摘要
以红皮洋葱为试材 ,对呼和浩特地区春季播种育苗、初夏定植、秋季收获栽培方式下 ,洋葱营养生长期的生育规律进行了初步研究 ,结果表明 :幼苗期为 70 d～ 72 d,叶片生长期为 3 0 d～ 40 d,鳞茎胀大期为 3 0 d～ 3 5 d,全营养生长期为 14 7d～ 15 0 d。同时 ,对根系、叶片及鳞茎的生育规律作了初步研究探讨 。
The growth pattern of onion in vegetative growth period were studied.The results showed that seedling stage is 70_72 days,leaf growth period is 40 days,bulb enlargement period is 30_35 days,total vegetative period is 147_150 days.At the same times,the pattern of root system、leaf blade and bulb were preliminarily studied,it provided theory basis for culture methods.
