The choice of afforestation sites should be at an altitude of 2,000 to 2,800 meters. The slope is gentle, and the slopes are mainly shaded and half shady, and the soil is better grown on soils with deep, moist, loose and slightly acidic soils.
The detailed site preparation time is 3 months to 4 months before afforestation. The method of site preparation is based on burrowed soil preparation in the mountains. The specifications are 50 centimeters, 50 centimeters, 50 centimeters, and the density is 2 meters and 2 meters. During the site preparation, the topsoil and the soil and soil are piled separately. When backfilling, the topsoil shall be filled first, then the soil shall be backfilled, and the base fertilizer shall be applied. The backyard shall be filled with holes to be planted. The backfill time should be prior to afforestation.
Afforestation methods Afforestation time is from June to August when the rainy season approaches. The choice of rain, drizzle, or rainy days before the rain should be done sooner rather than later, or it will be difficult to ensure that the growing seedlings will grow over the winter. When planting, first dig a hole larger than the nutrition bag in the planting hole backfilled with topsoil, and then tear the bottom of the bag seedling and put it into the hole. Cover the nutrition bag again with cover soil, and step on tightly; pay attention to the moderateness and fill in the depth. A little more than 1 cm above the mouth of the bag should be suitable for soil.
In the three years after tending and afforestation, weeding, ripping, and fertilization are conducted twice a year, from May to June and from August to September. The depth of cultivating loose soil is 10 cm to 20 cm, slightly shallow in the first year, deepening year after year; near the saplings slightly shallower, deeper outside.
Pest control Prunus armandi is mainly harmed by pine borers in Huidong County, often causing discoloration of foliage, leaf curling or worm formation, and affecting the growth of trees; at the same time, aphids secrete honeydew and stain the foliage, which not only affects the normal photosynthetic The effect will also induce the occurrence of coal pollution. Use 5% Chuanbao No. 3 powder, 2.5% of deltamethrin 5000 to 10000 times liquid or insecticide oil No. 1 150 to 500 times ultra-low spray control.
