Tree age selection
Apple trees with 8 years old and below can be transplanted. If dense plantings below 8 years of age need to reduce density thinning, consider transplanting the apple trees to be thinned into new gardens, or replanting them in the missing plants. Especially in the case of heavy construction, planting large trees can effectively prevent the occurrence of replantation.
Transplanting time
It should be carried out 15 to 20 days before the apple tree sprouts. The central and southern parts of Hebei Province should be transplanted in the middle and late March, and the northern areas should be transplanted from late March to early April.
Transplanting method
When the transplanting distance is relatively close, the big tree is best to be transplanted with the soil near the parcel; the long-distance transportation of the big tree can be transplanted without soil, and the soil can be transplanted with the condition.
Transplanting method
1. Carrying a large ball with a soil ball to transplant. Water is poured 1 day before the tree is dug, and the roots are kept intact and the roots are taken as soil. After digging, use a plastic bag, straw rope or sack to wrap the soil ball to the planting site. When transplanting, you should dig 100 cm l00 cm and 80 cm of planting pits in advance (depending on the size of the soil ball and the width of the root system). When planting trees, bury the soil and work hard, especially in the large gaps of the roots. The soil can be compacted with wooden sticks, so that the roots are in full contact with the soil. When the ground is buried, the watering pits are built, and then the water is poured, and the water is fully infiltrated. After straightening the trunk, cover the soil to the same level as the ground.
2. Transplanting without the earth ball. Try to keep the roots intact when digging trees. Lightly transported during transportation, covering the shade, avoiding damage to the tree and roots. When transplanting, we should dig 100 cm, 100 cm, 80 cm of planting pits in advance (depending on the size of the roots of the fruit trees and the width of the roots). It is best to plant the day on the day of the excavation to minimize the time for excavation and planting. The roots were trimmed before planting, the damaged parts of the roots were cut and the roots were mixed into a 50 mg/kg solution, and the roots were sprayed with a sprayer. When planting trees, bury the soil and practise the soil, especially the large gaps in the roots. The wooden sticks can be used to make the roots fully contact with the soil. When the planting pits are 2/3, the water is poured, and the soil is fully infiltrated and then covered with soil. Level with the ground, water the pond again after watering, and cover the soil until it is fully infiltrated.
Post-plant management
1. The tree is fixed. In order to fix the tree body and prevent the root soil from cracking and causing the water to disperse, a pile of 30-50 cm high mound may be piled at the base of the main root, and the tree body should be fixed by the bracket at the same time in the windy area.
2. Tree trimming. For trees with large root damage and no soil transplanting, all lateral branches should be removed; trees with less root damage and transplanted with soil can remove some large branches moderately, and the lateral branches are properly short; the roots are relatively intact and soil Transplanted trees can be not trimmed.
3. Water and fertilizer management. If there is continuous dry weather in spring and summer after transplanting, water should be poured once every 15 to 20 days to ensure sufficient water supply. Large trees that have just been transplanted should not be fertilized, so as to avoid burning roots and rotten roots. After the tree survives, it will be properly topdressed from July to September, and combined with spraying, foliar spray fertilizer will be applied in time.
4. Cover the insurance. In order to reduce the loss of soil water and increase the ground temperature, it should be covered or covered with grass after planting. Before the film is covered, the tree plate should be flattened into a shape with a slightly lower internal height. The film coverage should be larger than the planting pit or the whole line of the film; the grass cover can be covered by a tree tray or covered with whole rows, and the cover can be selected from straw and green grass. , wheat straw, etc., thickness 15 ~ 20 cm, flower point type of soil, to prevent the wind blowing.

Single Use Trocar Site Closure Device
A fascial closure device is a laparoscopic instrument used to close the fascia, the layer of tissue that covers and separates abdominal organs and muscles. The device is used during laparoscopic surgery to create a secure closure of the fascia after the surgical procedure is complete.
The fascial closure device consists of a needle and suture material attached to a handle. A needle is used to puncture the fascia, then suture material is passed through the puncture site and tied tightly to close the fascia. The device's handle is used to control the movement of the needle and suture material, allowing precise placement and closure of the fascia.
The use of fascial closure devices during laparoscopic surgery can help reduce the risk of postoperative complications such as hernias, wound infections, and intestinal obstruction. It also closes the fascia more quickly and efficiently, reducing the overall time required for the procedure.
