摘要
本研究旨在探讨从不同沼气厂获得的沼液对温室条件下黄瓜植株的生长和矿物质营养的影响。为此，将从两种不同植物（A-B）中获得的不同性质的液态沼气沼渣（LBD）以 5 种不同的剂量（0、20、40、60 和 80 吨/公顷-1）施用到装有 10 公斤土壤的花盆中，并观察处理的效果。研究结果表明，与对照组相比，A5（80 吨/公顷-1）中的沼渣 A 产量增加了 24.6%，B3（40 吨/公顷-1）中的沼渣 B 产量增加了 29%。虽然枸杞多糖有助于增加叶片样本中的氮、钙、锌、铜和锰浓度，但观察到剂量的增加对叶片样本中的氮、钙、锌、铜和锰浓度没有线性影响。人们认为，沼气厂产生的液态沼气废料对水果产量有积极影响，农业实践可以作为处理这些废料的基础，在土壤中使用液态沼气残留物可以消除潜在风险，从而带来显著效益。
The Effects of Liquid Biogas Digestate on Yield and Mineral Nutrition of Cucumber Growing in Greenhouse
This study aimed to investigate the effects of a liquid fraction of digestate obtained from different biogas plants on the growth and mineral nutrition of cucumber plants under greenhouse conditions. For this purpose, Liquid Biogas Digestates (LBD) obtained from two different plants (A-B) with different properties were applied to pots with 10 kg of soil in 5 different doses (0, 20, 40, 60, and 80 t ha-1) and the effects of the treatments were observed. As a result of the research, the highest yields increased 24.6% for digestate A in A5 (80 t ha-1) and 29% for digestate B in B3 (40 t ha-1) compared to control. While LBD contributed to the increase of N, Ca, Zn, Cu, and Mn concentrations in the leaf samples, it was observed that the dose increase did not have a linear effect on N, Ca, Zn, Cu, and Mn concentrations in the leaf samples. It is thought that liquid biogas wastes produced in biogas plants have positive effects on fruit yield, agricultural practices can be taken the basis in the disposal of these wastes and the use of liquid biogas residues in soils by eliminating potential risks can provide significant benefits.
