主 题：Metasequoia glyptostroboides seedling nitrogen exponential fertilization plant growth biomass nutrient supply
摘 要：Metasequoia glyptostroboides(***)is a unique plant species related to relic flora in *** plays a positive role in afforestation and its long-term protection with high paleoclimate research ***,due to the nutrients-supply deficiency,it is a big challenge to cultivate the high-quality seedlings of ****** this study,a pot experiment in a greenhouse environment was carried out to identify the effect of N-exponential fertilization on the growth and nutrient distribution of *** *** ***tostroboides rooted seedlings with 12-month growth were *** N fertilizer levels with conventional fertilization(CF:5.0 g seedling^(−1)),exponential fertilization including EF1,EF2,EF3 and EF4 were *** relevant growth indexes were measured after 210-day *** results indicated that non-significant differences in seedlings’height and ground diameter were found among the above treatments(P0.05);At the same time,N-exponential fertilization promoted the ***’s biomass in different organs(P0.05),with the maximum total biomass under EF3 *** N accumulation in root and stem of the N-exponential fertilization treatments were increased in to some extent(P0.05).The maximum N accumulation was also found under EF3 ***,steady-state nutrition and superior growth performance of ***boides could be obtained by N-exponential fertilization of 5.0 g cutting^(−1).
