从国外经验来看,美国玉米行距基本是76 cm,极个别农场依然采用90 cm行距,是因为受到遗留收获机行距的制约(继承父辈的农场,播种机、收获机等机具行距为90 cm)。欧洲作物种植大多采用25 cm的倍数,一般条播作物为25 cm,如高梁是50 cm,玉米和棉花则为75 cm,主要是考虑机具的通用性。国外农艺主动适应机械化的实例甚多。灯笼状辣椒联合收获机采用的工艺是:以钢筋卷成的两个锥形的螺旋分别在主干的两侧第一个分叉下旋转,打击震动支叉使辣椒脱落。之后用气流吹运、去杂、装箱。原品种的第一个支叉的张角约为
According to foreign experience, the maize spacing in the United States is basically 76 cm. The number of rows in a few farms is still 90 cm. This is due to the restriction of the rowing distance of the remaining harvesters (the row spacing of 90 cm is inherited from the parents’ farms, planters and harvesters) . Crops in Europe mostly use multiples of 25 cm, generally 25 cm for planted crops, 50 cm for sorghum and 75 cm for maize and cotton, taking into account the versatility of the implement. Foreign agronomic initiative to adapt to the mechanization of many examples. The lantern-like pepper combine harvester uses the following process: two conical spirals rolled with steel bar are respectively rotated under the first furcation on both sides of the main stem, and the vibrating supporter is struck to make peppers fall off. After blowing with air, to miscellaneous, packing. The original species of the first leg of the opening angle of about
