The Latest Technical Methods and Tutorial for Blueberry Field Management

Blueberries have a unique flavor, come in many varieties, and are highly nutritious, making them very popular with consumers. After planting, a series of field management tasks are needed, and these affect both yield and quality. So how should blueberries be managed in the field? Let's take a look at the detailed introduction below.

1. Fertilization Management

Blueberries have a relatively low demand for fertilizer. In soil that is fertile and high in organic matter, there is generally no need to apply nitrogen fertilizer, or only a small amount. Just apply the deficient elements as a top dressing according to soil and leaf conditions. After leaf fall in autumn, apply organic fertilizer once as a base fertilizer; the amount applied depends on the size of the tree. Spread the fertilizer in a 30-40 cm diameter range around the tree, then cover it with soil. After planting, the soil should be covered with organic fertilizer, which can both increase the soil's organic matter and keep the soil moist. In summer it helps lower soil temperature, and in winter it protects the root system.

2. Water Management

During the growing process, pay attention to waterlogging. Before planting, ridges are made, and the ridge surface should be about 20 above ground level to prevent water accumulation. Water immediately after planting to keep the soil moist and improve the survival rate. After that, water once every 2-3 days, about 1-1.5 kg each time. During drought, replenish with an additional watering in time to avoid drought damage, and during the rainy season also pay attention to drainage to prevent waterlogging.

3. Pruning and Branch Training

In the year of planting, prune away weak-growing branches and branches affected by pests or diseases. First, this is to prevent weak branches from consuming nutrients so that nutrients are concentrated in vigorous branches; second, it is to stop the spread of pests and diseases. When the plant enters the fruiting stage, pay attention to the number of fruits; at this time the tree's nutrients are not enough to supply the growth and development of too many fruits. At the same time, branches growing vigorously should be cut back to control their height, and densely set fruit-bearing branches should be pruned, keeping about 50% of the flower buds in the whole plant. Pruning is best done during the plant's dormant period. In addition, after pruning, immediately clean the orchard once, remove weeds from the orchard completely, and promptly burn the dead branches and fallen leaves as well as the pruned branches and leaves.

4. Pest and Disease Control

Throughout the entire growth period, blueberries have many pests and diseases. Common ones include leaf spot disease, canker disease, root rot, as well as white grubs, stinging nettle caterpillars, and others. Therefore, targeted preventive and control measures should be taken according to their occurrence patterns. For pests, black light traps and manual catching can be used.
