2. Insert sand first, and then transplant to continue rooting after rooting. The second is to cut roots directly underground. Because most Lycium barbarum cuttings with roots instead of stems take root in the cross section, but there are not many roots, and often two or three main roots keep growing. In order to make it take more roots and improve its ornamental value, the author adopted the method of secondary cutting.
3. After the first cutting survives, let it grow vigorously underground for one year, then dig out and cut off the new roots before the second germination, leaving only 1 ~ 1.5cm, repair the section with a sharp knife, and cut off the part of the original section that has healed but does not grow new roots, and then carry out the second cutting, and put a little plant ash at its root. In this way, the surviving old pile of Lycium barbarum will produce more roots on the severely injured surface and new root segments at the same time than the first cutting. After two years of cultivation in the field, it can dig out the upper pot and make a perfect wolfberry bonsai.
4. In order to make the new roots curl and get better results, the author also used the guiding method to cultivate root claws, which also achieved good results. The method is: first dig a hole of 20cm*20cm*30cm and fill it with river pebbles or brick slag. Pebble and sand mixed layer 15 to 20cm, and then fill with 2cm thick sand. Then, the mended Lycium barbarum is stacked in the into the pit hole, sealed with sand or loess, and then filled with water. After the water seeps down, seal some soil to prevent the old pile from losing too much water and dying. When the new roots of the cut Lycium barbarum pile meet hard objects such as river pebbles, they will turn and extend along the sand cracks, and the sand cracks between the hard objects will guide them to grow into curved root claws. After two years of digging, the ideal flat-rooted Lycium barbarum pile material can be obtained.
