Embodiment 1

[0027] Take 1 kg of straw segments cut into 3-5 cm length and 5 kg of pig manure, put them into a heat-insulated box-type reactor made of 12 L foam and install a plexiglass ventilation pipe at the bottom, add 0.25 kg of glass with a particle size of 0.5-2 cm Pumice, fully mixed, adjust the moisture content of the mixed material to 70%, use a vacuum pump with timer control to ventilate the pile, the ventilation rate is controlled by a glass rotor gas flowmeter, and the ventilation rate is set at 0.03m 3 ·(h·kg) -1 During the composting process, ventilate the first 21 days, turn the compost once every 7 days, add water to make the moisture content of the material 45%, and the composting ends after 42 days. Another two groups were selected for the same treatment as a parallel experiment.

Embodiment 2

[0029] Take 1kg of straw segments cut into 3-5cm length and 4kg of pig manure, put them into a heat-insulated box-type reactor made of 12L foam and install a plexiglass ventilation pipe at the bottom, add 0.6kg of glass with a particle size of 0.5-2cm Pumice, fully mixed, adjust the moisture content of the mixed material to 50%, use a vacuum pump with timer control to ventilate the pile, the ventilation rate is controlled by a glass rotor gas flowmeter, and the ventilation rate is set at 0.01m 3 ·(h·kg) -1 During the composting process, ventilate the first 14 days, turn the compost once every 7 days, add water to make the moisture content of the material 60%, and the composting ends after 42 days. Another two groups were selected for the same treatment as a parallel experiment.

Abstract

The invention discloses a method for promoting compost maturity. Straw, pig manure and glass pumice are fully and evenly mixed and then composted, ventilation is conducted in the composting process, the mass ratio of the added straw to pig manure is 1: (4-5), and the adding amount of the glass pumice accounts for 5%-15% of the mass of the pig manure. The addition of the glass pumice not only promotes the degradation of organic materials in the compost and the humification degree of the compost materials, but also can adsorb and fix ammonia in the compost materials. The selected glass pumice for promoting compost maturity is cheap and easy to obtain, and has important practical significance for application and popularization of compost.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a method for promoting the maturity of compost. Background technique [0002] Rural solid waste mainly includes straw, tail vegetables and livestock and poultry manure. Direct returning to the field is an economical and direct means of comprehensive utilization of straw, but small-scale farmers' family management leads to the dispersion of straw resources, which is difficult to manage uniformly and increases the risk of discarding and open burning. The landfill or stockpiling of these solid wastes produces leachate that spreads along with the surface runoff, polluting the surrounding water bodies and soil. [0003] Aerobic composting is a method of using aerobic microorganisms to absorb, oxidize and decompose organic matter in straw and livestock manure under aerobic conditions, and convert them into farmyard manure. At present, there are many research results on composting, ...
