配方施肥对油茶中幼林营养生长的影响

Effect of Formulate Fertilization on the Vegetative Growth of Young Oil-Tree Forest

施肥是促使林木生长、提高产量和质量的重要措施之一,为了了解肥料对油茶中幼林营养生长的影响规律,进行了配方施肥试验,试验采用正交设计,安排了5因素(N、P、K、B、Zn)、4水平(不同的施肥量)共16个处理.结果表明:N、P、K、B、Zn肥对油茶中幼林的营养生长均有显著影响,其影响按大小顺序为N>P>K>B>Zn,N250P1000K125B20Zn2组合(即每株施N肥250g,P肥1000g,K肥125g,B肥20g,Zn肥2g)效果最好.

Fertilization is one of important measures to promote growth and to increase production and quality of forest. To find out the nutrtiongrowing law of fertilization influence to young oiltea camellia, a formula was made. In the experiment, orthox design was used, five factors(N, P, K, B, Zn), four levels(different fertilization amount) were arranged. Results show that fertilization of N, P, K, B, Zn have conspicuous effects and, the influence sequence was:N>P>K>B>Zn and, the best effect is 250 g, 1 000 g, 125 g, 20 g, 2 g respectively per unit.
