| 摘 要： | 采用田间小区试验,研究了施用沼肥和油渣对红枣林土壤硝态氮和红枣产量的影响。结果表明,施用沼肥和油渣对土壤硝态氮含量及红枣产量和品质有显著影响。在红枣生长季节,施用油渣肥和沼肥都能提高土壤剖面的硝态氮含量,显著提高红枣产量和单果质量,增产效果为油渣肥沼肥CK。施用沼肥和油渣肥可提高枣果的维生素C、还原糖和总糖含量,在维生素C和还原糖含量的提高上表现为沼肥油渣肥CK,总糖含量的提高上为油渣肥沼肥CK。

| Abstract: | To investigate the impact of biogas manure and oil residue fertilizer on jujube forest soil NO3- N content and jujube yield, a field experiment was conducted. The results showed that application of biogas manure and oil residue affected the soil NO3- N content, jujube yield and quality significantly. The application of biogas manure and oil residue fertilizer can improve the NO3- N content of soil profile during the growing season of jujube forest, and improve the jujube yield and single fruit mass significantly. The yield increased in the order of oil residue fertilizer>biogas manure>CK. The application of biogas manure and oil residue fertilizer also improved the content of vitamin C, reducing sugar and total sugar content. Vitamin C content and reducing sugar increased in the order of biogas manure>oil residue fertilizer>CK; the effects of the fertilizers on total sugar content increasing are oil residue fertilizer>biogas manure>CK. |
