摘要:

沼液是有机物质经发酵后形成的,因其数量大且处理不便成为了环保压力的源头之一。沼液在水稻生产中的利用在缓解了环保压力的同时也提高了水稻产量和土壤质量,是沼液资源化利用的有效途径。沼液中含有丰富的营养元素和微生物分泌物,能够提供水稻所需的各类维生素、生长素、氨基酸等,沼液具备促进水稻生长、防治水稻病虫害的等功能。在浸种、施肥等环节,用沼液部分替代化学药剂可以提升用药效果,降低污染水平,但施用量因各地沼液成分不同而存在差异。本研究对合理利用沼液资源进行了分析总结,发现沼液资源不仅可以提高水稻产量,增加经济效益,还能减少化学污染改良土质,带动农业可持续性发展,对构建农业生态循环平衡具有重要意义。

Abstract:

Biogas slurry is formed by fermentation of organic substances. Because of its large quantity and inconvenient treatment, it has become one of the sources of environmental pressure. The utilization of biogas slurry in rice production not only alleviates the pressure on environmental protection, but also improves rice yield and soil quality. It is an effective way for the resource utilization of biogas slurry. Biogas slurry is rich in nutrient elements and microbial secretions, which can provide all kinds of vitamins, auxin and amino acids required by rice. Biogas slurry has the functions of promoting rice growth and controlling rice diseases and insect pests. In seed soaking and fertilization, the use of biogas slurry instead of chemical agents can improve the drug effect and reduce the pollution level, but the application rate varies according to the composition of biogas slurry in different places. By summarizing and analyzing the rational utilization of biogas slurry resources, it is found that biogas slurry can not only improve rice yield and economic benefits, but also reduce chemical pollution, improve soil quality and drive the sustainable development of agriculture, which is of great significance to build the balance of agricultural ecological cycle.

Key words: biogas slurry, rice, resource utilization, safe utilization, sustainable development
