榆树盆景无土栽培基质筛选研究

Soilless Cultivation Substrates Selective Study of Elm Bonsai

[目的]利用榆树盆景进行无土栽培基质筛选试验,以解决榆树盆景的无土栽培技术。[方法]无土栽培基质采用5种不同处理,对照(CK)为常规土壤栽培盆景,每个处理10盆,3个重复,测量新枝生长量、叶色、总体生长状况。[结果]第1年各栽培基质处理对榆树盆景生长影响不大,第2年各栽培基质处理对榆树盆景生长影响很大。[结论]处理1(泥炭∶沙=6∶4)、处理2(泥炭∶珍珠岩=6∶4)、处理3(泥炭∶沙∶珍珠岩=6∶2∶2)均可替代常规的土培方式,用于榆树盆景的栽培。

[Objective] The elm bonsai was used in selective test of soilless cultivation substrates,to solve the elm bonsai of soilless cultivation technique. [Method]5 kinds of different treatment were used for soilless cultivation substrates,with the conventional soil cultivation as the control（ CK）,and each treatment had 10 pots,3 repeats,the shoot growth amount,leaf color and total growth status were measured.[Result]The soilless cultivation substrates treatment had no influence on the first year growth of elm bonsai,while had the great effects on the second years growth of elm bonsai. [Conclusion] The treatment 1（ peat∶ sand = 6 ∶4）,treatment 2（ peat∶ perlite = 6 ∶ 4）,and treatment 3（ peat∶ sand∶ perlite = 6∶ 2∶ 2） could replace the conventional soil culture for the cultivation of elm bonsai.
