Field management technology of blueberry

Blueberry taste is unique, fully numerous, high nutritional value, favored by consumers, after planting the need for a series of field management, which is related to yield and quality. So how to manage blueberries in the field? Let's take a look at the detailed introduction.

1. Fertilization management

Blueberry demand for fertilizer is relatively low, in the case of fertile soil and high content of organic matter, it is generally not necessary to apply nitrogen fertilizer or less nitrogen fertilizer, but to apply water-deficient elements according to the condition of soil and leaves. After defoliation in autumn, one organic fertilizer was applied as the base fertilizer. According to the size of the tree, the fertilizer was sprinkled in the range of 30-40 cm in diameter around the tree and covered with soil. After planting, it is necessary to make soil cover organic fertilizer, which can not only increase soil organic matter, but also keep soil moist, reduce soil temperature in summer and protect root system in winter.

2. Water management

In the process of planting, we should pay attention to stagnant water, ridging will be carried out before planting, and the ridge surface should be about 20 ridges above the ground to prevent stagnant water. Watering immediately after planting, keep the soil moist, improve the survival rate, and then water every 2-3 days, about 1-1.5 kg each time, make up watering in time during drought to avoid drought damage, and pay attention to drainage and waterlogging prevention during the rainy season.

3. Pruning

In the year of planting, it is necessary to prune the branches of thin growth and insect pests, one is to consume nutrients and concentrate nutrients and strong branches, and the other is to prevent the spread of diseases and insect pests. When the plant enters the fruiting stage, we should pay attention to the number of fruit, when the tree nutrients are not enough to supply more fruit growth and development, at the same time, the vigorous branches should be cut, its height should be controlled, and the dense fruiting branches should be pruned. The flower buds of the whole plant should be retained at about 50%, and pruning should be carried out during the dormant period of the plant. In addition, the garden should be cleared in time after pruning, the weeds in the garden should be removed, and then the litter and pruned branches and leaves should be burned in time.

4. Pest control

There are many diseases and insect pests in the whole growth period of blueberry, such as leaf spot, canker, root rot, grubs, diamondback moth and so on, so it is necessary to take targeted prevention and control measures according to its occurrence regularity. black light trapping and artificial trapping can be used for pests.
