The cultivation of leeks in Nangong has a long history, but most of them are in a state of self-cultivation and self-feeding because of low efficiency. There used to be a folk saying that "rotten leeks break a knot in one's heart (dish), so you can't eat them and send them to your relatives". In recent decades, the planting of leek in Nangong has gone through the process from field to semi-shady and semi-sunny soil shed, to greenhouse, from scattered planting to demonstration base of 10 thousand mu planting, from conventional planting to pollution-free production, from basket lifting to short supply.
In view of the scattered layout and different standards of leek planting in the field, the city has formulated the development plan of leek and planned the demonstration area of leek planting. 1999 passed the provincial pollution-free product certification, and 200 1 registered the "green and clean" trademark in the State Administration for Industry and Commerce. In 2002, it was named "the hometown of leeks in Hebei" by the Provincial Department of Agriculture. At present, the pollution-free leek production base in this city has reached 28,000 mu, with an annual output of 165438+2000 tons. The average benefit per mu exceeds 8,000 yuan, and the annual income of farmers can reach 65.438+0.8 billion yuan. "Lv Jie" brand pollution-free leeks have been exported to large and medium-sized cities such as Beijing and Shijiazhuang.
