【摘要】 本试验探讨了酸化水浸种对水稻秧苗素质及产量的影响。试验结果表明，用ｐＨ值为３．５～４．０的酸化水浸种，可明显提高水稻种的发芽率和发芽势，缩短发芽所需浸种天数和破胸时数，秧苗茎基粗壮，根系发达，大大降低了水稻苗期立枯病的发病率。三年本田试验结果表明，用ｐＨ值３．５～４．０的酸化水浸种可在一定范围内提高水稻子粒产量，增产幅度为６％～９％。更多还原

【Abstract】 The effect of different acidic water soaking seeds on rice seedling quality and yield was studied in 3 years the results showed that soaking seeds with PH from 3.5 to 4.0 acidic water raised rice germination percentage and seedling quality,shorten the hours of germination and cut down in cidence of seedling blight at the seedling staye.It was also shown that soaking seed with PH from 3.5 to 4.0 acidic water could increase 6-9% of yield.更多还原
