The blueberry planting season is March-April in the spring, and in the mountainous areas of the south, the fall planting season is September-December and February-March of the following year. Spring planting seedlings need to go through a period of slow seedling, fall planting is conducive to the seedling root system to speed up the recovery, the following spring can be rapid growth, and then after 12 months or so will be able to bear fruit.
When to plant blueberries
1, planting season
(1) The planting season of blueberries varies from place to place, if planted in the northern region (north of the Yellow River), the appropriate time for the spring in March-April, if planted in the mountainous areas of the south, the appropriate season for the fall in September-December, the following year in February-March.
(2) If planted in the spring, the seedlings need to go through a certain period of slow seedling, if planted in the fall, it is conducive to accelerate the recovery of the seedling root system, the next spring plants can grow rapidly, and then after about 1 year can be fruit.
Blueberry planting method
1, planting soil
Planting the whole garden in the fall of the year before the first land deep turning 40 ~ 60cm above, digging a good drainage ditch, gentle slope into a gentle slope, after the sprinkling of powdered sulfur, the specific dosage needs to be determined according to the determination of the soil pH status to determine the dosage to ensure that the uniformity of two times! Spreading rotary plowing. Park rotary tillage deep turning, again before rotary tillage per mu material input amount is: about 5 square of charcoal, organic fertilizer about 3 tons, sawdust or diameter of 3 ~ 5cm size of the bark cover thickness of 5 ~ 10cm, 30-50 square per acre.
2, planting method
Digging planting holes on the ridge when planting, the size of the general 40 × 40 × 40cm or so. The bottom plus organic fertilizer 5kg, compound fertilizer 30~50g to do the bottom fertilizer, after joining more mixing soil mix, stay in the bottom layer. Cover a layer of soil, and then add some charcoal, insecticides and soil mixed with the soil mix to stay in the upper layer of the planting hole, ready for planting.
Planting in advance of the nutrient potting seedlings into the water soaked through, removed from the pot, slightly shaking off the root system, has been dug on the planting hole and then dug a small pit about 20cm × 20cm, the seedlings planted, gently stamped, watered thoroughly. Covered with pine needles, rice straw, sawdust and other moisturizing acid, covering 15~30cm above the ground is appropriate.
3, control temperature
Long in the blueberry planting technology, blueberry flowering and fruiting need to carry out cold storage, that is, to control the growth temperature below 5 ℃; in the comfortable temperature of the south, when the cold storage is not up to standard, blueberry will only flower and not fruiting, in the Yangtze River Basin near the planting of blueberries, the winter season, do not need to move it indoors.
4, fertilization treatment
Blueberry in the growth, do not like fertilizer, in the early planting, the soil can be added to the appropriate humus soil, will be able to meet the nutrients of plant growth; in the plant fruiting period, the need to use diluted nitrogen fertilizer, fertilizer fertilizer can not be to get to the stem of the blueberry; when blueberries fruiting, and then a diluted nitrogen fertilizer to help over winter.
5, watering times
Blueberry root system belongs to the floating root, that is, the root is very close to the soil surface, so the amount of water in watering can not be too much; but the blueberry is a water-loving plants, so the soil surface can be generally wetting, watering can be mixed with the appropriate white vinegar, watering once a week.
