不同基肥和氮、磷、钾配比追肥对金花茶幼苗生长的影响

Effects of different base fertilizers,and ratios of nitrogen,phosphorus and potassiumtopdressing on the growth of Camellia nitidissima seedlings

为了提高金花茶(Camellia nitidissima)的生长速率,实现其早花早产,研究了不同基肥和氮、磷、钾配比追肥对金花茶幼苗生长的影响。结果表明,以鸡粪和垃圾泥作基肥对金花茶的生长具有明显的促进作用,而猪粪的效果较差;追肥处理以施中等水平的N和P、低水平的K对金花茶的生长效果最好。金花茶幼苗移栽时施5 kg/株的鸡粪作基肥,在随后的一个生长季节施尿素29.49 g/株、过磷酸钙37.43 g/株、硫酸钾8.98 g/株有利于促进其生长。

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 niti⁃dissima.It was beneficial to the growth of Camellia nitidissima seedlings when 5 kg/plant of chicken manure was used as the base fertil⁃izer 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.
