摘　　要：采用盆栽试验比较了施入不同物质组成的抗逆配方,对主要造林树种侧柏和油松成活率与生长的影响。结果表明,不同抗逆配方对侧柏和油松生长均具有显著的促进作用,其中配方A13、A22、C3和C5在侧柏苗木成活率、生长量等方面的促进作用均高于其他配方;配方B5在提高油松苗木成活率、生长量和地径等方面的作用普遍优于其他配方。初步说明上述配方可应用于林业生产中。In order to strengthen the growth potential ,we devised 22 combinations for improving antidrought ability of Platycladus orientalis and Pinus tabulaeformis. The pot experiment was adopted to study the effect of the different combination. Results showed that all the combinations could significantly promote Platycladus orientalis and Pinus tabulaeformis growth. Of them, A13, A22, C3 and C5 could more substantially improve the survived rate, and growth of Platycladus orientalis than others did, however, with regard to Pinus tabulaeformis, B5 could improve the survived rate, cauline and high growth of Pinus tabulae formis seedling than other combinations. The research suggested that the selected combinations could be applied in resistance drought afforestation.
