Blueberry varieties suitable for the north

Blueberry varieties suitable for planting in the north are Meidon, Swick, North Blue, Beicun, Zaolan, Jersey, Lanfeng, Darrow, Elliot and so on. Because of the cold climate in the north, it is necessary to select blueberry varieties with outstanding cold resistance, the most common of which are north alpine blueberries. The blueberry fruit produced by this type of variety is larger, the quality is strictly controlled, and the taste is more delicate.

Blueberry planting technology

I. Seedling selection

Two or three-year-old blueberry seedlings are the most suitable, which can bear fruit in a short time. The length of time in the process of seedling selection has a great impact on the cost calculation and growth cycle in the future. pay attention to avoid the seedlings of diseases and insect pests and only choose the seedlings that grow well.

II. Garden construction

Choose the position with smaller slope to maintain the development and absorption of blueberry roots, and the soil can be more acidic. The planting time of blueberries every year can be divided into spring and autumn. The survival rate of planting in autumn is higher than that in spring. Determining the height and spacing of stop planting according to different varieties can improve the fruit rate and yield.

III. Soil management

Generally speaking, the cleaning work can be started around August every year, and the longer the time drags on, it will be very disadvantageous to blueberries overwintering. The common methods are clean ploughing and grass growing. When weeding, we should pay attention to efficiency, so that nutrients can be really delivered to the needed roots. Weeding work done in place, can basically double the yield, soil mulching can also inhibit the wild growth of weeds.

IV. Fertilization

Blueberry is mainly nitrogen, phosphorus and potassium fertilizer, the proportion of nitrogen, phosphorus and potassium is 1:1:1, the application of nitrate nitrogen fertilizer is prohibited, and the application of chlorine fertilizer such as ammonium chloride is prohibited.

V. Irrigation

Mentioned earlier, blueberry root distribution is relatively shallow, like wet, so irrigation is very important, irrigation can not use high PH water, irrigation acid water, once every 3-5 days.
