Seedling planting After the seedlings are shipped, if they are not planted in time, they can be planted first. The ditch is selected after the back of the house. The general ditch is 40 cm deep and 80 cm wide. The length depends on the number of seedlings. If the soil is dry, first fill the water, and then dip the trench after the water is passed through. Cut the seedlings to a height of 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 to the bottom of the ditch. The roots are evenly arranged on the slope of the groove, and then the roots are covered with soil. Seedling row spacing The spacing of seedlings planted varies depending on the topography, soil type, tree species, rootstocks, etc. The soils with thin soils, barren beaches or seedlings using dwarf rootstocks can be slightly densely planted, and plain and fertile soils can be thinly planted. Plant spacing is 2 meters or 3 meters, row spacing is 4 meters or 5 meters; pear, persimmon, plum and other seedlings should be planted with pollination trees, about 10:1, nectarines, peaches are generally self-pollinated. Hole preparation The depth of the planting hole is 60-70 cm, and the diameter is 60-70 cm. The size of the planting hole should also be determined according to the quality of the soil. The soil is good to dig small holes. If the soil quality is not good, the big hole should be dug. The topsoil and the heart soil should be placed separately. Mix with the fertilized soil and fill the lower layer of the tree hole, and place the new soil on the surface. The root zone and the fertilization zone are separated by 20 cm. It is strictly forbidden to apply fresh manure as a base fertilizer to avoid root damage. Seedling planting Planting time deciduous fruit trees are generally suitable for winter, and evergreen fruit trees are suitable for spring. When planting, it is necessary to normalize and reach horizontal and vertical rows. When planting, the grafting interface should be exposed on the ground, the root system should be stretched, then the soil should be soiled, stepped, and watered. After the water seepage, the hole should be sealed to protect the water. Seedlings Fruit trees should be dried in time after planting, and the windy area should be dwarfed. Peach, nectarine and plum are generally used in a happy shape. They should be fixed in 20~40 cm, and should be filled in 10 cm under the cut. The buds are reserved for the main branch, and the grapes are left with 1 to 2 buds. Disclaimer: Some articles on this website are transferred from the Internet.
