How to plant Huanghua pear?

1. Planting season: afforestation in spring is generally chosen. But the difference of temperature in different places is different: in the rainy areas in spring, such as Fujian, Guangdong and Guangxi, it is suitable for afforestation from March to June, or from July to August with bagged seedlings if there is a water source for irrigation, and the planting season in Hainan Province is relatively late. August-September is the best afforestation season. If bare root afforestation is used, the root system must be protected in the process of transportation, and the survival is more guaranteed.

2. Site conditions: the opposite conditions of Dalbergia odorifera are not strict. It is suitable for growth in steep slopes, ridges, bare rocks, arid and barren areas. This tree species is a positive tree species. In plain or hilly areas at low elevations, barren mountains and wastelands below 600m above sea level and sunny slopes and semi-sunny slopes of harvesting land, the perennial temperature is higher, the dry and wet season is obvious, and the soil is brown latosol and lateritic red soil. can be afforestation.

3. Land selection and planting: select flat land, sunny or semi-sunny sloping land, cutting land below the hillside for afforestation and planting in front of the house, clean up the miscellaneous according to the routine before planting, refine the mountain, open a horizontal zone with a slope of more than 20 degrees, dig pits with a depth of 40-50cm each, plant after backfilling topsoil and fertile soil, and step on solid leaching to fix the root water after planting. The row spacing is 3 × 3 or × 3 × 2m.

4. Tending of young trees: in the same year after planting, the soil was loosened and weeded once at the end of the rainy season (September). The tending management should be strengthened within 3 years from the second year. The method is to take seedlings as the center to remove shrubs and weeds in the range of 1 meter in diameter around the tree plate, combined with soil cultivation and fertilization. Once a year before and after the rainy season, it is better to add one more time in the middle if possible. Fertilization: combined with soil loosening, weeding and hole expansion, 150-200g compound fertilizer was applied to each plant to promote the growth of trees, make them close into forests as soon as possible, and reduce weeds. Pruning: Huali has low branches and strong lateral branches. pay attention to pruning branches and cultivate good rod shape when tending. However, it should be noted that in the first-2 years of the young forest, do not cut off all the lateral branches too early and excessively. It is necessary to leave more branches and leaves to increase photosynthesis. With the growth of the tree age, the young forest gradually grew taller and then gradually pruned upward. In this way, it is beneficial to increase the photosynthesis of the leaves of the young forest, and contribute to the growth of the young forest and the development of the root system.

5. Prevention and control of main diseases and insect pests: there are common branch and leaf disease spots in the seedling stage and young tree stage of Dalbergia odorifera. It spreads rapidly in the rainy season, and in severe cases, the whole leaves are black, resulting in a large number of leaves falling off, seriously affecting the growth of young trees. In addition, anthracnose will also occur on young leaves and shoots, and anthracnose will also occur on young leaves. Small round brown disease spots appear on the leaves, with black spots on them, and black on the young branches, gradually drying up. The above two diseases were sprayed with 70% mancozeb wettable powder or 5% methyl topiramate 500 times, once every 7 days for a total of 2 times 3 times, all of which had a good control effect. Artificial young forest, the main harm is longicorn beetles, damaged young trees often cause wind or death. It is the most effective way to control longicorn beetles by using 90% trichlorfon or 50% phoxim 300 / 400 times liquid, injecting it from the wormhole with a veterinary syringe and then sealing the hole with cotton balls during the larval stage.
