摘要:

为筛选适合园林花卉栽培的有机基质,以木薯渣、松鳞、蚯蚓土、椰糠等有机废弃物为原料,按体积比混合配制5种基质,通过栽培试验,研究不同配比基质对茉莉生长的影响,同时运用主成分分析法对各基质效果进行综合评价。结果表明,蚯蚓土:泥炭:珍珠岩=6:2:2(T2)和木薯渣:泥炭:珍珠岩=6:2:2(T3)处理在提升茉莉茎粗、分枝数、叶绿素含量、花苞量、生物量积累方面较园土:泥炭:珍珠岩=6:2:2(CK)处理具有明显优势,植株长势良好。与CK相比,T2和T3处理可显著提高茉莉叶片可溶性糖含量,增强茉莉抗寒能力,同时T3可显著增强茉莉的根系活性。综合茉莉12项生长指标,经主成分分析,T3处理综合得分最高,因此T3可作为茉莉栽培基质。

Abstract:

To screen organic culture substrates for garden flowers, cassava residue, wormcast, pine bark, coconut coir were used as raw materials to make 5 substrates by volume ratio. Cultivation experiment was carried out to study the effects of the substrates with different mixing proportions on the growth of Jasminum sambac. The principal component analysis was used to analyze the effects of different substrates. The results indicated that compared with garden soil: peat: perlite=6:2:2 (CK), wormcast: peat: perlite=6:2:2 (T2) and cassava residue: peat: perlite=6:2:2 (T3) had an evident advantage in promoting stem diameter, branch number, chlorophyll content, bud number and biomass of J. sambac, and the plants grew well. T2 and T3 could improve the soluble sugar content to enhance cold tolerance of J. sambac, and T3 increased the root activity of J. sambac significantly. Through principal component analysis of 12 growth indexes, the total score of T3 was the highest, and T3 could be recommended as a substrate formula for J. sambac.

Key words: Jasminum sambac, organic waste, culture substrate, growth index, principal component analysis
