If the apple tree is transplanted, what is the better age? When is the survival rate high? What are the transplanting methods?

Transplanting, also known as transplanting, refers to the operation of transplanting seedlings in the seedbed to the field. Transplanting can take soil or no soil, with soil transplanting root injury less, can shorten the slow seedling period, early life and early start. When the apple tree is transplanted, what is the better age? When is the survival rate high? What are the transplanting methods?

When the apple tree is transplanted, what is the better age?

Big apple trees with less than 8 years old can be transplanted. If densely planted orchards under 8 years old need to reduce thinning, consider transplanting the thinned apple trees to another new orchard, or replanting for lack of trees. Especially in the case of continuous cropping garden, planting big trees can effectively prevent the occurrence of replanting disease.

When is the survival rate high when apple trees are transplanted?

1. Transplant apples in early spring (late March to early April) or late autumn (October to November) in most climates. Avoid transplanting in extreme weather conditions in autumn. Areas with mild climates are at risk of melting frost or heavy or waterlogged soil due to snow cover.

2. Transplanting should be carried out 15-20 days before apple tree sprouting. The central and southern regions of Hebei Province should be transplanted in mid-late March, while the northern regions should be transplanted from late March to early April.

What are the transplanting methods of apple trees?

1. Big trees with soil balls are transplanted. Pour enough water one day before digging the tree, and try to keep the root system intact and carry soil when digging the tree. After digging, wrap the soil balls with plastic bags, straw rope or gunny bags and transport them to the planting site. When transplanting, the planting pit of 100cm × 100cm × 80cm should be dug in advance (the size of the soil ball and the root system should be adjusted flexibly). When planting a tree, while burying the soil, especially the large gap of the root system, you can tamp the soil with a wooden stick to make the root system in full contact with the soil, bury it to the ground and build a watering pit, then pour enough water, and so on, straighten the trunk and cover the soil until it is level with the ground.

2. Big trees are transplanted without soil balls. Try to keep the root system intact when digging trees. When transporting, load lightly and cover shade to avoid damage to trees and roots. When transplanting, the planting pit of 100 cm × 100 cm × 80 cm should be dug in advance (the size of the root system of the fruit tree should be adjusted flexibly according to the root size and root amplitude). It is best to dig and plant on the same day and shorten the time of digging and planting as much as possible. Prune the root system before planting, cut off the damaged part of the root tip with oblique stubble, and prepare the strong rooting powder into a solution of 50 mg / kg, and spray all the roots with a sprayer. While burying the soil while planting the tree, especially the large gap of the root system, you can tamp the root system with a wooden stick to make the root system fully contact with the soil, bury it to 2 / 3 of the planting pit and pour enough water, wait for the water to seep fully, cover the soil until it is level with the ground, water again after building the watering pit, and cover the soil until it is level with the ground after the water is fully seeped.

Post-planting management

1. The tree is fixed. In order to fix the tree and prevent the loss of water caused by cracks in the root soil, a 30-50 cm high mound can be piled at the base of the main root, and a bracket should be used to fix the tree in the windy area.

2. Pruning the tree. The trees with large root damage and transplanting without soil should remove all the lateral branches; the trees with less root damage and transplanting with soil can appropriately remove some of the large branches and truncate the lateral branches properly; the trees with complete roots and transplanting with soil can not be pruned.

3. Water and fertilizer management. If there is a persistent drought in spring and summer after transplanting, water should be irrigated every 15 to 20 days to ensure adequate water supply. Trees that have just been transplanted should not be fertilized so as not to cause root burning and rotting. After the tree survived, the tree should be fertilized properly from July to September, and foliar fertilizer should be sprayed in time combined with spraying.

4. Mulching to preserve soil moisture. In order to reduce soil moisture loss and increase soil temperature, plastic film or grass mulching should be applied in time after planting. Before film mulching, the tree plate should be leveled into a shape that is higher on the outside and slightly lower on the inside, and the scope of film mulching should be larger than that of planting pits or the whole row of film mulching; grass mulching can be covered by tree plates or the whole line, and the mulch can be covered with straw, green grass, wheat straw, etc., with a thickness of 15cm and 20cm.
