Abstract: Bambusa pervariabilis×Dendrocalamopsis daii was widely planted for green project in southwest of China. Effects of steady-state nutrition and cavity fertilization on shoots, height, diameter at breast height(DBH), etc. were studied under three different treatments. Results demonstrated that sprout date of new bamboo under average fertilization, straight line fertilization, exponential fertilization was 7, 9, 12 days earlier than the date of CK, and number of new shoots under three fertilization treatments were 1.26, 1.43, 1.80 times higher than that of CK. And order of degraded shoots rate of new bamboo under three treatments were average fertilization, straight line fertilization and exponential fertilization. DBH and height of new bamboo under three treatments were 1.09, 1.12, 1.18 and 1.04, 1.06, 1.10 times higher than that of CK. Chlorophyll content of new bamboo leaves under three fertilization treatments were all higher than that of CK. Chlorophyll-a, chlorophyll-b and total chlorophyll content were exponential fertilization> straight line fertilization>average fertilization>CK. Nutrient relative supply rate of exponential fertilization of steady-state nutrition was consistent with relative growth rate of B. pervariabilis × D.daii, which could promote shoots, inhibit degraded shoots rate, increase DBH and height of new bamboo effectively. And nutrition of new bamboo leaf was in better condition with steady-state nutrition.
