Let the small earthworms activate the green circular breeding chain

May, when lilacs are in full bloom, is busy.

In the vegetable greenhouse No. 38, Baosu Village, Huangheshao Town, Saihan District, the red tomatoes are particularly attractive in the sunlight. Wu Yonghe, a villager who is busy picking, has a bright face, because under the leadership of the "first secretary" of the village, the experiment of raising earthworms under plastic film is carried out in the gaps in vegetable fields planted with green manure. Taking planting 80 kilograms of earthworms per mu as an example, it is estimated that the income of earthworms, increasing vegetable production, and reducing fertilizer input will be increased by at least 5000 yuan in one shed. Wu Yonghe said that if the experiments in these two greenhouses are successful, it will not only give tomatoes "double insurance" for organic fertilizer. Moreover, it can also walk out of a fully closed green economy industrial chain based on the production of organic green manure with vegetable straw, the cultivation of overwintering fruit vegetables, the cultivation of earthworms in vegetable greenhouses, the feeding of earthworms to scattered chickens, the cultivation of earthworms in chicken manure, the cultivation of organic vegetables in earthworm manure and the "greenhouse claim of vegetables in urban families".

This spring, Yunsen is half happy and half sad. As the "first secretary" of the village from the Municipal Economic and Information Commission, he is pleased that organic cucumbers, oil hyacinth and other vegetables that helped villagers grow green manure have been docked with the market last winter, and some vendors are willing to come to buy them; stupid eggs produced by earthworms have also been successful and favored by consumers. What worries him is how to popularize green manure planting and earthworm farming in the village on a large scale to form a circular economy industrial chain and make full use of some idle greenhouses.

Baosu Village, more than ten kilometers away from the urban area, is a village dominated by vegetable cultivation and supplemented by aquaculture. Although many vegetable greenhouses have been built in the village in order to promote the development of villagers, it is difficult to connect with the market due to the relative lack of planting experience, lack of concentration of vegetables, lack of scale, and so on. in addition, due to the constraints of regional climatic conditions and the influence of vegetable prices in Shandong and Hebei, many greenhouses are idle.

Since serving as "first Secretary" in the village in September 2014, in the face of the current situation in the village, Yunsen introduced an organic liquid fertilizer fermented from the stems, leaves and roots of abandoned plants into Baosu Village in June 2015. used in the cultivation of existing vegetables, the experimental results are gratifying. Since then, Yunsen has come up with new ideas: on the one hand, he helps farmers set up professional cooperatives to solve the problem of selling agricultural products; on the other hand, he uses three modes such as "private customization" to rent vegetable sheds to help villagers increase their income. At the same time, Yunsen went out to inspect at his own expense and introduced the earthworm breeding project to develop a circular industrial chain-- driving villagers to use green manure and earthworm manure to grow organic vegetables and use earthworms to raise earthworm laying hens. Then solve the pollution-free treatment of cow manure through earthworms.

Yun Sen said that earthworms are good things. Their feces can not only be used as organic fertilizer, but they can also dispose of kitchen waste, and they can also be sent directly to pharmaceutical factories to extract the ingredients needed in drugs. At present, it has reached a cooperation agreement with an animal husbandry enterprise to develop the earthworm industry, and has signed an intentional cooperation agreement with Helin County to carry out earthworm breeding on the 1000 mu of land provided by the county.
