How to increase the survival rate of fruit trees
Fruit trees and cultivation 1. Seedlings are planted: When the seedlings arrive, they should be advanced if they are not planted. Prosthetic method: Select the back of the room to dig trenches, generally 40 cm deep and 80 cm wide, depending on the number of seedlings. If the soil is dry, irrigate the water first and then dig the ditch after the water passes through. Cut the seedlings to about 10 cm above the fixed height, untie the tied ropes of the roots of the seedlings, and place the seedlings at an angle of 45 degrees from the bottom of the ditch. Arrange the roots evenly on the inclined surface of the ditch, and then cover the bare end of the ditch. If there is a water loss in the roots of the seedlings, they can be soaked in water for 12-15 hours and then replanted. Second, seedling spacing: Plant spacing due to the topography, soil type, tree species, rootstock and so on are different, soil infertile mountain, wasteland or use of dwarf rootstock seedlings can be planted slightly, plain, fertile soil can be sparse. Plant spacing is 2 meters or 3 meters, spacing can be 4 meters or 5 meters; apples, plums should be configured when the pollination tree, apple 6:1, plum 4:1. Nectarines and peaches are self pollinated. Third, acupuncture, ditch preparation: early tree planting points deep 60-70 cm, diameter 60-70 cm, the size of planting holes should also be determined according to the quality of soil, good soil digging a small hole, poor soil to dig large holes, The topsoil and the soil and soil are to be placed separately. The topsoil and the decomposed earthworms are mixed and filled into the lower part of the tree. The heart and soil are placed on the surface. The root zone and the fertilization zone are separated by 20 cm. It is forbidden to apply fresh manure as a base fertilizer to prevent root damage. Nectarines and plums can also be planted without applying base fertilizer. Fourth, planting wood planting: spring seedling fruit seedlings to see the situation first, if there is water loss in seedlings should be immersed in the room with water for 1 day and night, so that the seedlings fully absorb water before planting. Planting time is generally 5-10 days before the initial flowering period of local apricot trees. The depth of colonization is usually based on the root and neck traces of the seedlings. The interface should be on the windward side, the roots should be stretched, then soil, practical, irrigation, water infiltration and then sealed, in order to facilitate the preservation of water. Fifth, seedlings will be dry: After the fruit trees are planted, they must be dried in time. Most of the apples have a central leadership tree shape and require 70-80 cm to be dry. Peach, nectarine, plum, apricot, and cherries generally adopt a happy shape and should be dried at 50-60 cm. Cut the mouth under the 20 cm plastic belt to stay full of buds selected for the main branch.
