摘要
于2013年4月在通辽农科院试验基地,以麦巨金为材料,研究不同喷施时期对春小麦茎秆基部形态特征、抗折力和倒伏系数及产量的影响。结果表明:于拔节期、孕穗期、灌浆期分别喷施麦巨金可明显降低株高、缩短基部节间长度,显著提高茎秆抗折力,增强其抗倒伏能力,并提高单位面积产量。
Taking Maijujin as test objects,a field experiment was conducted in the experimental farm of Tongliao Academy of Agricultural Sciences in April 2013.The effects of different spraying time on the basal stemmor phological characteristics ,snapping-resistance ,lodging index and grain yield were studied.The results showed that spraying Maijujin at jointing stage ,booting stage and grain filling stage could decrease the plant height and the basal internodes length,increase the snapping-resistance and lodging-resistant index, strengthen the lodging-resistance, and improve grain yield obvionsly.
