| Abstract: In order to promote the development of seed and seedling industry of the Nanchang Sechium edule , and screen out suitable medium for cultivating strong seedling, the local commonly planted cultivar Nanchang Sechium edule was selected as the object of seedling, and three groups of matrix formula (peat∶vermiculite∶organic fertilizer = 3∶1∶1, peat∶perlite∶organic fertilizer = 3∶1∶1 and peat∶vermiculite∶organic fertilizer = 7∶2∶1, mass ratio) were independently prepared, products sold in the market by nursery substrate was taken for comparison. Through the contrast of the indicators, the results was concluded that seedlings cultivated under formula 1 (peat∶vermiculite∶organic fertilizer = 3∶1∶1) growed well and had better seedling growth, with the thick green leaves, tender, white and dense roots. The matrix and root wrapped tightly, the matrix and root system were tightly wound and the root lump was complete, which conformed to the standard of strong seedling. It was suitable for cultivating seedlings of the Nanchang Sechium edule. |
