Below 25 degrees. 2, site preparation. Site preparation is best done one or six months before afforestation, until it settles naturally. Weeds, shrubs, tree shrews, etc. on the ground must be cleaned up before site preparation. According to economic conditions, you can choose to fully excavate or not. According to the set density (74 to 110 per acre), it is best to embed a certain amount of basal fertilizer in a hole size of 505,040 cm. In areas with steep slopes, it is necessary to integrate the soil and pay attention to prevent rainwater from escaping. Point three: planting a good seedling Generally choose to plant a forest from December to March of the following year. Before planting, it is best to use yellow mud pulp root for root seedlings (micro-aeration powder can be added to yellow mud slurry), backfill holes in topsoil when planting, and soil (sterile soil) colonization when planting, and the root system should be naturally stretched when planting. The layer is compacted and then drenched. When grafted seedlings are planted, they must not be planted too deeply, nor too shallow, and the grafting interface can be flush with the ground. When planting seedlings, care should be taken to tear off the non-degradable container cup and compact it from the surroundings to the middle. Point four: manage good forest 1, Pei. After the planting is completed, it is best to timely earthen the chicken nests around the seedlings to facilitate water conservation. 2, surface coverage. Cover the tree shrouds with straw or other weeds and cover it with a thin layer of soil to help keep it moist. 3, replanting. Unviable acupoints should be replanted with strong seedlings or large seedlings of the same age. 4, tending. During the first four years after afforestation, every year from May to June and from August to September, they will have to soothe each time. After that, each year tends to raise once. Before the winter, the forest land cannot have weeds to prevent forest fires. 5, fertilization. Planting can be done in the same year without fertilization. After planting for the first 2 to 3 years, before the new shoot sprouts in March, two urea-fertilizers are applied per plant, and in November, the farmer's organic fertilizer is applied.
