摘要
为因地制宜地推广玉米耐密品种,以郑单958为对照,进行耐密品种比较试验。试验结果表明:在8个耐密品种中,坤博5588产量最高,生育期为127 d,适合在辽北大部分地区推广;立农24产量居第2位,生育期为128 d,也适合在辽北大部地区推广;铁源518产量居第3位,生育期为126 d,适合在整个铁岭地区大面积推广;其他5个品种的生育期居中,可根据抗倒伏、抗病、地区适应性等选择种植。
Experiment was conducted to compare and select density-resistant maize varieties with Zhengdan 958 as the control group. The results showed that in the 8 resistant cu]tivars, Kun Bo 5588 enjoys the highest yield, with a growth period of 127 D; and it is suit- able for plantation in most areas of North Liaoning. The yield of Li Nong 24 ranks second, with a growth period of 128 D, and it is also suitable for promotion in the north region; the yield of Tieyuan 518 ranks third, with a growth period of 126 D, and it is suitable for large area planting in the whole Tieling area; the other 5 cultivars can be selected and planted according to their lodging-resistance, disease- resistance, and area adaptiveness.
