The effects of water and fertilizer on the growth of teak plantation
In order to study the effects of water, fertilizer, site on the growth of teak, according to split plot test method, we carried out an experiment about teak fertilization and water treatment (n=3),including two water treatments (main district) and four N, P, K treatments(deputy district) in the first year after planting. A survey was conducted to the height and diameter of the teak in 1~ 3 a and 13a respectively. The results show that: (1) Fertilization treatment had no significant effect on the growth of the teak in 1~ 3 a and 13 a; (2) Water treatment showed very significant effect on the growth of the teak in 1~ 3 a and 13 a;(3) The replicated test in different sites showed significant effect on the growth of the teak after 2 years;(4) Site and water treatment have a steady influence on the growth of teak, and there is significant interaction relationship between fertilizer treatment and site and as well as fertilizer treatment and water treatment .Therefore, select adapted tree species planted on the suitable site with appropriate fertilizer is a effective way for forest management.
