First, seedling selection
Planting blueberry trees should choose varieties with high yield, less pests and diseases and large fruit grains, and the tree age should be more than two or three years. We should ensure that the root system is strong and vigorous, so that blueberry seedlings can resume growth faster after planting.
Second, the configuration of soil.
Blueberries like soft and breathable weak acid soil, so pay attention to the soil used. If it is a potted plant, it is recommended to mix peat soil, humus soil and sand, as long as the flowerpot size is appropriate. If you plant it in the ground, you must first apply chemical fertilizer and farmland to ensure that the land is soft and fertile.
Third, the planting method
When planting, a suitable pit should be dug according to the size of blueberry seedlings, then the seedlings should be placed in into the pit to ensure that their roots protrude, and then the soil should be slowly filled and compacted. After planting, it should be watered in time, so that the seedlings can absorb enough water, so that the root system can be more closely combined with the soil, and it can resume growth as soon as possible.
Fourth, fertilizer and water management.
Blueberries like humid environment and are drought-tolerant. Don't water it when it is dry, but water it in time when it is dry. Moisturizing in spring and autumn is enough, and the temperature is high in summer. It is necessary to increase the number of watering properly and ventilate frequently. The temperature is low in winter, so it is enough to water the wintering water once in advance after winter. In addition, it is necessary to fertilize frequently in the peak season to ensure adequate nutrients. Fertilizers are mainly selected from decomposed farmyard manure.
Growth habit
Different varieties of blueberry have great differences in fruit size, quality, fruit yield and fruit storage. Blueberries in the north high cluster have large particles and the best fruit quality; Rabbit eye blueberry is medium to large. The sugar-acid ratio of mature fruits varies with different kinds, some are sweet, some are sour, and some are moderate in sweetness and sourness.
The ratio of sugar to acid is one of the criteria to measure the fruit quality of blueberry varieties. Generally speaking, the high-bush blueberry is earlier, and the rabbit-eye blueberry is later; Among the high-cluster blueberries, the northern high-cluster blueberries are mostly early-maturing and mid-late-maturing varieties; Late-maturing varieties account for the majority of southern high-bush blueberries.
