1943 North Anhui Irrigation District started construction, 1944 Initial irrigation. 1945, Yanbian Korean immigrants planted paddy fields 1476 mu. Later, Han people from various townships came to northern Anhui to develop paddy fields, with a maximum of1.2000 mu. After three years of economic difficulties, the paddy field area gradually declined, but it developed again after 1979. By 1985, the paddy field reached 22,000 mu. The yield per mu reached 530 Jin, and the total output was 6.5438+0.2 million Jin.

In Qixingpao irrigation area, there was no dike before 1962, and paddy fields were often threatened by floods. Qixingpao Town starts from Gaolihao to the drainage outlet of irrigation area 1962, with a new dike of 6. 1 km. 1964 regulation irrigation area, excavation 1 main water conveyance canal and branch water conveyance canal, length 10.9 km, earthwork 22 10000 m3, excavation 1 main drainage canal and branch water conveyance canal, length10. At that time, the irrigation area was 0.3 ~ 0.4 million mu. After the rectification of 1978, the irrigation area and Yueyapao irrigation area were merged into one irrigation area. From 198 1 to 1985, the irrigation area reached 0.72 million mu and the total output reached 5.04 million Jin, which is a good irrigation area with more than enough funds in Baoqing County.

In Toudaogang Irrigation District, 3,000 mu of paddy fields were planted on 1934 when people were hired to dig in the Xie Jia section (the big landlord Xie Wenyan). Old channel 196 1 abolished. Reconstruction of Nanshan (Chuankou) Channel Project in Hongshan East, 1962 started initial irrigation. 1975, the county was included in the rectification and reported to the district for investment approval. The basic rectification was completed in two years from 1977. Completed various waterways and two drainage channels. 1978 rose to 0.35 million mu. 1982 irrigated 0.6 million mu, 1985 reached 0.85 million mu. The yield per mu is 6 10 kg, and the total output reaches 810.85 million kg.

Xingfu irrigation area, built at the beginning of 1959 and 1960, with a maximum area of 0.75 million mu. 1977 after the completion of the rectification plan, the region approved an investment of 909,438+0,000 yuan. 1978, Baoqing Town and Shili organized migrant workers 170, and built a permanent sluice 1 seat of Baoshi River, with a total length of 30.8 meters, a sluice height of 1.7 meters and a flood discharge of 68 cubic meters per second. The investment is 368,000 yuan. At the same time, all the structures from Toudaohe to Fujiacun main canal will be completed within three years.
