Example Embodiment

[0094] Embodiment 1: earthworm species and addition density screening of garden waste composting

[0095] Earthworms can devour garden wastes containing a large amount of lignocellulosic substances and transform them into humus-like substances, that is, vermicompost, that is, nutrients such as N, P, and K in organic wastes can be transformed into nutrients that are easier for plants to absorb and utilize. form. The maturity index of the composting treatment of garden waste assisted by earthworms is better than that of conventional composting treatment, and can reach the maturity degree in advance, shortening the composting cycle

[0096] 1. Waste pretreatment

[0097] Use a pulverizer to pulverize the garden waste to 0.5cm particles, and place 40kg (dry weight) of pulverized materials for each composting process into a plastic reaction container with an upper opening (length x width x height, 0.6m x 0.8m x 0.65m , the bottom has 20 holes with a diameter of 1 cm for drainage)...

[0109] Example 2: waste particle size screening of garden waste vermicomposting

[0110] 1. Waste pretreatment

[0111] Use a pulverizer to crush the garden waste into particles with a particle size of 0.2, 0.5, 0.8, 1, 1.5, and 2.0, as shown in Table 3;

[0112] Table 3 Treatment of different particle sizes of garden waste vermicomposting

[0123] Example 3: Screening of garden waste vermicomposting methods

[0124] 1. Waste pretreatment

[0125] Use a pulverizer to pulverize the garden waste to 0.5cm particles, and place 40kg (dry weight) of pulverized materials for each composting process into a plastic reaction container with an upper opening (length x width x height, 0.6m x 0.8m x 0.65m , the bottom has 20 holes with a diameter of 1 cm for drainage), after adding urea to adjust the C / N of the waste to 25:1, add water to adjust the humidity of the compost material to 65-70%.

[0126] 2. Aerobic composting

[0127] Carry out aerobic composting according to the 6 different composting methods in Table 5, and each treatment is repeated 3 times, that is, 18 parts of 40kg (dry weight) pulverized waste are respectively placed in the plastic reaction container with the upper opening, and urea is added to adjust the composting time. After the C / N of the waste reaches 25:1, add water to adjust the humidity of the comp...

Abstract

The invention discloses a method for treating garden wastes by utilizing earthworms and a prepared plant culture substrate. The method comprises the steps of carrying out aerobic composting treatment and earthworm composting treatment on the garden wastes in sequence. The garden wastes are composed through utilizing the composting treatment and a composted product is formed, so that resource utilization of the garden wastes is promoted. According to the method disclosed by the invention, in a garden waste composting process, the degradation speed of the garden wastes can be improved, and the growth speed and reproduction speed of the earthworms can also be improved; a composted product obtained by the method for treating the garden wastes, provided by the invention, has balanced nutrients, high nutrient components, a reasonable structure and stable physical properties; the composted product is prepared into a flower plant culture substrate, and the survival rate and ornamental effect of flower plant cultivation can be improved.

Description

technical field [0001] The invention relates to a method for treating garden waste, in particular to a method for treating garden waste by using earthworm composting. Background technique [0002] With the continuous improvement of China's national economy and the rapid development of urban greening construction, the amount of garden waste such as litter, branch trimmings, shrub trimmings, lawn trimmings and residual flowers has also increased sharply. While landscaping improves the ecological environment, the disposal of waste generated by it has become an urgent problem to be solved. The recycling rate of incineration and landfill is low, and a large amount of landscaping waste is discharged into the environment through incorrect methods, which not only occupies precious land resources, but also may cause air, water and soil pollution. At present, landscaping waste disposal not only affects the health of residents and the construction of ecological cities, but also become...
