Dwarf planting techniques
1. Choose a variety. Use red oil, red buds, and red scent. Its characteristics: early germination, high temperature resistance, resistance to barren, good commercial quality, easy to control the tree, suitable for dwarf close planting. When the shoots were first born, the buds and young leaves were red-brown and bright. After elongation, the top 1/3 of the stems remained red, and the rest gradually turned green. The buds and the compound leaves are stout, crisp and juicy, with less slag, sweet, thick aroma, and no bitter astringency. 2. Improve the quality of the park. Select sandy soil with deep, loose, moist and well-drained soil. The planting density is generally 2300 per mu and the row spacing is about 0.5m0.6m. After survival, the main seedlings were cut at 15-20 cm to promote primary lateral branches. When the first lateral branch grows to 30cm, it is topped and promotes secondary lateral branch. 3. Soil and fertilizer technology. Deep plowing and expanding the hole, planting summer green manure between rows, prevent grassland and protect the root system. In the autumn, 3000-4000 kg/mu of organic fertilizer is applied. After the shoots are picked up to August, the fertilizer can be applied 4-5 times, and 70 kg/mu. 4. Rational pruning, sparse planting, pest control, timely harvest.
