Fermented Neem Fertilizer, Fermented Neem Enzyme Compost, Fermented Neem Fertilizer Pellet and Method for Producing them

Technical field

[0001] The present invention relates to a fermented neem fertilizer and a method for producing the same.

[0002] The fermented neem fertilizer of the present invention is obtained by fermenting neem or a processed product thereof using a fermentation base containing naturally-occurring carbohydrates, proteins and fats, and improves soil and repels pests, It has excellent effects such as increased permeability and degradability by enzymes, koji molds, natural yeast, lactic acid bacteria, etc. contained in fermented neem fertilizers, making it easier for plants to absorb nutrients in the soil.

Background art

[0003] In the conventional agricultural field, soil damage has been caused by many years of continuous cropping, and in order to avoid this, soil disinfection with pesticides is customary, but because of its strong toxicity, It also has an adverse effect on the environment that goes beyond the human body and crops.

In addition, soil improvement agents using natural ores (Patent Document 1) and repellents and insecticides using natural neem have been proposed (Patent Documents 2 to 4), but sufficient effects have been obtained. It is not done.

Problems to be solved by the invention

[0004] Fermentation neem that has long-lasting crop damage to prevent soil damage caused by pesticides. It has long-lasting effects that prevent adverse effects on the human body and the environment. A fertilizer and a method for producing the same are provided.

Means for solving the problem [0005] The above-described problems can be solved by using the fermented neem fertilizer obtained by fermenting neem or a processed product thereof together with a fermentation base material at 50 ° C or lower according to the present invention.

[0006] That is, the present invention uses (I) a fermented neem fertilizer in which neem or a processed product thereof is fermented at 50 ° C. or less by adding koji mold together with the fermentation base, and (II) a fermentation base that has been previously fermented. (1) fermented neem fertilizer, (III) first step of washing brown rice, steaming, adding koji mold and fermenting with primary sugar, second step of adding natural yeast 'lactic acid bacteria and secondary fermentation, A method for producing a fermented neem fertilizer, characterized in that it is produced by a third step in which neem or a processed product is added and subjected to tertiary fermentation, and a fourth step in which a primary sugar-koji fermentation product is further added and subjected to quaternary fermentation. (IV) The first step of washing brown rice and steaming and fermenting the primary sugar and koji, the second step of adding natural yeast 'lactic acid bacteria and secondary fermentation, and adding the neem or its processed product and tertiary fermentation Add the fermented product obtained in the third step and the first step to add quaternary The fourth stage to be fermented, and natural organic matter, livestock manure, food residue, etc. are added to this.Additionally, saponin is added and mixed to adjust the water content, and then 'fermented' and dried for a certain period of time. A method for producing fermented neem enzyme compost, (V) a first step in which brown rice is washed and steamed and subjected to primary saccharification and fermentation, and a second step in which natural yeast and lactic acid bacteria are added to perform secondary fermentation. 10% by weight of natural organic matter, livestock manure, food residue, etc.

% Addition of -1 粕粕 'Additional saponin, mix and mix for a period of time' Fermentation 'Drying method, fermented neem enzyme compost manufacturing method, (VI) Brown rice is washed and steamed The first step of primary saccharification and fermentation, the second step of adding natural yeast and lactic acid bacteria, and the second fermentation, and filtering the obtained fermented material into solid and liquid components. Livestock manure 'added to a mixture of food residues, etc. with adjusted water content and 10% neem meal by weight', add saponin, mix them, and deposit for a period of time 'fermentation' A method for producing fermented neem fertilizer pellets, characterized by three steps and a fourth step in which the liquid obtained above is further diluted with an appropriate amount of water and kneaded into a pellet forming machine.

[0007] The neem used in the present invention refers to neem (Azadi rachta indica). In the present invention, the leaf, xylem, root, or a pulverized product thereof, neem oil (neem) Oil), neem oil extraction residue (dry neem), etc. You can!

[0008] In the present invention, neem or a processed product thereof is fermented at 50 ° C or lower together with a fermentation substrate. As the fermentation base to be used, natural materials including starch, protein, lipids and the like are used.

For example, rice, wheat, bark, corn, other minor grains, beans such as soybeans, potatoes such as potatoes and sweet potatoes, okara, tea seeds, rapeseed oil cakes, soybean oil cakes, cashew nut shells, etc. . These fermentation substrates can be heated to high temperatures to gelatinize starch, hydrolyzed with acid or hydrolase, or pre-fermented with natural yeast lactic acid bacteria, etc. Alternatively, the processed product can be added and fermented.

[0009] For fermentation, rods such as Aspergillus genus, Rhizopus genus, Mucor genus and the like, which have a function of degrading natural materials including starch, proteins, lipids, etc., are frequently used. Aspergillus 'Soyer' is used. If necessary, natural fermentation mother, lactic acid bacteria, etc. can be used. Fermentation should be performed as much as possible by avoiding over 50 ° C and overheating, cooling, aeration, stirring, etc. to obtain a fermented fertilizer with excellent effectiveness. be able to.

[0010] The fermented product thus obtained is dried and pulverized to form a powdered and pelleted product. In addition, the fermented product can be further fermented at 50 ° C or lower, such as by adding water or neem oil, to obtain a liquid product by removing the solid content. In the fermented neem fertilizer of the present invention, the fermentation base is a component that is easily absorbed by plants by fermentation, and it is contained alive and accumulates in the soil due to the action of microorganisms and enzymes, causing damage. It will break down and absorb the undigested nutrients. In addition, the odor peculiar to neem is alleviated, making it easier to apply, improving the soil, generating pests, and the effect lasts for a long time.

[0011] These can be used directly or diluted and mixed with general fertilizer, livestock manure, food residue, compost, etc. that can be applied to soil. Usually, 10 to 500 kg, preferably 50 to: LOOkg is used per 10 ares. LOOkg is used for liquid products, and 1 to 20 liters for liquid products, preferably 1 to 8 liters.
