钼磷酸钾拌种对大豆苗期生长的影响

Effects of Seed Dressing with Potassium Phosphomolybdate on Soybean Growth at Seedling Stage

用钼磷酸钾微肥拌种可显著地促进大豆苗期根系和地上部分生长，拌种后可使大豆地上部分和根系的干物重分别提高２０．３％和 １９．６％，根系活力提高６４．９３％，根硝酸还原酶的活性提高２９．５４％，叶绿素含量提高了２１．３１％，钼磷酸钾微肥对大豆的适宜拌种稀释浓度为１００倍。

Seed dressing with potassium phosphomolybdate can increase the growth of soybean root and shoot at seedling stage significantly. Seed dressing had the dry weights of soybean shoot and root increased by 20.3% and 19.6%, respectively, the root vigor by 64.93%, the NR activity by 29.54%, the chlorophyll content by 31.31%. The suitable dilute concentration of soybean seed dressing with potassium hosphomolybdate is 100 time of dilution.
