本文采用随机区组设计的方法,定株、定点、定时调查研究不同播种深度对水果玉米出苗、生育期、营养器官、生殖器官及产量的影响。结果表明:(1)随着播种深度的加深,出苗时间逐渐延长,出苗率提高,出苗整齐,产量性状值及产量增加;超过6 cm,随着播种深度的加深,出苗时间逐渐延长,出苗率降低,出苗不整齐,产量性状值及产量降低,株高增高,穗位提高,雄穗增长,雄穗分枝数减少。(2)播种深度对生育期、主茎叶片数、穗苞叶数和穗行数无影响。(3)新疆(南疆)阿拉尔垦区水果玉米适宜播种深度为6 cm。
In this paper, the method of randomized block design was used to study the effects of different planting depths on seedling emergence, growth period, vegetative organs, reproductive organs and yield of fruit maize. The results showed that: (1) With the deepening of sowing depth, the emergence time was prolonged, the emergence rate was increased, the seedling was tidy and the yield traits and yield increased. When the depth was deeper than 6 cm, the emergence time was gradually increased, Decreased, irregular emergence, yield traits and yield decreased, plant height increased, ear position increased, tassel growth, tassel branches decreased. (2) The sowing depth had no effect on the growth period, the number of main stem leaves, the number of ear bracts and the number of ear rows. (3) Suitable planting depth of fruit maize in Alar reclamation area in Xinjiang (southern Xinjiang) is 6 cm.
