The experience of raising ducks in Zizania caduciflora
It was not a sudden idea for farmers in Huishan Town to put ducks in Zizania caduciflora fields. But learned from the "raising ducks in rice fields" in Gaobu Town, Yuecheng District, Shaoxing. Even the ducklings are Shaoxing ducklings.
At first, many farmers were worried that the ducks would trample on the seedlings, and they were also afraid that the ducks would eat the seedlings. "as a matter of fact, ducks don't eat seedlings." Fei Huilin, deputy secretary general of the Provincial Agricultural Technology extension Foundation, said that the leaves of rice seedlings were so serrated that the duck could not swallow its flat mouth. They only eat smooth weed leaves. Zizania caduciflora leaves can't be eaten by ducks.
In order to prevent ducks from trampling on the seedlings, it is usually necessary to wait for the seedlings to grow to a height of 30 centimeters before releasing the ducks after the seedlings have been planted for half a month. The number of ducks should also be controlled, and the more appropriate stocking ratio is 10-15 ducks per mu.
Raising ducks in rice fields and Zizania caduciflora fields are concentrated in summer, and controlling the stocking time has a great influence on the survival rate of ducks. When Jinhua Tangxi Town began raising ducks in rice fields in 2001, ducks were kept in the fields for most of the day. As a result, only five of the 12 ducks per mu survived because the water temperature was too high. Later, the stocking time was adjusted to put the ducks into the field at 5 o'clock in the morning, get back to the shed before 10:00, go out at more than 5 p.m., and come back at 8 p.m. The survival rate rose to more than 90%.
