甘薯(红苕)提早扦插,已经是甘薯栽培上较为肯定的增产措施。为使露地育苗之苕苗能快速生长,达到提早栽插目的,我们先后进行了露地苗床上使用不同浓度土制赤霉素催苗。经观察测定结果,在不同程度上均表现出刺激苕苗迅速生长效应,起到提早栽插作用。现将初步试验结果简报如下,以供生产应用参考。 Sweet potato (red crab) early cuttings, sweet potato cultivation is more sure to increase production measures. In order to make the nursery shoots in the open field grow rapidly and achieve the purpose of early planted planting, we have carried out germination gibberellin seedlings of different concentrations on the open field seedbed. The observed results, to varying degrees, have shown to stimulate the rapid growth effect of seedlings, played the role of early planting. Now the preliminary test results are summarized below, for production and application of reference.
