Experiment on Substrate Ratio of Container Seedling of Dcdbergia cochinchinensi Seedling
In order to ripen the light matrix container seedling technology of Dcdbergia cochinchinensi,the growth of Dcdbergia cochinchinensi under different substrate ratios and different fertilizer was studied for 2 years.The re-sults showed that different matrix ratio had significant effects on the growth of seedling height and ground diame-ter.In addition to the treatment group with a high proportion of yellow soil,most of the seedlings grew poorly.A-mong them,the conventional substrate ratio(100%yellow soil)was used to raise seedlings.The average seedling heights in the first and second years were 52.13 cm and 74.08 cm,respectively,and the average ground diameters were 0.504 cm and 0.787 cm,respectively;while in the treatment group with 60%peat soil,30%Perlite rock,and 10%vermiculite,the average seedling heights in the first and second years were 96.04 cm and 161.23 cm,respec-tively.The average ground diameters are 0.853 cm and 1.421 cm,respectively.In the first year of container seed-ling,the treatment group loaded with compound fertilizer had the best growth,followed by the treatment group loaded with organic fertilizer,and the treatment group loaded with slow-release fertilizer was the worst;in the sec-ond year of container seedling,there were no significant differences among in three containers of the fertilizer-loaded treatments.
