不同育秧方式和播种量对水稻秧苗素质的影响

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

为探究不同育秧装备和播种量水平下水稻机插秧育秧秧苗素质各项指标的差异,以W型、S型循环立体苗床和温室地面育秧作为不同育秧方式,设置每盘芽种120、160、200 g共3个播种量水平,展开试验。结果表明,在阴雨天气时,3个播种量水平下,S型装备育出的秧苗素质优于W型,但不及地面育秧;不同育秧方式的最佳播种量也不尽相同,W型和S型育秧装备的最佳播种量范围为芽种160~200 g/盘,而地面育苗方式的最佳播种量范围为芽种120~160 g/盘。本文研究结果为W型和S型循环立体育秧装备技术的推广应用提供了理论指导和实践依据。

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 ground-based 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 ground-based 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.
