2. Planting method: The seedlings of citrus seedlings should be non-toxic, disease-free, healthy and nutritious cup seedlings. It is recommended to choose grafted seedlings from citrus reticulata. The number of planting rows should be determined according to the terrain. If it is planted in mountainous areas, horizontal planting rows should be opened around the mountain, and gradient gaps should be formed between rows. One row of citrus should be planted on each slope, and the "Pin" type planting should be implemented. The width of each ladder is 3 meters or 6 meters, and the spacing between plants is 2 meters; The suitable size of the planting pit is 60 cm× 60 cm× 40 cm, which can achieve high yield per mu 1 1 1 plant. If it is planted in the field, it is necessary to raise the border and dig the drainage ditch. Planting in a single row away from the border, the planting pit is located in the middle of the border. For plots with good drainage, planting in large border can be divided into two rows, with row spacing of 3m× 3m or 2.5m× 3m and ditch spacing of 6m. The specifications of the planting pit are 60 cm× 60 cm× 40 cm, and 74-88 plants can be planted per mu. The number of oranges planted before the Spring Festival can reach 3-5. Citrus planted in autumn from September to165438+10 can reach 4-6 branches in the coming year.
3. Fertilization management For the newly planted citrus seedlings, it is necessary to apply sufficient organic fertilizer, thoroughly improve the foundation, ensure two buds in spring, and apply 5- 10 kg of bio-organic fertilizer to each plant at the bottom of the planting pit and mix well to form a funnel-shaped layout. After planting the seedlings, sprinkle 0.5 kg of Fu 'an at a distance of 40-50 cm from the trunk.
