How to plant a pear tree in science
A: First, dig a hole at a fixed distance from the line, usually sandy soil, with a width of 80 cm and a depth of 50-60 cm. First put in straws and sticks about 30 to 40 centimeters, and add the topsoil to it. Then apply organic fertilizer (pig, cow dung) 50 to 80 kilograms or decomposed chicken manure 10 kilograms, and add calcium magnesium phosphate fertilizer 1 ~ 2 kg (alkaline soil available superphosphate) mixed with soil, made of bread-shaped. Secondly, cut the rough roots of the pear seedlings 2 to 3 cm before planting to promote new roots. The grafted membranes must be removed to avoid affecting the growth of the trunk. When grafting again, the grafting interface reveals 5 to 10 centimeters on the ground, which is a solid rhizosphere soil and immediately poured enough water. In the outlet area, pillars need to be established to prevent lodging.
