摘要
以萌芽期和4叶期杜梨实生苗接种VA菌根,用不同方法培育梨树菌根苗。结果表明,营养钵砂培较简便、快速,而且成本低;黑塑管半水培和苗床土培成本高和优质菌根苗产量少,且二者培育周期长。苗木菌根化后能显著促进植株生长(如株高、叶面积等)并可在大田干旱条件下提高苗木的移栽成活率。
The VA mycorrhiza seedlings have been cultivated with different methods by inoculating VAM onto the seedlings in the states of germination and four-leaves.It is shown that the Paper tubles sandy cultural method is fast and economic; otherwise, the Plastic tuble semiwater and Seedling bed-soil methods are slow and expensive, and both of them have few good quality mycorrhizal plants. The VAM inoculation can highly increase plant growth (e.g. plant height, leaf area etc.) and the percentage of seedling survivals in the field under the drought condition.
