Effect of Different Substrates and Slow-Release Fertilizer Loading on Growth of Taxus chinensis var. mairei Container Saplings

Experiments were conducted on three-year container T. chinensis var. mairei sapling cultivation with treatments of four different substrates and four fertilizers. The results showed that treatment of peat: vermiculite = 2:1 and yellow soil: peat: vermiculite = 2:2:1 promoted significantly growth of T. chinensis var. mairei saplings. The latter treatment was recommended for good growth and lower cost. The growth of T. chinensis var. mairei saplings was better with APEX slow-release fertilizer (SRF)(N:P:K=l8:6:12) than that with compound fertilizer N:P:K=15:15:15 (Control). But there was no significant effect on the growth among different quantity of slow-release fertilizer. The experiment resulted that growth of T. chinensis var. mairei saplings was the largest with SRF of 1.5 kg/m3.
