Blueberry Pot Planting Technique
Potted blueberries have the advantages of viewing flowers and rewarding goods.
I. Buying time and management of potted blueberry seedlings
Potted seedlings can be planted throughout the year. The best time is to buy them from the fall to the second year before the spring sprout. This period of seedlings is easy to transport, and management and planting are relatively simple. After the autumn planting, the second year can be a small amount of flowering, a small number of results, the third year can be normal flowering results, full fruit period is the fifth year after the family potted blueberries, properly managed, the results can be maintained for 35 years.
First, Potted Blueberry Seedling Tree Species Selection
Rabbit eyes Blueberry, Sharpan, O'Neil self-pollination is not true, must be configured pollination tree in order to fully result, the family potted plant is not easy to choose this species, dwarf groves only suitable for northern open-sided planting, other species can be used for family potted plants.
Second, the soil requirements
Blueberry, hi acidic, soft, loose, breathable, organic-rich soil, generally requires the soil pH value of 4.5 to 5.5, soil organic matter content is generally 8% to 12%, the family potted plants can buy common humus soil, depending on their own Conditions, add oozing moss or peat, wood chips, decayed pine bark and other organic matter, add sulfur, once a month, until the leaves have a slight burn, fertilization should also pay attention to the application of acidic fertilizer, the key tips: blueberries are calcium plants, soil Do not add bone meal.
Fourth, container
It is recommended to use a breathable tile basin, followed by Yisha basin, followed by plastic basins. Ceramic or porcelain basins are not recommended. Because blueberries are fibrous roots, shallow roots, do not need to use large pots, avoid deep basin, pots recommended with 15cm pots pots, finished plants with 25cm pots can be bogey seedlings with large pots.
V. Climate conditions
A very important factor in guaranteeing the results of potted blueberries is to ensure that the blueberries in winter suffer from low temperature dormancy below 7.2°C, and the lowest temperature tolerate varies depending on the variety. For example, as a flower, it is not necessary to limit the temperature.
Sixth, watering management
Blueberry roots have a shallow distribution and are sensitive to water deficiency. They should always be kept moist and have no accumulation of water. There are also differences in the blueberry's different growing seasons. In the vegetative growth stage, the most suitable moisture condition can always be maintained to promote the plant's strength. Before the fruit development stage and fruit ripening, the water supply must be properly reduced to prevent excessive nutrient growth and fruit competition for nutrients. After the fruit is harvested, the recovery is the most. Suitable moisture supply promotes vegetative growth. From mid-Autumn to late-Autumn, the supply of water is reduced to facilitate the entry into dormancy. In order to maintain the acidity of the soil, it is recommended to use vinegar at 3 to 5 degrees and apply 500 ml per month, including half a spoonful of vinegar.
Seven, fertilization
Blueberry is an oligotrophic plant. Compared with other fruit trees, the content of nitrogen, phosphorus, potassium, calcium and magnesium in the tree is very low. Due to this feature, blueberries must be specially formulated to prevent overdose and avoid fertilizer damage. When blueberries are planted, soil has been incorporated into organic matter, so blueberry fertilization mainly refers to dressing. Suitable fertilizers for potted blueberries are phosphorus pentoxide and ammonium sulfate. Excessive application of blueberry can easily cause tree damage or even the death of the whole plant. Therefore, the amount of fertilization should be prudent, depending on the soil fertility and tree nutrient status, rather less not much! In addition, blueberry can not be applied nitrate fertilizer, such as: ammonia nitrate, potassium nitrate, etc.
Eight potted blueberry plastic trim
The period of pruning can be divided into winter pruning and summer pruning, strictly speaking dormant pruning and growing season pruning. Saplings that have just been planted need to have flower buds and excessively thin branches cut off. For strong branches, generally there are different degrees of short cuts. In the first growing season of planting and survival, try to cut as little or as little as possible to maximize the amount of canopy and branches. In the first three years of saplings, the saplings were mainly pruned in the lower part of the tree, drooping branches, horizontal branches, cross branches of the litchi in the crown, dense branches, overlapping branches and so on. It is possible to cut the flower buds on the top of the shoots with a slight short cut. After sprouting in the spring, some new shoots should be erased as soon as possible to enhance the growth potential of the new shoots. After entering the fruit period, the size of the canopy has basically reached the requirements. It should begin to control the further expansion of the crown, leaving the limited space for the more vigorous branches or branches. The principle is to stay weak. In addition to weak branches, diseased branches, dead branches, crossing branches, and overlapping branches close together are objects that need to be removed.
