章丘大葱夏季栽培研究

Study on Summer Cultivation of Zhangqiu Green Onion

以章丘大葱大梧桐品种为试材,研究了夏季栽培中铺麦草、干湿栽和遮光对大葱株高﹑单株重等生长指标的影响。结果表明,章丘大葱在7-9月的夏季栽培中,铺麦草不利于大葱长高及产量增加,而合理的干湿栽及遮光处理可促进大葱长高和增重。利用遮光率30%的遮阳网遮荫30天、不铺麦草、干栽的栽培模式,可促进大葱生长,显著提高大葱单株重,具有较大增产潜力。

The experiment was conducted to study the impact of covering wheat straw , dried or wet planting and shading on the growth characters such as plant height and the individual fresh weight of Zhangqiu green onion Dawutong in summer cultivation .The results showed that during June -September ,covering wheat straw was disadvantage to the increase of plant height and yield , while reasonable dried or wet cultivation and shading treatment were benefit to their increase .The mode of shading with sunshade net for 30 days, not covered with wheat straw and dried cultivation could promote the plant growth and increase the individual weight , so it had higher potential to increase yield .
