| 早期播种时调酸和消毒及二者的互作对苗质的影响较强,随播期推迟其影响减弱,从回归分析中可以找出北京地区不同播期的调酸与消毒的最佳值。苗期有效积温和盘土 pH 呈正相关。直接向盘土喷酸化水代替常规调酸的简化调酸技术证明是可行的。 |

| Abstract: |
| During the early sowing,the seedling height and the dry weight of one hundred seedlings with the plate earth of pH 4.10 were the highest and those with the plate earth of pH 4.10-5.38 were beneficial to the root growth.The sterilizing effect with 1000 times solution of was rather good.The compleme- ntary effects of sowing date,adjusting acidity,sterilizing and sowing date with adjusting acidity reached very obvious level.Early sowing by adjusting acidity and sterilizing and the eomplementation of both had a... |
