背景:这项研究的目的是通过试验各种无土培养基(CMs)和开心果木醋(WV)的应用来提高温室中生长的黄瓜幼苗的质量。实验设置设计为随机完整区组设计(RCBD)中的阶乘实验,在具有三个重复的温室条件下,以评估不同培养基(CMs)和开心果木醋(WV)浓度对黄瓜幼苗生长的影响。黄瓜种子种植在三个CM中:可可泥炭-泥炭苔藓,可可泥炭-维米康波,以75:25的体积比混合的椰枣堆肥-蠕虫堆肥。然后用浓度为0,0.5和1%的开心果WV处理,在第三片叶子出现后的灌溉过程中应用了四次。
结果:研究表明,在枣树堆肥-蠕虫堆肥CM中用0.5%WV处理幼苗可显着提高各种生长参数。具体来说,它导致了90%的新鲜射击质量增加,枝干质量增加59%,根新鲜质量增加11%,根干重增加36%,芽长度增加65%,叶面积增加62%,茎直径增加25%,相对含水量(RWC)增加41%,膜稳定性指数(MSI)提高6%,与在可可泥炭-泥炭苔藓CM中生长的未经处理的幼苗相比。此外,叶绿素a,B,总叶绿素,类胡萝卜素水平分别是2.3、2.7、2.6和2.7倍,分别,在用0.5%WV处理并在枣树堆肥-蠕虫堆肥CM中生长的幼苗中,与用相同浓度的WV处理但在可可泥炭-泥炭苔藓CM中生长的那些相比。此外,Fv/Fm比增加了52%。当用椰枣堆肥-蠕虫堆肥CM和1%WV增强植物营养时,与在可可泥炭-泥炭苔藓CM中生长并用0.5%WV处理的幼苗相比,生长素含量增加了130%。
结论:该研究表明,使用0.5%WV与椰枣堆肥-蠕虫堆肥CM结合使用显着改善了黄瓜幼苗的质量,优于其他治疗组合。
BACKGROUND: The goal of this research is to enhance the quality of cucumber seedlings grown in greenhouses by experimenting with various soilless culture mediums (CMs) and the application of pistachio wood vinegar (WV). The experimental setup was designed as a factorial experiment within a randomized complete block design (RCBD), in greenhouse conditions featuring three replications to assess the effects of different culture media (CMs) and concentrations of pistachio wood vinegar (WV) on cucumber seedling growth. Cucumber seeds were planted in three CMs: coco peat-peat moss, coco peat-vermicompost, and date palm compost-vermicompost mixed in a 75:25 volume-to-volume ratio. These were then treated with pistachio WV at concentrations of 0, 0.5, and 1%, applied four times during irrigation following the emergence of the third leaf.
RESULTS: The study revealed that treating seedlings with 0.5% WV in the date palm compost-vermicompost CM significantly enhanced various growth parameters. Specifically, it resulted in a 90% increase in shoot fresh mass, a 59% increase in shoot dry mass, an 11% increase in root fresh mass, a 36% increase in root dry mass, a 65% increase in shoot length, a 62% increase in leaf area, a 25% increase in stem diameter, a 41% increase in relative water content (RWC), and a 6% improvement in membrane stability index (MSI), all in comparison to untreated seedlings grown in coco peat-peat moss CM. Furthermore, chlorophyll a, b, total chlorophyll, and carotenoid levels were 2.3, 2.7, 2.6, and 2.7 times higher, respectively, in seedlings treated with 0.5% WV and grown in the date palm compost-vermicompost CM, compared to those treated with the same concentration of WV but grown in coco peat-peat moss CM. Additionally, the Fv/Fm ratio saw a 52% increase. When plant nutrition was enhanced with the date palm compost-vermicompost CM and 1% WV, auxin content rose by 130% compared to seedlings grown in coco peat-peat moss CM and treated with 0.5% WV.
CONCLUSIONS: The study demonstrates that using 0.5% WV in conjunction with date palm compost-vermicompost CM significantly betters the quality of cucumber seedlings, outperforming other treatment combinations.
