Black pine transplant attention

What should be paid attention to when mining black pine? When mining, it is necessary to expand the mining surface, paying attention to bringing as much soil as possible. Because black pine grows in the hillside sandstone soil, the soil is less, and the weather is dry in winter, the soil moisture is less viscous, so it is necessary to protect the root soil as much as possible during mining. Because the root soil is rich in mold on the roots, it is a symbiotic of black pine, which is very beneficial to the growth of roots. After the excavation, the plastic bag should be used for simple dressing in time to prevent the soil from being lost during transportation for transplanting. Second, pay attention to the root part of the black pine when mining. Start mining in a place farther away from the pine tree. First, the surrounding soil should be hollowed out. The main root should be kept as much as possible. The root cut should be smooth and the roots should be cut off. Try to avoid hurting the root system. In particular, the lateral roots and fibrous roots of the black pine in the sandstone are weak, and the length is as long as possible, especially when mining. Third, the black pines that have been harvested must be in time for the soil. The faster the time, the better. If the time is long, the roots will lose water and dry up, which will affect the survival. In order to prevent the root from being buried too deep, high planting and shallow planting can be adopted, and then the soil is covered with the soil. If it is not cultivated in the ground, it should be put on the basin in time. Fourth, the upper basin of black pine is very important. Before planting, the bottom of the pelvic floor will be crushed with gravel and tiles to facilitate ventilation and drainage, and then the soil will be filled around. The gap in the soil is too large, which is easy to cause freezing roots, and the straw is covered with straw to prevent freezing. Fifth, the soil is best used on the mountain, and mixed soil made of coarse yellow sand, coal ash and yellow mud can be used. The ratio is O. 5:0.25:O. 25. Sixth, it is necessary to repair it in time after the upper basin. Too much branches and leaves will affect the root water supply and consume a lot of water and nutrients.
