Abstract:

To improve the quality of seeds, realize the standardization of seeds, and promote the increase of rapeseed yield, the effects of different drug varieties on the growth of rapeseed were explored by pelletizing coating of rapeseed seeds in this study. Among them, the effects of pelletized seed coating agent (NXY-1) and Switzerland suspension seed coating agent (SLS) coated with different drug ratios on the seedling growth of rapeseed were studied using Brassica napus 'Fan-ming No. 1' as the test material. The results showed that the optimal seed mass ratio was 1:300 in the pelletized seed coating agent NXY-1, and the pelletized seed coating agent could promote seed emergence, with the highest dry-to-fresh weight ratio before winter and full flowering stage, and the nitrogen and phosphorus content and potassium content were the highest 21 days after emergence compared with the control, which could effectively increase the contents of chlorophyll and gibberellin, and the effect was better than that of the imported seed coating agent SLS.
