Quince Tree Irrigation in France: How to Proceed?

Quick read / the essentials on irrigating quince trees

Irrigation of quince trees is a key factor in ensuring optimal production while preserving water resources. As a specialist wholesale supplier of quince plants , Arboriverse supports producers in implementing efficient irrigation techniques, adapted to the specific needs of this fruit crop.

The most efficient irrigation method for quince orchards is drip irrigation . It ensures precise distribution of water directly to the root system, minimizing evaporation losses and optimizing water absorption. Each dripper, spaced 0.5 to 1 meter apart, delivers a flow rate of 1.5 to 2 liters per hour at an operating pressure of approximately 2.5 bars.

A possible alternative is micro-sprinkling , which is particularly useful for young plants or in warm areas requiring more uniform soil moistening. However, this method results in more evaporation losses than drip irrigation.

Sprinkling on foliage , although less water-efficient, can be used to protect buds against spring frosts by creating a thin layer of ice around them.

Irrigation optimization is based on precise monitoring of soil moisture using tensiometric probes placed at a depth of 25 and 50 cm. Water requirements vary depending on climatic conditions and the stage of tree development, ranging from 6,000 to 10,000 m³ of water per hectare per year .

By choosing to buy certified and adapted quince plants , arborists ensure regular and quality production. Arboriverse , a specialist wholesale supplier of quince plants , offers a rigorous selection of high-performance plants, perfectly adapted to the requirements of modern orchards.

Quince Irrigation: Techniques, Management and Water Optimization

Quince irrigation plays a vital role in the success of orchards, influencing tree growth, fruit quality, and overall yield. In France, several irrigation methods are used depending on soil characteristics and the specific needs of the trees. Careful water management optimizes production while preserving water resources.

Most common irrigation methods for a one hectare plot

Drip irrigation is the most efficient and widely used method for quince orchards. It ensures precise water distribution directly to the root system, preventing evaporation losses and optimizing the trees' water absorption.

A typical system relies on drippers spaced 0.5 to 1 meter apart along the rows of trees. Each dripper delivers a flow rate of 1.5 to 2 liters per hour at an operating pressure of approximately 2.5 bars. Water requirements are estimated at 1.1 mm per hectare per hour. This method allows for frequent and moderate applications, thus avoiding fluctuations in soil moisture that could harm fruit quality. Overwatering can indeed reduce the sugar content of quinces.

Micro-sprinkler irrigation is another effective technique, using small sprinklers placed close to the ground to distribute water in a 2-3 meter radius around each tree. It is particularly useful for young trees or in warmer regions where more widespread soil moisture is beneficial. This method provides better water distribution than drip irrigation, but is more prone to evaporation losses.

Overhead irrigation is less commonly used because it is less water-efficient, but it can be valuable in protecting trees from spring frost. This type of irrigation creates a thin layer of ice on the buds, keeping their temperature just above freezing and thus preventing cold damage.

Regardless of the method chosen, it is essential to manage irrigation according to soil moisture. Installing tensiometric probes at a depth of 25 and 50 cm allows water inputs to be adjusted according to the trees' actual needs. Water requirements vary depending on the quince trees' stage of development and climatic conditions, which requires regular monitoring.

Best irrigation method and implementation

For a one-hectare plot of quince trees in professional production, drip irrigation is the most suitable technique. It guarantees precise water delivery to the roots while limiting losses and facilitating fertigation management.

The system relies on a tree spacing of 5 meters between rows and 4 meters within the row, for a density of approximately 500 trees per hectare. Each row of trees is equipped with two lines of drippers, with a spacing of 0.5 to 1 meter between emitters. The drippers must deliver a flow rate of 2 to 4 liters per hour to ensure uniform irrigation.

The installation includes several essential components: a pumping station, screen and disc filters to prevent drippers from clogging, a fertilizer injector for fertigation, control valves, main and secondary lines, and drip lines.

Setting up the system requires digging a trench for the main line, installing the secondary lines along the rows, and then securing the drip lines to a wire 30 to 50 cm above the ground to prevent them from being blocked by dead leaves or plant debris.

Quince trees' water requirements vary between 600 and 1000 mm per hectare per year, which corresponds to approximately 6000 to 10,000 m³ of water per year for one hectare of orchard. Irrigation should be applied every two to three days during periods of high demand, with sessions lasting 2 to 3 hours to ensure uniform soil moisture.

Irrigation management is based on the analysis of several parameters, including evapotranspiration (ETP), soil moisture measured by tensiometers, and the phenological stage of the trees. To optimize irrigation, it is recommended to maintain an operating pressure of 1 to 2 bars in the drip lines and to carry out regular maintenance of the system, including cleaning the filters and checking that the drippers are working properly.

Signs of water deficiency

Sources do not specify the specific symptoms of water deficiency in quince. However, as with most fruit trees, a lack of water typically results in leaf wilting, yellowing foliage, slowed growth, and reduced fruit size. Prolonged water stress can lead to premature fruit drop and a significant reduction in yield.

Signs of excess water

Because quince trees are particularly sensitive to excess moisture, poorly drained soil or overwatering can cause root rot problems. Prolonged waterlogging in the soil can suffocate the roots, leading to yellowing leaves, general weakening of the tree, and reduced production.

Waterlogged soil also promotes the development of fungal diseases, such as phytophthora, which can cause trees to gradually die back. To avoid these problems, it is essential to ensure good drainage and adapt water supply according to climatic conditions and soil type.

Drainage requirements and irrigation optimization

Quince requires well-drained soil to ensure optimal growth and prevent the risk of root rot. Deep loosening of the soil (50-60 cm) before planting is recommended to improve aeration. Incorporating 20 to 30% coarse sand improves soil structure and increases its drainage.

Installing perforated drainage pipes at a depth of 80 to 100 cm, spaced 8 to 10 meters apart, helps drain excess water during heavy rainfall. Another effective solution for improving surface drainage is to create mounds 30 to 40 cm high and 1 to 1.5 meters wide.

Using organic mulch 5 to 10 cm thick around trees helps maintain constant humidity while limiting evaporation. This technique also helps limit weed growth and protect the soil from erosion.

Finally, the installation of tensiometers at a depth of 30 and 60 cm allows the monitoring of soil moisture changes in real time and the adjustment of irrigation accordingly. A supply of approximately 1.1 mm per hectare per hour at a working pressure of 2.5 bars is recommended to ensure optimal watering.

Conclusion

Quince irrigation must be tailored to the specific needs of the crop and the soil conditions. Drip irrigation is the most efficient method, ensuring a precise and regular supply of water while also allowing for fertigation. Optimized irrigation management, combined with good drainage, helps improve fruit quality, limit losses, and ensure the sustainability of the orchard.
