不同播量与培养土对机插连晚秧苗素质和产量的影响

Effects of Different Sowing and Nutrition Soil on Seedling Quality and Yield of the Late Season Machine Transplanted Rice

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。

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.
