Earthworm, in the textbook, it is a loose soil, help plant growth of beneficial insects, in medicine, it is one of the important Chinese medicinal materials in the mainland, when it drilled into the forest of Wanning, it became to help farmers get rich and increase income, pull the development of upstream and downstream industries "money string".
Since the beginning of this year, Wanning has listed the Guangdilong industry as one of the eight major industries for the key development of Wanning City, taking Beidazhen as the first pilot area to explore and create an industrial development model of "under-forest economy + ecological cycle + soil improvement". At present, the breeding area of Guangdilong in Beida Town has reached 300 mu, taking the first step from scratch, and projects such as seedling cultivation and bait processing are also steadily advancing.

Good to feed the high value
"South Drift" Guangdi Dragon Forest Under the "Migrant Worker"
On June 15, in a rubber forest in Xiasan Village, Beida Town, Wanning, the thick soil under the rubber forest was turned over, and thick earthworms squirmed in the wet soil. Farmer Huang Hui picked up an earthworm and carefully observed it, nodded with satisfaction, and in another month, the earthworms could be listed.
Ground dragon, commonly known as earthworm, Huang Hui introduced the variety is ginseng ring hairworm, because the main production in the two Guangdong area, so also called "Guangdi dragon", this year, Wanning officially included the Guangdi dragon industry in The wanning city key development of one of the eight major industries.
The Peking University Huilong Breeding Family Farm operated by Huang Hui is the largest Standardized Breeding Base of Guangdi Dragon in Wanning, covering an area of 82 mu and currently cultivating 45 mu. In April this year, Huang Hui introduced the first batch of seedlings from Guangxi, and after more than two months of exploration, Huang Hui has been quite experienced in the breeding of Guangdi dragon.
The fertilizer pH value in fermentation is less than 6.5 is suitable for Guangdilong to eat, and the picture shows Huang Hui using instruments to detect fertilizer pH.
"It is not difficult to breed a broad-ground dragon, as long as the soil moisture is controlled and the high temperature and sun are avoided, and then the nutrients are scientifically matched, basically a good harvest can be achieved." Huang Hui said. In the re-breeding base, there are often water pipes under the rubber forest to ensure soil moisture, the gullies next to the water pipes are convenient for drainage, the straw laid on the ground can effectively prevent light, and every one meter there is a lump of processed cow dung, which is the fertilizer of Guangdilong. At night, the Guangdi Dragon will drill on the ground to feed, and then return to the underground, Huang Hui will go to the forest every day to check, if you don't see the Guangdi Dragon, it means that this group of "little guys" are alive and well.
Huang Hui also built 7 test pools in the base for a more intuitive understanding of the growth habits of Guangdi dragon and the adaptability of different species of Guangdi dragon to the base environment, so as to facilitate more scientific breeding.
The test pool is mainly used to understand the growth habits of Guangdilong and the adaptability of different species of Guangdilong to the base environment, so as to facilitate more scientific breeding.
It is a large species of 21 common earthworm species suitable for breeding, with a heterogeneous and extensive diet, feeding on manure, straw, deciduous leaves and other organic saprophytes in the soil. Dilong itself has a high medicinal value, is one of the important Chinese herbal medicines in the mainland, due to the scarcity of production, the supply exceeds demand, the price has continued to rise for ten years, which is also one of the main reasons why Huang Hui looks at it.
Although the income has not yet been obtained, the business account Huang Hui has calculated clearly. "Now the Guangdi dragon dry goods on the market is as high as 140 yuan per catty, and under the condition of proper management, the annual output of about 400 kg of dry goods per mu is conservatively estimated, and the annual output value of each mu can reach 40,000 yuan, and the income is very impressive." Huang Hui said.
Every day, Huang Hui had to check the growth of the Guangdi Dragon, and the picture showed him using the seedling machine to introduce the Guangdi Dragon into the ground to check the growth.
Huang Hui raised a two-month-old Guangdi dragon, with a thick and vigorous body.
Small "characters" are big "characters"
The "Key Link" of the Green Circular Agriculture Model
All along, the source of Guangdi dragon products mainly rely on wild capture, wild Guangdi dragon resources are facing depletion, from the perspective of the whole country, there have been a number of regions to develop Guangdi dragon breeding, the industrial development is relatively mature is Guangxi region, but by the restrictions of breeding land, it has not been able to form a large-scale development.
This year, the Wanning Municipal Party Committee and Municipal Government issued a document listing Guangdilong as one of the eight major industries for the key development of Wanning City, which is the first document in China to list Guangdilong as a key development industry at the government level.
Wanning did not have a guangdi dragon breeding foundation before, why was it included in the eight major industries?
"First of all, Wanning has good conditions for breeding Guangdi dragons." Huang Qiongjun, deputy director of the Wanning Municipal Bureau of Agriculture and Rural Affairs, said that Wanning's humid climate and abundant rainfall can provide superior soil conditions for Guangdilong. The development of Guangdilong aquaculture is an important model for the development of the under-forest economy, and there is no need for new land use. The city's vast understory land area provides ample shading space and bait for Guangdilong.
"Secondly, Guangdilong is both the need of Wanning's economic development and the need of green development." Huang Qiongjun said that for a long time, due to the over-cultivation of cash crops in Wanning, the soil compaction and fertility in some areas have been insufficient, which in turn has led to a decline in crop yields, and through the underground activities of Guangdilong and the swallowing and excretion, the compacted soil can become loose and porous, aerated and water-permeable, improve soil performance, and promote crop yield and income.
In addition, Guangdi dragon has a mixed and extensive diet, likes to use manure, straw, deciduous leaves and other organic humus in the soil as food, which can effectively reduce agricultural non-point source pollution, promote rural garbage classification and improve the living environment, "It is estimated that Guangdi dragon breeding can consume about 10 to 20 cubic meters of rice straw per mu per year, and after the implementation of large-scale breeding, a large amount of rice straw will be consumed, becoming a new model for the resource utilization of straw off the field." Huang Qiongjun said.
More importantly, the breeding of Guangdilong helps to promote the development of upstream and downstream industries and promote the formation of a green circular agriculture model.
From the upstream industry point of view, Guangdilong feed to cattle manure, with the expansion of the scale of breeding, the demand for cow dung will be increasing, can drive the development of the cattle industry, the development of the cattle industry requires a large amount of silage, but also to promote the planting of corn, peanuts, pasture and other crops; From the perspective of downstream industries, Guangdi Longde manure is a high-quality organic fertilizer, after large-scale breeding, it can give birth to the processing industry of Dilong organic fertilizer, and then strengthen the planting of high-end fruits and vegetables.
At present, BeidaZhen has explored the ecological breeding mode under the dragon forest in Guangdi. Growing the cash crop Banlan while breeding The Broad Ground Dragon under the rubber forest is a lot of success.
Develop the Guangdi dragon industry
What is Wanning going to do?
It is understood that at present, the development of the Wanning Guangdilong industry is mainly led by the Municipal Agriculture and Rural Bureau, and Beida Town is responsible for promoting it. As early as last year, Beida Town formed an inspection delegation, successively to Liangguang, Anhui and other places to investigate, but also invited relevant enterprises and experts to Peking University to observe, at present, Beida Town has set up a town-level industrial project work leading group, established a special work class, "with the strength of the whole town" to focus on the development of Guangdi dragon industry.
Recently, the government of Beidazhen drafted the "Cooperation Plan for the Guangdilong Aquaculture Industry Project in Beidazhen, Wanning City (Draft for Comment)" and commented on relevant industry departments. Among them, two projects were mentioned to establish a Demonstration Base for Breeding and Breeding of Guangdilong Conservation and Breeding and a Manure and Straw Treatment Center in Beida Town.
The "Plan" proposes to select 5 village collectives such as the three villages in Beida Town as cooperative village collectives of Guangdilong Conservation Breeding and Breeding Demonstration Base, and plan to invest 2.6 million yuan as the fixed assets of the village collectives; Three village collectives, including Jiandong Village, were selected as cooperative village collectives for manure and straw treatment centers, and 2.22 million yuan was invested as the fixed assets of the village collectives. The Peking University Town Government invested funds for the 8 village committees to build the infrastructure of the Guangdilong Conservation breeding and breeding demonstration base and the manure and straw treatment center.
In addition, at present, Beidazhen has explored two guangdilong industrial development models of "family farm" and "enterprise investment". Through the "family farm" model, farmers are mobilized to breed Guangdi dragons independently; Through the introduction of enterprise investment, unified technology and management means, expand the scale of industry.
On May 23, Beidazhen and Herun Earthworm Research Institute (Hainan) Co., Ltd. signed a cooperation framework agreement for the Guangdilong Project, adopting the cooperation model of "government + enterprise + farmer" to establish a Guangdilong industrial chain integrating breeding, breeding, primary processing and deep processing in Beidazhen.
"BeidaZhen is the core township of Wanning City to undertake the industrial chain of Guangdi Dragon, rich in natural resources, which is very suitable for Guangdi Dragon breeding." Zhao Tianguang, head of Herun Earthworm Research Institute (Hainan) Co., Ltd., introduced that after the enterprise settles in, it will build a 2,000-mu ecological seed preservation and breeding base in Beida Town.
It is understood that Beida Town has developed about 300 acres of guangdi breeding base. Chen Zaidao, deputy secretary of the Party Committee of Beida Town, introduced that after the successful cultivation of seedlings in the GuangdiLong Conservation Breeding and Breeding Demonstration Base Project, the residents of all villages in Beida Town will be mobilized to carry out large-scale breeding, and the scale of breeding is planned to increase to 3,000 mu next year.
