Pots and roots for potted fruit trees

Potted fruit trees are easy to breed, low in cost, beautiful in shape, fruit and fruit, and long in sight. They are often used in environmental greening and interior decoration and are loved by many families. Potted fruit trees Due to the limited volume of the container, after a period of growth, the root system will be limited, affecting the growth and development of the aboveground parts, thereby greatly reducing the ornamental value. Therefore, when potting fruit trees, care must be taken to change pots and roots. First, there are several situations in which pots need to be changed. 1. Perennial plants grow in pots. As the age increases, the roots overlap in the pot and crowd each other, affecting the development of new roots, and the ability to absorb nutrients is significantly weakened. In order to change the above situation, it is necessary to change the basin treatment, and at the same time strengthen the management of fertilization, and properly trim the root system, so that the plant will be fully renewed and play a role in rejuvenation. 2. The plants grow up. The original pots are not adapted to the requirements of plant growth. The volume must be expanded to meet the absorption of nutrients by the root system. At this point, you should replace the larger pot. 3, the original basin soil long-term absorption and utilization of plants, lack of mineral nutrients, easily produce symptoms of deficiency. When the physical properties of the pots deteriorate, the aeration becomes poor, which can lead to poor plant growth. For both cases, replace the old soil in the pot with a new one. 4. When there are pests and diseases in the root system, the root system should be repaired, combined with disease prevention and pest control, and the replacement basin should be treated. Second, change basin time can be carried out in spring and autumn. In spring, the deciduous fruit trees are carried out before the roots begin to grow for the first time, and the evergreen fruit trees are generally carried out during the rainy season. In the fall, it should be performed after the autumn shoots of the fruit trees have stopped growing and before the peak of the root growth appears again. Third, the method of changing pots to the principle of not hurting the roots or hurting the roots, the specific operation method may depend on the size of the basin. When basins with a diameter less than 40 cm change the soil, first hold the base of the plant with your left hand and lightly push the pelvic wall with your right hand. Then slowly lower the basin and push your thumb to push up the bottom tile of the hole at the bottom of the basin. Separation from the pelvic wall, and then lift the pot, the two feet grip the pot, his hands and pull up the potted soil. Fourth, after the growth of potted roots, the roots are old and densely crowded. In order to maintain the vigorous growth of fruit trees, the roots should be changed every 1-2 years in order to be constantly updated. The specific method of cultivating the roots: The first step is to clean the soil ball, that is, use bamboo to gently remove the surrounding old potted soil and remove 1/2–2/3 of the total basin soil volume. The second step is to cut the root. If you find that the root has curled along the wall, you can shorten it. If the root part of the cut is as small as possible. Finally, put a new cultivation soil and plant it in the original basin or in a larger new pot. Large-scale planting boxes are generally not changed basins, and can be used in combination with deep-rooted basal fertilizers in late autumn for root rejuvenation. (Chengdu Lixin Garden)
