What are the requirements for growing blueberries? What is there to pay attention to? Please introduce the following points for reference when planting blueberries: first, the soil requirements of blueberries: according to the ecological adaptability of blueberries, first determine the suitable planting area (that is, the area with suitable climatic conditions), and then select the planting plot. When selecting planting plots, we should first understand or determine the soil pH;. Secondly, we should choose the places with loose soil, rich organic matter and good drainage and irrigation conditions as far as possible. If the mountain area should choose the middle and lower part of the sunny slope as far as possible, the slope should not exceed 15 °, and the terrace with a width of 2m should be built when the slope is greater than 15 °. However, the survival rate of returned farmland is not as high as that of pine forest, and there are more diseases, insect pests and weeds than pine forest, which increases the cost of production and management. In the southern hilly and mountainous areas, combined with the construction of commercial forest bases, popularizing the planting of blueberries can not only improve the ecological environment, but also adjust the forest structure, but also increase the economic income of the people in the mountain areas. 2. Planting density and land leveling of blueberries: 1.0 × 1.5 m × 2.0 × 3.0 m for alpine blueberries, 1.5 m × 2 × 2.5 m for rabbit eyes blueberries and 0.6 × 1.2 × 2 m for half-height blueberries. In foreign countries, the actual cultivation density often depends on the degree of mechanization. In the south and north of our country, we can choose the appropriate density according to the actual business objectives. Digging the planting hole before planting is called soil preparation, and the specification of soil preparation (planting hole) is 1.0m (length) × 1.0m (width) × 0.5m (depth). Planting half-height blueberries and dwarf blueberries can appropriately reduce the size of soil preparation, while blueberries with rabbit eyes can appropriately increase the size of soil preparation. After the planting hole is dug, the soil taken out is mixed with ground pine bark, peat or humus soil under the pine forest, mixed evenly and then backfilled into the hole, the backfill soil should be higher than the 20~30cm of the ground, and an appropriate amount of sulfur powder can be mixed in the case of insufficient soil acidity. 3. Selection of blueberry varieties and planting time: cross-pollination is one of the important factors to increase blueberry yield and fruit size. High-clump blueberry has high self-fruiting rate, while dwarf blueberry and rabbit-eye blueberry have very low or unfruiting rate. Cross-pollination can increase the fruit setting rate of high bushes blueberries from 67% to 82% and rabbit eye blueberries by 47% from 18%. Therefore, in the blueberry seed value garden, at least two or more varieties should be pollinated with each other in order to improve the yield and quality. The allocation ratio of pollination trees is generally 2 lines 3 lines for main cultivars and 1 row for pollination varieties. Blueberries are best planted from autumn to early spring in the south, which is not very dry in winter. The planting depth of one-year-old seedlings is 15~20cm, and it is necessary to help the soil to be compacted so as to achieve "three supports, two steps and one lift". It is suitable to be planted in dry places in autumn and winter when the rainy season comes, and in places with irrigation conditions, it can be planted all the year round. Summer colonization in Majang, Guizhou, can also achieve a survival rate of more than 95%. Click to get more strawberry planting techniques click to get more fruit planting techniques
