preparation example Construction

[0013] The preparation method of the conditioning agent of the present invention is as follows: prepare zeolite, carbon black, and wood vinegar in proportion, mix the wood vinegar into the carbon black, stir evenly, and then pour the mixed carbon black and wood vinegar Into the zeolite, slowly mix and stir evenly.

[0014] The fermentation method of the compost quick-starting moderate fermentation conditioner of the present invention is that in the initial stage of composting, the conditioner is mixed into piles such as livestock and poultry manure, and the weight percentage of the new conditioner mixed in with the compost material is 5-20%, depending on the weight of the material differ by nature. Materials include silkworm excrement, pig manure, cow manure, sheep manure, chicken manure and other livestock and poultry manure.

Embodiment 1

[0017] Compost raw material: silkworm excrement. The specific composition ratio of the conditioner involved in the batching is 85% of zeolite, 13% of carbon black and 2% of wood vinegar. The conditioning agent is uniformly mixed with compost raw material silkworm excrement according to 10% of the total amount of the compost material at the initial stage of composting, and the moisture content is adjusted to 70%. Compost materials are processed by tank fermentation and special mechanical turning. The specific specifications of the pile are 80 centimeters high, 3 meters wide and 50 meters long.

[0018] During the initial 7 days of composting, sampling was performed once a day. In the later stage, samples were taken once on the 9th day, the 11th day, the 13th day, and the 15th day. The specific indicators for sampling analysis are: pH, water content, organic carbon content, total nutrient content of the pile, available nutrient content of the pile, temperature, etc. The expe...

Embodiment 2

[0020] Compost raw material: chicken manure. The ingredients are that the specific composition ratio of the conditioner involved is 74% of zeolite, 20% of carbon black and 6% of wood vinegar. The conditioning agent is uniformly mixed with compost raw material silkworm excrement according to 5% of the total amount of the compost material at the initial stage of composting, and the moisture content is adjusted to 70%. Compost materials are processed by tank fermentation and special mechanical turning. The specific specifications of the pile are 80 centimeters high, 3 meters wide and 50 meters long.

[0021] During the initial 7 days of composting, sampling was performed once a day. In the later stage, samples were taken once on the 9th day, the 11th day, the 13th day, and the 15th day. The specific indicators for sampling analysis are: pH, water content, organic carbon content, total nutrient content of the pile, available nutrient content of the pile, temperature, etc. The ...

Abstract

The invention discloses a novel compost rapid start/proper fermentation conditioner and a use method thereof. The novel conditioner comprises the following components by weigh percent: 70-90% of zeolite, 10-20% of carbon black and 2-6% of pyroligneous. During the composting of livestock manure, 5-20% of conditioner is added in a compost body to exter the effects of rapid start of compost fermentation, proper fermentation and the like; and simultaneously, in the fermentation process, the nitrogen loss can be reduced by 20-30%, the carbon loss is reduced by 10-20%, and the compost period is shortened by 10-20 days.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and relates to a novel conditioner capable of rapid start-up and moderate fermentation of livestock and poultry manure composting and its application method. Background technique [0002] With the large-scale and intensive development of the livestock and poultry breeding industry, the amount of livestock and poultry manure has increased dramatically. According to statistics, the annual production of livestock and poultry manure in the country reaches about 2.5 billion tons. At present, most of these livestock and poultry manures are made into organic fertilizers by composting and fermenting and used in agricultural production. However, these existing composting methods have problems such as slow starting of composting fermentation, long cycle, high manufacturing cost, excessive carbon loss, and low fertilizer efficiency. Simultaneously also lack a kind of simple, effective and commercia...
