Planting techniques for pear trees

<

Cultivation steps
1. Dig a planting or planting ditch.
A pear orchard with a distance of more than 3 meters can be planted and burrowed. Centering on the planting hole, a circular or square planting pit with a depth of 1 meter and a width of 1 meter will be dug and the topsoil and heart and soil will be placed on both sides of the hole.
2 plants in the pear garden with a distance of 2 meters or less should be dug and planted, with a depth of 1 meter and a width of 1 meter. The top soil and the heart and soil should be placed on both sides of the trench.
2. Planting ditch. Fertilizer fill 2500-4000 kg of farmyard fertilizer per acre, first fill the topsoil into the lower layer, and then fill in the mixture of soil and manure.
3. Planting. Put the seedlings on the ditch and hole settlement points of the filled fertilizer and soil. The roots stretch and evenly distribute. Fill the surrounding topsoil, fill the soil and raise the seedlings to ensure the roots of the soil and the seedlings are fully connected. Repair the tree plate, irrigate the water, and cover the tree cover to ensure the soil. In general, irrigation of 2 to 3 times of water can increase the survival rate.
Planting requires temperature conditions. In the annual average temperature of 8.5 °C ~ 14 °C area can be cultivated; in less than -20 °C conditions may occur frost damage. In the annual growth cycle, when the average temperature on the day is 7°C, the pears germinate; when the average temperature on the day is higher than 10°C, the pear blossoms; when the average temperature on the day is 24°C, pollen tubes grow faster.
Lighting conditions. Pear is a light tree species, and the annual sunshine hours need 1600 to 1700 hours. Within a certain range, photosynthesis increased with the increase of sunshine hours and light intensity. Therefore, when planting pears, determining the planting density, selecting a good tree shape, controlling the height of the tree and the crown width, and maintaining a certain leaf density on a unit area are all requirements for maintaining good ventilation and light transmission of the pear tree. In addition, the light is sufficient, the outer leaves of the upper part of the canopy are bright, the color is deep and thick, the branches are full, the stout is strong, the fruits are fully developed, the sugar content is high, and the quality is excellent. The illumination is not sufficient, the leaves are pale, thin, the buds are small, the fruit setting rate is low, the growth is weak, and flower buds cannot even be formed.
Moisture conditions. The average water content of each organ of pear is more than 60%, and 90% of the fruit is water, so water is essential for normal growth and fruit development.
Soil conditions. The adaptability of pears to soil is strong, sand, loam and clay can all grow. The pears on the sandy loam soil are fine, sweet, and beautiful in appearance, while the pears on the clay ground are coarse, sour, and coarse. Borax, zinc deficiency and iron deficiency can also occur in the rough sand or saline-alkali soil. Pear most suitable for neutral soil (pH5.6-7.2), 5.5<pH<8.5, can grow results. Secondly, soil fertility is also an important factor directly affecting growth and yield. High soil fertility, especially sudden high organic matter, will allow pear trees to grow strong, stabilize production, improve quality, and continue to increase production. If the soil fertility is low, the growth is weak and the yield is low and unstable.
