After planting, it needs to carry out a series of strip field management, which is related to yield and quality. So how should blueberries be managed in the field? Let's take a look at the detailed introduction.

1. Fertilization management

Blueberries have a low demand for fertilizer. In the case of fertile soil and high organic matter content, there is generally no need to apply nitrogen fertilizer or less nitrogen fertilizer. It is necessary to apply water-deficient elements according to the soil and leaf conditions. Organic fertilizer is applied once as base fertilizer after autumn defoliation, and the fertilizer amount is determined according to the size of the tree body. The fertilizer is spread in the range of 30-40 cm in diameter around the tree and covered with soil. After planting, it is necessary to cover the soil with organic fertilizer, which can not only increase the organic matter of the soil, but also keep the soil moist. In summer, it is necessary to reduce the ground temperature and protect the root system in winter.

2. Water management

Pay attention to ponding in the planting process. Ridging will be carried out before planting. The ridge surface should be about 20 ridges higher than the ground to prevent ponding. Water immediately after planting to keep the soil moist and improve the survival rate. Water once every 2-3 days, about 1-1.5 kg each time. In case of drought, water once in time to avoid drought damage. In rainy season, pay attention to drainage and waterlogging prevention.

3. Pruning

In the year of planting, thin branches and pests should be pruned off, one is to consume nutrients for thin branches, concentrate nutrients and healthy branches, and the other is to prevent the spread of pests. When the plant enters the fruiting period, pay attention to the number of fruits. At this time, the nutrients in the tree body are not enough to supply more fruit growth and development. At the same time, the branches that grow vigorously should be cut off and its height should be controlled. For dense fruiting branches, the flower buds of the whole plant should be kept at about 50%. It is best to prune during the dormant period of the plant. In addition, after pruning, the garden should be cleaned up in time, the weeds in the garden should be cleaned up, and then the dead leaves and pruned branches and leaves should be burned in time.

4. Pest control
