摘要

多年生植物通常预先栽培在椰子纤维(椰糠)组成的植被垫上,需要根据天气情况进行灌溉,并定期施速效肥,以尽快达到可销售的状态。在绵羊毛-椰子纤维-植被垫的预栽培过程中,由于绵羊毛纤维的天然含氮量,植被垫中已经含有足够的氮(N),因此在预栽培过程中,如有必要,可以省去额外的液体施肥。在这项研究中,于 2018 年用 16 种多年生植物(8 个品种)预培了 4.5 千克/平方米的绵羊毛-风干物-植被垫。变体 1(V1)在预栽培期间定期施用矿物液肥(总计 8.7 克氮/平方米)。变体 2(V2)在栽培前未施肥。2019 年春,所有预栽培的植被垫都被掀起,铺在用表土准备好的区域上。铺设后没有再施肥。在 2018 年和 2019 年的生长季节,对整体印象、植株高度、多年生植物开花数量和植株覆盖率进行了考察,仅观察到 V1 和 V2 之间存在细微差别。对使用的两个紫菀品种的花朵数量、生物量和氮含量进行了测定。V1 和 V2 在 2018 年存在差异,但在 2019 年没有。经过 4 个月的预栽培,V1 和 V2 的多年生植物覆盖率均达到 50%,这是植被垫可销售的前提条件。V1 和 V2 上多年生植物的总体印象在栽培前和第二年也没有区别。因此,在绵羊毛-风干物-植被垫上对多年生植物进行预栽培时,没有必要进行液体施肥。

Influence of Mineral Liquid Fertilization on the Plant Growth of Perennials on Sheep’s Wool–Coir–Vegetation Mats
Perennials are usually pre-cultivated on vegetation mats consisting of coconut fiber (coir), which require weather-dependent irrigation and regular fertilization with fast-acting fertilizer to achieve a saleable condition as quickly as possible. In the pre-cultivation of sheep’s wool–coir–vegetation mats, nitrogen (N) is already sufficiently contained in the vegetation mats due to the natural nitrogen content of the sheep’s wool fibers, so that additional liquid fertilization during pre-cultivation can be dispensed with if necessary. In this study, sheep’s wool–coir–vegetation mats of 4.5 kg/m2 were pre-cultivated with 16 perennial plants (8 species) in 2018. Variant 1 (V1) received regular fertilization with mineral liquid fertilizer (total 8.7 g N/m2) during pre-cultivation. Variant 2 (V2) was not fertilized during pre-cultivation. In spring 2019, all pre-cultivated vegetation mats were lifted and laid on an area prepared with topsoil. No additional fertilization was applied after laying. The overall impression, plant height, number of flowering perennials, and plant coverage were examined in the 2018 and 2019 growing seasons, with only minor differences observed between V1 and V2. The number of flowers, biomass, and nitrogen content were determined for the two aster species used. There were differences between V1 and V2 in 2018, but not in 2019. The coverage of perennials of 50%, which is the prerequisite for the saleability of the vegetation mats, was already achieved on both V1 and V2 after 4 months of pre-cultivation. The overall impression of the perennials on both V1 and V2 also did not differ during pre-cultivation nor in the following year. Therefore, liquid fertilization is not necessary during the pre-cultivation of perennials on sheep’s wool–coir–vegetation mats.
