| 摘 要： | 红藤(Daemonorops margaritae Hance)是我国主要商品藤种之一,目前已在广东、海南和福建等省推广人工栽培。红藤苗木培育周期长,从播种到成苗出圃约需一年时间,而壮苗技术是推广人工栽培的关键。为了研究红藤壮苗培育技术,在取得藤苗光照试验和矿质营养试验结果的基础上,安排了苗木施肥试验,以探求红藤苗木最适施肥量,为合理施肥提供科学依据。

| Abstract: | To determine the effects of fertilization upon the growth of rattan seedlings, a fertilizer application experiment on the seedlings of Daemonorops margaritae Hance was carried out at nursery from September 1988 to August 1989. Four levels of fertilizer applications and four replicates were designed for the trial. Analysis of variance and policy-decision of multi-objective were employed to analyze the data obtained from the experiment. The results showed that the seedlings grew better in T3 (1.3g of urea+ 2 g of superphosphate + 2 g of potassium chloride) than in other treatments. In a proper range of fertilizer application, accumulation of major nutrient elements (N, P, K, Ca, Mg) and ash content of seedling was a positive correlation with the increase of fertilizer applications. However, the relatively increasing rate of both ash content and whole nutrient elements of the seedling were decreased sharply with the increase of fertilizer applications. |
