Turba jätkusuutmatu kaevandamine on toonud esile vajaduse leida keskkonnasõbralikumaid alternatiive aianduses kasutatavatele kasvusubstraatidele.
Käesoleva uurimistöö eesmärk oli hinnata, kuidas erinevad vähendatud turbasisaldusega substraadisegud mõjutavad mugulbegoonia (Begonia tuberhybrida) sordi Tubby ʼRedʼ noortaimede kasvu ja õitsemist. Katse viidi läbi Põlva maakonnas, OÜ Kanepi aiandis ning kestis ajavahemikus 14.04.2024 kuni 18.06.2024. Katse käigus mõõdeti 7 substraadisegu taimede kõrgust, laiust, lehtede ja õite arvu. Alternatiivsete substraadisegude tulemusi võrreldi turbapõhise kontrollvariandiga.
Tulemused näitasid, et kõik testitud alternatiivsed substraadisegud andsid võrreldava tulemuse turbaga. Õite arv oli suurim puit 20 variandil, samas kui lehtede arv jäi sarnaseks kontrolliga. Taimede kõrgus ja laius olid suurimad tatar 20 ja Fiberboost segudes, viidates nende sobivusele vegetatiivse kasvu toetamisel. Uuringu põhjal võib järeldada, et nimetatud alternatiivsed substraadid sobivad edukalt mugulbegoonia kasvatamiseks ja võimaldavad turbasisaldust vähendada, mõjutamata taimede kvaliteeti negatiivselt.
The unsustainable extraction of peat has highlighted the need to find more environmentally friendly alternatives to horticultural growing substrates. The aim of this study was to assess how different peat-reduced substrate mixtures affect the growth and flowering of young tuberous begonia (Begonia tuberhybrida ‘Tubby Red’) plants. The experiment was carried out in Põlva County, at the horticultural company OÜ Kanepi, and lasted from April 14 to June 18, 2024. During the experiment, plant height, width, number of leaves, and number of flowers were measured for seven substrate mixtures. The results of the alternative substrate mixtures were compared to a peat-based control variant. The results showed that all tested alternative substrate mixtures produced outcomes comparable to peat. The highest flower count was recorded in the Wood 20 variant, while the number of leaves remained similar to the control. The tallest and widest plants were found in the Buckwheat 20 and FiberBoost mixtures, indicating their suitability for supporting vegetative growth. Based on the study, it can be concluded that these alternative substrates are suitable for the successful cultivation of tuberous begonia and allow for a reduction in peat content without negatively affecting plant quality.
