Pathway supply side, back home to see "three farmers": fish do not change water, vegetables do not fertilize.

Fish dishes symbiotic farm scene (Xu Jingzhan)
home from vacation to visit relatives, was invited by friends to go out to play. But now is the cold winter, Shandong Yantai, the northern seaside town where can go to play? A friend slyly smiled, "Secret." "
friends drive from the city to the suburbs, to the countryside, along the bumpy road, it is not easy. Just when I had no idea why, he took me to the village of Yulin shop in Muping District.
In my impression, here is just ordinary countryside, early years, is endless farmland, the village people's ancestors face the loess back to the sky, planting wheat corn or peanuts, and later built a plastic shed to grow vegetables red fire for a while, but now fewer and fewer villagers, the sheds are in disrepair and abandoned.
told me that there are now several sheds contracted down and soilless cultivation, called Ivy Farm.
Abandoned sheds planted ecological agriculture
I thought that individual farms have long been nothing new, and not to say that many grain-producing areas in order to increase income to adopt a similar business model, even in the north to wide this inch of land and gold places, there are many, the so-called difference is just decoration style is different.
in the sheds of the Ivy Farm, however, is another world: a variety of flowers and plants with lush branches and pleasant growth. On closer inspection, the ground of the shed is a deep-dug fish pond, the fish are free, the water is also clear bottom, green plants are planted in the form of soilless cultivation in the planting tank, the pool and planting tank hanging above the independent aerosol cultivation planting bucket, everywhere flowing water.
was in the spirit of God, the staff in Pengfei with tea greeted, laughing Yingying Said: "This is just picked out the mint brewed tea, taste." "Clear a mouthful of mint tea, full of aroma, heart-warming.
"This is a big shed where fish dishes live together. Yu Pengfei said, "Simply put, it is a three-dimensional ecological model of fish and vegetable breeding, no pesticides, no fertilizer." The whole system through the pump cycle, the fish droppings and bait residue in the microbial action into plants can absorb nitrates and other nutrients, water into clean water and back to the fish pond, can achieve fish without water change, vegetables do not fertilize. "
" now everyone is advocating the return to nature, from a safety and health point of view to choose agricultural and sideline products, we have a variety of fresh vegetables, fruits, to taste the taste of childhood, so it is easy to get consumer recognition. Yu Pengfei said.
At the same time, soilless cultivation lifted the shackles on plant growth space, through the design can create a beautiful natural landscape, greenhouses can be planted in different areas, colors, levels of flowers and trees, supplemented by fish and birds, like a natural forest oxygen bar, is a good development of eco-tourism content and direction.
eco-agriculture is not as simple as raising fish and vegetables
when I was a child, I also lived in the countryside, the village has reservoirs, farming fish way, more or less heard.
an acre of land, 34% of the ground has actually become a field and path, and in order to increase production and pest control, pesticide fertilizer has always been sprinkled and sprinkled, sprayed and sprayed.
one side of the fish pond, in order to ensure smooth production, the need to take filtration, precipitation, oxygenation and other ways, once the problem, water quality deterioration, heavy losses.
, it's easier said than done to raise fish and vegetables.
Yu Pengfei took me to visit the farm while saying: "The earliest is from abroad to understand this model, everything in the country is from scratch, the first half of the time, fish do not live, grow vegetables not long." But
, fat fish and lush flowers and vegetables bear witness to everything.
" Now we use fish vegetable symbiosis and aerosol cultivation compound three-dimensional planting model, planting area increased several times, while avoiding the soil spread of most pests and diseases, greenhouse is a relatively closed environment, can block the invasion of foreign pests, and with some sticky insect boards, insect lamps and other physical methods can achieve zero pesticide production. Many of the plants here look bigger than conventional ones. Yu Pengfei said, "This form of watering fertilization has been automated, all that is needed is to collect vegetables and carry out daily simple management, this 900 square meters of shed only need a worker can manage, can employ farmers in nearby villages, simple income than before to plant land is higher." "
not only business opportunities but also
now, this is Yantai primary and secondary school students science education practice base. "During the holidays, many primary and secondary schools will organize students to come here to visit and study, to introduce natural science knowledge and popularize the principle of soilless cultivation as the main content, but also to train students ecological cycle and environmental protection concept, we have to receive a dozen batches a year, many times, there are more than 100 people at a time. After
nearly 7 years of research and development and practice, we have explored a more perfect and stable production model.
"Because our farm is currently primarily a technology research and development and display base, not very large, we hope to combine agriculture and tourism, catering, science and more cultural creativity through practice to create a new recyclable, replicable space. "In this way, more added value can be added to traditional agriculture, eliminating the need for over-reliance on pesticides and fertilizers for efficient and safe production. "
is relatively mature, how to promote it becomes the key."
, there are enterprises to come to the door to introduce Ivy's technology and model. In 2016 alone, Ivy reached agreements with nearly 10 companies, and in the first half of 2017, the number of contracts signed exceeded last year's.
, on the other hand, local government departments are also actively following Ivy's development. "A lot of departments have also come to visit and research, the city tourism bureau, agriculture bureau, science and technology bureau, education bureau, etc. have been closely watching us." Zhao Yunliang said.
the way back, with friends to talk about the recent experience, I sighed: "If over time, this model and concept can be popularized, the future of rural ecology is certainly better."
2017 Central Document No. 1 proposed to vigorously promote the breeding model of high-efficiency ecological cycle, and at the same time, to promote the deep integration of agriculture, forestry and tourism, education, culture, health and other industries through the use of "tourism plus" and "eco-plus" and other models.
future, breeding and breeding combinations like Ivy Farm will gradually reflect the advantages, so that more people see the business opportunities inherent in agriculture, so that more farmers get real benefits. (Reporter Xu Jing)
