How much is the price of birch saplings? How to plant it?

White birch is a very beautiful tree, not only the trunk is straight and long, the bark is white and pure, it is very eye-catching. White birch grows mainly in the north because it is not resistant to high temperature. White birch also has high economic value and is the only choice as a street tree. Let's take a look at the price of birch saplings. How much is it? How to plant it?

Second, how to plant birch seedlings?

(1) planting requirements and matters needing attention

1, planting planning: should not be planted to the direct sunlight side, should not be a street tree; can be a landscape, courtyard tree, but must be a more shady area;

2. Planting methods in spring and autumn: trees with a small size of 3cm are selected as planting objects, and the transplanting area is the best in the plain in northern Xinjiang, and the survival rate is very low in areas with slightly higher elevations. When transplanting, the soil ball is guaranteed to be 10 times the DBH of the tree, adapt to slightly acidic soil, and should not be buried too deep when planting, which should be consistent with the original planting depth, and apply a small amount of organic fertilizer (sheep dung: must be fermented mature fertilizer) at the bottom of the pit when transplanting. Because sheep dung is acidic, it belongs to acid fertilizer can play a role in soil improvement; in addition, it is necessary to ensure the timely supply of water.

3. Soil quality: if the soil quality does not match, soil improvement is carried out. In order to save costs and achieve results, planting holes are generally used for soil improvement: the PH value of planting soil reaches 5.0Me 7.0, which is mixed with organic fertilizer and slag to increase soil nutrition and air permeability, and birch trees should not be blistered and need to be drained; a layer of stone chips and river sand materials about 15-20cm can be laid at the bottom of the planting hole to play the role of water seepage and drainage. The sawdust, slag and bacteria dregs can be poured to the bottom when watering, so that the root can fully absorb water and improve the survival rate.

4. Standing column support: after planting into the hole, straighten the tree and lift it up slightly to stretch the root system, which is conducive to better and faster rooting and soil consolidation; fill the soil and step on the soil. Build triangle bracket: each triangle bracket to form 120 degrees, one end of the bracket should be buried in the soil Rio 20cm (buried depth according to the actual situation), to be buried firmly, the other end should be fixed in the first branch, the three ends should be tied firmly without hurting the bark, and a layer of strip cloth and other items can be wrapped in the bundling place to protect the bark from damage.

(2) key points for conservation of birch trees

1. Watering: Betula platyphylla is a water-loving tree species, which should be watered frequently, but the amount of water should be strictly controlled: it should be watered thoroughly at one time, not too much, and pay attention to drainage. The first few watering can be combined with ferrous sulfate diluent irrigation. after three consecutive permeable irrigation, the application of ferrous sulfate diluent can be gradually reduced and the watering frequency can be reduced. Then you can enter the normal management and protection.

2. Pruning: White birch should not be pruned in spring to prevent injury. Pruning and pruning of withered and bad branches can be done in autumn. After pruning, the cut should be treated: the cut should be smeared with wound coating to prevent evaporation of nutrients and water and wound infection.

3. Fertilization (ripe organic fertilizer): after planting in spring and autumn, apply a small amount of organic fertilizer in the Weir and mix well with the soil. Within one year after planting, you can apply fertilizer at the 50cm around the root and stem in different seasons, digging a circular or scattered nutrition ditch for fertilization, which is conducive to the full absorption of nutrients. Except for winter, the monthly application of potassium fertilizer can significantly improve the resistance of transplanting seedlings, and is conducive to the growth of branches, making the bark more smooth and white.

4. Sunscreen: although birch likes the light, it is necessary to take measures to protect birch from the sun in the hot summer: cover a sunshade net or set up a micro-sprinkler on the branches to cool and moisturize. Birch trees that have never spent summer in the area after transplanting also need to spray some anti-transpiration agents in the hot summer to meet their growth environment.

5. Pest control: Betula platyphylla has no special diseases and insect pests, so we can do general branch and foliar pest control according to the season.
