Pear tree planting process, pear tree planting an acre of how many reasonable?

At this stage in the production and processing of pear trees key to the following three planting methods:

Plant spacing in accordance with the 2x4 meters long, mu planted pear tree 83 plants up and down, choose the fusiform branching; plant spacing in accordance with the 4x4 meters long, mu planted pear tree 42 plants up and down, choose of course the happy shape of the branching; plant spacing in accordance with the 1.5x3.5 meters long, mu planted pear tree 127 plants up and down, choose a side to side of the shape of the tree branching;

Cultivation techniques: A, according to the plant spacing designated digging holes, general sandy soil, hole width 80cm, 50-60cm deep; rice grotto width 80cm, 40-50cm deep can be. First put into to 30-40cm swing wheat grass, branches or green manure crop branches, poles, etc., and the subsoil will be added to step tightly, and then apply organic fertilizer (pig, sheep manure) 50-80KG or huller pig manure (20KG) or pure pig manure (10KG) need to compost fertilizer,

and add calcium magnesium phosphate fertilizer 1-2KG (alkaline soil layer can be used phosphorus fertilizer) and soil mixing to fill in, made of steamed bun shape. b. Before planting Need to pear seedling thick root cut planting 2-3cm, promote new root production, grafting method at the plastic film needs to be eliminated, in order to prevent harm to the growth and development of the main pole. c. planting grafting method need to expose the road surface 5-10cm, stabilized sense of the soil layer, watering immediately. Out of the wind outlet area, need to open support, to prevent the fall of seedlings.

Soil improvement on the fertilizer

Soil layer deep turning ripening is pear tree high-yield technical in the basic method, in order to think of peach tree high-yield, bumper crop, high quality, essential from the improvement of the soil layer to start. Deep turning soil improvement is generally in the fall after fruit picking, to carry out in the winter before the dead leaves, and its methods are expanding the hole, garden level deep turning, spaced rows or inter-plant deep turning. Deep turning depth is generally 30-40cm is appropriate, there are standard locations can be taken every other tree turn over, 1, 3, 5 years in the original hole on both sides of the opening of a depth of 2.5 feet wide 1.5 feet of concave ditch, 2, 4, 6 years in the other two sides of the opening of concave ditch, the fusion of the application of fertilizer into the bottom.

Spread into the bottom fertilizer specification, generally 100Kg of product at least 100Kg of organic fertilizer (pig, sheep farmyard manure), and then seeped into the 2.25Kg of phosphorus and potash fertilizer, is beneficial to the production of quantity and quality enhancement.

In addition to the bottom fertilizer, in the growth period should also be moderate fertilization, generally provides for three fertilization, the first flower shedding fertilizer, time in mid-April, to promote the growth and development of branches, flower bud division and fruit Pangda; the second fruit expansion fertilizer, time in mid-to-late May - early to mid-June; the third post-harvest fertilizer, time in mid-to-late August - mid-to-late September, to enhance the color of the tea leaves, to increase the service life of the leaves, to repair the plant shape.

Extra-root fertilization can be fused with dosing into the appropriate nitrogen, phosphorus, potassium and other fertilizers, the common concentration value of urea solution 0.3-0.5% (0.2-0.3% at high temperature), phosphorus fertilizers 0.5%, ammonium sulphate 0.3-1%, potassium phosphate 0.2-0.3%, in addition to composted human urine 5-10%, grass ash soil solution 3-10% (not to be mixed with chemical fertilizers).

Configuration of pollinating trees and three sparse technical

Pear is a heteroflowering pollinating green plants, most kinds of self-flowering is not firm, so essential in the flowering period basically meet the pollinating species, the main plant and pollinating species equipped with the ratio of the best 2:1 or 1:1, at least 3:1 or 4:1, in order to achieve a good harvest and high yield. Japanese pears (Kouzui, Fengshui, Chikusui) and Crown, Aroma, Crisp Green can pollinate each other.
