Problems solved by technology

Burning straw in farmland will not only destroy the soil, waste resources, but also pollute the environment
The unburned straw is piled up because it cannot be returned to the field in time, which will also cause environmental pollution and reduce the organic matter content of the soil due to the ineffective return of straw to the field.
In recent years, with the widespread use of chemical fertilizers, the output of planting has greatly increased, but the continuous use of chemical fertilizers for many years has also brought serious side effects to the soil: due to the

Embodiment 1

[0018] Example 1. Preparation of Microbial Compound Inoculum

[0019] 1. Transfer culture of strains

[0020] Bacillus subtilis (Bacillus subtilis) ACCC11089 was inoculated into Bacillus subtilis transfer medium with pH 7.0, and cultured at 30°C for 24-48 hours. The composition of Bacillus subtilis ACCC11089 transfer medium is: peptone 5.0g / L, NaCl5.0g / L, beef extract 3.0g / L, agar 15.0g / L, and the rest is water.

[0021] Saccharomyces cerevisiae ACCC20063 was inoculated in Wort Agar (purchased from Shanghai Anpu Scientific Instrument Co., Ltd., catalog number: CFAH-1-05448-0500), and cultured at 30°C for 48-72 hours.

[0022] Aspergillus oryzae ACCC30155 was inoculated into Cha's medium and cultured at 30°C for 48-72 hours. The composition of Cha's medium is: sucrose 30g / L, MgSO 4 ·7H 2 O0.5g / L, FeSO 4 ·4H 2 O0.01g / L, NaNO 3 3g / L, KCl0.5g / L, K 2 HPO 4 1g / L, 15g / L agar, the rest is water.

[0023] Rhodopseudamonas palustris ACCC10649 was inoculated into the following medium with pH...

Embodiment 2

[0036] Example 2. Experiments on preparing straw organic fertilizer by using microbial compound inoculants and promoting rice production increase

[0037] In 2007, an experiment was conducted in Fanchang County, Anhui Province using the microbial compound inoculum prepared in Example 1 to prepare straw organic fertilizer and to increase rice production. Rice fields in this county are generally low- and medium-yield fields. The application of chemical fertilizers over the years has reduced the soil organic matter content year after year, affecting the yield and quality of rice. The plots with uniform soil fertility and medium fertility, the previous crops being rice, and the planting system of "rice-rice" were used as experimental fields, and the rice variety was II You 129.

[0038] The experiment adopts a completely randomized block design, divided into 3 treatments, namely the straw + fungus group, the straw group and the control group; each treatment has 3 plots, each with an a...

Abstract

The invention discloses a microorganism compound microbial inoculum, the strains of which comprise bacillus, soil actinomycetes, microzyme, mildew and photosynthetic bacteria. By using the microbial inoculum for straw fermentation, a result indicates that the microbial inoculum can make straws quickly decay and transfer to organic fertilizer required for the growth of plants, thereby the content of soil humus is increased, and the content of microorganism and trace elements in soil is improved. The physicochemical property of soil is improved, and the capability of water and fertility preserving of soil is increased. The soil permeability can also be improved so as to inhibit the happening of crop pests, and the output and quality of products can be improved. The microbial inoculum has the advantages of convenient use, low cost and obvious effect.

Description

Technical field [0001] The invention relates to a microbial composite bacterial agent and its application. Background technique [0002] Straw is a general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining part of wheat, rice, corn, potato, oilseeds, cotton, sugar cane or other crops after harvesting their seeds. More than half of the products of crop photosynthesis exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource. [0003] my country has a long history of using crop stalks, but due to the low level of agricultural production and low crop yields, the amount of stalks is small. Except for a small amount of stalks used for gaskets, feeding livestock, and partly used for composting, most of the stalks are burned as life fuel. Up. With the development of agricultural production in China, since the 1980s, food production has increased sub...
