Two years ago, Qingdao Changsheng Ridian Photovoltaic Agricultural Industrial Park introduced an earthworm breeding project, earthworm growth mainly uses recycled cow manure and crop straw as bait to achieve the reuse of organic waste, and also promote the circular development of
agricultural economy.
Today, after nearly two years of development, the earthworm breeding area has expanded to more than 370 mu, with an annual output of more than 1,000 tons of earthworms, creating more than 20 million yuan of economic benefits
a year.
Crop straw for cow dung
It became a delicious meal for earthworms
Recently, media reporters came to the earthworm breeding photovoltaic greenhouse in the photovoltaic agricultural industrial park of Qingdao Changsheng Ridian Solar Energy Technology Co.
, Ltd.
, in the dark and humid greenhouse, opened the earthworm breeding bed covered with straw curtains, and saw the dense earthworms attached to the breeding bed made of cow dung and straw constantly wriggling
.
"The roof of the solar photovoltaic greenhouse can use solar panels to generate electricity, and the dark environment in the shed is particularly suitable for the growth habits of earthworms, which is really a double kill
.
" Sun Jian, the person in charge of the earthworm breeding project in the industrial park, introduced that the cultivation of earthworms in the solar photovoltaic greenhouse can well control the temperature, humidity and ventilation, which greatly meets the environmental requirements for the growth and reproduction of earthworms, and the air, water quality and soil near the breeding base are not polluted
.
In addition to the very suitable growing environment, the bait needed for earthworms to grow is also customized, and fresh cow manure and crushed crop straw are matched in a certain proportion, and then earthworm seedlings are cultivated and grown
in a "customized package".
And the breeding environment and bait in the photovoltaic greenhouse have reached the standards
for purchasing earthworms by pharmaceutical companies.
It is understood that earthworm breeding not only achieves pollution-free, zero-discharge, harmless biological transformation of solid organic wastes such as livestock manure and crop straw, but also creates high economic value
.
"Earthworms must maintain a certain amount of moisture every day for growth, and they can generally be sold after 45 days
.
" Sun Jian said that the products made of the earthworms they breed mainly include fresh earthworms, frozen fresh earthworms, earthworm eggs, dried earthworms, vermicompost, vermicompost compound fertilizer, vermicompost organic fertilizer, etc.
, earthworms are mainly sold to some pharmaceutical enterprises across the country, while the vermicompost produced by the growth of earthworms is sold to some flowers, fruits and vegetables, vegetable seedlings and other planting bases as organic fertilizer
.
Earthworms are sold for 15 yuan per catty
Raise one mu and earn 560,000
"At present, a photovoltaic agricultural greenhouse covering an area of 5 acres can produce about 12 tons of earthworms a year, and the price per catty is about 15 yuan, and a greenhouse can create more than 300,000 yuan of economic income
a year.
" Sun Jian said that their earthworm breeding project was introduced in October 2014, and now with the continuous expansion of the breeding scale, the industrial park has cultivated a total of more than 370 mu of earthworms, with an annual output of more than 1,000 tons of earthworms and more than 20,000 tons of vermicompost, and can achieve a net income
of at least 20 million yuan a year.
It is understood that because the bait is continuously digested and absorbed, the breeding bed for cultivating earthworms will be replaced once every half a year, and the whole project can digest more than 20,000 tons of cow manure and more than 5,000 tons of crop straw a year, which is not only environmentally friendly and pollution-free, but also can promote the circular development of
ecological agriculture economy.
In August this year, the Qingdao Agricultural Maker Space built by Qingdao Changsheng Ridian Solar Technology Co.
, Ltd
.
officially obtained the national public innovation space certification of the Ministry of Science and Technology, and was included in the national incubator management system, becoming the first national incubator carrier in the agricultural field 。 Since its use in 2015, Qingdao Agricultural Maker Space has successfully incubated 47 small and micro enterprises and maker projects, made seed rounds of investment totaling more than 28 million yuan for 11 of them, and tutored 2 enterprises to obtain external financing of more than 11 million yuan, driving more than 500 jobs and absorbing more than 100 fresh graduates
