These last days of March, in the fields of the coastal district of Hau Loc, farmers are focusing on taking care of 6,200 hectares of crops for the 2024 winter-spring crop (including 4,490 hectares of rice), increasing the value and efficiency of agricultural production.
Hau Loc Irrigation Branch operates Hau Village Pumping Station (Phu Loc Commune) to irrigate crops in the winter-spring crop.
Agricultural production in the area faced many difficulties because in March 2024, salinity had penetrated deep into the coastal area of Hau Loc. Salinity measured at Lien Loc 2 pumping station was up to 24 parts per thousand, Loc Dong sluice was 8 parts per thousand,... Due to salinity and low water level of Len River, there were times when water could not be taken for the inland pumping stations to operate.
In order to provide enough irrigation water for farmers in the area to sow and care for crops, striving to achieve a total food output of 29,841 tons in the 2024 winter-spring crop, the People's Committee of Hau Loc district and Bac Song Ma Irrigation One Member Co., Ltd. have directed Hau Loc Irrigation Branch to take full advantage of water resources, proactively operate key pumping stations, and be on duty at Loc Dong sluice gate, combined with regulating water from Hoang Khanh pumping station (Hoang Hoa) through the old Hospital sluice gate to Tra Giang river, ensuring enough water to serve people in caring for and watering crops.
Units and localities in Hau Loc district have synchronously implemented solutions to overcome difficulties, combat drought and saltwater intrusion in the 2024 winter-spring crop. Hau Loc district People's Committee has focused on directing communes to continue dredging canals, water intakes and water storage canals for pumping stations to operate; manage freshwater sources for economical and effective irrigation; prepare oil pumps to combat local drought; review and convert some coastal crop areas that are frequently affected by saltwater intrusion to aquaculture.
In recent months, Hau Loc district has mobilized communes and towns to carry out irrigation works in the dry season, digging and filling inter-commune and intra-field canals with a total volume of 33,680m3 of mud and soil (an increase of 34% compared to the plan assigned by the Provincial People's Committee) and clearing 535,010m2 of duckweed and grass (an increase of 7% compared to the plan assigned by the Provincial People's Committee) to facilitate the flow of water from the project's headquarter to the fields. Communes in the eastern part of De canal have dug and filled intra-field drainage canals to proactively store fresh water for agricultural production when the water source for pumping is lacking due to saltwater intrusion.
Chau Loc pumping station (Trieu Loc commune) pumps water to irrigate 1,000 hectares of winter-spring crops.
Based on the local cropping schedule, Hau Loc Irrigation Branch has proactively and promptly operated pumping stations along the Len River to pump fresh water into the fields. The Branch has directed irrigation groups and clusters to assign staff to take turns working 24/7 at pumping stations and water intakes along the Len River, measuring and checking salinity at water intake sluice gates every 15 minutes, so that when there is a source of fresh water, the pumping stations can be operated at full capacity. Installing oil pumps and field pumps to pump water for irrigation. Proactively overcoming the situation of salinity in the Loc Dong sluice, Bac Song Ma Irrigation One Member Co., Ltd. has directed the Branch to operate at full capacity the Dai Loc pumping station and Chau Loc pumping station (in Trieu Loc commune) to add water to the Tra Giang River to create a source of fresh water to ensure the operation of the inland pumping stations.
Workers of Hau Loc Irrigation Branch are on duty to measure salinity at Loc Dong sluice (Phong Loc commune).
Implementing the approved irrigation plan for the 2024 winter-spring crop, Hau Loc Irrigation Branch has operated irrigation according to the plan in a scientific, appropriate, effective and water-saving manner. Previously, the branch inspected and evaluated the production capacity of 27 pumping stations and irrigation systems in the area to repair damage, prepare necessary materials and equipment, replace all small capacity pumps with pumps with a capacity of 1,400m3 /hour, ensuring 100% of pumping stations and construction systems operate well when required. Assigning staff to inspect, closely follow the area, take shifts at the project's focal point, dredge canals, suction tanks, channels leading to pumping stations, and culverts along Len River with a volume of nearly 10,000m3 of mud and soil dug and filled to ensure smooth water channels from the focal point to the field; Close sluice gates in irrigated areas to reserve water for the end of the canal, highlands, and saline areas to soak the rice fields to limit the lack of water in the fields, causing acidity and salinity, affecting the growth of crops.
Dredging canals for irrigation in Hoa Loc commune (Hau Loc)
According to the forecast of Hau Loc Irrigation Branch, in early April 2024, when rice in the area blooms, it will be a time of hot weather and saltwater intrusion, about 700 hectares of rice in Hau Loc district are likely to lack water.
Along with the synchronous implementation of solutions to serve irrigation water, proactively prevent and combat saline intrusion in Hau Loc district, to create conditions for coastal communes in Hau Loc to proactively overcome saline intrusion and protect crops, the province has invested in building a number of irrigation works in Hau Loc district to serve irrigation water for agricultural production in the area.
