- 摘要:
- 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。
- Abstract:
- With long-day onion main varieties in Heilongjiang of‘Changrihuang’，‘Masa’and‘Hongyun’as materials，the growth rhythm of them were studied，to provided the basis for scientifically fertilizer management.The results showed that，3 onion varieties in the growth season，the growth of leaf length and sheaths appeared hurry first then slow trend；shoot fresh weigh showed a rapid growth trend after June 20th；horizontal and vertical diameter showed two enlargement periods；but underground fresh weight changed little for the first enlargement preriod (June 15th to June 30th)，while the weight of onion bulbs increased rapidly for the second enlargement.Fertilizer and water management could be carried out in accordance with the corresponding period of several key production.
