Dwarfing cultivation techniques of Myrica rubra

Dwarfing and dense planting is the general trend of fruit tree cultivation in the world, which can make fruit trees bear fruit early, early and high yield, and it is an important cultivation mode to obtain high benefit. By using dwarfing cultivation technology, controlling tree crown by cutting stem, pruning, rational fertilization and chemical regulation, the vegetative growth can be transformed into reproductive growth, which can promote the early fruiting of red bayberry, which is generally put into production 3 to 4 years earlier than the conventional cultivation methods. and effectively reduce the annual fruit phenomenon, improve yield, improve quality, improve economic benefits. The main technical measures for dwarfing red bayberry are as follows: 1. It should be planted properly. According to the different growth trend of different varieties, the cultivation density is as follows: Dongkui 5 × 6 meters, Ding Kui and Zaocai 4 × 5 meters. two。 Without a main pole. After planting, the spring shoot took off the core, leaving no main stem, leaving 2 or 3 side branches to form the first branch, and then selecting 2 to 3 buds from the first branch to form the second branch in the second year, so that after 3 years of cultivation, the dwarf tree foundation was formed. 3. Pruning and core-picking control height. Pruning and core-picking twice a year, through pruning and core-picking, to remove the strong and retain the weak, to promote balance, to close and expand the crown, to make the crown ventilated and transparent, to achieve the purpose of suppressing the tree type and expanding the crown range. 4. Rational fertilization to promote balance. Control nitrogen and increase potassium, look at trees to fertilize, according to the law of fertilizer demand of bayberry, each shoot consumes a lot of nutrients. Apply fertilizer three times a year, that is, spring fertilizer, summer fertilizer and autumn fertilizer, and use special compound fertilizer for fruit trees in spring and summer, and apply it before new shoots germinate. Autumn fertilizer was applied to soil and miscellaneous fertilizer from late September to early October. 5. Chemical regulation to promote flowers and fruits. When young fruit trees enter the fruiting stage, the crown is sprayed with paclobutrazol to control the length of the new shoot, keep the new shoot at about 20 cm, and become the best fruiting branch group to promote the formation of flower buds.
