What is the best variety of blueberry seedlings? What are the methods of raising seedlings?

Blueberry is a kind of fruit that many people feel sour when they hear it, but in fact, many varieties of blueberries are not only not sour, but also very rich in taste. Friends who want to grow blueberries should also consider the choice of varieties.

What kind of blueberry seedlings is good?

Blueberry varieties can be divided into four categories:

1. Dwarf clump

Dwarf blueberry alias wild blueberry, wild dwarf blueberry. It grows in only a handful of areas along the east coast of the Atlantic Ocean at high latitudes and low temperatures. Blueberry is a perennial woody rare fruit tree, which is listed as one of the five major health foods by the International Food and Agriculture Organization (FAO). It can be called "king of fruits in the world" and "golden fruit".

two。 Half-height bundle

Half-height blueberries are derived from the cross between northern high-bush blueberries and dwarf blueberries in the United States and other places. This species combines the characteristics of dwarf blueberry plant, strong cold resistance and high blueberry fruit quality. generally, the tree height is 50~100cm, and the fruit is larger than dwarf blueberry, but smaller than tall blueberry, strong cold resistance, and generally resistant to-35 ℃.

3. High bundle

High bush blueberry mainly comes from wild species of corymbose blueberry (Vaccinium corymbosum L.) Selection, breeding and hybrids of. Naturally distributed in North America. It is not resistant to drought and is suitable for growing on moist soil, and communities are often formed in swamps, streams, wet sandy lands and places with groundwater leakage in the foothills.

4. Rabbit eye blueberry

Rabbit-eyed blueberries are tall, long-lived and strong. Leaves broadly elliptic to ovate. The flower is light pink to fresh pink, and it is a cultivated variety selected from wild rabbit eye blueberry varieties. Before the fruit is ripe, its color is as red as rabbit eye, so it is named rabbit eye blueberry. The fruit of wild species is black or dark black, weighs about 0.5g, thin and tasteless, and the quality is poor. The fruit weight of the cultivated type is more than 1g, juicy and fragrant, with good flavor, and some of them are even better than high-clump blueberries.

2. The method of raising blueberry seedlings

1. Seedling site selection

Blueberry has certain requirements on the planting land, generally speaking, it will choose the soil with rich soil organic matter and soil pH of 4.0-5.5, and the drainage and irrigation system near the planting site is perfect, transportation is developed, and it is far away from pollution sources. Dig deep into the soil, the clods should be fine and the impurities in the seedlings should be cleaned up. Finally, before raising seedlings, we also need to configure the substrate for raising seedlings and apply basic fertilizer.

two。 Seedling raising time

The time of raising seedlings is usually in the spring every year, when blueberries are most vigorous, so the emergence rate and survival rate will be much higher. The best time to raise seedlings in spring is between February and April every year. Of course, when raising seedlings, the soil temperature of the planting site had better be ten degrees or above, otherwise the rate of germination will be very slow.

3. Seedling raising method

There are generally four methods to raise blueberry seedlings, which are seed propagation, cutting propagation, ramet propagation and grafting propagation. At present, the most commonly used methods are seed breeding and cutting jade seedlings, the survival rate of these two kinds will be higher, and the quality of blueberries is high. The seeds need to be treated with variable temperature and soaked with gibberellin to improve the germination rate of seeds. Cutting seedling is to select the strong branches of excellent varieties without diseases and insect pests, and then cut into sections five or six centimeters long, and then use a press to deal with the fracture to raise seedlings. In addition, ramet propagation is generally based on the selection of new plants from the mother plant, dug up at the end of autumn, and cultivated, and planted in spring. The grafting of blueberries is the same as that of other fruit trees, with a good choice of drilled wood and scions.

4. Seedling stage management

After raising seedlings, watering should be carried out frequently to maintain soil moisture and promote the growth of blueberry roots and new seedlings. But the amount of water should not be too large, if the temperature of the seedling land is high, then we need to wait for the temperature to drop before watering, otherwise it will affect the growth of blueberry seedlings. What we should also pay attention to is that in May and June, we should pay more attention to water management. The management of nutrients is also very important at the seedling stage. In general, we cannot apply fertilizer casually. If we promote the growth of seedlings in the future, it is best to apply an appropriate amount of liquid fertilizer once a week. At the same time, seagulls should be combined with watering during fertilization.

To sum up, it is the management of blueberry seedling stage. Do you have any favorite blueberries in mind? you can talk about the blueberry varieties that you think are good.
