20.500.12556/DKUM-90669 Kalivost solate kot indikator zrelosti komposta iz izrabljenega gobjega substrata diplomsko delo Lettuce Germination as a Maturity Indicator of a Spent Mushroom Substrate Compost Izrabljen substrat, ki nastane pri gojenju bukovega ostrigarja, lahko predstavlja potencialno organsko gnojilo. V diplomski nalogi je bilo s kalitvenim testom na solati preučeno, kdaj bi bil kompostiran substrat primeren za nadaljnje gnojenje rastlin. Izrabljen gobji substrat (IGS) je bil kompostiran 84 dni. Kompost smo vzorčili vsakih 14 dni in iz vzorcev z deionizirano vodo naredili vodne ekstrakte v razmerju 1:10, s katerimi smo omočili semena solate v petrijevkah. Kaljenje se je sedem dni beležilo na vsakih 24 ur. S pomočjo slik in računalniškega programa se je po sedmih dneh izmerilo dolžine korenin in nadzemnega dela. Izračunani so bili dodatni parametri, kot so skupna kalivost, hitrost kalitve, skupna hitrost kalitve in koeficient hitrosti kalitve. Kalivost solate je bila pri vodnem ekstraktu komposta IGS, ki je bil kompostiran 0, 42, 56, 70 in 84 dni, enaka kot pri deionizirani vodi (82,1–93,2 %). Izračunani indeksi, ki poleg končne, upoštevajo še dinamiko kalitve semen, so bolj natančni in kažejo signifikantno boljše rezultate pri kontroli in najdlje časa kompostiranem kompostu (K: 84). Ekstrakti IGS, kompostiranega 0, 42, 56, 70 in 84 dni, omogočajo kalčkom solate v primerjavi z deionizirano vodo (dolžina rastline 44,4 mm) značilno bolj uspešno rast (dolžina rastline 53,1–59,5 mm). Nekompostiran IGS in IGS kompostiran za dlje kot 42 dni je na podlagi rezultatov kalitvenih testov primeren za uporabo kot gnojilo, najboljše rezultate pa dosežemo, če je kompost zorjen 84 dni. Spent substrate, which is produced during the cultivation of oyster mushrooms can potentially serve as an organic fertilizer. A germination test on lettuce was conducted to determine when the composted substrate would be suitable for further plant fertilization. The spent mushroom substrate (SMS) was composted for 84 days. The compost was sampled every 14 days and water extracts were made using deionized water at a 1:10 ratio. These extracts were then used to moisten lettuce seeds in Petri dishes. The germination process was recorded every 24 hours over a period of seven days. After seven days, the lengths of the roots and the above-ground parts were measured using images and a computer program. Total germination, germination rate, total germination rate, and germination speed coefficient, were also calculated. The germination rate of lettuce in the water extract of SMS composted for 0, 42, 56, 70, and 84 days was the same as in deionized water (82.1–93.2%). The calculated indices, which consider the final germination and the dynamics of seed germination show significantly better results in the control and the longest-composted SMS (K: 84). Extracts of SMS composted for 0, 42, 56, 70, and 84 days allow lettuce seedlings to grow more successfully than in deionized water (plant length 44.4 mm), with a significantly greater length (53.1–59.5 mm). Based on the germination test results, un-composted SMS and SMS composted for more than 42 days are suitable for use as a fertilizer. kompostiranje izrabljen gobji substrat bukov ostrigar kemični parametri kakovosti komposta kalivost solate composting spent mushroom substrate beech oyster chemical parameters of compost quality lettuce germination true true false V.
