The winter leisure greenhouse recommends raising geese to get multiple benefits.

In winter, even if the water surface is covered with greenhouses, the temperature in the pond cannot reach the temperature for the growth of Penaeus vannamei. Most of the prawn farmers in Zhejiang have entered winter fallow. In Xinqiao Town, Xiangshan County, most of the shrimp greenhouses here are idle, while Pan Xiaoqiu's home is another scene.

Pan Xiaoqiu began to cultivate Penaeus vannamei in greenhouses since 2005. Penaeus vannamei has high requirements for water temperature. The local temperature is not suitable for shrimp cultivation in November. This situation will last from November to March next year. The greenhouses for shrimp cultivation can only be empty for nearly half a year. Every year to November when shrimp can not be raised, Pan Xiaoqiu shrimp pond sludge clean up, waiting for the next March, April to raise shrimp, these pond bottom sludge often let him very headache. Shrimp feed and shrimp feces accumulated in the bottom of the pond, will produce a large number of nitrogen, phosphorus and other substances, these substances will pollute the water quality, shrimp culture in the coming year is very unfavorable.

In 2009, Pan Xiaoqiu listened to experts at the aquatic technology extension station saying that planting ryegrass could absorb harmful substances from the mud at the bottom of the pond, turning the soil at the bottom of the pond into the same as the newly dug pond, and sowing some grass seeds in the empty shed. After the shrimp pond is planted with ryegrass, the microorganisms in the soil decompose the rich nutrients into some nutrients that ryegrass can absorb, such as available phosphorus and so on. Pan Xiaoqiu's farm has 350 mu, more than 100 large and small shrimp greenhouses, planted with ryegrass, all harmful substances in the mud at the bottom of the pond can be absorbed, ryegrass can be utilized, killing two birds with one stone.

The temperature in the greenhouse was constant and could always be maintained at more than ten degrees Celsius. The ryegrass seeds grew very well in the greenhouse and grew very fast. They could grow to more than twenty centimeters in 20 days, more than ten centimeters higher than on land. Moreover, the grass grew longer and longer like leeks. There were more and more ryegrass in the greenhouse. How should they deal with so many ryegrass?

Xiangshan, Zhejiang Province is the hometown of big white goose. Xiangshan big white goose is a breed of big white goose in eastern Zhejiang Province. It is mainly produced in Xiangshan area of Ningbo. It is famous for its large body and tender meat. It can reach 4 kg in 70 days. Pan Xiaoqiu calculated an account, a gosling more than ten yuan money, after growing up according to the market price a big goose can sell for seventy yuan money, excluding labor costs, etc., each goose profit about twenty yuan. Moreover, the cycle of raising geese is short. Xiangshan has a local saying: just eat just pull, 60 days to sell, raising two batches of geese can just fill the idle period of raising shrimp.

Pan Xiaoqiu adapted to local conditions and raised the geese in this greenhouse covering an area of more than four acres. The other sheds were planted with ryegrass. In the shed with steel wire and bamboo set up a screen, the goose home on the screen, built a shed in the net farm. The screen set up with bamboo piles and steel wires is very strong, and the connection between the screen and the screen is covered with wooden boards. There is no problem for people to walk around and feed freely in the middle. The cost price of a roll of screen is 800 yuan, 3,000 square meters of greenhouse shares 3 rolls of screen 2400 yuan, although the one-time investment looks a little high, but the screen is durable, compared with frequent replacement of straw, the cost is reduced. The so-called eating fragrance, body stick, white swan feed mainly grass, these 8000 geese eat is shrimp shed grow ryegrass, ryegrass because it is planted by themselves, the cost is very low, calculated, a goose eat grass cost only 3 cents a day.
