The reasons for fruit tree growth are mainly the following: First, the reasons for varieties or seedlings themselves, such as peaches, plums, pears, chestnuts and other varieties are very prone to leggy; grafted seedlings rootstock, scion, seedling raising techniques if there are problems will appear to be long. In general, seedlings grown from seeds are easy to grow. The second is the reason for trimming plastic surgery. When the saplings are reshaped, the large branches are left too little or clustered, the nutrients are too concentrated to supply, the collaterals are too few or cut too much, the affiliation of the main lateral branches is not obvious, and in the pruning, the summer does not pay attention to the timely control of the top, and it reaches winter. When pruning, short cuts on strong branches, and cut too much on small branches, can also cause leggy. The third is improper fertilization. During the young and young years, partial application of nitrogen fertilizers, fertilizers or large fertilizers, and the application of organic fertilizer is very small, do not pay attention to the combination of phosphorus and potassium fertilizer, long-term excessive soil moisture, but also cause leggy. To prevent the fruit trees from growing in length, grafted seedlings must first be planted and seedlings not planted. Seedlings are easy to grow, and the flowering results are late. The root stocks of grafted seedlings should be selected from the native soil-dwarf type. Rootstocks with developed main roots and few lateral roots should be cut with a portion of the main roots, or the long main roots must be turned in a circle. This can promote lateral root growth and dwarfing. Seedlings; from the already grown adult mother trees, select middle branches that are sunny, robust and free of pests and diseases. Do not take branches from young plants that do not produce fruit. When planting, the main root of the seedlings is appropriately shortened to promote the growth of lateral roots, and the plants are not easy to grow. In pruning and shaping, summer topping should be the main method, supplemented by winter shears, and it can also be controlled by measures such as pulling, bending, and twisting on the branches, and in winter pruning, the long branches should be lightly cut and moderately short. Cut some of the main branches of the extension of the branch; in the plastic surgery, the strong branches of the branches should be properly retained, the side branches should also be left as the result of the branches, fruit control shooters long, the lower branches can advance results, as long as the mop should be retained, As a result, early results can be achieved, and second, the plants can be controlled. For Wangshu, by cutting off the long main branch, ring cutting branches and other measures, you can also control the leggy; new shooters long, through the spray than a long time, paclobutrazol, chlormequat and other growth regulators, inhibit shoots leggy. In fertilization, we must pay attention to applying organic fertilizer. When the sapling reaches the late stage of growth, it is necessary to control the application of nitrogenous fertilizer and water and fertilizer, and to increase phosphorus and potash fertilizer. After the new shoot grows to a certain length, it is necessary to pay attention to controlling the fertilizer and water. Too much water in the orchard should be well drained. If necessary, roots, roots, and even roots can be removed.

Planting fruit trees often encounters leggy phenomenon, causing a large amount of nutrients to be consumed, and the result can not be flowered as a result of the age of the tree, or the flower production can be reduced.
