Method for preparing special bio-organic fertilizer for tea by using plant extract residues
The invention relates to a method for preparing a special bio-organic fertilizer for tea by using plant extract residues. The special bio-organic fertilizer comprises the following raw materials: epimedium extract residues, rhodiola rosea extract residues, pig manure, sheep manure, calcium superphosphate and an EM (effective microorganisms) solution, wherein the materials are added with cellulose and uniformly mixed, and then subjected to piling up, enzymolysis, grinding, fermentation and purification to prepare the fertilizer. The method for preparing the special bio-organic fertilizer for tea by using the plant extract residues has the characteristics as follows: 1, a large quantity of residues generated in production processes of an epimedium extract and a rhodiola rosea extract can be treated stably and effectively, and the fibrinolysis level of follow-up fermentation as well as C and N resource utilization rate can be improved effectively through pre-treatment of cellulose; 2, a production technology can be enlarged to a modernized workshop, odor and worm egg pollution are reduced to the maximum, and the organic content of a product is higher than 50%; and 3, the fertility is lasting. 1. A preparation of the tea plant extract drog method for special biological organic fertilizer, characterized in that It includes the following weight proportions of the raw material: heiba extract drog 20-25%, rhodiola rosea extract drog 23-28%, Pig manure 25-30%, sheep manure 20-28%, calcium superphosphate 3-6%, EM liquid 0.3-0.5%; The preparation method is: (1). Add 3.5-4.5 million cellulase activity unit U, is the proportion of the raw material : = 2000 the cellulase [...] 1, uniformly mixing the added, the piles, enzymolysis, crushing; (2). Fermentation, the fermentation the height of the material (or stacking) should not be more than 1.8m, fermentation temperature is 50-60 the [...] , for summer whole fermentation cycle 12-16 days, winter to 18-25 days; (3). Complete decomposition of organic impurity into the magnetic separation device, content N adjustment, the low-temperature drying the powdery organic fertilizer; (4). Powdery organic fertilizer into the disc granulator, drying. 2. The preparation of the tea plant extract drog method for special biological organic fertilizer according to Claim 1, characterized in that the method for the preparation of (1) piled up in the, enzymolysis, crushing is, Fermentation substrate of the evenly mixed material by the forklift truck to fully mixed to a homogeneous state piles, its moisture content control bit 45-55%, for C/N 23-28, After the pile covering plastic paper thin film, stacking 1.8-2.0 meters, keeping the temperature the 45-50 [...] , enzymolysis time is 12-18h; after hammer type drying after air-drying for the uniform crushing to the granularity 2-4mm. 3. The preparation of the tea plant extract drog method for special biological organic fertilizer according to Claim 1, characterized in that the method for the preparation of (2) to the fermentation is in, Fermentation substrate after fully decomposed, reducing the volume of not less than 32%, water content on 30-38%, the temperature is reduced to 30 the following [...] , to pH 6.0-8.0 basic between the end of the fermentation process. 4. The preparation of the tea plant extract drog method for special biological organic fertilizer according to Claim 1, characterized in that the method for the preparation of (3) to adjust the in content N, low-temperature drying the powdery organic fertilizer is produced, Fermentation substrate of magnetic separation purifiedly adding ammonium sulfate mixed, Low-temperature drying of the organic fertilizer > 50%, moisture content 30-35%, N, P, K total amount > 6.5%. 5. The preparation of the tea plant extract drog method for special biological organic fertilizer according to Claim 1, characterized in that the method for the preparation of (4) in the granulation, drying means, Through 1.5 × 16m a rotary drum dryer a drying and 1.2 × 16m a rotary drum drier for secondary drying, temperature respectively to the 260 and [...] the 150 [...] , special organic fertilizer granular tea produced, then the weighing and packaging, warehousing.
