Expert Tips To Meet Blueberry's Water Requirement

November 01,2021

Many agriculture now adopt sprinkler irrigation to improve irrigation efficiency. Your large blueberry garden needs agriculture machinery equipment to better grow blueberries, because adequate water sources and irrigation conditions are the key to successful blueberry cultivation.

Water requirement

Proper soil moisture is necessary for the growth of blueberries, and insufficient moisture will seriously affect the growth and yield of the tree. From germination to deciduous leaves, the water required for blueberries is equivalent to an average weekly precipitation of 25mm, and from fruit setting to fruit harvesting is 40mm. The annual rainfall is large and evenly distributed, and the natural rainfall can basically meet the requirements of blueberry growth. But most places should be equipped with irrigation facilities. Commonly used irrigation methods include furrow irrigation, sprinkler irrigation, drip irrigation and other irrigation methods. Consult the blueberry irrigation system exporter for more specific irrigation methods.

 

How to determine the watering time of blueberries

Irrigation must be carried out before the plants wilt. The irrigation time and quantity should be determined according to the type of soil. Sandy soil has weak water holding capacity and is prone to drought, so it needs frequent inspection and irrigation. Soils with high organic matter content have strong water holding capacity, and the frequency of irrigation can be appropriately reduced. Judging whether to irrigate or not can be judged based on field experience, that is, shovel a certain depth of soil sample with soil.

 

If the soil ball in the sampled soil is squeezed and easily broken, it means that it has been dry. A rough judgment can also be made according to the monthly precipitation during the growing season and the precipitation required for the growth of blueberries. When the rainfall is lower than the normal rainfall of 2.5-5mm, it may cause blueberry drought and need to be irrigated.

 

Common methods of blueberry irrigation

The common method of blueberry irrigation is to choose a mobile or fixed sprinkler irrigation system. In addition to irrigation during the growing season, sprinkler irrigation can also be used to prevent or reduce frost damage. In the newly-built orchard, the newly planted seedlings have not yet developed and the absorption capacity is poor, so sprinkler irrigation is the most suitable method. In large blueberry producing areas in the United States, mobile rain gun sprinkler irrigation system wholesalers are often used to provide sprinkler irrigation.

 

Drip irrigation and micro sprinkler irrigation

Drip irrigation and micro-sprinkler irrigation methods have been used more and more in recent years. The investment of these two irrigation methods is medium, the water supply time is long, and the water utilization rate is high. The supplied water is directly supplied to each tree, with less water loss, less evaporation, and uniform water supply.

 

Compared with other methods, drip irrigation and micro-sprinkler irrigation can better maintain soil moisture and prevent drought or excessive water supply. In addition, the drip irrigation system provides a more convenient method for fertilization, dissolving chemical fertilizers directly in the irrigation water, thereby improving the fertilization effect and reducing costs. Therefore, it can significantly increase yield and fruit weight compared to other irrigation methods.

 

Two issues should be paid attention to when using drip irrigation and micro-sprinkler irrigation. One is that the dripper or sprinkler should be located on both sides of the tree to ensure that the entire root system can obtain water. Affect production. Second, the irrigation water needs to be purified to avoid clogging of drip holes or nozzles.

 

In addition, you need to pay attention

Groundwater level

The main blueberry production area or wild distribution area is mainly located on sandy loam soil with underground habitat water. The groundwater level of such a soil must reach a sufficient height for the upper soil layer to have sufficient soil moisture. In order to achieve good drainage in the rainy season and meet the upper soil moisture, the soil's habitat water level should be 45-60cm. If the site conditions of the blueberry orchard meet the above requirements, a permanent observation well can be set up in the center of the blueberry orchard to monitor the soil water level.

 

Water source and water quality

The ideal water source is surface pond water or reservoir water. Deep well water tends to have high pH and high sodium and calcium ion content. Long-term use will affect the growth and yield of blueberries.

 

According to the above tips, adopt the correct blueberry irrigation system, such as mobile rain gun sprinkler irrigation system or other irrigation methods, to ensure the blueberry water demand.
