How to choose blueberry seeds? What are the methods of raising seedlings?

Blueberry is known as the "fruit queen", sour and sweet taste, unique flavor, but also rich in conventional and special nutrients, is one of the five healthy fruits recommended by the World Food and Agriculture Organization. At present, the price of blueberries on the market is very high, but it does not affect people's love for it. In recent years, more and more people are growing blueberries in their backyards. So how to choose the seeds when planting blueberries? What are the methods of raising seedlings? Let's take a look.

How to choose blueberry seeds?

First of all, in the selection and purchase, it is best to buy from local seed companies or seed enterprises, so you can rest assured that there are too many fake and shoddy seeds on the market, which must be registered and put on record. Secondly, before selecting seeds, it is necessary to determine their varieties and adjust measures to local conditions, such as the middle and lower reaches of the Yangtze River, whose soil is characterized by high stickiness. It is more suitable for planting Nanjin, rabbit eyes, emeralds and so on. After the variety is selected, you should choose those seeds with full grains, no damage and high germination rate, and pay attention to the instructions above to understand the habits and characteristics of the seeds.

What are the methods of raising seedlings?

In order to meet the market demand, the method of cutting seedlings is generally used in the process of blueberry planting, which is helpful to increase the planting yield and increase the planting income. The methods are as follows:

1. Insert selection

In the selection of cuttings, it is necessary to cut from the trees that are disease-free and robust. If diseases have occurred in the blueberry orchard, the length of cuttings should be guaranteed to be 15cm in the actual cuttings selection. In addition, the cutting branch had better be an annual vegetative branch.

2. Seedbed preparation

It can be cut directly in the field and laid into a substrate bed with 1 m width and 25cm thickness. At present, a more widely used and relatively inexpensive way is to use a wooden structure to make a wooden box with a width and height of 2 m, 1 m and 0.4 m respectively, and a hard board with a sieve hole of 0.4 m is nailed at the bottom of the wooden box. by keeping a certain distance between the wooden box and the ground through the use of the log frame, the rooting rate can be improved on the basis of increasing the temperature of the matrix.

3. Cuttage treatment

The specific way is to water the substrate to ensure that it is thoroughly watered and to control the specific amount of water. It is best to have no stagnant water while the humidity meets the requirements. After the moisture condition meets the requirements, the cutter is inserted vertically and downward, and the distance between the cuttings is controlled, usually 5cm.

4. Plug-in management

After completing the cutting work, it is necessary to water regularly and control the amount of water. After the cuttings took root, the cuttings were treated in a liquid way, fertilized every 7 days, sprayed in time after the completion of fertilization, and washed the fertilizer residue on the leaves to avoid damage to the leaves due to accumulation for a long time.

Generally speaking, in the actual process of planting blueberries, we must first make great efforts in seed selection, if the selection is not good, it will delay the ripening time, prolong the seedling growth cycle and increase the cost of blueberry planting. In addition, skillfully master the relevant skills of cutting seedlings to ensure the improvement and stability of yield.
