Yizhou is the largest silkworm production base in the country. In the 2589 natural villages in the city, there are more than 2400 natural villages, 91 thousand families, 410 thousand people engaged in mulberry cultivation and silkworm breeding, and 1 million silkworms were reared annually.

In the past, due to lack of treatment, every year, three million and four thousand tons of silkworm excrement were abandoned by the sericulturers at random and became the "public nuisance" of polluting the environment.

The treatment of Silkworm Feces is a headache for the government of Yizhou.

In order to control the pollution of silkworm excrement, the policy-making layer of the city took great pains, and initially adopted the "government mode" silkworm excrement collection pond, but the operation rate was low, and the pollution was not cured.

After several groping, Yizhou takes the "factory mode" as the embryonic form, and gradually explores the "Marketization Mode".

In the strategy of "moving east to west,"

"Making chemical fertilizer is not the ultimate goal of silkworm excrement in the industrial chain, and the silkworm health care pillow, which came into being at the historic moment, is constantly upgrading the added value of the industry."

Feng Haifeng, Secretary of Yizhou Municipal Committee, said.

The silkworm industry chain of the city has gradually extended from the most primitive cocoon collection to mulberry stalk, silk and silkworm excrement processing.

"The silkworm industry cake can be bigger again."

Chen Jiwa, deputy secretary of the Autonomous Region Party committee, has highly affirmed the practice of Yizhou.

Wei Yujun of Qingshan village in Qingyuan City, in 2009, earned more than 1600 yuan on selling silkworm excrement only.

"Silkworm excrement used to stink the sky, pollute the paddy fields with water, and get the money and fertilize the land since the low carbon treatment."

In the mulberry field of Liu Sanjie Township, silkworm farmer Wei Huanliang sang his own folk songs.

"Silkworm excrement" changed the "low carbon industry" under the recycling economy, making the brook of the third sister's hometown clear again.

Professor Shi Weiyong, a famous silkworm expert and an agricultural extension center of Zhejiang University, commented: "this has opened the national silkworm.

Currently, the three level silkworm excrement collection and pportation network in Yizhou has been initially completed. The introduction of the eastern rural cooperative mode will bring more innovation factors into the billion dollar production of the dunghill.
