红皮洋葱新品种‘西葱1号’的“一道清”高效栽培技术研究

将“一道清”的高产长效施肥技术在激光诱变选育出的红皮洋葱新品种‘西葱1号’上施用，通过与’常规施肥试验的对比，得出使用这种施肥技术可显著提高肥料利用率25％左右，能满足洋葱生长全过程的需要；还能降低洋葱早期抽薹率50％左右，改善洋葱品质，产量提高5％以上，施肥上用工减少5／4以上。在生产应用上有极好的前景。

High Effective Cultivation Technique of Applying"Yidaoqing"to New Red-peel Onion Variety 'Xicong-1'

We have carried out an experiment of the high yield and long effective cuhivation technique of applying ＂Yidaoqing＂ to a new red-peel onion variety ＇Xicong-l＇ bred through laser-radiation. Compared with its conventional control, the technique can increase the fertilizer utilization by 25%, meet the needs of the whole growth of the variety, decrease its early sprouting rate by about 30%, raise its production by 5%, reduce labor force by 75% and improve its quality. This technique shows a wonderful applying prospect in future production.
