水稻不同播种量机播机插试验研究

Machine-sowing-and-planting experiment and study of different rice seedling amounts

以早稻品种稻隆香优130,晚稻品种广两优2010为材料,研究了不同播量对水稻机插秧苗素质、机插质量及产量的影响。试验结果表明,不同播种量对机插秧苗素质无明显影响,对机插质量及产量有明显影响。随着播种量增加,机插相同种植密度下,密播秧苗缺蔸率低,机插整齐度高,有效穗和产量增加。

To take earlier rice Longxiangyou 130 and late rice Guangliangyou 2010 as test materials, different sowing amounts＇ impact on rice machine-planting seedling growth, planting quality and yield were studied. The results show that different sowing amounts have no obvious impact on machine-planting seedling growth, but obvious impact on machine-planting quality and yield. Along with the increase of sowing amounts, same machine-planting density, seedling absence-rate will be lower with higher uniformity, effective earing and yield.
