Abstract

Abstract: The effects of different sowing rate and seedling raising methods on seedling growth, transplanting quality and yield of late season rice Tianyouhuazhan and Yongyou 9 were investigated in field experiment. The results indicated that 90 g/disc of sowing rate, “pot mixture” or “pot mixture plus yellow soil” can raise strong seedling and increase yield of machine-transplated rice.

Key words: late season rice, machine-transplanted rice, sowing rate, seedbed, seedling raising；yield

摘要： 为探讨适宜连作晚稻机插秧标准化育秧技术，以天优华占和甬优9号为材料，采用田间试验方法，研究了5种不同培养土和3个播种量水平对连晚机插秧苗素质、栽插质量和产量的影响。结果表明，不同培养土和播种量培育出的秧苗素质不同，以播种量90 g/盘、“基质”或“黄泥土+基质母剂”作为床土更能培育出适合于机插的高素质秧苗，且实际产量较高。
