以“长日黄”、“马萨”、“红运”3个黑龙江省主栽长日型洋葱品种为试材,研究了其生长规律,从而为科学地进行肥水管理提供依据。结果表明:3个洋葱品种在生长季节内,叶长和叶鞘均表现出先急后缓的生长趋势;地上部鲜重在6月20日后呈现快速增长趋势;鳞茎的横、纵径表现出2个快速膨大的时期;但在第一个快速膨大期(6月15—30日)地下部鲜重变化不大,而第二个快速膨大期洋葱鳞茎迅速增重。生产上可根据这几个关键时期进行相应肥水管理。
In this study, three long-day onion cultivars, Long Day-long Yellow, Massa, and Red-blooming, were used as test materials to study their growth patterns and to provide scientific management for fertilizer and water management in accordance with. The results showed that within the growing season, the leaf length and leaf sheath showed a trend of first emergent and slow relaxation. The fresh weight of aboveground part showed a rapid growth trend after June 20, and the horizontal and vertical length of bulbs showed 2 However, in the first rapidly expanding period (June 15-30), the fresh weight of the ground did not change much, while the weight of onion bulbs increased rapidly in the second rapidly expanding period. Production can be based on these key period of the corresponding fertilizer and water management.
