Embodiment 1

[0026] In this example, the raw materials for the preparation of organic matter all come from branches of urban maintenance in Binhai New Area, Tianjin.

[0027] In the present embodiment, the preparation method of organic matter is:

[0028] (1) breaking the branches of urban trees into wood powder as a main ingredient, and spraying water to make the wood powder moist;

[0029] (2) Add the following amount of bacterial agent 1 per 10,000 parts of dry wood powder: 20-30 parts, 80-100 parts of soft rot fungi, 80-100 parts of brown rot fungi, 80-100 parts of white rot fungi, and 20 parts of lactic acid bacteria - 25 parts, stacked and fermented indoors for 5-9 days; heat the fermented product above 90 degrees Celsius for 30-60 minutes, or irradiate it under ultraviolet light for 1-3 hours;

[0030] (3) Add bacterial agent 2 per 10,000 parts of dry wood powder at room temperature: 10-25 parts of heat-resistant bacillus group, 10-20 parts of lactic acid bacteria group, 8-15 parts...

Embodiment 2

[0034] In this example, the fermented product obtained in Example 1 is dehydrated. First, the fermented product is absorbed by a water-absorbing agent, and then the absorbed water-absorbing agent and the fermented product are separated by a microfiltration membrane. It should be understood that the dehydration treatment is only to achieve the purpose of dehydrating the fermented product to obtain organic fertilizer, and the present invention is not limited to the dehydration method.

[0035] In the organic fertilizer provided by the invention, the organic matter is derived from branches, and the organic matter accounts for 65%.

[0036] The following is an analysis of the composition of the organic fertilizer provided by the present invention. In this embodiment, the composition of the organic fertilizer obtained by the method for preparing the organic fertilizer of the present invention is analyzed through experimental testing. Specifically, the experimental detection items a...

Embodiment 3

[0040] The organic fertilizer of the present invention of embodiment 1 is used for cultivating Pennisetum and Stipa grandis in Tianjin Binhai New Area. Tianjin Binhai New Area is located in the Bohai Bay, especially in Tanggu and Dagang, where the soil salinization is serious, with high salt content, lack of fertility and low organic matter content.

[0041] Pennisetum cultivation method, comprises the following steps:

[0042] 1) Cultivation site selection: choose saline-alkaline areas for planting under urban broad-leaved forests, with an altitude of 2-5 meters; choose Pennisetum seeds, with a germination rate greater than or equal to 85%; apply 300 kg / mu of landscaping organic fertilizer or urban tree branches before sowing Ferment organic fertilizer 300 kg / mu, avoid trees and plow the soil 50cm deep, and then prepare the land to make the land ready for sowing;

[0043] 2) The sowing time of Pennisetum is in early spring and early March, and the site preparation should be ...

Abstract

The invention discloses an urban tree branch fermentation bacterial agent composition and its fermenting process; the urban tree branch fermentation bacterial agent component comprises bacteria 1, to be specific, Actinobacteria, soft rot fungi, brown rot fungi and white rot fungi, as well as growth inhibition lactic acid bacteria for inhibiting butyric acid bacteria and putrefying bacteria; bacteria 2, to be specific, thermotolerant Bacillus, Lactobacillus, Bifidobacterium, photosynthetic bacteria, saccharomycetes and Actinobacteria; bacteria 3, to be specific, saccharomycetes and photosynthetic bacteria. The fermenting process comprises crushing urban tree branches into powder, and spraying water to wet the powder; adding the bacteria 1, and piling and fermenting indoors for several days; adding the bacteria 2 to prevent the biological growth of aerobic rot acid bacteria and butyric acid bacteria, and fermenting for more than ten days; adding the bacteria 3, and fermenting for several days. By using the urban tree branch fermentation bacterial agent composition and its fermenting process, the problem of treating urban tree branches is solved, the environmental pollution problem is solved, and waste is turned into wealth; a fertilizer prepared by using the fermenting process has high content of nitrogen, phosphorus and potassium and is a good organic fertilizer.

Description

technical field [0001] The invention relates to the technical field of biological fermentation engineering, in particular to a bacterial agent combination for fermentation of urban tree branches and a fermentation process thereof. Background technique [0002] With the rapid development of urban greening, urban green spaces are expanding rapidly, and a large number of urban tree branches are produced. Traditional ideas often believe that tree branches affect health and landscape, so a lot of manpower and funds are spent every year to clean and burn them, which puts a lot of pressure on municipal management and causes great pollution to the environment. [0003] At present, there are three main treatment methods for tree branches in main landscaping concentration areas: sanitary landfill, incineration and composting by traditional methods, but these methods have certain limitations: 1. The landfill operation is simple, but occupies a large area. And it may cause secondary po...
