Blueberry pelvis, which has the virtues of a flower-seeing and tasteful experience, is popular among the citizens, because blueberries are bushes, making it easy to cut out the ideal tree type, blueberry flowers, white and beautiful, and the sweet and sweet taste of fruit, and will certainly be an important product of the greening of people's homes. As the country matures in terms of blueberry tree plugs and grouping techniques, it is no longer a dream for flower growers
I. Time and management for the purchase of pellets of blueberries
Plantation trees are available four seasons a year, preferably in the period between autumn and the spring of the second year, when they are easily transported and managed and planted. After the fall planting, a small amount of flowers will be available in the second year, with a small number of results, a normal flowering in the third year, and after the fifth year, a family pellets of blueberries will be properly managed and the outcome period will be maintained for 35 years。
Ii. Selection of plant-planted blueberry tree species
Blueberry rabbits, sharpland and o'neill pollinating themselves are not effective and must be equipped with pollination trees in order to produce sufficient results. The family pellets are not easily selected for this type of plant. The bushes are suitable for open planting in the north and other varieties can be used as family pellets。
Soil requirements
Blueberries, acrylic, softer, defusing, organically rich soils, which generally require soil ph values of 4. 5 to 5. 5, soil organic content of 8 to 12 per cent, family pellets can buy the fertilized soil that is common in the flower market and, depending on their condition, add organic matter such as mosaics or herbide, wood crumbs, rotting pine pellets, etc., to be watered at normal times with white vinegar (recommended: 500 ml per month with half spoon vinegar) and fertilization should also be applied with attention to the application of acid fattening, with emphasis on the following: blueberries are calcium plants and do not cut into the soil。
Iv. Containers
It is recommended to use a well-breathed basin, followed by a saline basin, followed by a plastic basin, and not a pottery or ceramic basin. Because blueberries are stubble, shallow root systems, do not need large basins, use deep basins, small seedling basins suggest 15 cm basins, finished plant 25 cm basins and small seedling basins。
V. Climate conditions
A very important factor in ensuring the outcome of pellets blueberries is to ensure that winter blueberries experience a low temperature hibernation of less than 7. 2°c and are subject to a different and different minimum temperature viewing variety, such as as viewing flowers, without a low temperature limit。
Vi. Waterwater management
The blueberry root system is relatively shallowly distributed and is less sensitive to moisture, and should always be wet and unwatered, with differences between the different growing seasons. While the most appropriate water conditions can always be maintained at the stage of nutrition growth, strong plants must be promoted and properly reduced before the fruits grow and the fruit matures, preventing excessive nutritional growth from competing with the fruit for nutrients, restoring the most appropriate water supply after harvest and promoting nutritional growth. In order to maintain soil acidity by reducing the water supply between mid-autumn and late-autumn, it is recommended that the amount of vinegar of 3-5 degrees be applied to 500 ml per month, with half a spoon。
Vii. Fertilization
Blueberries are oligotrophic and have low nitrogen, phosphorus, potassium, calcium and magnesium levels compared to other fruit trees. As a result of this characteristic, blueberry fertilisation is specifically designed to prevent overdose and avoid fertilizer damage. When blueberries are planted, the soil is integrated into organic matter, so blueberry fertilisation is mainly directed towards fat。
The fertilizer suitable for application in pellets of blueberries is phosphorous pentaoxide and ammonium sulphate. Blueberry over-fertilization is highly susceptible to tree damage and even death. Therefore, the application of fertilization must be measured carefully, depending on the fertility of the soil and the nutritional status of the tree body. In addition, blueberries cannot be applied to nitroferant, e. G. Ammonium nitrate, potassium nitrate, etc。
Viii. Blueberry oscillation
The period of trim may be divided into winter trim and summer trim, strictly between hibernation and growth。
The young trees that have just been planted need to cut off the buds and the timid branches. There is also a general need for short cut-off of strong branches to varying degrees. The first growing season of life is designed to be as low as possible or not to be cut in order to maximize the number of canopies and branches。
In the first three years of winter, the larvae have been trimmed, mainly by cutting down the lower branches, laying down the branches, the horizontal branches, the cross branches of the corks, the overtows, the overlapping branches, etc. The bud at the top of the branch can be cut slightly. Following the onset of the spring, some of the new developments should be selectively eliminated as early as possible to enhance the retention of the new developments。
After the ferocious period, the size of the canopy has largely met the requirements and should begin to control the further expansion of the canopy, leaving limited space for the growing branches or branches. The principle is to stay weak. In addition to the weak branches, the ill branches, the dead branches, the cross branches and the adjacent overlapping branches are also subject to removal。
It's a good story
