Approximately 600 hectares of land dedicated to vegetable cultivation in Hai Duong province are applying water-saving irrigation techniques.

Implementing water-saving irrigation systems has brought many benefits to some vegetable-growing areas in Hai Duong.

Water-saving irrigation through automatic sprinkler systems is being applied in some carrot-growing areas in Cam Giang district.

According to our investigation, as of March this year, Hai Duong province has approximately 600 hectares of land dedicated to vegetable cultivation using water-saving irrigation systems.

In 2017, the herb-growing area in Pham Kha commune (Thanh Mien district) was the first to apply a water-saving irrigation system. Since 2019, some carrot-growing areas in Cam Giang district and onion and vegetable growing areas in Kinh Mon town have also started applying this system.

Farmers in Pham Tran commune (Gia Loc district) are applying a drip irrigation system to their greenhouse-grown cantaloupe crops, controlled by software installed on their mobile phones.

In recent years, numerous greenhouse models in districts such as Gia Loc, Nam Sach, Hai Duong City, and Kim Thanh have applied water-saving irrigation technology to most of their vegetable production areas.

Water-saving irrigation is simply understood as providing controlled irrigation water to cultivated land. Farmers in some vegetable-growing areas of Hai Duong are applying several water-saving irrigation techniques such as: drip irrigation (supplying water to the soil in the form of small water droplets from drip emitters placed on the ground near the base of the plants), localized sprinkler irrigation (supplying water to plants in the form of raindrops or mist through a system of sprinklers erected across the field)...

Drip irrigation is a water-saving irrigation technology that is being adopted by many greenhouses in Hai Duong.

To implement this technology, farmers in the province have invested in installing pumps, pipeline systems, etc. Depending on weather conditions, they can proactively regulate water levels with a few simple operations using handheld electronic devices or software installed on their mobile phones. Farmers can operate the water-saving irrigation system remotely within a suitable radius without being physically present in the fields.

Traditional irrigation methods often waste water and cause soil erosion. Excess irrigation water seeps deep into the soil, washing away a significant amount of fertilizer and organic matter from the plant root zone. Water-saving irrigation technology, on the other hand, allows farmers to proactively regulate water resources to suit crop needs, eliminating excess water and losses during irrigation.

Cucumbers grown in greenhouses at Tan Minh Duc Cooperative are thriving thanks to the application of water-saving irrigation technology.

According to the Provincial Department of Crop Production and Plant Protection, the application of this system helps vegetable-growing areas save approximately 30-55% of water and improve economic efficiency by 10-30% compared to traditional irrigation methods.

Hai Duong province has set a strategy to transform crop farming into a modern, technologically advanced economic sector by 2050. Water-saving irrigation may be one of the solutions encouraged for widespread adoption to achieve this goal.
