Problems solved by technology

However, there are also deficiencies. Many basic and applied research on microbial fertilizers only focus on analysis of reasons for increasing production, isolation of strains and field tests. Destroying the environment and unstable fertilizer effects, these problems have restricted the further development of microbial fertilizers

Embodiment 1

[0040] The decomposing of embodiment 1 organic fertilizer

[0041] (1) 500 kg of corn stalks and corncobs are pulverized into 50-60 mesh powder;

[0042] (2) Spread a layer of sludge with a thickness of 20cm on the ventilation ditch of the accumulation yard as a bottom pad for absorbing infiltrating fertilizer;

[0043] (3) Put pig manure and decomposing agent (effective number of viable bacteria ≥ 2.0×10 10cfu / g enzyme bacteria, add 1-3kg per ton), crop straw powder, attapulgite, mix well, pile up layer by layer, make sure, and sprinkle manure and water on each layer, and then sprinkle evenly A small amount of lime and phosphate rock powder are added, and the thickness of each layer is generally 15-25cm until it reaches a height of 1.2-1.5m. The upper layer should be thin, and the middle and lower layers should be slightly thicker. The maximum water holding capacity of the compost material is 60-75%, the carbon-nitrogen ratio is controlled at 25:1, and the pH value is contr...

Embodiment 2

[0046] The preparation of embodiment 2 compound microbial fertilizers

[0047] Prepare 100kg of compound microbial fertilizers according to the following weight ratio: 12 parts of inorganic fertilizers, 35 parts of organic fertilizers, 8 parts of medium and trace elements, 20 parts of chelating agents, 5 parts of microbial bacterial agents, and 20 parts of fillers.

[0048] The composition ratio of the inorganic fertilizer is urea 4: ammonium sulfate 1: diammonium phosphate 2.5: calcium magnesium phosphate fertilizer 2: potassium sulfate 2.5;

[0049] The organic fertilizer is decomposed from pig manure, corn stalks, wheat stalks, and cotton stalks, and the mass ratio of each component is 9:1:1:1;

[0050] The composition ratio of the trace element raw materials is ammonium molybdate 1: borax 2: copper sulfate 2: zinc sulfate 3;

[0051] Described chelating agent is fulvic acid, needs to carry out necessary ammonification treatment according to the routine technique in this f...

Embodiment 3

[0058] The preparation of embodiment 3 compound microbial fertilizers

[0059] Prepare 100kg compound microbial fertilizer according to following weight ratio: 10 parts of inorganic fertilizers, 32 parts of organic fertilizers, 10 parts of medium and trace elements, 25 parts of chelating agents, 6 parts of microbial bacterial agents, 17 parts of fillers.

[0060] The composition ratio of the inorganic fertilizer is urea 3: diammonium phosphate 1.5: ammonium bicarbonate 1.5: calcium magnesium phosphate fertilizer 2: potassium sulfate 2;

[0061] The composition ratio of the organic fertilizer is obtained from decomposing pig manure, corn stalks and wheat stalks, and the mass ratio of each component is 9:2:1;

[0062] The composition ratio of the medium and trace element raw materials is ammonium molybdate 1: borax 2.5: magnesium sulfate 3.5: ferrous sulfate 3;

[0063] Described chelating agent is fulvic acid, needs to carry out necessary ammonification treatment according to ...

Abstract

The invention relates to a compound microbial fertilizer and a method for producing the compound microbial fertilizer. The compound microbial fertilizer comprises the following components by weight: 5-15 parts of inorganic fertilizer, 20-45 parts of organic fertilizer, 4-10 parts of medium trace elements, 10-25 parts of chelating agent and 1-8 parts of microbial agent. The compound microbial fertilizer is rich in organic matters, efficient chelating agent and functional micro-organisms and can improve the physical and chemical properties of soil, increase the utilization rate of the medium trace elements, keep the soil nutrient balance, restrain the occurrence of soil-borne diseases and enhance the crop yield and quality.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a compound microbial fertilizer and a preparation method thereof. Background technique [0002] Over the years, the application of chemical fertilizers has played a key role in increasing agricultural production and income. However, due to the long-term application of chemical fertilizers, the utilization rate of fertilizers has decreased, and the supply of organic fertilizers has been insufficient, resulting in varying degrees of damage to the farmland ecological environment, soil physical and chemical properties, and soil microbial flora, affecting the quality of agricultural products to a certain extent. The current status of soil resources in our country urgently needs to supplement soil organic matter through artificial measures to ensure the improvement of agricultural planting level and crop product quality. This has brought good development opportunities...
