How to increase the planting yield of blueberries?

Blueberry is a kind of shrub fruit and a new type of fruit introduced from foreign countries in recent years, but at present, the annual output of blueberries is limited, so it is far from meeting the demand of the market, and the price is very expensive, so how to increase the production of blueberries?

I. selection of improved varieties

There are many varieties of blueberries, there are bushes blueberries and high bushes blueberries, there are suitable meat donkey seedling price how much? Those growing in cool areas are also suitable for growing in warm areas. at present, there are more than 20 varieties of blueberries, so there are a variety of varieties, among which the rabbit eye blueberry field is the easiest to feed, and O'Neill is also a very good breed. It is especially suitable for planting in the south of our country.

Second, sowing seeds at the right time

Blueberry planting is a suitable time, can not be planted casually, the most common planting time will be in autumn from the end of August to September, the survival rate of planting will be much higher, at the same time suitable for the growth and development of blueberries, of course, can also be planted in spring, but preferably in early spring, so that blueberry wine can take root and sprout in this season.

III. Fertilizer and water management

After blueberry planting, it is necessary 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 spread fertilizer, mainly farm manure or organic fertilizer each time. Wait until after the blueberry results and then apply it again on the basis of these two rounds of fertilization, mainly foliar fertilizer, which is mainly used to promote fruit growth. Foliar fertilizer is needed to be sprayed almost once a year every two or three months, so that blueberry seedlings can grow better and avoid aging and reducing production ahead of time.

IV. Field management

Each plant must be planted according to a four-to-one model, which can increase the probability of pollination and increase the fruit setting rate. it is necessary to sparse the blueberry seedlings in the field, remove the weaker branches and leaves, and grow new branches. after a certain number of years, it is necessary to cut off all the old branches and send out new branches, which means that the seedlings need to be warmed every winter, otherwise the blueberry seedlings will be frostbitten. Flowering requires flower control and fruit control after flowering. The way of flower control and fruit control is based on the principle of keeping good and large ones. Weeds, sundries, fallen leaves and withered branches need to be cleaned up and incinerated into ashes to avoid virus infection.

5. Artificial pollination

Artificial pollination is also a way to increase yield, but it is generally not used, and it is more inclined to match pollination trees well. the success rate of pollination is very high when the weather is relatively stable, of course, some other cases are not ruled out. therefore, we need to use the method of artificial pollination, or we can also borrow external forces, such as putting bees into the garden to carry out bee pollination, or collecting pollen for pollination. You can also pick male flowers directly, then apply the pollen of male flowers to female flowers and cover them with male flowers for pollination. These are some artificial pollination methods, which can also be used if necessary. It is also of great help to increase the yield of blueberries.
