Abstract

Abstract: In order to improve the growth rate of Camellia nitidissima and realize its early flowering and premature birth, the effects of different base fertilizers, and ratios of nitrogen （N）, phosphorus （P） and potassium （K） topdressing were studied. The results showed that chicken manure and garbage sludge as base fertilizers had obvious promoting effect on the growth of Camellia nitidissima, but pig manure had poor effect. The medium level of N and P and low level of K topdressing had the best effect on the growth of Camellia nitidissima. It was beneficial to the growth of Camellia nitidissima seedlings when 5 kg/plant of chicken manure was used as the base fertilizer at seedling transplanting period, and 29.49 g/plant of urea, 37.43 g/plant of superphosphat and 8.98 g/plant of potassium sulfate was used as topdressing fertilizer in the following growing season.

Key words: Camellia nitidissima, base fertilizers, ratios of nitrogen,phosphorus and potassium topdressing, seedling growth
