摘要
在大田养分胁迫条件下,通过比较11个玉米品种各指标的耐瘠程度,筛选出耐瘠性强的品种。结果表明:不同玉米品种各指标耐瘠指数差异显著,同一品种不同指标的耐瘠性有相同的趋势。贵卓玉9号、宣黄单4号耐瘠性最强,贵单9599、靖丰8号、保玉12号、金玉1号耐瘠性次之,织单5号中等耐瘠;4873、织金3号、贵单2785、荷玉1号耐瘠性较差。
To screen the good variety for barren resistance through the comparison of the resistance index of the 11 hybrid maize varieties under the field nutrient stress conditions. The results showed that the resistance indexes are obvious different by dif- ferent varieties and the different resistance indexes showed same trend in the one variety. Guizhuoyu No. 9 and Xuanhuangdan No. 4 have better barren resistance; guidan 9599, Qinfeng No. 8, Baoyu No. 12 and Jinyu No. 1 show less barren resistance; Zhidang No. 5 has middle barren resistance; the 4873, Zhijing No. 3, Guidang No. 2785 and Heyu No. 1 have poor barren resistance.
