我国北方洋葱采种周期很长,受冬寒伏雨、虫害的影响,采种难度很大.为解决洋葱采种技术,我们从1976年开始,在鞍山近郊太平大队进行了三年采种技术的试验研究,取得了较好效果,平均每亩采种量达100斤以上.试验表明:安全越冬、花期提前和防虫是获得洋葱采种成功的三大主要环节,而促使花期提前、躲过雨季则是采种成败的关键.一、适期栽植.1976年秋试验,栽期分8月25日、9月3日和9月15日,在相同秫秸覆盖条件下,翌春成活率都在96%以上.能够安全越冬.但以9月3日栽植的采种量最好,可见9月上旬为鞍山地区洋葱采种的栽植适期.
In the northern part of our country, the onions are planted for a long time, and it is very difficult to harvest seeds due to the frost and pests in the winter.In order to solve the problem of onion seed collection technology, we started the experiment of seed collection technology in Taiping Brigade in the suburbs of Anshan in 1976, And achieved good results, with an average of more than 100 kg of seed per acre.Experiments showed that: safe overwintering, early flowering and pest control are the three major links to the success of onion seed production, which led to the flowering ahead of time, The key.Ancrops planted in the autumn of 1976 test, planted on August 25, September 3 and September 15, under the same conditions of straw cover, the next spring survival rate of more than 96% in the safe overwintering However, the best planted seeds were planted on September 3, showing that the planting of onions in Anshan is suitable for planting in early September.
