Blueberry trees blossom and bear fruit for several years

Generally, artificially cultivated blueberry trees can blossom and bear fruit in the second year, but the yield is relatively small, and they can enter the high yield period in the fifth year. So how do you grow blueberries to be productive? The following points must be remembered.

High-yielding techniques of blueberry planting

1. soil

The pH value of the soil is controlled between 3.9-5.0, and the organic matter content is in the range of 5%-15%; too high pH will cause poor iron deficiency growth, which will lead to seedling death seriously; when the pH value is greater than 5.5, sulfur powder or aluminum sulfate should be used. If you buy three-year and five-year-old blueberry seedlings, you should control the pH value one year in advance.

2. planting density

The planting density of blueberry depends on the variety planted. Generally, the planting density of high-bush blueberry is 1.2-1.5 meters, and the row spacing is 2.5-3.5 meters. The planting density of rabbit-eye blueberry is 1.5- 2.5m, row spacing is 3.5- 4.5m. The planting density of dwarf bush blueberry is 0.5-1 m X 1 m. In practice, planting density can be adjusted according to specific planting varieties, plant size, soil fertility and management level.

3. planting time

Blueberry field seedlings are suitable for planting in spring and autumn, and it is best to plant in spring in northern areas. If they are planted in autumn and improperly managed in winter, they are easy to be frozen. Spring planting should be done before spring germination. Southern areas can be planted in autumn, generally in November to December when growth stops and dormancy enters.

4. water and fertilizer management

High-bush blueberries were treated twice with organic fertilizer in the form of furrow fertilizer. After the second year of planting, the leaves were sprayed with integrated iron solution and borax solution. Blueberry irrigation needs to pay attention to water source and water quality, deep well water generally pH value is high, and sodium and calcium content is high, long-term use will affect blueberry growth and yield, can be adjusted to pH value 4.5~5.5 with sulfuric acid when irrigation, but should be about 3 times irrigation and irrigation acid water.

In addition, timely weeding, pruning and thinning flowers and fruits are also effective means to improve blueberry yield, growers must pay attention to oh.
