Effects of Different Nursery Methods and Seeding Levels on the Quality of Rice Seedlings

To explore the differences in the quality indicators of rice seedling nursery under various nursery equipment and seeding levels, experiments were conducted using W-type, S-type, and greenhouse groundbased nursery methods, with seeding levels set at 120 g, 160 g and 200 g per tray. The results indicate that under rainy weather conditions, the seedling quality produced by the S-type equipment was superior to that of the W-type but inferior to ground-based nursery. The optimal seeding levels varied among the different nursery methods,with the best range for W-type and S-type nursery equipment being 160 g/tray to 200 g/tray, while for groundbased nursery, it was 120 g/tray to 160 g/tray. The findings provide theoretical guidance and practical evidence for the cultivation techniques and widespread application of W-type and S-type nursery equipment.
