Description

Technical Field

[0001] The invention relates to the technical field of compound fertilizers, in particular to a microbial enzyme multi-nutrient compound fertilizer and a preparation method thereof. Background Art

[0002] Conventional compound fertilizers refer to fertilizers made by mixing a variety of main nutrients (such as nitrogen, phosphorus, and potassium) with trace elements. Their main feature is the comprehensive nutrients that can meet the nutrient needs of crops at different growth stages, helping to improve crop yields and quality. However, crops are often not able to achieve high yields and high quality with only fertilizer nutrient support, because the growth, development, flowering and fruiting of crops also depend on their ability to absorb and utilize nutrients, their resistance to diseases, their adaptability to the soil environment, and so on. If the growth process of crops is not properly intervened, and only the crops themselves are relied upon, it is difficult to ensure that the yield and quality of crops remain at a high level.

[0003] Currently, conventional compound fertilizers can only provide nutrient support for crops, and do not have the ability to regulate, assist, or promote crop growth. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a microbial enzyme multi-nutrient compound fertilizer and a preparation method thereof, wherein the microbial enzyme multi-nutrient compound fertilizer can provide good regulating, assisting, promoting and nutritional effects for crop growth in all stages, and has a very significant effect on increasing crop yields.

[0005] The technical solution adopted by the present invention to solve the technical problem is: a microbial enzyme multi-nutrient compound fertilizer, including a nitrogen, phosphorus and potassium compound fertilizer main body, in which the nitrogen, phosphorus and potassium compound fertilizer main body contains, according to the content per ton:

[0006]

[0007] Furthermore, the nitrogen, phosphorus and potassium in the main body of the nitrogen-phosphorus-potassium compound fertilizer are urea, diammonium phosphate and potassium sulfate respectively.

[0008] Furthermore, the nitrogen-phosphorus-potassium compound fertilizer contains 0.5-5% trace elements by weight, and the trace element raw material is at least one of ferrous sulfate, manganese sulfate, zinc sulfate, copper sulfate, boric acid, and ammonium molybdate.

[0009] Furthermore, the nitrogen-phosphorus-potassium compound fertilizer body also contains, in terms of content per ton:

[0010] Biotin 80-100mg.

[0011] Furthermore, the nitrogen-phosphorus-potassium compound fertilizer body also contains, in terms of content per ton:

[0012] Niacinamide 21000~23000mg.

[0013] Furthermore, the nitrogen-phosphorus-potassium compound fertilizer body also contains, in terms of content per ton:

[0014] Amino acids 30,000-35,000 mg.

[0015] A method for preparing the microbial enzyme multi-nutrient compound fertilizer as described above comprises the following steps:

[0016] (1) preparing nitrogen, phosphorus, potassium and trace element raw materials according to the required ratio to form a nitrogen-phosphorus-potassium compound fertilizer matrix;

[0017] (2) calculating the amount of the components to be added according to the weight of the prepared nitrogen, phosphorus and potassium compound fertilizer matrix;

[0018] (3) putting the nitrogen, phosphorus and potassium compound fertilizer matrix and the components to be added into a pulverizer for pulverization;

[0019] (4) The crushed material is sent to the first mixer via the first conveyor for mixing;

[0020] (5) The materials mixed in the first mixer are then conveyed to the second mixer via the second conveyor for mixing;

[0021] (6) The materials mixed by the second mixer are sent to the cold press granulator via the third conveyor for granulation;

[0022] (7) The prepared granular material is sent to a screening machine via a fourth conveyor for screening to classify the material according to the size of the particles;

[0023] (8) Granular materials of different grades are transported to the storage area for weighing, packaging and testing. Those that pass the test are considered finished products.

[0024] Furthermore, the powdered material screened by the screening machine is collected and then put into the first mixer again to be mixed with the material newly entering the first mixer.

[0025] The beneficial effect of the present invention is that the microbial enzyme multi-nutrient compound fertilizer of the present invention has a very significant effect on increasing the yield of crops. The oligopeptide complex enzyme endophyte extract contained in the compound fertilizer is a mixture of active ingredients such as oligopeptides obtained by fermentation and extraction of plant endophytes. It can be used as a plant growth regulator to promote the growth and development of plants, including increasing photosynthesis, promoting root development and nutrient absorption, etc., thereby improving the growth rate and overall health of plants; at the same time, it can also enhance the disease resistance and adversity adaptability of plants, and improve the antioxidant capacity and disease resistance of plants by inducing plants to produce defensive substances, so that plants can better resist the invasion of external pathogens; in addition, the oligopeptide complex enzyme endophyte extract can also activate the soil, effectively alleviate the problems of soil acidification, hardening, salinization, etc., improve the soil's fertilizer and water retention capacity, and provide a better growth environment for plants. The multiple vitamin nutrients contained in the compound fertilizer have their own positive effects on crops at different growth stages, and are used in combination with the endophyte extract to provide good regulation, assistance, promotion and nutrition for the whole growth stage of crops.

[0037] This comparative example was carried out with reference to Example 2, except that no vitamin B1100 mg and vitamin B2 were added.

[0038] Comparative Example 3

[0039] This comparative example was carried out with reference to Example 2, but differed from Example 2 in that vitamin D3 and vitamin K3 were not added.

[0040] Comparative Example 4

[0041] This comparative example was carried out with reference to Example 2, but differed from Example 2 in that vitamin E and biotin were not added.

[0042] Comparative Example 5

[0043] This comparative example was carried out with reference to Example 2, but differed from Example 2 in that niacinamide was not added.

[0044] Comparative Example 6

[0045] This comparative example was carried out with reference to Example 2, and the difference from Example 2 is that vitamin A and amino acid were not added.

[0046] Comparative Example 7

[0047] This comparative example was carried out with reference to Example 2, and the difference from Example 2 was that oligopeptide complex enzyme endophyte extract, vitamin A, vitamin B1, vitamin B2, vitamin B12, vitamin D3, vitamin E, vitamin K3, biotin, niacinamide, and amino acids were not added.

[0048] The compound fertilizers prepared in Examples 1 to 3 and Comparative Examples 1 to 7 are now tested for increasing crop yield. Rice is used as the test crop, and the rice varieties Shendao No. 47 and Longjing No. 28 are tested respectively. 10 m 2 Rice was planted in the test field, and the compound fertilizers prepared in Examples 1 to 3 and Comparative Examples 1 to 7 were applied respectively. The rice was harvested after 140 days, and the yield was calculated to determine the yield-increasing effect of the fertilizer. The test results are shown in the following table:

[0049] Test record table of the compound fertilizers prepared in Examples 1 to 3 and Comparative Examples 1 to 7 for increasing crop yield

[0050]

[0051] It can be seen from the test results in the above table that the fertilizer prepared in Example 2 has the best yield-increasing effect on the two types of rice; the fertilizer prepared in Comparative Example 1 has the lowest yield-increasing effect because the oligopeptide complex enzyme endophyte extract is not added; the fertilizers prepared in Comparative Examples 2 to 6 have a relatively good yield-increasing effect, but due to the lack of certain material components added in Example 2, the effect is still obviously inferior to the fertilizer prepared in Example 2.

[0052] The above embodiments are only used to explain the present invention, rather than to limit the protection of the rights of the present invention. Any non-substantial changes made on the basis of the essential scheme of the present invention shall fall within the protection scope of the present invention.
