摘要: |
【目的】探究在番茄不同生育时期施加沼液对其产生的影响,优化西北地区温室番茄水/沼液一体化灌溉模式。【方法】采用沼液浓度1:4的溶液(沼液:水,体积比)分别在番茄的苗期(P1)、开花结果期(P2)、果实膨大期(P3)和果实成熟期(P4)施用,并设置了不施用沼液的对照处理(CT)。【结果】不同沼液处理均能促进番茄的生长以及干物质、产量和品质的形成;P2处理最有利于番茄叶面积的生长,P3处理次之,分别较CT增加了48.32%和36.89%;P3处理更有利于果实干物质积累,较CT增加了47.18%;可溶性糖、可滴定酸、糖酸比和硬度以P3处理最优,维生素C和可溶性固形物以P2处理最优;【结论】基于TOPSIS法的综合效益评价结果表明番茄的果实膨大期为产量品质形成的关键阶段,应当适度增加水肥的投入。本研究可为水/沼液一体灌溉模式下番茄全生育期灌溉量的科学合理分配提供参考。 |

Abstract: |
【Objective】In order to explore the effects of applying biogas slurry to tomatoes at different growth periods, optimize the integrated water and fertilizer supply technology for greenhouse tomatoes in northwest China, and provide technical support for the production of high-quality tomatoes in this area. 【Method】The study applied the biogas slurry solution (the volume ratio of biogas slurry to water is 1/4) at different tomato growth periods by greenhouse experiment, and the results are compared with that of no biogas slurry applied (CT). The growth period is divided as the seedling period (labelled as P1), blooming and fruiting period (P2), fruit expansion period (P3) and at the fruit ripening period (P4). 【Result】The results show that all treatments with biogas slurry application can promote the growth, the dry substance, the production and the quality of tomato plants effectively. The most beneficial treatment to the growth of tomato leaf area is P2, followed by the treatment P3, which increased by 48.32% and 36.89% respectively compared to CT. the treatment P3 accumulates more than 47.18% of the fruit dry substance when compared with CT treatment. Moreover, the soluble sugar, titratable acid, sugar-to-acid ratio and hardness are improved most in the treatment P3, while the vitamin C and soluble solids are the best in the treatment P2. 【Conclusion】Based on the comprehensive benefit evaluation of the TOPSIS method, which is a combination of analytical hierarchy process (AHP) and entropy method, the results show that the fruit expansion period of tomato is the key period for the formation of production and quality, in which the input of water and fertilizer moderately can improve the agricultural income. The research is helpful to the scientific and reasonable application of water and fertilizer during the whole growth period of tomato under the integrated water and fertilizer irrigation mode. |
