不同化控药物对百玉1号植株部分性状及产量的影响
以百玉1号为材料,分别在玉米拔节期(10片可见叶)喷施缩节短、恐高、黄金玉配3种化控药物,并在大喇叭171期、抽雄期、灌浆期、成熟期调查玉米株高、单株叶面积、茎粗、各节间长度、产量等相关性状。结果表明:在大喇叭口期、抽雄期、灌浆期喷施化控药物后,玉米株高分别降低26.33—42.33、17.33~28.33、16.00~19.00cm;在大喇叭口期、抽雄期、灌浆期和成熟期喷施化控药物后,单株叶面积分别减少456.68—594.18、80.70~279.48、628.15~980.92、257.79—880.42cm2;3种化控药物均可使茎秆增粗.增粗幅度为0.06~0.23cm,不同化控药物之...

Summary: | 以百玉1号为材料,分别在玉米拔节期(10片可见叶)喷施缩节短、恐高、黄金玉配3种化控药物,并在大喇叭171期、抽雄期、灌浆期、成熟期调查玉米株高、单株叶面积、茎粗、各节间长度、产量等相关性状。结果表明:在大喇叭口期、抽雄期、灌浆期喷施化控药物后,玉米株高分别降低26.33—42.33、17.33~28.33、16.00~19.00cm;在大喇叭口期、抽雄期、灌浆期和成熟期喷施化控药物后,单株叶面积分别减少456.68—594.18、80.70~279.48、628.15~980.92、257.79—880.42cm2;3种化控药物均可使茎秆增粗.增粗幅度为0.06~0.23cm,不同化控药物之间存在差异显著;化控药物对玉米产量有较明显影响,可使玉米增产8_30%~11.11%,其中缩节短对玉米的增产效果最好,比清水对照增产11.11%。 |

The results showed that after spraying chemical control drugs, the maize plant height reducing range between 26.33 -42.33 cm in the big bugle stage, the maize plant height reducing range between 17.33-28.33 cm in the anthesis stage, the maize plant height reducing range between 16.00-19.00 cm in the filling stage. In the big bugle stage, anthesis stage, filling stage and autumn stage the leaf area per plant was significantly reduced, reducing range between 456.68-594.18, 80.70- |
