preparation example Construction

[0021] (1) Preparation of bacterial suspension

[0022] The single Li-2013 colony grown on the plate streaked and separated into the seed culture medium, 100r / min, 40 ℃ after 12 hours of culture, 1mL culture broth was centrifuged, washed twice with saline, and resuspended with 9mL physiological In salt water.

[0023] (2) Combined mutagenesis of ultraviolet light-lithium chloride-diethyl sulfate

[0024] Place the bacterial suspension in a sterile plate, stir and irradiate it under a UV lamp with a distance of 30cm and a power of 15w for 100s. The irradiated bacterial solution was applied to a lithium chloride plate after gradient dilution, and the plate was diluted with the bacterial solution without ultraviolet irradiation as a control. Wrap the above-mentioned uniformly coated plate with black cloth or newspaper, and incubate at 40°C for 48 hours. On the plate with colony growth, the one with the largest ratio of hydrolysis circle to colony diameter is selected and stored on the...

Embodiment 1

[0059] Example 1 A high-efficiency composite biological fertilizer, which is composed of Aspergillus niger culture, Bacillus megaterium phosphate, and Bacillus subtilis inoculants. The weight group of the high-efficiency composite biological fertilizer becomes: 40 parts of Aspergillus niger culture, Bacillus megaspore phosphate 8 parts of Bacillus and 20 parts of Bacillus subtilis;

[0060] The high-efficiency compound biological fertilizer is prepared by the following method:

[0061] Bacteria culture preparation:

[0062] Preparation of Bacillus subtilis agent culture: transfer and cultivate Bacillus subtilis from the inclined plane, and transfer the seed liquid after stepwise expansion into the fermentation tank. After the fermentation is completed, the fermentation liquid is vacuum-concentrated to 50% of the original volume under low temperature and negative pressure to obtain the bacteria Concentrate. Add carrier: add the mixed carrier to the concentrated solution and mix even...

Abstract

The invention discloses an efficient compound biofertilizer. The efficient compound biofertilizer is composed of an aspergillus niger culture, a phosphate solubilizing bacillus megaterium preparation and a bacillus subtilis preparation. Experiment results prove that the efficient compound biofertilizer can be used for increasing the grain yield by 8-30%, increasing the vegetable yield by 10-40% and improving the quality and flavor of vegetables and grains. The dosage of the fertilizer applied in each mu of land is 50-100g. The efficient compound biofertilizer is one of efficient compound biofertilizers with lower dosages at home and abroad at present.

Description

Technical field: [0001] The invention relates to fertilizers in agricultural technology, in particular to a new type of high-efficiency compound biological fertilizer. Background technique: [0002] Most of the existing biological fertilizers are unitary biological fertilizers. Such as: nitrogen-fixing bacterial fertilizer, which is mainly composed of bacteria and fungi with nitrogen fixation; another example: phosphorus bacteria, whose function is to decompose organic phosphorus in the soil and turn it into phosphorus that is easily absorbed by plants; another example: bacteria, Its function is to decompose potassium compounds in the soil and make it into quick-acting potassium that can be absorbed and utilized by plants. These fertilizers can play their own roles when used alone, and partially meet the needs of plants for the three elements of nitrogen, phosphorus and potassium. They will not produce soil compaction caused by long-term use of chemical fertilizers. But its di...
