摘要

评估了不同浓度的沼气浆（BS）对蔬菜种植的影响。将五种浓度的沼渣作为有机肥，通过滴灌种植大白菜（CA），研究沼渣对产量和质量的影响。每个浓度水平重复三次，使用 BS 七次。结果表明，在 T1（BS 25%）处理下，大白菜的平均株高、鲜重、干重、可溶性糖和蛋白质含量均达到最佳水平。其中，单株干重（3.53 克）、可溶性糖含量（0.41%）和可溶性蛋白质含量（0.0039%）分别是 CK 处理的 1.74 倍、1.41 倍和 1.14 倍。此外，施用沼液还改善了土壤的理化性质。施用沼液后，土壤全氮（TN）和可利用磷（AP）含量增加，土壤全氮和可利用磷含量随施用沼液浓度的增加而增加。土壤中的可利用钾（AK）含量随沼气浆浓度的增加而波动。此外，沼液还能适当改善土壤 pH 值。总之，BS 25% 的沼液对 CA 的生长及其质量最为有利，这为沼液作为肥料提供了科学依据。

Effect of drip irrigation with biogas slurry on the yield and quality of Chinese cabbage

Effects of different concentrations of biogas slurry (BS) were evaluated relative to vegetable cultivation. Five concentration levels of BS were used as organic fertilizer to grow Chinese cabbages (CA) by drip irrigation to study the effect of BS on the yield and quality. Each level was replicated three times and BS was used seven times. Results showed that the average plant height, fresh weight, dry weight, and soluble sugars and protein contents of Chinese cabbage under the T1 (BS 25%) treatment were optimal. Among them, dry weight per plant (3.53g), soluble sugar content (0.41%), and soluble protein content (0.0039%) were 1.74 times, 1.41 times, and 1.14 times more than under the CK treatment, respectively. In addition, the application of biogas slurry improved the physical and chemical properties of soil. Soil total nitrogen (TN) and available phosphorus (AP) content increased after the use of biogas slurry, and the soil total nitrogen and available phosphorus content increased with the increase in the concentration of the applied biogas slurry. The available potassium (AK) content of soil fluctuated with the concentration of biogas slurry. In addition, biogas slurry can properly improve soil pH. In conclusion, BS 25% was the best for the growth of CA and its quality, which provided scientific basis for biogas slurry as fertilizer.

期刊介绍： The purpose of BioResources is to promote scientific discourse and to foster scientific developments related to sustainable manufacture involving lignocellulosic or woody biomass resources, including wood and agricultural residues. BioResources will focus on advances in science and technology. Emphasis will be placed on bioproducts, bioenergy, papermaking technology, wood products, new manufacturing materials, composite structures, and chemicals derived from lignocellulosic biomass.
