Embodiment 1

[0032] The compound materials are tea dregs, cow dung, and straw. The tea dregs and cow dung are taken directly, and the rice straw is taken after being crushed. The mass fraction of 40 was compounded, and a round plastic flower pot with a height of 30 cm and a diameter of 20 cm was used for cultivation. After laying 5cm of material on the bottom layer, inoculate earthworms according to the density of 10g / kg of material. The species of earthworms is Eisenia chinensis, and a layer of straw is laid on the upper layer for shading and moisturizing. After 7 days of inoculation, add a second layer of mixed compound material 10cm to maintain The water content is about 50%, the material digestion reaches about 80%, and the third time add 10cm of material. After 10-15 days, the digestion degree of the material reaches about 90%. Add 5 cm of fresh material for transferring worm species on the surface layer of straw, and transfer the worm species in the surface layer of fresh material to...

Embodiment 2

[0037] The compound materials are tea dregs, cow dung, and straw, among which the tea dregs and cow dung are used directly, and the rice straw is crushed and passed through a 2mm sieve, and the water content of the three is adjusted to 50% respectively (tea dregs: cow dung: straw) The mass fraction of 20:60:20 was compounded, and the plastic transfer boxes with length, width and height of 80cm, 40cm, and 30cm were used for cultivation. After laying 5cm of material on the bottom layer, inoculate earthworms according to the density of 10g / kg of material. The species of earthworms is Eisenia chinensis, and a layer of straw is laid on the upper layer for shading and moisturizing. After 7 days of inoculation, add a second layer of mixed compound material 10cm to maintain The water content is about 50%, the material digestion reaches about 80%, and the material is added for the third time. After 10-15 days, the digestion degree of the material reaches about 90%. Add fresh materials ...

Embodiment 3

[0040]The compound material is mixed with tea dregs, cow dung, and rice straw. The tea dregs and cow dung are used directly, and the rice straw is crushed and passed through a 2mm sieve. ) 20:20:60 mass fraction for compounding, adopting brick culture tanks whose length, width and height are 2m, 1m, and 0.6m respectively, for breeding. The bottom of the breeding tank is leveled with cement, and one end is kept slightly lower, with an inclination angle of about 3-5°, and a water outlet is left at the lower end. The inner side of the water outlet is blocked by gauze to prevent earthworms from escaping. After laying 5cm of material on the bottom layer, inoculate earthworms according to the density of 10g / kg of material. The species of earthworms is Eisenia chinensis, and a layer of straw is placed on the upper layer for shading and moisturizing. After 7 days of inoculation, add the second layer of mixed compound material 10-15cm , maintain the water content of about 50%, the mat...

Abstract

The invention belongs to the field of organic fertilizers and particularly relates to a special organic fertilizer for a tea garden and a preparation method of the special organic fertilizer. Earthworms are utilized to digest and decompose organic wastes subjected to compounding, and then, after most of the earthworms are transferred, the residual earthworms and earthworm feces are applied to the tea garden together as the special organic fertilizer for the tea garden. With compounding of a nutrient ratio of organic materials subjected to compounding and a nutrient demand ratio of tea trees, the special organic fertilizer also contains all varieties of micronutrients needed by growth of the tea trees. The organic fertilizer is low in cost, the raw material sources are wide, the investment cost is low, the preparation process simple, thus the organic fertilizer is suitable for being produced and directly used on site in tea gardens by farmers and tea enterprises. The organic fertilizer is made of pure organic components, and improves the soil physical chemistry, the microorganism attribution and the ecological function of tea garden soil when ensuring supply of effective nutrients including nitrogen, phosphorus, potassium, trace elements and the like.

Description

technical field [0001] The invention belongs to the field of organic fertilizer preparation, and more specifically relates to a special organic fertilizer for tea gardens and a preparation method thereof. Background technique [0002] China is the country of origin of tea, and its tea output and planting area both rank first in the world. In recent years, with the mass production of tea deep-processing products such as instant tea, tea beverages, and tea polyphenols, 200,000-300,000 tons of waste tea dregs can be produced every year. Due to the large output of tea dregs, the current utilization methods are few and the effect is poor, so most of the tea dregs are discarded as garbage, causing serious environmental pollution. Resource utilization is an important idea to solve the problem of tea dregs. [0003] On the one hand, tea dregs come from tea leaves, which are collected from tea trees and contain various nutrients that tea trees absorb from the soil, that is, all kind...
