摘要：

旱作模式中小麦生产力较低,通过拌种技术可以提高小麦生长质量,促进稳产增产。以郑麦618为供试材料,在沿淮地区旱作种植模式下,进行了自配药剂(A1)、自配药剂(A2)、27%苯醚·咯·噻虫(A3)3组药剂拌种及1组不拌种试验,研究了其对小麦生长及产量的影响。结果表明,与不拌种比较,A1、A2使小麦叶色浓绿,A3无显著差异;A1、A2、A3成熟期时的第1节间长度分别增加-12.3%、-6.2%、10.8%,株高分别增加-1.6、-1.1、1.7 cm;成熟期时A1生物量增加显著,A2、A3则无显著差异;最终产量上,A1、A2、A3分别增产6.6%、1.8%和-2.8%。通过拌种处理可以提高小麦生产力,保障小麦生产安全,本试验中A1表现最优,具有壮苗及增产效应,适合在沿淮地区旱作模式中使用。

Abstract:

Wheat productivity is low in dryland farming systems, and seed dressing with chemicals can improve wheat growth quality and promote stable and increased yields. Using Zhengmai 618 as the test material, three groups of self-prepared formulation (A1), self-prepared formulation (A2), and difenoconazole fludioxonil thiamethoxam 27% FS (A3) were mixed with seeds and one group was not mixed with seeds in the dryland farming systems along the Huaihe River. The effects of these treatments on wheat growth and yield were studied. The results showed that compared with no dressing, A1 and A2 treatments resulted in darker green leaf color in wheat, while A3 treatment showed no significant difference, the length of the first internode at maturity increased by -12.3%, -6.2%, and 10.8% with A1, A2, and A3 treatments, respectively. Plant height increased by -1.6, -1.1, and 1.7 cm with A1, A2, and A3 treatments, respectively. At maturity, A1 significantly increased biomass, while A2 and A3 treatments showed no significant difference. In terms of final yield, A1, A2, and A3 treatments increased by 6.6%, 1.8%, and -2.8%, respectively. Seed dressing with chemicals can improve wheat productivity and ensure wheat production safety. Among the treatments, A1 treatment performed the best, showing strong seedling and yield increasing effects, making it suitable for applying in dryland farming systems along the Huaihe River.
