box length meter (1) seeder Quantity per kg (kg) = planted per mu (kg) + 3 / rev per acre × 20 (2) Note: “3” is the correction. Due to seeder in the ground to appear repeated sowing, it plans to increase the volume of 3 kg; the other due to the wheel rotation less too much error, so the application of 20 rpm under the amount to calculate the actual acre Amount. Know the next 20 kinds of seed volume, and then planter drive wheel up, sowing seeds below the shop a sack, the seeds into
