How to make young bayberry trees bear fruit early?

How to make young waxberries bear fruit early? Please guide the introduction to make the young trees of bayberry early fruit can refer to the following planting techniques: First, planting selection ferns, azaleas and other broad-leaved trees dominated sandy mountain planting easy early fruit high yield. Open terraced fields, dig planting holes of 1.2× 0.8m, apply decomposed railing fertilizer 50kg and calcium superphosphate 1~ 2kg in the holes, select strong seedlings with 3~4 branches and thickness above 0.7cm, plant deeply, cultivate soil to branch points, and only water but not fertilize after planting. In the same year of planting, shade with branches to improve survival rate. 2. Fertilization 0.1 kg urea and 0.05 kg potassium fertilizer were applied to plants in August of the planting year, and compound fertilizer was applied in October and November.(N∶P∶K∶7∶8∶15) 0.25kg and plant ash 0.5~ 1kg, compound fertilizer 0.5~ 1kg per plant in May ~ June of the second to third year, and 25kg fence fertilizer combined with deep ploughing and hole expansion in October as base fertilizer; after fruiting from the fourth to fifth year, calcium superphosphate 0.25kg, potassium fertilizer 1~ 1.5kg per plant in May ~ June, and fence fertilizer 25kg and plant ash 2.5kg in October ~ November. If the tree is too prosperous, it is easy to cause flower and fruit drop, then the basal fertilizer or topdressing are not applied nitrogen, only potassium fertilizer. Third, shaping and pruning early fruit bayberry should be changed into a trunk shape with open heart shape and three main branches. Natural open-heart shaping, leaving 3 main branches at intervals of 10~20 cm on the trunk, branch angles of 45°~50°, and then leaving 1~2 large branches pulled down as auxiliary branches, cutting off the rest of the large branches, leaving the first auxiliary main branch at 70 cm from the trunk in the next year, the second auxiliary main branch 60 cm away from the first auxiliary main branch, and leaving 30 cm short on the auxiliary main branch. The modified trunk shape dominated by three main branches is modified on the basis of the modified trunk shape, i.e. strengthening the three main branches at the base, compressing the trunk and its main branches and lateral branches, strengthening the trunk, replacing the trunk with weak branches, and girdling to slow down the tree vigor and promote fruit. Large-scale auxiliary branches can be pruned by pulling branches, ring cutting, digging and evacuation (i.e., removing top strong branches and leaving weak branches) to promote fruit. Opening the angle of main branch and auxiliary main branch can promote fruiting. When pruning, under the condition of not affecting ventilation and light transmission, the lower part and internal weak branches shall be kept as far as possible, and it is forbidden to "cut off but not cut on, cut inside but not outside". 4. Promoting flower and fruit preservation If young trees are prosperous (crown diameter is more than 2 meters) and do not bear fruit, in October, according to different varieties of trees, the effective component of paclobutrazol per square meter of crown projection area can be applied to the soil 0.15~0.4 g, or 750~1000 mg/L paclobutrazol can be sprayed in late June to control shoots and promote flowers. Spraying gibberellin 10~15 mg/l once at full bloom to keep fruit, and spraying nutrient solution in the middle and late May to promote large fruit (fruit shape is small at the beginning of fruit). Five, pest control and control of brown spot disease in mid-May, late and after fruit picking spray a tophujin or carbendazim, scarab, roller moth, etc. can choose 80% dichlorvos 1000 times liquid or 20% methomyl 2000 times liquid control.
