(A) The right area to choose the right blueberry varieties
Blueberry is not just any place can be planted, choose the right variety of cultivation is also an important condition of high yield.
1. The northeast region to choose a strong cold resistance of semi-high irrigation blueberry group varieties and dwarf irrigation blueberry group varieties, such as the Canadian breeding Meden, Fenty and the United States was stopped, Kitamura and other varieties.
2. North China selects high irrigation blueberry group varieties, such as American medium-ripening varieties of Sharp Blue and early-ripening varieties of O'Neill, etc.
3. South of the Yangtze River basin can choose the southern high irrigation blueberry group varieties and rabbit-eye blueberry group varieties, if the grain is large early maturing species of thin fog, garden blue, powder blue and other excellent varieties bred in the United States.
4. South China choose rabbit-eye blueberry group varieties, such as late-maturing species Baldwin and the above-mentioned garden blue, powder blue are very good choices.
(B) Choose good blueberry seedlings
1. Generally want to get faster results can be used 2-3 years of seedlings, seedlings can not have weak growth, root system sparse and diseased plants, to choose a strong seedling.
2. If the seedlings are their own seedlings can choose to use the greenhouse seedlings, seedlings its to moderate watering every day, observe the disease and insects, timely prevention, after the root system grows full of nutrient bowl can be moved into the field.
(C) The construction of blueberry garden
1. Blueberry plantation soil is loose and fertile, aeration, moist and not waterlogged, rich in organic matter acidic ground. In the planting of blueberry seedlings money also in advance of the deep tilling of the land.

2. Blueberry planting can be selected in the spring and autumn, planting is to consider a good planting density, planting good blueberry to timely watering rooting water.
(D) The maintenance and management of blueberry
1. Blueberry root distribution is relatively shallow, so appropriate irrigation is very necessary, generally with a pH value of about 5 water for irrigation, every 3-5 days irrigation, of course, when there is a lot of rain does not need to irrigate, and also to talk about the excess water drainage.
2. Clear plowing and weeding are essential in the management process, generally the depth of the clear plowing should not be too deep, keep it at 5-10 cm is about the same, artificial weeding cost is too high, you can choose low drug damage, low pollution chemicals for.
3. Blueberry fertilizer application is generally carried out in early spring before budding and berry maturity, with nitrogen, phosphorus and potassium compound fertilizer, ammonium sulfate, etc., fertilization should be based on the soil and growth conditions to determine the amount of fertilizer, too much fertilizer is easy to cause the death of blueberry seedlings.
4. Blueberry in the second year after planting to prune out the weak, diseased branches, adult blueberry seedlings to control the height of the tree, cut off excess branches and leaves, leaving large branches and medium branches, Hualiang large is able to food therapy cut off part, to ensure that each strong branch has 2-4 buds on it; if the blueberry tree a pound planted more than twenty years, you can cut all the branches close to the ground, and so the base of the re-sprouting of new branches and leaves.
5. Generally the maturity of dwarf bush blueberry is more consistent, and can be harvested together after maturity; high bush blueberry maturity picking period can last 20-30 days, so the picking should be timely every week to avoid birds and insects picking blueberry fruit.
