摘　　要：为提高甘蓝大苗机械定植时的效率和成活率,以圆球形、高圆形、平头形3种类型甘蓝,品种YR中甘21、佳香、中甘107为试材,研究移栽前对幼苗叶片不同剪除量对剪除后机械化移栽情况和植株生长、产量及品质等方面的影响。结果表明,机械化移栽以幼苗第一片真叶叶柄基部到植株最高处的3/8和1/2剪叶量处理移栽速率最高、投苗率最好。根系活力以不剪叶处理最强,显著大于剪叶处理,其他各剪叶处理之间无显著差异;对后期的产量、品质等方面均无显著差异。综合考虑,以幼苗第一片真叶叶柄基部到植株最高处的3/8和1/2剪除量时,最适合机械化移栽;同时,以幼苗第一片真叶叶柄基部到植株最高处,剪除幼苗的部分叶片对甘蓝的生长发育无不良影响。In order to improve the efficiency and survival rate of mechanical planting of cabbage seedlings,three types of cabbage,spherical,high round and flat head,and YR Zhonggan 21,Jiaxiang and Zhonggan 107 were used as test materials to study the effects of different cutting amounts of seedling leaves before transplanting on mechanized transplanting after cutting,plant growth,yield and quality.Mechanized transplanting with 3/8 and 1/2 leaf cutting amount from the base of the first true leaf petiole to the highest point of the plant had the highest transplanting rate and the best seedling rate.The root activity of non-leaf-cutting treatment was the strongest,which was significantly higher than that of leaf-cutting treatment,and there was no significant difference among other leaf-cutting treatments.There was no significant difference in yield,quality and other aspects in the later period.Comprehensive examination,3/8 and 1/2 cutting amount from the base of the first true leaf petiole to the highest part of the plant seedlings from the base of the first true leaf petiole to the highest part of the plant had no adverse effect on the growth and development of cabbage.
