The extension branches of main branches and side branches are moderately short; In order to keep the growth balance of main branches and side branches, weak branches should be lightly cut and often left; Long branches sprouting in rhizosphere, at the base of big branches or near wounds can be cultivated as fruiting mother branches or used for regeneration when branches are missing or space is large, and those that cannot be used should be thinned out as soon as possible.

Garden selection
Ficus carica is drought-resistant and waterlogging-resistant, although it doesn't require much soil. Therefore, the establishment of Ficus carica orchard should choose the beach with high terrain, good drainage and thatch growth or the sloping land in the seawall. According to the ecological adaptability and existing distribution of Ficus carica, the area south of the Yangtze River should be suitable for conventional cultivation. No matter in hilly and mountainous areas or plain areas, general cultivated varieties can grow and develop normally. Such as watering overwintering water, windbreaks, windbreaks, covering grass on trees, and raising soil on trunks, can safely overwinter.
In the area north of the Yellow River, in addition to selecting varieties with strong cold resistance or protected cultivation, it is generally necessary to bury trees in the soil to safely overwinter and grow normally. The area between the Yangtze River and Huaihe River can be regarded as a sub-suitable area for conventional cultivation, and it is necessary to choose cold-resistant varieties for normal wintering. Only by implementing winter cold protection and selecting cold-resistant varieties in the area between Huanghuai and Huanghuai can normal growth and development be achieved. When figs are cultivated in coastal areas of Jiaodong with maritime climate characteristics and places with special microclimate conditions, appropriate overwintering protection measures should be taken according to the low temperature in winter.
Planting technique
Figs planted in other orchards tend to be shrub-like with short spacing (1-3m). In warm subtropical and temperate coastal areas, figs grow into big trees, and the planting distance can be increased to about 5-8 meters. With people's continuous understanding and purposeful development of Ficus carica, dwarf close planting cultivation has been developed, and the row spacing has been reduced to 2m× 3m, with planting11plant per mu.
Saline-alkali land can be furrowed for border planting or dug for planting. The width of the border is 3.5 meters, the width of the ditch is 50 cm, the depth is 60 cm, the spacing between plants is 2-4 meters, and 50- 100 plants are planted per mu. In production practice, there are also plans for close planting, with the plant spacing of 2m× 3m in the early stage and 4m× 3m and 4m× 6m after sealing. Under the compound cultivation system, the planting distance of figs is 4m× 6m, and vegetables, medicinal materials, flowers and melons should be intercropped reasonably. What kind of density to choose depends on its site conditions, seedling price, management technology and level. In general saline-alkali land and suitable areas, we can choose close planting and planned close planting, and in suburbs and areas that need wintering protection in winter, we can choose compound cultivation mode.
