Orchards should be selected in areas with inconvenient transportation and irrigation. Planting holes can be directly dug in flat land and gentle slope land, and the specifications of planting holes are generally 60cm×60cm×40cm. When applying base fertilizer, the soil taken out will be mixed with decomposed sawdust, humus soil under pine forest or decomposed manure. And then evenly mixed and backfilled into human body holes.
2. Planting requirements
Choose 1~2-year-old seedlings with plant height of more than 30cm and diameter of main stem base of more than 5mm, and advocate the use of container seedlings. It requires strong plants, developed roots and no obvious harm. At least two varieties of the same type with the same flowering period should be planted in the same plot to facilitate cross-pollination, and the variety allocation ratio is generally 1: 1 or 1:2 or 1:3.
Bare-rooted seedlings should be planted from June 165438+ 10 to the end of February of the following year; Container seedlings can be planted in any season, especially during dormancy. According to the land conditions, the planting density is determined, and the spacing between rabbit eyes is1.6 ~1.7m× 2.0m. The row spacing of high-cluster varieties is1.2m× 2.0m. When planting, the roots should be stretched and the seedlings should be upright. While covering the soil, the seedlings should be gently lifted upwards, and the soil should be covered and compacted to make the roots in close contact with the soil. When the seedlings are in nursery or container, the planting depth is slightly 2 ~ 3 cm higher than the original soil standard.
3. Tian Tuan management
Intertillage weeding: according to the occurrence of weeds in the field, intertillage is 3~4 times a year, and the depth of intertillage is about 5cm. Improve the soil structure and keep the soil loose and breathable.
Water management: The characteristics of blueberries in water can be summarized as drought resistance, water preference and fear of waterlogging. Blueberries have strong drought resistance, but because the root system is shallow, excessive drought will affect their growth, so adequate water is very important for blueberries. But too much water can also cause blueberry root rot. If it is sunny in summer, water it every one or two days.
Fertilization principle: to fully meet the requirements of blueberry growth and fruit for various nutrients, apply organic fertilizer, and prohibit the use of chlorine-containing fertilizers and chicken manure. Commonly used fertilizers include biogas slurry fertilizer, green manure, cake fertilizer, compost, compost and manure.
4, plastic pruning
Young trees are mainly cultivated. During this period, flower buds should be erased, weak branches should be thinned and nutrient consumption should be reduced. In the growing season, the new shoots of young trees are cored about 40cm to increase the number of lateral branches and rapidly expand the crown width. For 3~4-year-old fruit trees, the weak branches in the lower part and the crowded clustered branches in the middle of the crown are mainly removed. For the main branches that bear fruit for more than 5 years, they should be retracted in time on the plants with general tree potential; On plants with strong tree potential, it can be cut off from the base of the main branch.
5, pest control
Generally, there is no disease or serious disease in the new planting area, and the pests mainly include poisonous moths, thorn moths and other pests adjacent to the orchard, such as peach fruit borers and longicorn beetles. Therefore, small isolated gardens can be used in southern mountainous areas to reduce the degree of harm.

Therefore, small isolated gardens can be used in southern mountainous areas to reduce the degree of harm.
6, timely harvest
Dwarf blueberries have the same maturity, and the early-maturing fruits are not easy to fall off, so they can be harvested together after all the fruits are ripe. After the fruit is harvested, the dead branches, fallen leaves, stones and other sundries are removed and put into a container. The ripening period of high-cluster blueberry fruit is different, and it usually takes 20 ~ 30 days to harvest, usually once a week/kloc-0. Fruit should be picked manually when it is fresh and harvested mechanically when it is used for processing.
