How to increase the yield of blueberries

Blueberry is a kind of shrub fruit, is a new type of fruit introduced from foreign countries in recent years, its nutritional value in the fruit occupies a large weight, no matter men and women, young and old like to eat, but also very suitable for eating, but the current annual output of blueberries are limited, so far can not meet the needs of the market, the price is very expensive, so today by the pro-agricultural network to teach you how to improve the output of blueberries.

1. Select improved varieties

There are many varieties of blueberries, including dwarf blueberries and tall blueberries, some suitable for growing in shady areas and some suitable for growing in warm areas. at present, there are more than 20 varieties of blueberries, so they are various. among them, rabbit eye blueberry field is the easiest to feed, O'Neill is also a very good variety, especially suitable for growing in the south of our country, and there are some blueberries suitable for planting in the north. The editor will not cite examples here one by one. Choosing the right variety is the most basic way to increase the yield of blueberries. the second is to suggest that it is best to plant multiple varieties when planting, so that the yield and quality will be better.

2. Sowing seeds at the right time

Blueberry planting is a suitable time, can not be planted casually, our most common planting time will be in the autumn from the end of August to September, the survival rate of planting will be much higher, at the same time suitable for blueberry growth and development. Of course, you can also plant in spring, but preferably in early spring, so that blueberry wine can take root and sprout in this season and keep up with the pace when it is flowering and fruiting.

3. Fertilizer and water management

After blueberry planting, we need to carry out reasonable fertilizer and water management according to the nature of the soil planted. There are certain differences in fertilizer and water management in each growth period, and there are also differences in the management of each variety. Under normal circumstances, two fertilizers are needed in the seedling stage, and the taller blueberries need to be topdressing by digging trenches, while the shorter ones only need to be spread, and each time is mainly farm manure or organic fertilizer. Wait until after the blueberry results, and then on the basis of these two fertilizers, mainly foliar fertilizer, used to promote the growth of fruit. Foliar fertilizer needs to be sprayed almost once a year every two or three months, so that blueberry seedlings can grow better and avoid premature aging and yield reduction.

4. Field management

First of all, field management needs to talk about the pollination of blueberry planting, each plant must be planted in a four-to-one pattern, which can increase the probability of pollination and improve the fruit setting rate. The second is to thinning the blueberry seedlings in the field, remove the weaker branches and leaves, it will grow new branches, wait until a certain number of years, need to cut off all the old branches, let it send out new branches, which means new life. Then, it is necessary to keep the seedlings warm every winter, otherwise the blueberry seedlings will be frostbitten, and the flowering period needs to be controlled and the fruit will be controlled after falling. The way of controlling flowers and fruits is based on the principle of keeping good and large ones. Finally, it is necessary to clean up the fields, such as weeds, sundries, fallen leaves, dead branches, etc., and burn them to ashes with fire to avoid virus infection.

5. Artificial pollination

Artificial pollination is also a way to increase yield, but it will not be used under normal circumstances. We are more inclined to match pollination trees well. When the weather is relatively stable, the success rate of pollination is very high. Of course, we do not rule out some other cases, so we need to use the method of artificial pollination. First, we can also use external forces, such as putting colonies into the garden to carry out bee pollination. Or carry out pollen collection for pollination, and finally, you can directly pick the male flowers and then smear the male flowers on the female flowers and then cover the female flowers with male flowers for pollination. These are some methods of artificial pollination, which can also be used when necessary, which is also of great help to increase the yield of blueberries.
