Problems solved by technology

Mixing crop straw with livestock and poultry manure for high-temperature composting and fermentation has become the main way to recycle agricultural waste such as straw and livestock and poultry manure. However, the number and types of straw-degrading microorganisms in pig manure are relatively small. If the two are directly combined Difficult to achieve good results when mixed for composting

Embodiment 1

[0026] This embodiment includes the following steps:

[0027] 1) Preparation of solid microbial agent: inoculate Streptomyces grisea in the straw fermentation medium, ferment and cultivate at 32°C and 150rpm for 3 days, when the concentration of the bacterial solution reaches 10 10 The fermentation was terminated when cfu / mL was reached, mixed with rice flour (1 mm) at a ratio of 1:1 (V / W), and cultured at 32°C for 1 day to obtain a solid inoculum of the bacterium.

[0028] The components of the straw fermentation medium are: straw 10.0g, KNO 3 2.0g, KH 2 PO 4 0.5g, K 2 HPO 4 1.0g, MgSO 4 0.2g, CaCl 2 0.1g, yeast extract 1.0g, distilled water 1.0L, pH 7.0‐7.2. For solid medium, add 18.0g agar to the above components.

[0029] 2) Production of high-temperature compost and temperature measurement of the pile: crush the rice straw to obtain a 5-10cm straw section, then add pig manure and microbial solid agent at 10.0% and 2.0% of the weight of the straw, respectively, and...

Abstract

The invention discloses a high-temperature-resistant actinomycete which can efficiently degrade and convert rice straw and nitrogen in pig manure. The actinomycete disclosed by the invention belongs to streptomyces griseorubens with the preservation number of CGMCC No. 5706. The actinomycete can strongly degrade methyl cellulose in the rice straw, further can quickly convert nitrate nitrogen and organic nitrogen in the pig manure, and tolerates the high temperature of more than 70 DEG C; the actinomycete can be added to the mixed compost of rice straw and pig manure to obviously rise the compost temperature, shorten the fermentation cycle, and improve the quality and the yield of the organic fertilizer; in addition, the organic fertilizer inoculated with the solid bacteria agent can quickly fertilize soil, so as to increase the content of the organic fertilizer, total nitrogen, nitrate nitrogen and ammonium nitrogen, activate the soil enzyme activity, and finally increase the yield of the crop.

Description

technical field [0001] The invention relates to an application in the technical field of agricultural environmental protection and waste utilization, in particular to the application of high temperature resistant Streptomyces in composting agricultural waste. Background technique [0002] Straw is the main product of plant symbiosis and is the most abundant renewable resource in nature. The annual output of crop straws in the world is about 2.9 billion tons, while my country, as a large agricultural country, has an annual output of about 700 million tons of crop straws. In recent years, with the increase of crop yield, the total amount of straw has increased rapidly. In order to catch up with the farming season, rush to sow seeds, and save trouble, the majority of farmers have begun to burn straw in most areas. Large-scale straw burning not only causes great environmental pollution, but also wastes precious resources; at the same time, the large-scale breeding mode of moder...
