What is the price of blueberry seedlings? How to plant it?

Blueberry, also known as blueberry, is deeply loved by consumers because of its beautiful color, unique flavor and rich nutrition. It is a fruit tree variety with high economic value and broad development prospects. So what's the price of blueberry seedlings? How to plant it?

What is the price of blueberry seedlings?

The price of blueberry seedlings is directly related to its specifications. Generally speaking, small blueberry seedlings are about 5-7 yuan per plant (except for special expensive varieties), while large blueberry seedlings can be sold for dozens of yuan each.

Second, how to plant blueberry seedlings?

1. Garden site selection

Blueberry planting should choose the middle and lower parts of the east slope and south slope, the slope is less than 30 °, terraces should be built when the slope is large, and the garden should be built in places with loose soil, fertile soil, good drainage, moist but no stagnant water.

The growth of blueberry needs strong acidic soil conditions, and the key to cultivating blueberry is soil improvement, adjusting the soil pH value to about 5, and the content of soil organic matter is not less than 5%.

There are many propagation methods of blueberry, such as cutting, seedling, ramet and other methods can be used. At present, blueberry cultivated in China is usually based on cutting propagation, and other methods such as seed breeding, rhizome cutting and ramet are also used.

In recent years, through the continuous efforts of growers, tissue culture and other means have been deeply studied, and a relatively simple method of blueberry propagation has been explored for various places, and the method of industrial breeding of tissue culture has been applied to production. The development and application of this technology has provided a large number of non-toxic seedlings for blueberry production, and has gradually become the direction of blueberry high-quality seedling production in the future.

2. Variety selection

In the middle and lower reaches of the Yangtze River, strong soil viscosity plots give priority to varieties with strong adaptability, such as Nanjin, brilliant rabbit eyes, emeralds and so on.

Southern humid and cool microclimate areas: you can choose to plant some southern high clump varieties such as haze, O'Neill, emeralds, jewelry and so on.

In the northern region, blueberries are mainly in the north. Duke, a high early-maturing big fruit variety in the north, or O'Neill, haze, a high early-maturing variety in the south, are recommended in the facility.

Considering labor, management and other factors, the area of continuous garden should not be too large (it is suggested that 100,300 mu), and the varieties should not be too many (2 to 3 varieties), so as to facilitate management.

3. Soil improvement.

In order to thoroughly improve the soil environment of blueberry growth, it is recommended to thoroughly improve the soil and change the whole garden.

In the autumn of the year before planting, the soil of the whole garden should be deeply turned over 40~60cm, the drainage ditch was dug, and the gentle slope was adjusted into a gentle slope. After applying sulfur powder, the specific dosage should be determined according to the measured soil pH condition, and rotary tillage could be applied twice to ensure uniformity.

The amount of material input per mu before rotary ploughing is about 5 square meters of peat, about 3 tons of organic fertilizer, and the bark covering thickness of sawdust or diameter 3~5cm is 5~10cm, 30-50 square meters per mu.

In order to avoid nitrogen deficiency caused by sawdust, it is also necessary to add 15kg/ mu urea or other kinds of nitrogen fertilizer along with sawdust. Ensure that all kinds of materials are evenly mixed with the garden soil, and the improved soil is basically returned to the ridge after ridging.

4. Colonization

Planting time: blueberries can be planted in spring, autumn and winter, and the planting in Northeast China is the best at the end of spring.

Seedling selection: 35~50cm is suitable for seedling height, with more than 2 to 3 upright and strong branches, healthy trunk branches without aging, old and weak branches, not old seedlings. The root system is light yellow, developed, not blackened and without root root phenomenon.

Planting method: the planting hole was dug on the ridge during planting, and the size was about 40 × 40 × 40cm. Add organic fertilizer 5kg and compound fertilizer 30g to 50g at the bottom as base fertilizer, add more soil and mix well, and leave it at the bottom. Cover a layer of soil, then add some peat, insecticide and soil to mix well and leave it on the upper layer of the planting hole, ready to plant.

When planting, soak the seedlings in water in advance, take them out from the bowl, shake off the roots slightly, dig a small hole of about 20cm × 20cm on the planting hole that has been dug, plant the seedlings, gently firm, and pour through water. Cover with pine needles, rice stalks, sawdust and other moisture and acid, covering higher than the ground 15~30cm is appropriate.

5. Fertilization management

Base fertilizer: the most suitable application time is from autumn leaf discoloration to defoliation, and the effect of early application is better than that of late application. Generally, it is mainly rotten sheep dung, cow dung and rabbit dung, which is fertilized by the way of trenching, 10~15kg/ in full fruit stage and 5kg/ in young trees.

Topdressing: in the period of topdressing, in the period of leaf bud germination, before and after flowering, it is mainly quick-acting fertilizer, which is suggested to be combined with the root application of sea elves biological stimulant; a small amount of phosphorus and potassium fertilizer can be applied after fruit harvest to avoid the growth of shoots caused by more nitrogen fertilizer and promote root growth. the branches are strong.

6. Water management

Blueberry young fruit development period of water supply should be adequate and stable, avoid sudden drying and sudden wet, otherwise it is easy to cause red fruit, fruit. When the drought time is predicted to be more than 7 days, ensure that the water is fully watered within 5 days, and the watering should avoid the noon period with high external temperature as far as possible.

Blueberries are more sensitive to waterlogging and must be drained in time, and it is not good for blueberries to be waterlogged for half a day. The planning of drainage and irrigation facilities should be combined with the extreme flood weather in the local history, which is particularly important in blueberry cultivation in the southern flatlands.

7. Disease and pest control

Blueberry diseases and insect pests are few, common powdery mildew, downy mildew and so on; pests are aphids, mites, fruit flies, longicorn beetles, beetles and so on.

We should pay attention to prevention and comprehensive control, protect and utilize all kinds of natural enemies, maintain the ecological balance in the blueberry orchard, give priority to physical and biological control, and use chemical control if necessary, but use low-toxic, safe or biological pesticides. And pay attention to the safe drug isolation period.
