摘要: 为探明除草剂与生物刺激素混合使用对玉米生长、除草效果的影响,将35%硝·烟·莠去津和不同用量的生物刺激素进行组合,开展玉米田间除草试验。结果表明,单独施用35%硝·烟·莠去津,田间杂草防治效果达95%以上。较清水对照,单独施用35%硝·烟·莠去津处理10 d后的玉米株高、茎粗、叶面积、叶绿素相对含量(SPAD值)均提高;与单独施用35%硝·烟·莠去津相比,优翠露与35%硝·烟·莠去津组合施用,杂草防治效果无显著差异,喷施10 d后,玉米株高、茎粗、叶面积、SPAD值均提高,产量提高6.9%~11.0%。总的来看,喷施优翠露3 000 mL·hm-2+35%硝·烟·莠去津2 550 mL·hm-2处理可促进玉米生长及提高产量,可在生产上推广应用。

Abstract:

To investigate the effects of combining herbicides and biostimulants on maize growth and weed control efficacy, a field experiment was conducted using 35% nicosulfuron·mesotrione·atrazine mixed with varying doses of biostimulants. The results showed that the standalone application of 35% nicosulfuron·mesotrione·atrazine achieved over 95% weed control efficacy. Compared with the water control, the standalone herbicide treatment significantly increased maize plant height, stem diameter, leaf area, and relative chlorophyll content (SPAD) on values 10 days after application. When the biostimulant Youcuilu was combined with 35% nicosulfuron·mesotrione·atrazine, there was no significant difference in weed control efficacy compared to the standalone herbicide treatment. However, on 10 days after spraying, the combined treatment further enhanced plant height, stem diameter, leaf area, SPAD values, and increased yield by 6.9%-11.0%. Overall, the treatment of Youcuilu 3 000 mL·hm-2 + 35% nicosulfuron·mesotrione·atrazine 2 550 mL·hm-2 promoted maize growth and improved yield, demonstrating potential for practical agricultural application.
