The latest course of cultivation techniques and methods of blueberry

Blueberry is a plant of the rhododendron family. Despite the fact that it is watered with blueberries, its shape does not bear any resemblance to ordinary oranges. The fruit of blueberry is crisp, delicious and juicy, containing a variety of nutrients needed by the human body. And the leaves of blueberry can also be dried into tea, which has a certain medicinal value. So how to grow blueberries now? Today, the editor has brought you the cultivation techniques of blueberries. Let's take a look.

1. Land selection and preparation

Blueberry is suitable to live in acidic soil, and the yield is obviously increased in the soil with high fertility, loose and deep soil and rich in organic humus. Planting plots need to have sufficient water, and leeward to the sun, to pay attention to the number of trees around, too many trees will block the sun of blueberries, affecting the growth of blueberries. After selecting the land, the roots of the previous crops in the soil should be removed in time to reduce germs. And in order to ensure the normal growth of blueberry, it is necessary to clean up the weeds before planting, and then apply sufficient base fertilizer before sowing.

2. Timely planting

After the land selection and preparation work is done, it should be planted in time according to the changes of the weather, and the planting density should be controlled. in order to ensure the yield of blueberry, it can be planted densely properly. Generally speaking, it is the best planting time before and after the Beginning of Spring every year, which can ensure sufficient water in winter, so it can also be planted in autumn and winter. When planting backfill soil, an appropriate amount of bark, sawdust and other substances should be added to the soil to improve soil fertility. And pay attention to improve the acidity of the soil, if the acidity is not enough, you can add a small amount of sulfur sulfonic acid to the soil.

3. Topdressing in time

The demand for fertilizer for blueberry is not very large, moderate or so, too much fertilizer not only can not promote the growth of blueberry, but also will have a certain impact. In particular, the seedlings after planting should not apply nitrogen fertilizer, because the seedlings are very sensitive to nitrogen fertilizer. Therefore, we should apply as little fertilizer as possible in the first year of planting, even if the base fertilizer is sufficient. When the soil fertility is large and the soil PH value is suitable, a small amount of nitrogen fertilizer can be applied, but nitrate nitrogen fertilizer can not be used. It should be noted that no matter when fertilizer is applied, fertilizer should not be applied directly to the roots of blueberries to prevent them from burning out.

4. Shaping and pruning

After planting, the shaping and pruning work should be done in time according to the growth of blueberry. In order to promote the development of young blueberry trees, the flower buds should be erased in time in about 1-2 years. Then the next year can start to leave fruit, but to pay attention to the number of fruit, not too much, otherwise the tree can not bear, resulting in fruit drop. And cut off the lower horizontal growth branches, dead branches, old branches and other useless branches. These branches not only fail to bear fruit, but also consume too much nutrition and increase the cost of planting.
