Seedling raising substrate developed from aerobic fermentation product of vegetable residue source agricultural waste and use thereof

Abstract

The invention provides a seedling raising substrate developed from aerobic fermentation product of vegetable residue source agricultural waste and use thereof. The seedling raising substrate is prepared from the following raw materials: an aerobic fermentation product of vegetable residue source agricultural waste, turfy soil, vermiculite and perlite. A method comprises the following steps: uniformly mixing a vegetable residue and auxiliary materials according to a certain C / N ratio, carrying out aerobic fermentation by adopting an airflow membrane fermentation mode, uniformly mixing the materials subjected to aerobic fermentation and decomposition with turfy soil, vermiculite and perlite according to a certain ratio, carrying out seedling culture, and observing a seedling culture effect. A formula of the seedling raising substrate is that a ratio of a fermentation product, turfy soil, vermiculite and perlite is 25:5:10:10. Compared with a commercially available substrate, the formula can achieve a similar seedling culture effect in cucumber seedling culture and a better seedling culture effect than that of the commercially available substrate in tomato seedling culture.

Description

technical field [0001] The invention belongs to the field of seedling raising, and provides a seedling raising substrate developed from aerobic fermentation products of agricultural waste from vegetable sources and an application thereof. Background technique [0002] Tail vegetables, that is, wastes from the planting and processing of leafy vegetables, solanaceous fruits and other vegetables. As the output of vegetables in our country increases year by year, the output of tail vegetables is also increasing. The annual production of tail vegetables in my country is as high as 300 million tons. Random dumping, landfilling, accumulation, etc. will not only waste precious organic matter and nutrient resources, but also cause damage to the environment. The environment has caused a lot of pollution, so the resource utilization of tail vegetables is an important way to ensure the sustainable development of agriculture and improve the quality of vegetable land. The composting of th...

Problems solved by technology

Traditional composting methods include strip-stack fermentation, turning-and-throwing fermentation, etc. These fermentation methods require a certain amount of investment in fixed assets, require a lot of space, and cannot solve the problem of odor in the composting field, and the composting efficiency is low, while the airflow membrane Fermentation technology overcomes the above-mentioned shortcomings of the traditional composting process, and has the advantages of low cost of composting and less demand for odor-free composting sites. In addition, during the fermentation process of the air-flow membrane, the compost is covered with an air-filtering membrane, which effectively reduces the composting process. The volatilization of ammonia nitrogen in the medium reduces the loss of nutrients in the fertilizer, which can improve the composting efficiency and fertilizer quality

However, there are no relevant reports on air-flow membrane fermentation for tail vegetable raw materials with high water content, and the seedling cultivation substrate developed by this fermentation product.
