5000 Zero-emission breeding balance of live pigs in Liuyang

With the continuous development of the model of "balance of planting and cultivation", vegetable cultivation has become an important industry in Murakami.

Cheng Zhanglong, head of the Lujue farming Cooperative in Shengping Village, Guankou Street, is now most worried about not raising pigs, but growing vegetables.

As a major local pig farmer, Cheng Zhanglong's annual pig stock is maintained at about 1000. Since 2013, through breeding and breeding, his more than 1000 pigs have gradually achieved "zero emission". In order to consolidate the effect of "balance between planting and cultivation", he is currently planning to expand the vegetable planting area of cooperatives.

In Shengping Village, like Cheng Zhanglong, there are 43 farmers who achieve "zero emission" through planting and breeding balance. Since the whole village promoted the "planting and breeding balance" in 2014, 5000 live pigs in the village have achieved "zero discharge", truly realizing "no flow of fertilizer and water to outsiders' land".

Invest more than 200,000 yuan to try "planting and breeding balance"

Yesterday, the reporter walked into the Baini formation in Shengping Village. Under the large steel shed, lettuce and cabbage are growing rapidly, and the green one is very gratifying. "vegetables grow better because the main fertilizer is fermented pig manure." Cheng Zhanglong, who was busy inspecting the pipeline, looked proud.

In 2007, taking a fancy to the hot pig breeding market at that time, Cheng Zhanglong built a farm in Murakami and expanded the scale to an annual stock of 1000 through self-breeding. "the scale has become larger and the pollution has become more serious." Cheng Zhanglong told reporters that the pungent stench and pig excrement made the villagers complain.

"if you don't find a way, you won't be able to raise pigs sooner or later." Cheng Zhanglong is soberly aware of this fact. In order to reduce pollution, Cheng Zhanglong successively tried the "dry-wet separation and discharge technology" and so on, but in the end, they all had to give up because of too much labor. In 2013, Cheng Zhanglong began a new attempt to control pollution-this time he transferred more than 150 mu of vegetables, invested more than 200,000 yuan, built 11 new biogas digesters, 3 septic tanks, more than 600 meters of biogas liquid transportation pipeline, and initially completed the "planting and cultivation balance" model.

To solve the problem of aquaculture pollution, we need to use the method of development to adjust the production relationship between aquaculture and planting industry. If the use of livestock manure in planting production is a return to the biological chain, it can not only solve the pollution problem of aquaculture, but also solve the problem of fertilizer used in farming, reduce the amount of chemical fertilizer, and produce organic and environmentally friendly safe food. it is a good thing to kill many birds with one stone, which is the connotation of the balance of planting and cultivation.

"Pig manure is poured into the biogas digester, and the fermented biogas slurry is transported to the field through a pipeline, and the biogas residue is made into granular fertilizer takeout." Cheng Zhanglong said that according to the allocation standard of one mu of land for three pigs, in the first year of operation, he basically did not buy fertilizer for more than 150 mu of vegetables, and the vegetables grown were tastier. Pig manure water watering vegetables, vegetable leaves can also raise pigs, to achieve a three-dimensional cycle.

From feces from farms to fertilizers for organic vegetables, more and more villagers see economic benefits from Cheng Zhanglong's "balance of planting and cultivation" model. In order to further expand the scale, with the help of the Municipal Environmental Protection Bureau, the "planting and breeding balance" model was officially promoted in the whole village in 2014, and was incorporated into the Changsha "planting and breeding balance" project.

"Last year, I raised more than 170 pigs and matched 10 mu of vegetables. although the price of pigs was weak, the vegetables earned more than 70,000 yuan." Villager Wang Nanqi is the beneficiary of the "balance of planting and cultivation". "in the next step, I plan to continue to optimize vegetable cultivation and further improve the efficiency of the balance of planting and cultivation."

"at present, 44 farmers in the village have adopted the 'breeding balance' model, and more than 5000 live pigs have achieved 'zero emission'." The person in charge of Shengping Village told reporters that with the continuous promotion of the "balance of planting and cultivation", Murakami has also developed more than 200 mu of fruit and more than 200 mu of selenium-rich rice. In the next step, Murakami will further optimize the industrial structure and build a modern agricultural industrial base on the basis of continuing to promote the "balance of planting and cultivation".
