- 摘要:
- 干旱缺水是旱作农业最大的限制因素，品种对旱作玉米增产具有重大作用，筛选高产的玉米品种，有助于旱作粮食的持续增产与稳产。本试验以金穗4号为对照，选用12 个玉米品种进行品比试验。结果表明：甘玉系列品种产量均较低，联达169折合产量最高，为8 080.93 kg·hm-2，较对照金穗4号增产31.40%；敦玉16折合产量为6 621.06 kg·hm-2，较对照金穗4号增产7.64%，这2个品种综合性状好，适宜在试验区域内旱作区推广种植。
- Abstract:
- Drought and water shortage are the biggest limiting factors of dry farming,and variety plays an important role in increasing yield of dryland maize.Screening high-yield maize varieties is helpful to continuous increase and stable yield of dry cultivated grain.Taking Jinsui 4 as control,selection of 12 maize varieties were compared test.The results showed that yield of the Ganyu series was lower,yield of Lianda 169 was the highest(8 080.93 kg·hm-2),which was 31.40% higher than Jinsui 4,yield of Dunyu 16 (6 621.06 kg·hm-2) compared with the control Jinsui 4,increased by 7.64%.The 2 varieties had good comprehensive characters,suitable for planting in dry areas in the experimental area.
